Simply amazing video. Not sure what to say, but we are truly blessed to have an actual industry expert sharing your knowledge. Thanks for the hard work, looking forward to future content.

[@AirPurificationEducation]

Thank you for your kind words. I consider myself to be a "consultant" and "student" of the industry but don't currently think there are any "experts" in this field as there are simply too many solutions on the market and too many "sub niches" that fall under the "Air Quality" umbrella. And we are just beginning to learn about some of the negative long term health effects from exposure to ultrafine particles and some VOCs/chemicals. Lots to learn for sure - thank you!👍

Hello, what is your recommendations for airfilters can filter out Formaldehyde, Dibutyl Phthalate, or DBP, Toluene/Benzene? I need it for a nail salon.

[@AirPurificationEducation]

Hello Hung and thank you for your inquiry. You will want a lot of carbon to absorb the VOCs/chemicals. For a Nail Salon with those chemicals, I'd go with the Airpura C600DLX. It has 26 pounds of specialized carbon which is the most of any stand alone air purification solution I am familiar with. I consider Airpura to be the closest thing to "carbon experts" out of about 50 or so different air purification manufacturers that I work with.

In your air quality video you talk about the way that the HEPA designation is used loosely in marketing materials, that the term doesn’t necessary mean the filter follows any rigid or scientific standards of filtration, and that they are ineffective at trapping the most harmful particles, etc. If this is true, then the decision to discontinue use of the term doesn’t seem as malicious as this makes it out to be?

[@AirPurificationEducation]

