IDK exactly but I'd guess about 8-10 years, now.

@@AirPurificationEducation If the unit is from October 2018 manufacturing date - would you say that it is likely the new edition?

@@Omnisci314 Oh, Goodness, yes... the "new" fan upgrade hasn't been "new" for about a decade now, LOL!😆

@@AirPurificationEducation Thanks a lot for the input. I have an opportunity to by a pre-owned one that has that manufacture date - October 2018, with 90% full filters, for $300. Would you recommend? If yes - how would I make sure that the filters installed are genuine?

@@Omnisci314 IDk, you'd have to look at the filters themselves - that said an IQAir HPP for $300 without filters is also a decent buy - so long as the unit is in good shape... - ya just get new fitlers for about $350. Also, I think the vast majority of owners will use real IQAir filters in their units.... it just doesn't make sense to go cheap on the actual filters...

Aeris max CFM is 390. 390 x 60 = 23,400 total cf./hr. Now, 23,400 divided by 8 ft. ceilings = 2,925 sq. ft. for 1 ac/h. And divided by 4 = 731.25 sq. ft. w/ 8 ft. ceilings. So, on high, it will get 4 ach in 731 sq. ft., 390 CFM is a lot.

Thank you for your feedback - I appreciate it!😄

I'd say - if you have 8 ft. ceilings in the room, then low speed will get you 2 air exchanges per hour, but I prefer people get 4+ AC/Hr. if possible. So, I'd put it on Medium and you'd get 9 AC/Hr. which is FANTASTIC! Thanks!

@ thanks! There is a huge difference in noise level between 2 & 3. No way I could keep it on 3 all the time. Only when necessary. These are some heavy duty units!

@@OrthodoxChristian27 Yeah, I think they hit a Home Run with these units and I plan on making a video on them in a few months. 👍

@ so of if I have a 250 square foot bedroom, How do I determine the number of air exchanges per hour on the medium setting? With the V414. Thanks.

@@OrthodoxChristian27 Good Question. Here is how we can figure out the number of air exchanges an air purifier provides in a given cubic footage. 1) Cubic Footage: L x W x H. 250 sq. ft. x 8 ft. ceilings = 2,000 cubic ft. CFM of V414 on 3 Speeds (WITH the Filters installed - oftentimes companies will provide CFM numbers WITHOUT the filters installed, LOL): Speed 1: 40 CFM Speed 2: 200 CFM Speed 3: 260 CFM 200 CFM x 60 Minutes = 12,000/hr... 12,000 divided by 2,000 = 6 - so, in a 250 sq. ft. space w/ 8 ft. ceilings, you'd get 6 air exchanges per hour on medium speed with the unit.

Thank you for your feedback👍 Some of the more important points to consider I think, include: 1) None of the HEPA units in this test are Upper Echelon Air Purifiers (IQAir, Airpura, Aeris) - so we are looking at "Mid Tier" HEPA solutions and lower. 2) "Then you finish by saying we need to worry about small particles, but these tests show the CR box performance is similar and even arguably better overall than HEPA even with small particles less than 1 micron." A: "Small Particles" - I'd say UFP - Ultrafine Particles - are by far the most dangerous to humans according to recent research and they are .1 to .003 microns in size and make up 90% of the particles in the air we breathe. So, on the particle filtration side - THAT is a HUGE Consideration and oftentimes the #1 issue folks are gonna want to filter out of their environment. These Amateur test results by RTINGS.com don't account for UFPs. The CR Box won't filter UFPs as well as the upper echelon solutions and it would be super interesting to see how it would do vs. the 5 Mid Tier HEPA units that filtered better at .3 and .5 microns - I think the graphs for those 5 solutions would be more and more in favor of the HEPAs filtering better - if they were able to accurately test for UFP. . 3) "If pollutants keep getting introduced then initial speed of elimination is the more important factor, CR boxes are a much more active way to filter, and with computer fan designs use much less power and are much quieter so can be used at full power 24/7. " A: I think there is a lot of truth to this in the real world as there are no such things as 100% Total Air exchanges in a room... however, I've become a believer in DPCA - Direct Path of Clean Air - meaning - the best filtration solution in a space is oftentimes going to be the one that can blow clean air on you, or in your general direction vs. trying to achieve "partial" air exchanges. For example, I have an Airpura V414 sitting 2 feet from me and it blows clean air out on me - with a Super HEPA filter 99.99% at .3 microns.... + it has 8 lbs. of carbon. 4) CR Boxes = no carbon... Wildfire smoke and smoke in general have thousands of harmful chemicals in them and filtration solutions really need a lot of carbon to help absorb them. 5) CR Boxes ARE great for woodworking type environments as a "partial" solution, IMO. Filtering large particles out of the air quickly is their forte... they are like a large, powerful, pre-filter - to a certain degree. 6) I agree a CR Box type solution with quiet - low energy fans - with higher MERV rated filters, like maybe MERV 16... are interesting, as well. Thank you!👍

They haven't rectified it in the US as the word "HEPA" is no where to be found on the product page nor in the filter descriptions: levoit.com/products/core300-air-purifier?srsltid=AfmBOoq7SXZGN2LWMrOYDgTgeTE7RbbCPeSjz_3BSFdFgLNKqecuirex And on Amazon they still state the filter is only at "HEPA grade" when running on the lowest speed/Sleep Mode - which I think is like only 40 CFM: "The Levoit Original Filter is HEPA-grade while operating in Sleep Mode, as tested by an independent lab." So, I'd say if the Levoit website in the UK describes the unit and filters as "HEPA" or "True HEPA" - then I think you got a HEPA filter in the unit. But if it doesn't - then, I think they are still using the old packaging to ship the products that say "True HEPA" all over the box and manual... which is what my packaging said - even though it was 4+ months after they agreed with the BBB to stop marketing it as having a HEPA filter in it.

@ yeah the box and Amazon listings both say h13 true hepa filter. The box looks brand new tbh. I’m assuming levoit just upgraded the filter? Seems strange though.

@@Lord_Mangzz Yeah, my box and packaging was brand new, as well, but when I say "old" - I mean, the packaging said "HEPA" and "True HEPA" all over it. Even though, they were supposed to replace it without the words "HEPA" on it. Now, the BBB is in the US so perhaps they can still market and advertise it as being "HEPA" in the UK without an issue is what I'm kinda thinking. Because if they have True HEPA filters in the UK for the product - then it should also be available in the US, as well... .I'd guess. If not now, then perhaps in the near future?? We'll see.

yes, for particle filtration

@@AirPurificationEducation so medical pro is better, right?

@nightking3369 Yes, the Medical pro is better for particle filtration than the 3 in 1.

@AirPurificationEducation ok thanks, but is there a reason why you would still prefer the 3in1 over the medical pro. is the medical pro louder?

Because I never recommend the Plus unit - as I've had several customers in the past say they smelled a musty odor coming from the unit after 6 to 12 months.

@@AirPurificationEducationgood to know! Thank you!

Yes, I think an air purifier can help you with this issues. Of the ones you mentioned - I'd lean towards the Winix, Philips and even a Levoit Vital 200S.

@@AirPurificationEducation Would you recommend that I buy the Winix Zero Pro?

@@emrekarakocx Sure - it is somewhat similar to the 5500-2 so yeah, that would be a good investment. 👍

Yeah, I always supersize my air filtration solutions for my cubic footage - so, if you go with the larger unit - you can run it on a lower speed and it will be quieter and you'll want to get at least 4 air changer per hour, if possible.

@@AirPurificationEducation Thanks!

@@AirPurificationEducation The other question i had is should you leave your filter running 24/7? Seems like common advice but it doesn't add up from my understanding. Doesn't it only take 15 or so minutes to filter a room (and inversely to pollute) so if you aren't home then there really is no benefit to keeping it on, as its extra electricity cost and extra wear on the filter. Wouldn't it be better to have a scheduled off timer or something when you aren't at home.

@@jesselam5867 Yeah, people can do whatever they choose when it comes to this issue... But, I didn't buy my air purifiers to "save money" or cut costs... I made an investment in my health - long term.... So, I am gonna run them 247 as I want the cleanest air possible.... and if they ain't running - then a lot more dust is gonna accumulate everywhere in the room and it will get kicked up into my breathing space as I move around the room... I have an expensive water filtration system in our kitchen, and I don't just use it "some of the time" so I can save some money on replacement filters... I use it ALL the time.... So, that is how I currently feel about this. That said, do whatever you want, lol!😆

1) I never said I was an "Expert" as there is NO such thing as an expert in this industry. There are too many units on the market and too many new ones hitting the market on a monthly basis for anyone to have substantial experience with all of them. 2) I have 17 years of real-world experience as a professional indoor air quality consultant (like it says on my banner). I've dealt with over 100 air purification solutions. And I've dealt with thousands of customers in those 17 years. So, I have a lot of real-world consulting experience. 3) If you don't know when to use the word "you're" vs. "your" - then you have bigger issues to worry about than me "sputtering nonsense", LOL!😆

You are asking for a lot for less than $300. I think maybe you could try the TruSens Medium unit Z-2000 but get the filters with more carbon in them: www.trusens.com/p/air-purifier-replacement-filters-uv-bulbs/dupont-odor-voc-filter-true-hepa-for-medium-air-purifier-afhz2000-smk01-1/ That said, I can make no promises it will solve your issue - but you need a good amount of carbon.... and carbon tends to be expensive.... And you may be buying new filters every 5 months or so depending on how much you run it.... Good Luck!

1) So you find "extreme bias" in my videos but you don't find extreme bias in Mr. Corsi running his own test on a CR Box vs. some HEPA options and trying to pass it off like there isn't a severe conflict of interest? 2) I have 17 years of real-world experience as an indoor air quality consultant (like it says in my banner). And I have dealt with over 100 filtration solutions involving thousands of customers and their feedback. 3) I work for myself. 4) "In truth, consumers first have to determine what they are trying to filter before they can arrive at an appropriate filtration solution." - Yup, that would be one of the variables.