Thanks for your question. Ohhh... this brings up a lot of stuff, lol... let's see... A)"In your air quality video you talk about the way that the HEPA designation is used loosely in marketing materials, " Yes, agreed. Most manufacturers take great liberties with the word "HEPA". B) "that the term doesn’t necessary mean the filter follows any rigid or scientific standards of filtration" Kinda. The term is supposed to have black and white standardizations/specifications. But many manufacturers twist some of the verbiage. The less than scrupulous manufacturers have a field day with it, LOL. But there are some really good manufacturers out there like IQAir, Austin Air, Airpura... and these companies really do try to make great solutions to help consumers. And they use quality HEPA materials and manufacturing processes to make their filters. C) "and that they are ineffective at trapping the most harmful particles, etc." Kinda... Ultrafine particles are the most dangerous to humans in the long term it seems - according to recent research... so the effects of UF particles may be more of an accumulative effect over time - is the way I'm currently viewing it... vs. larger particles that may give us more immediate discomfort like sneezing or coughing... and cause us immediate discomfort/noticeable issues. This is where things get kinda tricky... As, an expensive, well made True HEPA filter - like say the one on the ISS - International Space Station... is actually supposed to filter "BETTER than HEPA" with the smaller ultrafine particles - According to some testing that was performed on that filter. The problem is - MANY manufacturers take the results from that particular test and run with them and say, "Well, we also have a HEPA filter and therefore our filter does a better job on UF Particles, as well - just like the filter tested in the ISS." And that is where we have to stop and think for a second... NO! A $27 dollar "HEPA" filter made in China most assuredly does NOT filter, as well as, or in the same manner as the HEPA filters in the ISS. Let's be real. So, a really good True HEPA filter is supposed to actually do a better job on UF particles but I am confident we won't see that being true for over 99% of the filters in the Consumer Market. Maybe the Camfil HEPA filters ($200 each with steel housings and incidentally they've made HEPA filters for the ISS)... And maybe the Aeris 3 in 1 and Medical units... are the only ones that I can think of off the top of my head - who's 3rd party testing documentation shows/proves this... Not even the great IQAir has these results with the HPP - I think. So it is a SHORT list in the consumer market, for sure. So some of the upper echelon manufactures do have 3rd party testing and they do hit certain levels of filtration - like they advertise. And if they don't have 3rd party testing certifications - they will still utilize a higher level of quality of materials to make their "HEPA" filters. And they utilize good quality control in their manufacturing processes... In short, they really try... And they are proud of the solutions they create for the market/consumers. They make air purifiers to "Improve the Health of their Customers". That is their main goal. And yes, they have to make money doing this, as well. Unfortunately, many of the manufactures out there, IMO... Absolutely do NOT care as to whether or not their air purifiers improve the health of their customers -they just care about "selling product" and they'll stress "Air Quality Sensors" - Smart Apps. etc... Their solutions will typically be of less quality and will not improve the overall health of their customers nearly as much as the first group. BOTH Groups will say "HEPA" this and that in their marketing and advertising campaigns... and neither group will typically actually hit HEPA levels of filtration in the real world... BUT, the first group will be MUCH CLOSER to hitting the HEPA levels of filtration and therefore, they provide MUCH better solutions than the "just for profit" group. For ex. I just got an email from a guy who told me he was on a phone call with Helder from Airpura for an ENTIRE HOUR this past week - as Helder figured out the best carbon solution for his "Airport Jet Fuel" VOC/chemical issue. What he didn't know was Helder is the Founder and Owner of Airpura... THAT is how much they care about helping their customers. They guy didn't even know who Helder was. One of their sales reps. was out so Helder was helping with some phone calls. He is one of the top Carbon experts in all of North America, IMO. The sales rep. who was out has 16 years of industry experience with a focus on carbon solutions. These "also ran" companies don't have folks like this in their staff. At least, not on the front lines. D) "If this is true, then the decision to discontinue use of the term doesn’t seem as malicious as this makes it out to be?" 1) Hmmm, I don't currently see it that way. "True HEPA" performance is a filtration solution hitting 99.97% or better at .3 microns. That is a standardization in the industry. That definition is VERY RIGID and exact. 2) That said, over 99% of the air purifiers on the market don't actually filter at a HEPA level but still say "HEPA" on their marketing/commercials because the industry is not closely regulated. And it would cost a lot of money to really test each and every unit to know for sure... and test them 3-6 months in the future, as well, after some good "real world use"... which would provide "real world" results, IMO. But, make no mistake about it, "True HEPA" is absolutely defined as "99.97% filtration at .3 microns." And good/well meaning manufacturers will honestly try to make air purifiers that hit these numbers. 3) Now, some Air purifier manufacturers will have the FILTERS 3rd party tested and they will oftentimes get a "certification" stating that they perform at a HEPA level under certain circumstances (like different CFM settings). But they oftentimes do get the individual filters, 3rd party tested, at least. Or use a certain level of quality of HEPA material. 4) However, how the filter performs independently of being placed inside the air purifier is NOT the same thing as the "Total System" performance of the filter in the unit and them both being tested for their effectiveness simultaneously. Over 99% of the air purifiers on the market do not have good enough seals between the filter and the inside of the unit to prevent dirty air from escaping around the filters so even if they have good HEPA filters in them... they still don't perform at a True HEPA level as a "Total System." And... HEPA filters will tend to perform better at lower CFMs - the more air you push through them - the worse they tend to filter, in general. Of note: IQAir has their units tested with the filters in them and they provide "Total System" 3rd party filtration numbers. THIS is the way it should be, IMO. (CONTINUED BELOW)

[@AirPurificationEducation]