Nah, THEY/RTINGS compared 26 filtration units and only 1 was $1,000 - the Dyson. The other 4 that filtered better were way below $1,000... did ya even watch the video😆

He has some valid points, I wouldn’t say it’s a joke; but I think both sides of the argument are very passionate because they both have pros and cons tbh. Personally I’m feeling like CR box with computer fans might be the best for me at home.

@@AirPurificationEducationappreciate you responding to comments, making a video takes more effort than commenting so don’t ever let anyone get you feeling upset in comments, we’re just peasants here 😂

Yeah, someday an affordable "super duper all inclusive" Air Quality Tester will be available - but unfortunately, we ain't there yet.

Thank you for your inquiry. That is a GREAT deal on the unit, for sure. I paid $750 for mine a while back... and it originally entered the US market a few years ago at about $1,100 - If I remember correctly. It is hard to say "no" to a $300 price point on a new 3 in 1. Statistically speaking there is probably a 98% chance you won't have a problem with it filtering for at least 2 years. Which I think is the warranty for the unit, last I checked. I don't care about the sensor/app. issues, at all on air purifiers - I just want great filtering units that I can run 247. So, not having the app. working isn't an issue for me, at all. So, $300 is an AWESOME deal on this unit - new, and I'd probably take my "chances" on it. Good Luck!👍

@@AirPurificationEducation Thank you for your answer, Doug, I appreciate you being so candid. Can I bug you with a few follow-ups? 1) I know you said iRobot issued a statement that they will continue to service their purifiers. Do you think there's a chance that we will see a scarcity of replacement filters, or do they continue to manufacture those for existing owners? 2) I'd be using this Aeris in my living room which is about 575 square feet, but there is no door that separates it from the rest of my house (an addl 500 square feet on that floor, and an open stairway that leads up to an addl 750sq ft). In these instances, where rooms are not truly separate, I have to believe that the purifier is less effective, even if you're putting other purifiers in the other rooms of the house. Or, am I over thinking this? 3) My living room would have this "elite" filtration (as you refer to it) where ultrafine particles are more likely to be trapped. Out of sheer enormity of cost, I'm not putting as effective machines in my other rooms. I would imagine that having the Aeris going in one room is better than nothing, right? At the heart of that question is: do i really need this elite machine in my main room when I'm not being as careful in the rest of my house? 4) I know you have your machines going 24/7. Is that to say that you don't believe in the philosophy (as other sites mention ie. Wirecutter) of turning them on high for an hour to clear the room, and then setting them to a medium speed thereafter? is 24/7 completely necessary for true efficacy? Thank you again for you time and patience answering these questions! Is there a place we can donate to your channel?

@@MattJablin 1) I think they are in trouble as revenues have plummeted for 4 straight years now... and 2025 is a HUGE year for their company and they are not focusing on the air purifiers at all... so yeah, anything is possible. 2) Yes, the units will be less effective in open spaces connected to other open spaces - stairwells, etc. 3) Yes, better than nothing. Do you need it? No. Do you want better air quality? - then yes. 4) This depends on the overall room size and what level of filtration one is trying to accomplish. I invested in my machines to improve my air quality so yeah, Imma run them 247 and try to get as many air exchanges within reason... I have a $5,000 water filtration system called Kangen Enagic (not to brag - it was my wife's doing and I had no say in the transaction, I think her mother got a commission off of our sale, lol! )... But, I wouldn't want to get "less clean" water to drink at any point in time... so, I feel the same with the air filtration issue, as well. 👍

@@AirPurificationEducation Thank you, again. Would you go Aeris 3 in 1 in a large living room with my situation over a Coway Airmega 400 even if the Coway has a bit more oomf and can get more exchanges in? As a viewer, I'd selfishly love a video at some point talking about purifier placement, what to do with open spaces that aren't door'd off, running multiple smaller units vs. one large unit, etc.

Different consumers have different tolerances for air purifier white noise. I generally like the white noise coming from air purifiers as it drowns out other sounds/noises I don't necessarily wish to listen to. I currently have a V414 sitting less than 2 ft. from my head running on medium speed and it isn't an issue for me. But that is me. I think some consumers want the "Quietest" solution out there - and value that over filtration performance. So, I think, Blueair and RabbitAir make fairly quiet units, in general. But, they won't filter as well as Airpura, IQAir, Aeris, etc... I value filtration performance over noise levels by a WIDE margin... so different people can have different opinions on this. I just unboxed and started running a TruSens Z-1000 (small unit) and that thing is definitely louder than this V414 on high speed. So, there are some variables involved - it depends on how sensitive each individual is to different noise levels.

OK Cool - can you please tell me: 1) What is the square footage of the room(s) and the ceiling height(s) you wish to put a solution(s) in? (cubic footage). 20 x 9 x ? ***Of Note: Air filtration solutions work best in rooms/spaces with closed doors so they can attempt to achieve hourly air exchanges… preferably about 4+ ACH. But there are also some other variables involved, as well. 2) Are you chemically sensitive? 3) Are you super sensitive to the contaminants in your environment besides chemicals? For ex. you have strong dust allergies and you sneeze and cough constantly… or you are taking medicine for asthma… or you get chest pains from pet dander in your environment, etc. 4) What country do you live in? 5) Are there any other additional variables/issues with you/others or your environment that may be relevant to selecting an air filtration solution? Thanks!

Thank you for your question. The Whirlpool Whispure 510 was the #1 choice of Consumer Reports over 10 years ago and I believe it was about $300. The dealer that I worked at sold many of those units because CR ranked them #1. I think it is a very good unit for the money. That said, it doesn't have a good seal inside it between the HEPA filter and the inside of the unit - so, dirty air will escape around it. And it won't be strong for Ultrafine particle filtration. And it doesn't have much carbon so... it won't be super strong for VOCs/Chemicals, either. I think I can tell you what is better than what you have based on some questions - and you could decide if you want to upgrade the solution or not: 1) What is the square footage of the room(s) and the ceiling height(s) you wish to put a solution(s) in? (cubic footage). ***Of Note: Air filtration solutions work best in rooms/spaces with closed doors so they can attempt to achieve hourly air exchanges… preferably about 4+ ACH.

Awesome - I appreciate your feedback - thanks!👍

@ I have 3 Intellipure and 1 Mila air purifiers in our home as we live in SoCal and we have family members with asthma. I was wondering if you’ve had any experience or opportunities to test the performance of either of these products. They seem to do a good job but have been recently looking to purchase a particle meter to check and verify, and came across the Temtop brand but hadn’t heard of them before, after your review was the first I came across. Needless to say, I will keep shopping and am open to suggestions. Thanks!

@@evolv.e I currently think the Intellipure and Mila solutions are decent for particle filtration but not upper echelon.

Yes, I met the original owner of Allerair several years ago when the company I worked at became a dealer for them. And he seemed like a nice gentleman. The company was sold a few years ago and the new staff provided terrible service levels for their customers AND dealers. So, we discontinued our relationship with them - which was extremely rare for us to do. I even had a few AllerAir customers call me and complain about how terrible the service was from the manufacturer and they weren’t even our customers, LOL! Therefore, I do not recommend them to consumers.

@AirPurificationEducation wow that's a bummer. Thankfully I haven't had that issue yet.

@@jessejordan310 Yeah, I also take the "customer experience" into consideration for my recommendations, as well. I don't want to send someone into a potential "ambush" - as they may blame ME. And ain't nobody got time for that, lol! 😆

Are you chemically sensitive? Meaning, you tend to not like perfumes or colognes?

@@AirPurificationEducation thank you for your reply! I thought i answered before but don't find my reply anymore. I don't think I am chemically sensitive, i don't love or use perfumes but they also don't bother me very much. If the air is clean and my nose not stuffed I might be more smell sensitive than others. I asked Claude (like chatgpt) about the issue it it said it is normal for new unit to off-gas chemicals that got stuck during production and that it needs to be broken in for 1-2 weeks. Have you heard this before?

@@franzsymalla3635 It should be "broken in" within 48 hours, IMO - at the most... I've had Austin Air units off gas for 1 or 2 hours but that's it. I just started running an Airpura V414 last night and it may have smelled just a little bit - barely, but today I don't smell anything from it. That said, a few years ago we got an Aeris TVOC unit that off gassed so badly we had to turn it off.... so it depends... I think Aeris was made in Switzerland until iRobot purchased them - and then, I think they transferred manufacturing over to China.

I have had some folks ask me in the past about that brand and this is what I currently email them: ******************************************** 9/16/24: Have you seen or tested any of the idaptair 2.0 models from airoasis? I can’t seem to find any reviews or videos other than what seem to be from the company themselves or possible paid sponsorship videos. I’m curious if you think or know that these are actually high quality HEPA filtration systems? 11/20/24: Have you ever looked into the air oasis Iadapt 2.0 It claims to purify up to .05 microns. It has 5 different kinds of filters. It also seems to be popular in the CIRS community. I'm looking to get one myself but I'm looking for a second opinion on the effectiveness of those 5 filters. ANSWER: On the iAdaptAir 2.0 Pro I don’t have direct experience with this unit but I did see some videos on their older units within the past year and I just looked at their site a little… Based on that - my initial feelings are: 1. Pre-filter: I don’t see much, if any, of a prefilter for their solution so the filters will get clogged quicker and provide less CFM/airflow over the coming weeks and months. I saw someone on video pull the HEPA filters up and they were caked with dust and she acted like that was impressive but in reality, it’s because the unit does not seem to come with a good prefilter that you periodically clean - so of course, the HEPA is going to get “caked” in dust. That is NOT a good thing. It will just limit the airflow to a crawl over time. 2. Gasket/Seal: looks like you just slide the filter pack in (straight down) - the seal does not look elite - just OK. Also, it does not seem like there is a strong seal above the filters with the top of the unit. 3. Carbon: Looks like the carbon component is sandwiched between the HEPA filter and the silver microbial filter. There does not seem to be a lot of carbon so I would not expect it to be a good solution for odors/VOCs for an extended period of time. 4. The largest unit is $999 and the replacement filters are $229? That ain’t cheap. 5. CFM/Airflow: They really stress the high airflow rate of the unit and a good amount of CFM is a good thing… however, I think the airflow will be reduced on this unit somewhat rapidly due to the lack of a good prefilter… So the unit will perform much better on day 1 than say day 100 - for particle filtrations, IMO. Conclusion: I would expect it to improve the overall air quality in a space - like most all air purifiers. It will definitely improve the overall air quality but it won’t perform in an elite manner, IMO. I would say it is a “Good” air purifier for particles but not “Very Good” or “Great/Elite”. These are my initial/current opinions. 11/20/24 Updated: 1) I looked at this video with Jon Bennert - the Owner, and he talks about their newer units. He stresses the CADR which I am not a fan of as it oftentimes provides misleading information on air puriifers and it is generally overstressed in the industry (by companies with lower echelon filtering air purifiers): kzbin.info/www/bejne/sHKQZ3t9qqZrr8k&ab_channel=AirOasis 2) If you’ve seen my video: “What THEY Tell You About Air Purifiers is BS!”: kzbin.info/www/bejne/sJaqkmxmmptoiac&ab_channel=AirPurificationEducation Then you know the LAST people we can trust to provide us with legit graphs, test results and opinions on air purifiers are the actual Owners/Employees of the air purifier companies. 3) LinkedIn: Here is his LinkedIn page: www.linkedin.com/in/jon-bennert-462ba2125/ Seems he’s been the CEO since 2004 - which is a pretty long time. That said, it is extremely light on his experience and background… engineering background? Education, etc. I mean, what has he done in the past? Perhaps, he has just focused on this company for the past 20 years… and I’m cool w/ that, if that’s the answer. Either way, I take it generally as a positive variable, in that, it doesn’t necessarily mean they have elite solutions however, I provides some assurance to me that the units are probably, not causing damage to customers. As they have been selling a decent number of them through the years to support upwards of 20 employees. So, I’ll carefully take this as a positive. Here is his dad’s LinkedIn page - seems he is the COO and CoOwner since Dec. 2022. www.linkedin.com/in/jeff-bennert-84149616/ Here is the company page: www.linkedin.com/company/air-oasis/people/ Seems they have 17 or so employees - which is a decent amount, I think. 4) Video of filter installation. In the 6:23 minute video here: www.airoasis.com/products/iadaptair-2-0-pro We can see him pull the filters out and we can see a gasket around the sides - top and bottom of the filter. A) GASKET: From what I can see, I think the gasket itself, is just OK… not like the gasket of a Camfil City M filter. So, I think the material the gasket is composed of is just OK. That said, the arrangement is better than most average air purification solutions. Not elite but better than most decent units. B) SEAL: The seal between the gasket and the inside of the unit appears to be better than most average/decent units… they made an effort to improve this seal. I can’t totally see how well it is sealed - especially at the top of the unit but, at least they made some effort. C) CARBON: I don’t like the carbon coming after the HEPA filter as I think you can get some carbon particles in the air… even with the Silver Ion component coming after it. There does not seem to be much carbon involved so I do not think this will be great for odors/VOCs… and it won’t last long. D) PREFILTER: I don’t really get a good look at the prefilter on the newer units - seems the older units had a “Dust Guard” which resided on the outside of the unit that you could clean off… which looks OK as a prefilter but not a great prefilter solution… maybe not even average for average solutions. A good prefilter solution is very important for the long term airflow of the units… So, I don’t even see him/them mentioning the prefilter on the newer units. E) MANUALS: The Online Manuals currently appear to be for the older units so IDK about some of the specifics of the newer units… www.airoasis.com/pages/manuals?srsltid=AfmBOoqtv0KG6e-4GeOJwYkMBbbvh7xim6Wal7Y6the4JpQt8GYCddTO F) BIPOLAR IONIZATION: I am not currently a fan of ionization for various reasons. G) NOISE: Seems the units are fairly quiet vs. other air purifiers so that will probably be attractive to some consumers. F) CONCLUSION 11/20/24: I think they have made a decent effort to improve their overall offering/solutions. Also, I think the newer units have more airflow which is generally a good thing. All in all, I currently think they will filter particles at a decent level and I do think they will improve the overall air quality in a space. And I’m gonna say they are probably better than the average air purifiers on the market for this. Although, I think it is possible they will get less airflow over time as I don’t currently think their prefitler component/solution is very strong. Also, I do not think they are elite like IQAir, Airpura, Aeris type solutions - for particle filtration and I don’t think they will be strong for Odors/VOCs/Chemicals for any length of time. G) COMPARISONS: G1) For $299 we can get an iAdapt 2.0 - Small. And for $370 we can get a Rabbit Air BIOGS 2.0. which I like better. Also, we can oftentimes get a Coway Airmega 300 for about $359 (they run a lot of sales on it) which I like a lot more. And right now, I can see it on Amazon for $328. G2) For $449 - we can get an IAdapt Air 2.0 Medium. But for $535 - we can get an Airpura R414 with 8 lbs. of carbon and a Super HEPA Filter that filters (99.99% at .3 microns) and is better for Ultra Fine Particle Filtration. Plus, it is 9 inches shorter and about 2 inches wider. I believe it will filter particles and VOCs/chemicals much better. G3) We can also get an IAdaptAir 2.0 Pro for $749. For $949 we can get an IQAir HealthPro Plus with better UFP filtration. For $770 we can get an Airpura I700 with 100 sq. ft. of HEPA material and it will filter particles better. And for $750 we can get an Airpura R600 with a very good HEPA filter and 18 lbs. of carbon so it will filter better for particles and much better for VOCs/chemicals/odors, etc. So, those are some options in the same general price ranges which I currently feel are superior filtration solutions.

@@AirPurificationEducation wow! quite a reply, thank you. a couple of points; they do suggest that you can vacuum the filter to remove dust build up.. I have just gotten the pro,, mainly due to the low 24 decibels on low setting and the uv aspect. I question the efficacy of the uv due to the rate of air flow past the lights. Mine shows a particle count of zero, which seems curious because I do have lots of dust build up throughout the house. My main reason for wanting an air filtration unit is that when the house was build, i didn't reject the moldy lumber used and I get a lot of air penetration through electrical plugs etc. Which leads me to believe mold particles are coming into my air space. they offer a sixty day trial period,,, what would you suggest for my needs here. I live on the northern CA. Coast, where it can get wet and foggy that supports mold etc. Thanks

@@van123446 Can you please tell me: 1) What is the square footage of the room(s) and the ceiling height(s) you wish to put a solution(s) in? (cubic footage). ***Of Note: Air filtration solutions work best in rooms/spaces with closed doors so they can attempt to achieve hourly air exchanges… preferably about 4+ ACH. But there are also some other variables involved, as well. 1B) Room #1: 1C) Room #2 (if applicable) etc.: 2) Specifically, what is the #1 issue you trying to filter out of the air (dust, allergens, odors/chemicals)? I think you are most interested in filtering mold particles. 2B) What is the #2 second most important? - if there is one... 3) Are you chemically sensitive? 3B) MCS or Chemical Sensitivities typically mean that Colognes and Perfumes bother people to varying degrees… 4) Are you super sensitive to the contaminants in your environment besides chemicals? For ex. you have strong dust allergies and you sneeze and cough constantly… or you are taking medicine for asthma… or you get chest pains from pet dander in your environment, etc. 5) Are there any other additional variables/issues with you/others or your environment that may be relevant to selecting an air filtration solution? Thanks!👍

@@AirPurificationEducation hi, the square footage is about 1200 , a great room with attached kitchen, in the shape of a T. The ceilings are about 16 feet. mold, and I suppose possibly fiberglass particles from the insulation, since the air is coming down the walls and coming out of wall electric outlets and light switches is what I'm really only concerned about. if I stay in hotels, carpets and mattresses etc create stuffiness and bags under eyes.. but only in hotels. I also just read in detail about the air dog units. Do you think they are as effective as they claim? I like that there are no filters to replace. but when I see a carbon filter that you can see the daylight through, I have to wonder.. thanks again, Van

@@van123446 Hey Van, 1) “ they do suggest that you can vacuum the filter to remove dust build up..” If they are talking about vacuuming the HEPA filter - that is not an ideal setup… as none of the top echelon filtration solutions have customers vacuuming the HEPA - only the prefilter. If dust is getting caked on a HEPA filter then consumers will not be able to simply vacuum all the dust out of the fitler and retain it’s original airflow - some particles will definitely get embedded in the HEPA and lower the airflow. 2) OK, so you have 1200 x 16 = 19,200 cubic ft. which is like having a 2,400 sq. ft. space with 8 ft. ceilings. So, it is a big space cubic footage-wise. In order of filtration - best to last - with the goal of about 4 air exchanges per hour. A) Airpura UV714: www.airpura.com/products/uv714-germs-and-mold-super-hepa-99-99-efficient-0-3-microns-air-purifier?_pos=1&_sid=6469f8d7a&_ss=r I asked Airpura for their thoughts and they said, “For starters, they (Air Oasis) have 1.27Lbs of carbon. What's the point? A good bed of carbon is needed for the fumes, mycotoxins released from the mold/spores... They use an H13, which is fine but if you are concerned with mold spores in the ambient air, H14 is recommended.” They recommended a UV714 but your space is a little larger than 16,000 cubic ft. So, 1 unit is undersized. 2 would be better. B) Airpura R414: www.airpura.com/products/r414-the-everyday-air-purifier?_pos=1&_sid=43559b305&_ss=r This also has a SuperHEPA filter in it like the UV714 - which filters better than HEPA. But these are smaller units so ideally you could put 3 in the space - 1 in each room and 1 in the middle region. These units have 8 lbs. of carbon, each. C) IQAir HealthPro Plus: amzn.to/3NIJ6Uq I’d put 1 in each room. 1 unit, by itself, is too undersized. The IQAir HPP has 5 lbs. Of carbon in it. D) Coway Airmega 400: amzn.to/3O3DHsF You would really need 3 of these to accommodate your cubic footage. The Coway 400 units have a little less than 2 lbs. Of carbon in them. So, these would be some suggestions - you have a lot of cubic footage. You would get a 10% discount with Coupon Code DZAIR10 on the Aipura solutions. Please let me know if you have questions.