5) So, most air purifier manufacturers at least have HEPA filters in them (of varying quality) - and many were 3rd party tested to verify this. Yes, rigged and fake 3rd party testing is a very real problem but that is for another video... However, Levoit has made MILLIONS of dollars by marketing their air purifiers as having "True HEPA" filters in them for several years but now, we know that fully HALF of the air purifiers they manufacturer (11 out of 22) - don't actually have HEPA filters in them. And have NEVER had HEPA filters in them - this entire time... When Dyson went to the BBB to complain about them - they had to know Levoit was definitely falling short... at least, in the 3 air purifiers they initially mentioned... well, now it seems that it's more like 11 air purifiers instead of only 3. And as the manufacturer making these products - they fully know this. 100% So, to me - that is crazy... I would absolutely expect them to at least have some type of certifications or documentation to prove the quality of their filters... even, fake/rigged 3rd party testing results, LOL! But apparently - they don't. But that didn't prevent them from running ad campaigns touting "True HEPA" filters and performance for years and becoming the #1 HEPA air purifier in their category on Amazon. Plus, even after the meeting with the BBB they STILL ship their NON HEPA air purifiers in boxes that say "True HEPA" all over them and come with manuals that state "True HEPA" throughout them... They got caught red handed... The gig is up... but they're still messing around and being deceptive with their customers... I mean, they are straight up LYING right now. 6) So in summary, 99% of the air purifiers on the market don't filter at a HEPA level but at least many of them have some type of HEPA testing for the filters inside the units - or they utilize better quality HEPA materials, etc. Much of the reason for them not actually performing at a HEPA level is due to the poor seals inside the units. It is NOT easy to engineer a true HEPA level performing air purifier. But Levoit has fully known they don't even have HEPA filters inside 1/2 of their units. So, IMO, they have been lying to the consumers as if they do -for quite some time.... There is NO way an air purifier manufacturer doesn't know this. So, what happens is - many consumers erroneously think a Levoit Core 300 will filter just as well as an actual "Good" air purifier like an IQAir HealthPro Plus, Airpura or Austin Air Healthmate, etc. All 3 units have HEPA filters in them (or they at least "approach HEPA performance")... But in reality - the Levoit solution(s) isn't even close in performance. And many people need good filtering air purifiers for asthma or mold or you name it... so, IMO, Levoit has actually compromised the health of probably thousands of consumers who could have purchased and benefitted from better filtration solutions the past couple of years. This is a health issue - it's no joke. 7) I think what you were initially asking is - "if over 99% of the air purifiers on the market don't actually filter at a HEPA level - is it really a big deal that Levoit got busted for not having HEPA filters in their units?" And I think... yes, it is a big deal because they have a cheap $100 unit and there are different levels to the filtration game. For ex. Austin Air probably does not filter at a True HEPA level but they at least "Approach HEPA", IMO. And they have helped thousands of customers through the years with their breathing issues - including myself. A Winix 5500 for $169 doesn't actually filter at a HEPA Level but it has a "Reasonably Decent Quality" filter inside it and it actually helps a lot of people with their breathing issues. It's filter was 3rd party tested to be HEPA. They aren't perfect but decent for the money. The Levoit 300, OTOH, doesn't filter nearly as well as the other 2 solutions, IMO... It has a very cheaply made filter in comparison... but many consumers will be fooled into buying their solutions thinking they are getting something that is not nearly as good as advertised... and I can say there is a BIG difference in the quality of the filter in the Winix 5500 vs. the Core 300. Plus, these guys are still shipping the units in boxes that say they have HEPA filters in them and the manuals, say it, as well. I think this is ridiculous and consumers must know the truth. Man, that was quite a rant, lol! I hope some of that made sense. Thanks! (if you even made it this far) You probably fell asleep about 23 paragraphs up - oh well, I tried, LOL!😆

[@Lord_Mangzz]

I just got mine and it says it has h13 hepa filters in. I’m from the UK. So it appears they must have rectified this.

[@AirPurificationEducation]

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.

[@Lord_Mangzz]

@ 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.

[@AirPurificationEducation]

@@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.

What do u think about Philips air purifier? Any good?