I have never heard of this company before so thanks for bringing them to my attention. I will take a look around and give you my knee jerk reactions/opinions on what I see. Let’s look at their website.. 1) Mini Air Purifier (Room Size Small (up to 200 sq. ft.): atmosc.com/en-us/products/atmosc-mini-destroy-pollutants A cylindrical shaped air purifier - Looks like an inexpensive Winix unit - but made in China - type quality. $108 US dollars… “PFF-9 Technology: Activated Carbon, Medical Grade HEPA13, PM 2.5 sensor and Night Mode” Ohhhh…seems like we get A LOT for $108, LOL! FREE SHIPPING In the US and Canada is always a plus! WARRANTY: 2 years - I think that is a good warranty for the price. Airflow: CADR 120 m3/h They provide a CADR number but they are not listed on the AHAM CADR Registry so we don’t know how they tested for this delivery rate, as it was not through AHAM. www.ahamdir.com/room-air-cleaners/ “PFF-9 Technology” was trademarked and registered on Nov. 1st, 2022 by Jaeyoung Chon out of Germantown, MD. www.trademarkia.com/pff-9-technology-90534459 So, what exactly is PFF-9 Technology? On Facebook Oct. 26th 2020 it says, “ The PFF-9 technology is the world’s most complete filtration system that can eliminate viruses, bacteria, chemicals, odours and more. The sophisticated system includes Activated Carbon, HEPA, UV light and a Humidifier to remove impurities from the air. facebook.com/atmosc/posts/157959032654483/ Then it says, “Let’s take a closer look at our PFF-9 Technology” but after clicking on a few slides - I don’t see any specific explanation about it. Video1 (Aug. 19th 2020): AtmosC: Pure Air Experience with PFF-9 Technology kzbin.info/www/bejne/kJ3WaqCYfqaEoLs But they don’t explain anything about it - just basically say “PFF-9 is the best” kind of narrative… About Us Page on their Website: atmosc.com/en-us/pages/about Again, more nebulous, generalizations - “Our team consists of biologists, engineers, researchers, and scientists that have more than 25 years of experience and work continuously to revolutionize air quality systems.” They have a heading about their “Warehouse” which is kinda funny. And a typo, “Knowledgeable feld experts that lead the industry in reliable,” I think they mean “Field Experts”. Then we get the heading “The AtmosC Advantage” And again, “The only complete Air Purifcation system with the 9 Phase Filtration Formula: PFF-9” But not an in depth explanation about it. “Research backed development at the molecular level” “15 years of experience and expertise” “Team of scientists, engineers, biologists, virologists, doctors and graduate students” “State of the art facilities to enhance all areas of development, research, testing, production” “Giving back to the communities that helped in our growth” It seems like they felt the need to fill the space on their website with general jargon, to appear to be a “credible” source… but, this stuff just makes me yawn, lol! So, at this point, I am not feeling confident that they have anything special - as if they did- they probably would have explained it by now, IMO. 2) A Series: Video2: AtmosC's A Series with PFF-9 Technology - The Complete Air Purifier kzbin.info/www/bejne/paetZ6uQj9ungcU&ab_channel=AtmosCInc **At :07 they show an exploded view of the unit and it says “PFF-9 Technology 9 Phase Filtration Formula” So, I guess they are saying they have 9 different ways to filter the air with this unit. **At 10 seconds “Pre-filter” **At 14 seconds “Cat-Oxi” “Catalyzes the decomposition of VOCs with oxygen to produce water. Examples: Formaldehyde” **At 18 seconds: “Advanced Activated Carbon” “ Can absorb, decompose and remove harmful gases with a removal rate of 99% of VOCs” **So, if their carbon filter can remove 99% of the VOCs in the air - why would they need the Cat-Oxi filter? Just for the 1%? **At 22 seconds: “Antibacterial Cotton Strainer” “Inhospitable environment for bacteria. Shut down of microbial metabolism, growth and reproduction” **At 25 seconds “Advanced HEPA Filter” Removes up to 99.97% of .01 micron sized ultrafine particles. Examples include Mold Spores, Pet dander, Bacteria, Smoke, Particulate matter.” Also, they use the terminology “up to” which does not mean “it always achieves this level of filtration”. **So, they use the numbers 99.97% which is associated with HEPA filtration (99.97% at .3 microns) but they say their HEPA filter can hit this number with UFPs at .01 micron sized particles. This could be considered Elite particle filtration for a HEPA filter. What 3rd party testing proves this? **At 29 seconds “UV Technology” **At 33 seconds “Negative Ions” **At 38 seconds “Humidifier” - hmmm, I am not a fan of adding a humidifier to an air purifier. And it appears the humidifier comes last in the filtration process. Not crazy about that either. Could possibly get a dirty water/mold type issue. I’ve only seen 1 other air purifier brand add a humidifier to their unit. I generally, do not like the addition. **At 41 seconds it says the A Series can purify for up to 600 sq.ft. and provide pure air at a CADR of 488 m3/h. But the drop down menu for the A Series says “Medium (up to 1,000 sq. ft.) atmosc.com/en-us/products/atmosc-a-series-air-purifier And then, on the product page it says, “Designed by our engineers to provide the purest air. With coverage of up to 1500 sq.ft. and Active Humidification Technology.’ Then further down it says, “Purifies 1000 sq. ft. in 9 minutes”. Are they reading their own marketing? How can the video say “Up to 600 sq. ft.” but then the drop down say “up to 1,000 sq. ft.” and the product page say “up to 1,500 sq. ft.”. These are 3 totally different size ranges. That is kinda crazy and not something I see often on manufacturer websites. And “Active Humidification Technology” sounds kinda impressive but it seems like - it just has somewhat of a humidifier at the back of the air purifier. Also, the product page says, “AtmosC are leaders in homecare solutions since 2004.” but on another page it says they’ve been around since about 2014. So which is it? Another Typo at the bottom of the product page, “cleaning the air and flooris”. Doesn’t provide me with a lot of confidence in the company. 3) Then we have the AirTower RX for $2,400 atmosc.com/en-us/products/atmosc-airtower-rx The dropdown says “Large (more than 2,000 sq. ft.) but then the product page says, “For areas larger than 2800 square feet”. Seems no one is checking to see if their sizing specs. are accurate/consistent on their website. Then it says “Low Maintenance” but under that it says, “Regular filter replacements required every 4 months.” What?! It is very rare to see an air purifier that needs filter replacements every 4 months and that would be considered “HIGH maintenance” lol! There is very little information on this unit on the product page. It does not show inside the unit nor the replacement filters - nor how many… nor the cost… etc. What’s the big secret? 4) Then we have the Air Meta 360 product page. atmosc.com/en-us/products/air-meta-360 WARRANTY: There is a $399 and a $449 option and they come with only a 1 year warranty which is not acceptable at those price points. This is a terrible warranty vs. the competition at these price points. It tells me they don’t have confidence in the quality of the product line. So, their $108 solution has a 2 year warranty but the more expensive $399/$499 solutions only have a 1 year warranty? This does not really make too much sense to me. They say the 360 for $399 covers 700 sq. ft. and the 360 Pro for $449 covers 1,200 sq. ft but the specs. below are only for the 360 unit… again, very limited amount of information on the solutions. I don’t see any 3rd party certifications nor any product manuals on the product pages. We’re not really able to see inside the units to get a better idea of the overall quality. The 360 and 360 Pro both use the same replacement filter and it is only $110. Now, it comes with 14 lbs. of carbon which would be considered a lot and they claim these units come with a Super HEPA filter but they don’t specify exactly what that means. A Super HEPA filter from Airpura means it was tested to filter at 99.99% at .3 microns - better than HEPA. So, what exactly does “Super HEPA” mean to AtmosC? Also, it seems like they kinda tried to copy the Airpura “Super HEPA” concept/verbiage. Both manufacturers are in Canada. So, I don’t have a super strong feeling for this brand. It is hard for me to see how good the seals are inside the units. So, in general, their overall lack of information on the products, typos and wide range of sizing specs. do not instill much confidence in me. Therefore, I think the units will probably filter decently but not at an upper tier level. That is what I currently think.

@AirPurificationEducation thank you so much for your opinion. I had second thoughts myself. I've read some reviews on reddit some customers haven't even received their units but paid for it.

@@dj-tn6in Didn't even get the units?! Now, THAT is a whole nother level of Horrible Service. Ain't nobody got time for that, LOL!

I think MERV 13 filters in a CR Box with a lot of airflow is a good solution for woodworking environments as it will help take the larger particles out of the air quickly... but I'd combine it with a breathing mask, as well. But, by itself is a MERV 13 solution as good as an upper echelon HEPA air purifier for smaller particles, No.

I would say it can get 4 air exchanges in 500 sq. ft. with 8 ft. ceilings so I think that is a good fit... and I think 2 V414 units in 1000 sq. ft. is superior to a single large V714. 2 smaller units at 2 different locations in a larger room, in general, is better than 1 "centrally" located unit, IMO. 👍

@ great, thanks! And what is the difference between the R414 and the v414? I appreciate your help. I will be using your discount code. 👍

@@OrthodoxChristian27 They are the same with 1 exception: Both come with a Super HEPA filter and both come with 8 lbs. of carbon But the V414 comes with Potassium Iodide in the carbon so it can take more chemicals out to air and that is why I got it - I wanted the best carbon option for smoke as it sometimes gets smoky in my area...

I've never used nor sold Xiaomi units but here are some of my observations/opinions based on some online research and another commentator provided some feedback, as well. Xiaomi Mi Air Purifier 3C (7/1/24) Xiaomi - Not as good as the other options - Xiaomi Mi Air Purifier 3C is probably less expensive than all the other options and I think it can improve your environment… I just don’t know to what degree… Most all air purifiers will improve the environments they are put it to varying degrees… if desperate - I’d maybe check this one out… Xiaomi Smart Purifier 4 Compact (8/6/24) 10/2/24 - someone commented on my YT Channel: “I tested a one year old filter for Xiaomi air purifier 4, whose filters use "electrostatic charge". The old filter captured only about 10-20% of particles 0.3-1 micron size in a single pass through the filter, compared to a new one that captures close to 100% as advertised. Do real HEPA filters (that don't use electrostatic treatment) have degradation of filtering efficiency or they just have reduction in airflow?” ********************************************************** 1) Does not possess a HEPA filter. They call it a “High Efficiency Filter”. Off their website: “Xiaomi's filter uses melt-blown PP fibres with electrostatic technology. With greater space between fibres, larger volumes of air are able to pass through the filter.” So, their filter is more porous than a True HEPA filter and it therefore allows for more airflow. 2) Actual Air purifier and Filter were not tested for particle filtration. They say on their website, “the filter material used for this product achieved a filtration efficiency of 99.97% for 0.3μm particles.” This is sneaky - they are saying the filter material used for the filter was tested but the actual filter was not tested. It is always harder to make the actual filter perform at a good level than just the material itself. This is sneaky/deceptive marketing. 3) Carbon filter: The carbon filter is pathetic and just an afterthought and will barely help with odors, at all. 4) Gaskets on the filter: The filter does not possess a gasket on the top of it so it’s just plastic against plastic which = a terrible seal inside the air purifier. On 10/5/24 @RRR20238 said (this is in your big notes doc.): Thank you for the detailed reply! I thought about what you said and did some more testing. It turned out that the problem with the old filter was the restriction of the airflow, not the discharge of the electrostatic treatment, as I initially thought. Although it could play some role, but to a much lesser extent. However, the air flow restriction of the old filter caused reverse air suction from the outlet of the air purifier or/and seal leak. This dirty air then was mixing with the air going through the filter, hence bad air quality readings at the output of the purifier. I used IQAir AirVisual Pro air quality monitor for testing. The original idea was to repurpose the old filter and use it in a DIY Corsi-Rosenthal box style air purifier. It was in this case that I got only 20% reduction in 0.3-1 micron size particles by placing the Airvisual on top of the fan. In contrast with the new filter this setup showed that there's 0 µg/m3 of 0.3-1 micron size particles left according to the Airvisual, so close to 100% efficiency. It was this test that I wrote about in the original message. After reading your reply I thought that I should test the filters in the Xiaomi airpurifier itself, since using it in the DIY is not exactly a valid test, because that is not how it was supposed to be used by the manufacturer. In this case I got about 50% percent reduction in 0.3-1 micron size particles. However the new filter was also having trouble to reduce particles to 0 µg/m3, and the Airvisual's readings were bouncing in the range of 0-2 µg/m3 at the outlet of the purifier (down form 50-90 µg/m3 in the room, where I burned an aroma stick). So I thought there might be a seal leak, or/and the top of the air purifier, where the fan is, got contaminated with particular matter because of the old filter leaking, and was releasing particles now. I wiped inside of the top part of the purifier with a microfiber, got some dust on it. Then I blowed the fan with compressed air and saw a cloud of dust going out. So there was definitely particle contamination there. This cleaning indeed helped and the new filter finally got particle readings to 0 µg/m3. However the old filter was still at about 50%. Then I came up with the idea of placing the Airvisual directly inside the filter, since it is a barrel shaped filter. With this testing setup I was finally able to get 0 µg/m3 readings from the old filter. Only when I started burning an aroma stick near the intake holes of the air purifier while running it at the 3rd speed, did the reading deviate from 0 µg/m3. On 2nd speed the reading was 0. So my guess was that on speed 3 some air got into the filter through the exhaust outlet because of the reverse suction. With that in mind, I made a tube from paper and tape, and put it on top of my DIY. I measured the air quality inside of this tube and finally got 0 µg/m3 reading from the DIY with the old filter. As I write this message I did a quick test again: Ambient air the room: 10 µg/m3. Old filter without the tube: 8 µg/m3. Old filter with the tube: 0 µg/m3 (measured inside the tube). The new filter gives 0 µg/m3 regardless of the tube. From this I conclude that the problem with the old filter is the restriction of the airflow that causes reverse suction of the air. I guess it is better than having a filter that passes through most of the particulate matter because of loosing electrostatic charge. However it raises the question of the design of the air purifier itself, since reverse suction is obviously a problematic behavior. Those air purifier that have HEPA filters after fans, or those that have longer airways after fans might be better protected against this reverse suction as filters get saturated.

A CR Box on high speed, will filter larger particles well like we saw in the RTINGS.com Tests: kzbin.info/www/bejne/lZywd4immdaIrac&ab_channel=AirPurificationEducation But it won't help for VOCs/Chemicals and it won't filter the smaller more dangerous particles, as well as, an upper echelon HEPA solution. Thanks!👍

Yes, it kinda does, now that you mention it. An "Elite Particle Filtering Trash Can". Maybe they should incorporate that into their marketing campaigns, lol!😆

I analyzed some of the Fellowes offerings and here is what I currently think based on what I've seen... This was one of the brands (out of about 50) that we sold in my last company however, I didn’t consult on it much. Looking at some videos online: Video 1: Fellowes AeraMax Professional Air Purifiers with PureView kzbin.info/www/bejne/aIq4nWesfa2Hd9E&ab_channel=FellowesBrands Patented “PureView Technology” they say early in the video. I do like that the unit can be hung on the wall. The Filtered air comes out the top of the unit which may not be the best option as after we hang it on the wall - it is already up towards the ceiling of most rooms… so the clean air will be pushed up towards the ceiling rather than towards the room’s occupants. This will negate any chance of DPCA - Direct Path of Clean Air… for the occupants… and we’d 100% have to rely on “Air Exchanges” but there is really no such thing as 100% air exchanges in a room in the real world. That said, it may be able to do a good job of cleaning a room it is sized correctly for… or super sized. They are marketing the ability of the unit to take air quality samples from the air in the room and turn on based on poor air quality. But, I don’t want my air filtration solution to “turn on” when it senses poor air quality - I want my air quality to be be good all the time in my space - so I run my filtration solutions 247 on pretty high speeds. Why wait for the air quality to get worse? At :39 in the video they show the sensor reading “Particles Captured 99% PM2.5”. Now, I think PM 2.5 for most sensors means particles “down to PM2.5” - even though the official definition is “lower than 2.5”. And 2.5 micron sized particles would not be considered small, IMO… and they only comprise about 5% of all the particles in the air we breathe… so this is not an impressive particle measurement, IMO. At 1:02 it also talks about the ODOR/VOC levels and that the unit can provide us a reading on this. However, there can be over 15,000 different chemicals in the air we breathe and I have yet, to come across a sensor that can test for all of them so… I currently think this is just an OK feature. At 1:12 it shows the HEPA filter to be 2” in thickness and the carbon is only ⅜” so that is not a lot of carbon at all for VOCs/chemicals, etc. So, I would not consider this to be a great solution for odors… at least, not long term. At 1:17 they talk about the “PureView Technology” and it would appear this is just in regards to the sensor on the front of the unit. But, it does not appear that they have any specific special “filtration technology” besides a HEPA and carbon filter. The Product Page on their website states the following: www.fellowes.com/us/en/catalog/air-quality-management/array-networked-air-purifiers-monitoring/pg/wall-stand “Fellowes 3-stage filtration (pre-filter, carbon, and H13 True HEPA) effectively removes at least 99.95% of particles as small as 0.1 microns, including allergens, such as pollen, dust, pet dander, and smoke” These filtration numbers will also be contingent upon how well the filters are sealed inside the units. And perpendicular installed filters - like the ones in these units - are typically harder to create a strong seal for, inside the units. WARRANTY: 5 years sounds good. 18B) Array™ Wall AW2 Air Purifier The Array AW2 is $4,515.00 which is an INSANE amount of money for an air purifier. We could get 4 Airpura V714 units or 4 IQAir HealthPro Plus units for that amount of money. They seem to be selling the benefits of the data you collect from your air quality with the sensors on the units… which is not a selling point to me.. This expensive big unit gets 3 Air exchanges per hour in 1,000 sq. ft. with 8 ft. ceilings and a single Airpura V714 or a single IQAir HealthPro Plus will get at least that much in the same space but for about 75% less money. Wow! So, it can be put on the wall which is great and it provides data on some air quality measurements that I don’t currently feel is a great value add… We get 18 lbs. of carbon with the V714 which is WAY more than what the larger AW2 offers and we get a SuperHEPA filter that filters BETTER than HEPA… at 75% LESS of an investment. Plus, the seal on the Airpura units appear to be better, as well. Video2: Fellowes AeraMax | The Difference kzbin.info/www/bejne/aaKpfWSsi7moqrs&ab_channel=FellowesBrands At 1:45 = dirty air comes in the front of the unit… but it enters the front of the unit at the sides - not like they show in the video. At 2:05 it shows in the larger unit - there are 2 sets of HEPA/carbon/prefilters in the larger unit. And a fan behind each set of filters - so 2 fans. At 2:18 - they talk about proprietary, patented, technology - “EnviroSmart” but this is just in regards to the sensors NOT the filters involved in filtration. They just use similar filters like other companies. Also, again, I don’t want my air filtration solutions to “react to changes in my air quality” - I want good air quality all the time. At 2:31 they say the AeraMax Pro “senses occupants entering the space and immediately works to increase the air exchange rates…” OK, so you are breathing dirtier air when you enter the room… THAT is not a good thing, lol! “Then as people leave - it shifts to standby mode to conserve energy and extend filter life.” I run my air purifiers 247 in my spaces at high rates of speed - as that will improve my air quality the most. It seems all their units can be placed on the wall or put on a stand on the ground and I do like this flexibility, for sure… (CONTINUED BELOW)