[@AirPurificationEducation]

Thank you for your question. I've never had direct experience with Philips air purifiers but some folks have asked me and here were my responses: ****************************************************************** 30A. Philips 600i (AC0650) (@5/1/24) This has a poor internal seal with the filter. 30B. Philips AC3033/10 (@8/1/24) Philips Series 4000i/3000i Air Purifier AC4236/AC3033 What are your thoughts on Philips air purifier? Expecially the ac3033/10. Do you think they generally have a good seal? Answer: No, that internal seal does not look good from the videos I’ve seen. 11/8/24 Hi Doug, I Live in europe and can't get these. Can I trust the "Philips Series 4000i/3000i Air Purifier" filter out ultra fine particles - I would love your opinion. I live 5,5km from an airport. Thanks in advance! ANSWER I have never sold or used the 3000i or 4000i units, but based on viewing some online videos - here are my initial opinions. I think the 3000i and 4000i are pretty similar, I am guessing…: On the 3000: (11/8/24) 1) Prefilter - is not great- just OK. 2) Carbon - comes last so it can get into the air we breathe. = no good. 3) Gasket on top of filter looks decent. 9:52 of video: kzbin.info/www/bejne/d4LTfpKviJuUi80&ab_channel=ZackCustomPC 4) Seal - between filter gasket and inside of unit does not appear to be tight. 8:50 and 10:57 of this video: kzbin.info/www/bejne/d4LTfpKviJuUi80&ab_channel=ZackCustomPC And this video for the 4000i: kzbin.infoar5wv_tS4UE 5) Their Video at 50 seconds says it “Captures particles smaller than 0.003 micron and purify 99.9% of particles.” kzbin.info/www/bejne/eoevhWV7jdeAfpo&ab_channel=Philips I’ve NEVER seen an air purifier company say they filter smaller than .003 microns so, I don’t know if they even know what they are talking about, lol! Plus, 99.9% isn’t even HEPA level - which is 99.97% at .3 microns… so, their marketing folks don’t seem to really know what’s going on, IMO. 6) Also, I saw in a review they say to change the filter every 3 years and I think that is probably too long for the filter… and definitely too long for the amount of carbon they have. So no, this is not going to be a good unit for ultrafine particles. It looks like it will be a decent unit and it will improve the overall air quality in a space but it is not elite for particle filtration, IMO. 30C. Philips GoPure GP523BLACKX1 (@5/1/24) Thanks so much, hard to get those here, but will try, how big is the Amaircare Roomaide, its ok if it is big? There is one I was looking at the Philips GoPure GP523BLACKX1, at least its not a cup holder type, would it be poor compared to the Amaircare? A)The Roomaid is 8.5" x 8.5" and 7.5" tall (21.5 cm x 21.5cm and 19 cm tall). Yes, I think it is probably good if it is at least a little big. *I don't know about the performance of the Philips GoPure but in my experience - the best air purifiers come from companies that almost exclusively focus on manufacturing only air purifiers. IQAir, Airpura, Austin Air, Camfil and Amaircare - all make good to very good air purifiers and that is all they make. * Companies like Philips that make a lot of different products and "oh by the way, we also have a great air purifier, too" - tend to not make high level air purifiers. I love my Philips shaver but it is much different to make a really good filtering air purifier. *Coway makes a bunch of different products, too. And they make decent air purifiers but they don't filter as well as some of the companies that focus exclusively on air purifiers. 30D. Philips 2000 (10/5/24) Looks like a decent unit. Perpendicular placed filter but it does look pretty decent - like Winix 5500 or Coway Mighty quality.

[@AirPurificationEducation]

Thank you for your comment. What air quality tester are you using? I do think the Core 300 is good for particles in smaller spaces for the pricing (@$100). I checked the Levoit units several months ago and 11 of 22 units did not say "HEPA". So, 1/2 of them didn't have a HEPA filter - even though in the past - they said they all had one. Then, someone asked me today which ones actually had HEPA filters in them - soooooo, I ended up checking their units again and now, I only count 2 units that they say have HEPA filters in them. THAT is CRAZY! They freaking lied about 90% of their units having HEPA filters when they actually didn't. So, yeah, I do find that to be false advertising and lying to the public. Thanks!

Is Daikin air purifiers with their catch and clean technology any good or better than most air purifiers?