Video3: Fellowes AeraMax Professional AMIIIS Demonstration (older video from around 2015) AirMax Pro AM3S kzbin.info/www/bejne/jJzCdYmiiN5oo5o&ab_channel=FellowesBrands At 1:09 - it says the units have BiPolar Ionizers - which I would not want turned on. At 3:44 she shows the 3 filters get placed into a plastic frame (The Filter Cage) before they go into the machine but I don’t see any gaskets around the HEPA filter so some dirty air will escape around it. There is not a good, tight seal inside the plastic frame. At 4:00 she shows the carbon filter and it doesn’t look any more impressive than a $150 Winix 5500 carbon filter. That thing is NOT going do a great job on VOCs/Chemicals/Odors. At 5:14 she shows they have a much larger 2” carbon filter (7 lbs. of coconut shell carbon) if you are dealing with a lot of odors however, there isn’t a HEPA filter involved in this option… so some carbon will get into the air and this option will not provide good particle filtration, at all. At 5:37 she shows a Hybrid filter - 12 month changeout- it has 1” of carbon and 1” of HEPA… Video4: How To Change Your Filter | Fellowes AeraMax® Pro AM4 kzbin.info/www/bejne/b6C0qZaQrbKGsMU&ab_channel=FellowesBrands At 1:27 they say the Prefilter and Carbon filters get replaced every 6 months and the HEPA filter gets replaced every 12 months. According to their website: www.fellowes.com/us/en/catalog/air-quality-management/filters-and-accessories/listing/air-purifiers-commercial-filters These filter replacements will be pretty expensive. PRO2 Carbon filters with Prefilter will be $400 for 2 of them. And this is the option that does not allow for a HEPA filter. PRO2 True HEPA Filer (2 pack) will be $419.00 ⅜” carbon filter with prefilter will be $250 for 4 of them which I think are supposed to last a year… so that would be $419 + $250 = $669 in filter replacements for the larger unit per year… that is SUPER EXPENSIVE and the most expensive residential filtration filter replacement option I think I have ever seen. WOW! They are literally “Printing Money” lol! At 2:53 they open one of the units and at 2:55 there looks like there may be a gasket on the back of the Filter Cage but I am not sure. At 3:44 they show some velcro on the 4 corners of the Carbon filter to help the Prefilter stay in place - which is good. It is hard for me to see if there are gaskets involved with the filters and it is hard for me to determine how good the seal is inside the unit. That said, perpendicular installed filters will definitely tend to leak dirty air more than well sealed cylindrical shaped air purifiers and units like the IQAir HPP or Aeris 3 in1 - that install the filters parallel to the ground. CONCLUSION: So, I currently think these Aeramax units will probably reside in the upper part of the 2nd echelon of air filtration solutions for particle filtration… But they will be below the upper echelon solutions… as they will not provide elite particle filtration. They should improve the air quality in a correctly sized space, for sure - as most all air purifiers will improve air quality in the spaces they reside in… to varying degrees… On the Carbon issue… I think they are just average solutions, at best, for VOC/odor removal with the regular carbon filters that come with the units. They should do a much better job on VOCs/odors with the larger carbon filters but we sacrifice most ALL particle filtration benefits with that option - so, for me - that would almost never be an option. And they also sell hybrid filters which are ½ carbon and ½ HEPA and I currently think, they would probably be the best “all around” option for their solutions. All that said, for the kind of money they are asking for folks to invest in their solutions… on the largest unit… we can get ELITE Particle Filtration with the Airpura V714 which will provide MORE air exchanges… for 75% less of an investment for the initial hardware and it is also much less expensive on the cost of ownership issues, as well, for filter replacements….. Or we could get 2 smaller Airpura V414 units and put them at 2 different locations in a space, as well, and get much better air filtration… I don’t care about the “Smart” features on air puriifers and Fellowes really tries to market this aspect of their solutions. I want elite filtration solutions - I don’t value data and graphs on middle tier filtration results.

@@AirPurificationEducation thank you for the detailed reply. May God bless your labor. I’m going to look into the AirPura line. Thanks!

@ thank you!

Thank you for your feedback. The problem with this is that folks on YT doing "testing" are utilizing amateur testing equipment and methodologies so their results are not reliable. These 2 videos will explain: "Can You TRUST Air Purifier Tests On KZbin?" kzbin.info/www/bejne/mJbIhGmYnsmfack&ab_channel=AirPurificationEducation "Air Purification Tests - This is Who I Trust!": kzbin.info/www/bejne/gnO8k4ZnaJlmr5o&ab_channel=AirPurificationEducation

@@AirPurificationEducation you bring up a good point. I just got the air doctor 3500. Sprayed a solvent with a heavy perfume spray right next to it and the air quality did NOT change. Stayed “blue”. It 100% should have. It stinks in the room now. I’m seriously thinking about sending these back. How disappointing!

@@OrthodoxChristian27 The air quality testers/monitors can be pretty unreliable, in general, whether you buy them as handheld units... and esp. the less expensive ones on the air purifiers themselves... unfortunately.

@@AirPurificationEducation I feel like I’ve been duped. I’m sending these back, I have 30 days. Thanks for your education. 👍 The air quality changed when a bunch of dust was airborne, but seems to do nothing for chemicals/odors, etc. Any idea why that might be?

@@OrthodoxChristian27 There can be over 15,000 different chemicals in the air we breathe so no single monitor/tester can read them all and it is harder for monitors to test for chemicals in the air than it is to test for particulates. I was in a hotel lobby last year that had horrible VOCs/chemicals and I had a Temtop and an ATMO air quality testers and they BOTH said the air quality was "Good", LOL! No, it was HORRIBLE... so, I simply do not trust them.

No, unfortunately, I am not familiar with how inhalers work. I used one several years ago... but eventually stopped I am happy to say.

Thank you for your question. I have had some feedback on some of the Xiaomi units and I looked at them a little in the past and put some notes in a document. ***************************************************************************************** 47.A. Xiaomi Mi Air Purifier 3C (7/1/24) Xiaomi - Not as good as the other options - Xiaomi Mi Air Purifier 3C is probably less expensive than all the other options and I think it can improve your environment… I just don’t know to what degree… Most all air purifiers will improve the environments they are put it to varying degrees… if desperate - I’d maybe check this one out… 47.B. Xiaomi Smart Purifier 4 Compact (8/6/24) 10/2/24 - someone commented on my YT Channel: “I tested a one year old filter for Xiaomi air purifier 4, whose filters use "electrostatic charge". The old filter captured only about 10-20% of particles 0.3-1 micron size in a single pass through the filter, compared to a new one that captures close to 100% as advertised. Do real HEPA filters (that don't use electrostatic treatment) have degradation of filtering efficiency or they just have reduction in airflow?” ********************************************************** 1) Does not possess a HEPA filter. They call it a “High Efficiency Filter”. Off their website: “Xiaomi's filter uses melt-blown PP fibres with electrostatic technology. With greater space between fibres, larger volumes of air are able to pass through the filter.” So, their filter is more porous than a True HEPA filter and it therefore allows for more airflow. 2) Actual Air purifier and Filter were not tested for particle filtration. They say on their website, “the filter material used for this product achieved a filtration efficiency of 99.97% for 0.3μm particles.” This is sneaky - they are saying the filter material used for the filter was tested but the actual filter was not tested. It is always harder to make the actual filter perform at a good level than just the material itself. This is sneaky/deceptive marketing. 3) Carbon filter: The carbon filter is pathetic and just an afterthought and will barely help with odors, at all. 4) Gaskets on the filter: The filter does not possess a gasket on the top of it so it’s just plastic against plastic which = a terrible seal inside the air purifier. On 10/5/24 @RRR20238 said (this is in your big notes doc.): Thank you for the detailed reply! I thought about what you said and did some more testing. It turned out that the problem with the old filter was the restriction of the airflow, not the discharge of the electrostatic treatment, as I initially thought. Although it could play some role, but to a much lesser extent. However, the air flow restriction of the old filter caused reverse air suction from the outlet of the air purifier or/and seal leak. This dirty air then was mixing with the air going through the filter, hence bad air quality readings at the output of the purifier. I used IQAir AirVisual Pro air quality monitor for testing. The original idea was to repurpose the old filter and use it in a DIY Corsi-Rosenthal box style air purifier. It was in this case that I got only 20% reduction in 0.3-1 micron size particles by placing the Airvisual on top of the fan. In contrast with the new filter this setup showed that there's 0 µg/m3 of 0.3-1 micron size particles left according to the Airvisual, so close to 100% efficiency. It was this test that I wrote about in the original message. After reading your reply I thought that I should test the filters in the Xiaomi airpurifier itself, since using it in the DIY is not exactly a valid test, because that is not how it was supposed to be used by the manufacturer. In this case I got about 50% percent reduction in 0.3-1 micron size particles. However the new filter was also having trouble to reduce particles to 0 µg/m3, and the Airvisual's readings were bouncing in the range of 0-2 µg/m3 at the outlet of the purifier (down form 50-90 µg/m3 in the room, where I burned an aroma stick). So I thought there might be a seal leak, or/and the top of the air purifier, where the fan is, got contaminated with particular matter because of the old filter leaking, and was releasing particles now. I wiped inside of the top part of the purifier with a microfiber, got some dust on it. Then I blowed the fan with compressed air and saw a cloud of dust going out. So there was definitely particle contamination there. This cleaning indeed helped and the new filter finally got particle readings to 0 µg/m3. However the old filter was still at about 50%. Then I came up with the idea of placing the Airvisual directly inside the filter, since it is a barrel shaped filter. With this testing setup I was finally able to get 0 µg/m3 readings from the old filter. Only when I started burning an aroma stick near the intake holes of the air purifier while running it at the 3rd speed, did the reading deviate from 0 µg/m3. On 2nd speed the reading was 0. So my guess was that on speed 3 some air got into the filter through the exhaust outlet because of the reverse suction. With that in mind, I made a tube from paper and tape, and put it on top of my DIY. I measured the air quality inside of this tube and finally got 0 µg/m3 reading from the DIY with the old filter. As I write this message I did a quick test again: Ambient air the room: 10 µg/m3. Old filter without the tube: 8 µg/m3. Old filter with the tube: 0 µg/m3 (measured inside the tube). The new filter gives 0 µg/m3 regardless of the tube. From this I conclude that the problem with the old filter is the restriction of the airflow that causes reverse suction of the air. I guess it is better than having a filter that passes through most of the particulate matter because of loosing electrostatic charge. However it raises the question of the design of the air purifier itself, since reverse suction is obviously a problematic behavior. Those air purifier that have HEPA filters after fans, or those that have longer airways after fans might be better protected against this reverse suction as filters get saturated. To be fair the Xiaomi air purifier's screen recently started to indicate that I need to change the filter. However I think that the reverse suction of the dirty air through the exhaust outlet might have been going for a while before the filter replacement indicator lit up.

@@AirPurificationEducation Do you think the claims on the Ultra version is realistic enough? It said the filters total weiht is 7KG, and to ship it the package weights 24KG

@@koreankorean5645 You mean the "Xiaomi MIJIA All-Effect Air Purifier Ultra Enhanced Edition"? As I am not seeing much info. on this unit... I'm in the US... maybe you are outside the US? Here is some info. from a Chinese website: www.gizmochina.com/2024/07/07/xiaomi-launch-mijia-air-purifier-enhanced-edition/ if that's the one you are speaking about.... I'd have to see some videos and reviews on it to analyze it.

Thank you for your feedback - I appreciate it! 👍

Yes, if you only have 110 sq. ft. then I think it will probably be a good option for you for particles. It is not strong for VOCs/chemicals/odors. Here is what I emailed someone else a few months ago after looking at it online for a while. They had a larger space than 110 sq. ft. ****************************************************************************************************************************** EDIT: 1/23/25 The pricing dropped significantly on the IT to $345 without carbon and $360 with carbon. A: 7/23/24 Yeah, I saw that yesterday but I don’t plan on doing a review with the physical product for a while - if I ever get it in my possession. I have owned 3 Austin Air units for over 15 years - 2 of the big ones/Standard HM400 and the Jr. unit, as well. So, here are my initial knee-jerk opinions/analysis of the IT based on what I see online. 1. Size: The unit is 8” tall and 11” x 11” which seems like a pretty decent size. 2. Personal Air Purifier: They call it a “personal air purifier” but that insinuates that the unit would blow air on you/your face region. And with the Austin units - the air exits the units at about a 45 degree angle (or more) - shooting upward. So, if you want to have the air blow right in your face region with the IT - then you would have to be very specific where you place the unit to benefit from the airflow and it would have to be very close to you and kinda “under” your face region… which does not sound ideal. I think they should have put moveable louvers on the unit so people could direct the air flow more easily. Airflow of the unit: The CFM is as follows. 125 high, 62.5 medium, 31.25 low. It gets a lot of airflow for such a small unit and could get 4.6 air exchanges in a 200 sq. ft. room with 8 ft. ceilings - on high speed. So, I’d say it could be more than a “personal/spot” air purifier in a room of 200 sq. ft. or less. 3. Carbon for VOCs/Odors/Chemicals: The unit offers 2 different options - it can come with just a HEPA filter and prefilter or with an upgraded carbon cloth filter. However, there is only a $15 difference between the 2 versions. How much carbon do we think we are getting for $15? Not a lot, I am sure, as good quality carbon is fairly expensive. Plus, they do not provide a warranty for the carbon filter. Their website states, “*The optional VOC Carbon Wrap add-on is designed to last three months under normal conditions. The carbon VOC Wrap does not carry a warranty.” So, the carbon component only lasts 3 months “under normal conditions”. Based on what I am seeing - they don’t seem to have much confidence in the carbon solution, IMO… and neither do I. So, I would look at the unit as more of a particle filter solution only. The carbon option does not appear to be very strong. Also, the carbon solution is $15 by itself and it would probably need to be changed about 4 times a year… So, that cost may add up over time, as well, with shipping, etc. 4. Pricing: The HEPA only option is $475 and the option with carbon is $490. I mean, wow… that is expensive for what we are getting when we compare it to two other options which I think are superior - the IQAir Atem Desk unit and the Airpura R414. 4A. The IQAir Atem Desk unit is $400 and it filters ultrafine particles at an elite level. It does not come with carbon but you can get a Plus filter which has some. However, I don’t think the carbon will last a long time. That said, we can more easily direct the airflow to our face region and it is high level filtered air for particles, for sure… for 18% less money than the IT. Plus, it is a narrow unit so it will fit more easily on a desk. All that said, I view the Atem Desk as a "spot" air purfier - to your face region - as opposed to a soltuion that will provide air exchanges as it only has 39 CFM on high speed. 4B. The Airpura R414 is 7.5” taller than the IT and 1” wider - so it is a larger unit. It is not officially categorized as a “personal air purifier” but it is still something that can fit on a desk next to a person and I think its going to be able to blow purified air in the face region much easier than the IT. Because the air comes out on all sides at about face level (depending on how one is seated). So, I personally categorize the R414 as a quasi personal air purifier AND a room air purifier that can actually provide a good amount of air exchanges. And for $44 more than the IT we get a Super HEPA filter that filters better than HEPA at 99.99% at .3 microns. So we get BETTER than HEPA filtration. And we get 8 lbs. of carbon which is vastly superior to both the IT and the Atem for VOCs/Odors/Chemicals. Plus, it has 353 CFM on the free flow side - which will come to about 250 CFM on high speed with the filters installed. So the R414 can provide almost 4.5 air exchanges per hour, in a 400 sq. ft. room, as well. Again, with a Super HEPA filter = better than HEPA filtration. Airpura also has an R400 unit with the same dimensions as the R414 but it comes with a HEPA filter for $500. Which is only $10 more than the IT. So, when I initially look at the numbers and features of the 3 units - I personally, would probably go with either the Atem or the R414/R400 at this point in time. That is my initial knee jerk reaction. I currently believe that Austin tried to “follow” Airpura as Airpura came out with smaller units about a year or so ago - and their smaller units like the R414/R400 are selling very well. So, I feel as though Austin tried to kinda copy them in this regard - as the two brands are oftentimes compared to each other. I hope that helps.👍

@@AirPurificationEducation Well, I sure know where to get my info from! I appreciate the response and the email copy. I looked at the units and they are quite nice. The good ones are not in my price range and to explain why is irrelevant. Moreover, my place is very small; about 768 sq ft total, which includes 2 small rooms and 1.5 small baths. I use one of the small bedrooms as an office, which I don’t use much, but I have cats and that is where their stuff is, but they hang out wherever I am. I’m more concerned about the living/kitchen combo area where we hang out, and at night in my small bedroom, which believe it or not, is only 10’ x 11’. The units you advised are too expensive for me and the Air IT I mentioned would be a hardship to buy, but I would do it if I would help one of my cats. It appears it is made for a “regular” sized room (like in a house), not one you’d find in a manufactured home as I have. However, you pointed out the con that makes the decision about the IT and it is the air flow. I don’t use my ceiling fan at night (nor much at all), so the air would definitely bother me and is a deal-breaker regardless of price. Your idea of diverters would be great. The “trash can” looking Hometics Pet35 I’m using blows straight up, so it can be closer to me without being bothersome and I can just move it from the living area to the bedroom, but I’d just rather not. Even though I live in Florida, I don’t like the feel of wind on my skin indoors this time of year, and never on my face (I’d wake up congested). Of course if it was hot, that wouldn’t apply (except the face - that’s a never), but just in general I don’t prefer feeling a breeze indoors; love it outside though. I couldn’t find the Airpura R414, but did find an R400 at $500, but is a good deal more than $10 away the Air IT I looked at. As a reminder, I would buy an open box and currently those are selling for $313. That $187 difference is very significant to me as I didn’t even want to spend $187 on a unit (it’s not that I don’t want to, I just can’t). No one but you would read this far and on my fixed budget, I only have about $400 over my expenses each month, and that does not cover gas, food, or anything but mandatory bills. So buying anything over $100 is a massive expense for me. It’s not that I can’t do it, but I have to give something else up in exchange. I’m already down to one meal a day, so if I cut that out, I won’t need a purifier…lol. I have to feed my cats also, and would have gone crazy nutts without them during the pandemic, but they are older, not adoptable because of their age, and that they all grew up together and I can’t separate them after 10 years. That explanation is for anyone who did happen to read this far and say, “You could save money if you got rid of your cats”. It’s not that I haven’t thought of it, but the last part of my stone heart could not do that and it would strip me of the last part of humanity I have left. But now, back to you and the filtration. I appreciate all the info and would use it to buy a quality unit if I could. These “homes” are not as cheap as people think, and there is always upkeep and repairs to be made. Currently, I’m missing 24 roof panels from hurricane Milton. The estimate to repair was less than my insurance payout, so guess what? Yep, I’m a roofer now. I didn’t have the $7500 to pay someone else to do it, so I crunched and bought $1700 in supplies and up on the roof I go. Replaced the capacitor on my A/C last month for $12 that a technician wanted $400 for. That how I live and how it has to be, for now anyway. $500 a week used to sound doable; not so much now. Too bad I can’t make my own air purifier that didn’t look like 4 filters and a box fan! Thanks again for your reply and great information! I'll find something cheap enough. It might not be HEPA, but as you said about Levoit (which I'm not buying on principle), "it's better than nothing".