[@AirPurificationEducation]

Thank you for your question. Very interesting. I do not currently have any experience with the Daikin air purifiers. I am familiar with the Daikin brand to a certain degree as I've dealt with some of their mini splits in the past. So, I've looked at some stuff online about their air purifiers and I like some of what I see. In general, the elite air purifiers for particles - like the IQAir HPP and the Aeris have the filters parallel to the floor and the air comes in from the bottom and the clean air exits out the top. They leverage gravity to a certain degree to improve their seals, IMO. I see a similar arrangement in some of the Daikin models so that is definitely a good sign, IMO. I cannot currently verify their claims and the whole "water wheel" part of the solution is new to me as I only saw it a few days ago, for the first time, in an inexpensive Sharp unit. So, my knee jerk reaction is - I'd say Daikin looks like they really put some effort into their air purifier solutions and I don't know if they are elite but I'd currently put them above the "also rans".... "Also rans" by my definition are companies/brands that just do the minimal amount of research and engineering to bring a very average air purification solution to market and then market and advertise them to the max. I currently think Daikin is at least above that category... I'd have to learn more about their units in the future and I'm glad you brought this to my attention. Thank you! 👍

[@jkarthikeyan74]

@@AirPurificationEducation I have watched your videos and they are educational and informative for households planning to buy these air purifiers. In Daikin I see additional technologies like electrostatic HEPA filter and plasma ion generator. Do these actually add any benefits?

[@AirPurificationEducation]

It is tricky, I think - and I currently do not have all the answers to this. I am open mined on all this stuff. I do think there could possibly be benefit with both but it depends on how they are implemented in the solution. Anything is possible... but... The water component scares me from a mold standpoint. I'm reading their webpage and I see they are saying it is more of a humidifier - so I'm not really a fan of this... People in the US typically only need a humidifier in the low relative humidity winter months... and humidifiers are typically much higher maintenance... Plus, lots of potential for mold... so, I currently do not like this in their unit - if that is all it does - humidify... The video I saw on the Sharp unit with the water wheel - made it seem like the water wheel improved the air purification somehow... but, adding a humidifier to an air purifier may not be a good idea, IMO. Some companies put an electrostatic charge on their filters before they get 3rd party tested to improve their testing results - but the charge decreases over time... Many companies are strongly against ionization in a solution but I've seen some companies state they do it "safely"... so who knows? Do I trust they are telling the truth? How many 3rd party testing companies out there are experts at testing it's potential "negative" effects? I currently tend to trust the IQAirs of the world who can implement these technologies if they thought it was beneficial to the overall filtration of their solutions - but choose not to. The Aeris 3 in 1 was created by an MIT guy and another engineer from a top 7 global engineering school... And that was created within the past 8 years or so... and they chose not to implement ionization and whatever other technologies they could have... and the 3 in 1 filters particles at an elite level... so, I tend to believe in their engineering abilities to come up with the best solution... over other companies "adding" technologies to their solutions which may or may not be of benefit... but, they like to highlight in their marketing campaigns... like, "we have this technology and it makes us different/better". I always think - if it is so great, then why didn't IQAir or Aeris or Camfil implement it in their upper echelon solutions? @@jkarthikeyan74

I love that you go into sooooooo much detail it’s almost OCD ADHD hyper-focus just like me. Please please recommend an air-purifier the similar size of of the levoit 300/400 for a bedroom 20 meter squared (we don’t have much space in the room.) 🙏🏻🙏🏻🙏🏻. I’m in the UK.