That is crazy... it is kinda nuts how far the wildfire smoke can travel. Thanks! 👍

@AirPurificationEducation it's also nuts the sheer size of Australia's bush fires. 46million acres was burnt compared to US biggest of 17 million. It also omited 430 million tonnes of C02. Australia's forrest fires are ferocious

Here is what I think of the Shark NeverChange air purifier - I've looked at it a few times online over the past several months.. UPDATE: 1/23/25 I watched this video review on it by Consumer Analysis: kzbin.info/www/bejne/iHTPY4KlgderZ5I&ab_channel=ConsumerAnalysis 1) PREFILTERS: The screen prefilters seem to be good. It also has a blue prefitler that wraps around the HEPA filter, as well - which is good. However, it does not appear to be able to be detached from the Carbon/HEPA filter so you can vacuum it - so that is not ideal. 2) GASKET: at 20 seconds in - We can see a gasket at the top of the filter and it looks OK. It does not appear to be of high quality but decent. There is a groove in it which is good, I think. 3) at 5:49 they show an Odor Neutralizer component… which does not seem like a good idea. He says it created a smell to the room - which is not a good thing, in general. I also watched this video from Just a Dad Videos: kzbin.info/www/bejne/jJ3ShXaFoMaqfZo&ab_channel=JustADadVideos 1) INTERNAL SEAL: At 33 seconds he shows how the unit is closed and it is similar to the Levoit units and other lower end cylindrical air purifiers… where there will not be a good seal inside the unit between the filter and the inside of the unit. 2) At 1:18 we see there is barely any carbon at all - a super low amount of carbon so this solution is NOT going to be good for Chemicals/VOCs or odors, at all. 3) At 2:00 he shows the Fragrance component - it is some type of gel that the air blows across… I do not like this part. I think they added it to try to mask odors in the environment since they barely have any carbon…. NOT a good strategy, IMO. 4) WARRANTY: The manual says it has a 2 Year Warranty which I think is decent for this type of air purifier and price. 5) Pet Particle Barrier - around the HEPA filter: at 1:17 he shows the exterior of the box with the different filters - and the Pet Particle Barrier filter goes around the Activated Carbon part but it is part of the whole filter and I don’t think it comes off for you to vacuum it… so this is not ideal. It is affixed to the HEPA/Carbon Filter. 6) At 1:17 the box also says 99.98% at .1 to .2 microns but that is NOT going to happen with this unit, LOL! 7) CONCLUSION: I think it is a decent air purifier for particle filtration - probably middle part of the 2nd tier group. And it will help improve the quality of air for particle filtration. But the filter is probably not going to do a good job for 5 years. It will probably need to be changed before that time. And the seal inside isn’t good so it is not an elite filtering solution. It is a terrible option for odors/VOCs as it will not help for this - barely at all. Other Options in the same price range - or in this case a little less expensive: I like the TruSens Z-3000 for up to 400 Sq. ft. rooms - this has good particle filtration and a better seal inside the unit. It has a better seal between the HEPA filter and the inside of the unit but there is barely any carbon in this solution, as well… so it is poor for VOC/Chemical/Odor Filtration. UPDATE: @ November 2024 - I got a hold of one of these at Costco that was out of the box and it was not impressively made. It felt cheaply made. @May 1st 2024 1) I've briefly checked out some of the Shark purifiers recently at someone's request... but I would currently just consider them "also rans", at best... - def. not elite. They are trying to sell on "saving money" by not changing your filter... "The Shark NeverChange Air Purifier MAX"... I see this as just a marketing ploy to try to differentiate themselves in a very competitive market. 2) And this blurb, "Purify extra-large areas-up to 1400 sq. ft. in just one hour ^. Perfect for multiple rooms, large bedrooms and living rooms, basements, and more." - screams of not really caring about your customers... as they are basically touting a possible single air exchange in 1400 sq. ft. per hour which is honestly, ridiculous... As most everyone knows - you really want at least 3 air exchanges - even better 4 or 5 per hour with your solution... So, they are being "marketing Smart/Savvy" with their cost saving concept and supposed large square footage coverage ability of the solution - but in reality - it is not a good thing, at all, IMO. 3) The few videos I've seen on their site show people wiping off a dirty screen filter from the unit like they're the only purifier that has this filter screen. Odd but maybe they feel they can market it this way to sell it to their vacuum customer base. 4) "NEVERCHANGE FILTRATION: HEPA filtration that won’t need replacement+. Debris Defense filter protects HEPA layers, for up to 5 years" ---Great... the NeverChange filter that gets changed EVERY 5 years... Ya just can't make this stuff up. I'd be embarrassed to push this product with these kinds of marketing tactics. 5) It says, " A HEPA filter captures 99.98% of particles." When in reality HEPA is 99.97% at .3 microns... so it seems like they are indirectly saying they perform better then HEPA... which may impress some consumers who are not really knowledgeable about air purifiers. 6) I think they have made vacuums and some other things for many years and decided to enter the air purifier market, as well, and the heads of some of their departments decided their “air purifier offering”: 1) The unit must look different than most units on the market - must look unique. 2) We need to differentiate our offering = "NEVERCHANGE" filtration which they apparently trademarked.... so you'll save more money with our solution. "Shark NeverChange Air Purifier MAX, saves you $300 or more in filter replacement costs over 5 years*." 3) It can cover 1/2 your house all by itself. ***but they do not seem very interested in talking about how well the solution filters... which is pretty interesting. ***Also, they have many asterisks after many of their claims on the product page, but I don't see the additional information at the bottom of the page like most all other websites... I am losing more and more respect for the Shark brand the more I analyze their new purifiers on their website These guys just want to sell product regardless of how much it actually improves air quality, IMO.

I am sorry to hear about your issues. Unfortunately, air quality testers/monitors will not provide measurements of Cigarette/smoke/week. You can get an air quality tester/test to provide levels of formaldehyde but unfortunately I do not know of the best one out there. I focus on air purifiers mostly. Sorry I can't help more.🙁

@@AirPurificationEducation at least you've given me some info...It smells like a skunk has been in my home..I'm sure it isn't medical grade(weed) as I have never smell anything so gross ...I don't know what I have inhailed all I know is it's making my resting heart rate 170 at times and my blood pressure is up. .Again thank you for at least reading.

Thank you for your question - it is a good one! Here is a comparison: 1) The IQAir HealthPro Plus: **I have an IQAir HPP in my home and used to run one in an office in the past - for 10 years. **This is a very good filtering solution for particles. However, it only has 5 lbs. of carbon and it is not great for long term VOC/chemical/odor filtration. **AIRFLOW: The IQAir HPP has 300 CFM (airflow) but the Airpura V714 has about 440 CFM or 32% more. **And 2 Airpura V414 solutions possess 500 CFM total - so, we would get 40% more CFM and airflow with the 2 Airpura units than an IQAir HPP. In larger spaces it will be better to have 2 smaller units at 2 different locations in the space, IMO. **CARBON: The IQAir HPP only has 5 lbs. of carbon but the V714 has 18 lbs. or 72% more. **We would get 69% more carbon with the 2 Airpura units (8 lbs. of carbon in each of them) instead of a single IQAir HealthPro Plus solution. And if we have a 500 sq. ft. room or smaller we could go with 1 V414 which has 8 lbs. of carbon but still 37% more carbon than the IQAir HPP. **The IQAir HealthPro Plus does not come with a cleanable prefilter and the airflow will decrease more over time without it. You can get the cleanable prefilter for the unit for $140. I have recently measured a 7-9% decrease in airflow on my IQAir HPP unit every 35 or so days... but I don't have a prefilter and I am sure the prefilter will keep the airflow at a higher rate over time. **So, a single IQAir HealthPro Plus would be about $949... and about $1,089 with the prefilter. **Airpura V714 retails for $1,050 and would be $945 with the 10% Coupon Code DZAIR10 ** 2 Airpura V414 units would be $1,170 and $1,053 with the Coupon code... or for a room of 500 sq. ft. or less - we would only need 1 V414 = $527 with the code. 2) IQAir GC: **The GC is very good for filtering odors/VOCs/chemicals but it does not filter particles as well as the HealthPro Plus or the Airpura V714 or the smaller V414 (the V714 and V414 have SuperHEPA filters which filter better than HEPA while the GC does not even filter at a HEPA level). **CARBON: The GC has 12 lbs. of carbon which is 58% more than the IQAir HPP and 25% less than 2 Airpura V414 units and 33% less than the V714. **AIRFLOW: The GC has 300 CFM on max power which is the same as the IQAir HPP but 40% less airflow than 2 Airpura V414 units and 32% less than the V714. **Also, the GC will have the same airflow issue as the IQAir HPP if you do not purchase the prefilter for it. **The GC costs about $1,350 so it is 30% more than the HPP. And it is 22% more than 2 Airpura V414 units and it is 27% more expensive than the V714. **So, 2 smaller Airpura V414 units cost 22% less than the GC... but provide 40% more airflow and 25% more carbon + they filter BETTER than HEPA while the GC doesn't even filter at a HEPA level. **And the larger V714 costs 27% Less than the GC, but it has 32% more airflow, 33% more carbon and it filters better than HEPA while the GC doesn’t even filter at a HEPA level. **So, what functionality do the 2 IQAir units possess which the 2 Airpura options don’t? The IQAir units have timers and electronics which tell us when to replace our filters but the units don’t actually know how dirty the filters are - they just base the replacement intervals on time and speed. So, we are getting some electronics - but not SMART functionality that can be controlled by a phone. Just some electronics and timer options. So, I currently believe these 2 Airpura options are superior to the 2 IQAir options for Wildfire smoke. Please let me know if you have any additional questions. 👍

Hmmm... Looks like Airpura has a $50 discount for "the areas affected by wildfires". Thank you for the question👍

Thank you for your feedback. Yeah, there are just TONS of misleading ads and deceptive marketing practices in the air purification industry. After Levoit got busted by the BBB about 18 months ago - they had about 4 units on their website that they didn't market as having HEPA filters... (about 4 out of 24). But, last I checked about 8 weeks ago - they fully had about 20-22 out of 24 units on the website that they were not marketing as having HEPA filters in them... so about 90%! LOL! Come on, Man! That's Garbage! So, now on Amazon they list some of their units like this: " Our filter has strong filtration performance of ultra-fine particles. 99.97% filtration efficiency for 0.1 to 0.3μm airborne particulates, including pollen, dust, and animal dander allergens. Tested by an independent lab." But Ultrafine particles are .1 to .003 microns in size. NOT .1 to .3 microns... and UFP = 90% of the particles in the air we breathe and they are the most dangerous to humans... so, Levoit AGAIN is just messing around with their marketing... it really irritates me, lol! 😆 Thanks 4 the comment!👍

Appreciate it - thanks 4 the feedback!👍

Thank you for your feedback - appreciate it!👍