[@AirPurificationEducation]

Hello, yeah, IDK if I have OCD ADHD but I am def. hyper detail oriented sometimes, lol! 😆 I would say that I am really high on the Leitz air purifiers and I think you can get them in the UK. They are taller than the Core 300 but cylindrical in shape so the footprint is not that large. They are EN1822 certified which is super rare at lower price points and the seal between the filter and the inside of the unit is great - esp. at the lower price point. I have never sold or owned any Leitz air purifiers so I am providing my opinion based on what I can figure from analyzing information online. That said: 1) I am a BIG fan of German engineering, in general. 2) So, we take a look at their website and they make many different products: Paper shredders, Laminating, Binding and Cutting Products, filing products, Smartphone and Computer Accessories and other solutions, as well… and they also make air purifiers. When a company makes many different products and - oh by the way - they now also make air purifiers - they are typically not elite performing air purifiers. Like Coway. Coway makes a lot of different products and they make some good air purifiers for the money but not elite filtering ones. The companies that make elite filtering solutions typically ONLY make air purifiers like IQAir, Airpura, Camfil, etc. 3) I was told by a commentor in the past that Leitz was EN1822 certified by a German 3rd party testing company - the same one that tested IQAir. That said, IQAir has been tested by at least 2 different 3rd party companies. And the IQAir HealthPro Plus was tested for the “entire system” - meaning with the filters in the unit. THAT is impressive. Most companies that show “testing results” will only have the filters tested and they won’t have the actual air purifiers tested with the filters in them. In almost every case the “entire system” testing results will be WORSE than just the filter being tested by itself. Partially because you need a GREAT seal between the HEPA filter and the inside of the air purifier. This is oftentimes NOT easy to accomplish. On the Z-2000 and Z-3000 (in US) and Z-2500 and Z-3500 (in Europe) specifically - my initial opinions are: 4) Gaskets/Seal: The Gaskets at the bottom of the filter and the top are OK looking from a quality standpoint. That said, I LOVE the fact that you screw the filter into the unit. Assuming the screwing motion enables you to really press the filter up against the top of the inside of the unit and the bottom portion. If if forces you to screw the filter until it won’t budge anymore… this would create a much better seal than the vast majority of less expensive cylindrical filter type air purifiers. And a much better seal than the vast majority of air purifiers with perpendicular installed filters. For an inexpensive solution - their internal seal appears to be much better than the vast majority of less expensive airpurifiers on the market, for sure. 5) Carbon: The tiny amount of carbon they supply with the unit is very poor and it will not help much with odors, at all. It was seemingly an afterthought. They do offer other filter options with more carbon but they make the mistake of putting the carbon last/after the HEPA filter in the Pet Filter option. Therefore, some carbon will eventually probably get into the air. So, I am not a fan of that option. But the other options where you can put the carbon filter before the HEPA seem like a good idea. 6) Prefilter: The prefilter is decent for the filters. And it is a better prefilter than most of the less expensive cylindrical filter air purifiers on the market. Therefore, the HEPA filter will not get clogged nearly as quickly as most of their competitor’s solutions. 7) Smart Features: I don’t care about the smart features as the air quality sensors on air purifiers tend not to be super accurate so I never recommend anyone purchase an air purifier based on the Smart features. Also, the apps. oftentimes tend to have issues. 8) EN1822 Certification: The filters themselves are EN1822 certified but not the “entire system”. Still, they appear to be decent quality filters for the money and there seems to exist a good seal inside the unit so I think the units will filter well for particles and definitely better than most less expensive cylindrical (and perpendicular) HEPA solutions on the market. 9) UV Light: I am not a huge fan of the UV Lights on air purifiers and I do not know how much they really improve the overall performance of the solutions. Most of the best filtering air purifiers on the market do not possess UV Lights so I currently don’t think it is a big value add. 10) Conclusion: I have to say I am impressed with these solutions from a particle filtration standpoint… and I gotta say - It looks like German engineering “did it again” to a certain degree… that said, I think the products may actually be manufactured in India. So, for example a 300 sq. ft. room with 8 foot ceilings - you can get 5 air exchanges with the Z-3000/Z-3500 - which is really GOOD! I think your room is more like 215 sq. ft. so you would be able to get even more. I’d currently put this particular unit at #12 on my list of best air purifiers for particles for 300 sq. ft. - ahead of the Rabbit Air BioGS, the Coway Mighty and the Winix 5500. airpurificationeducation.com/asthma-allergies-and-dust-particulates-in-general/ I’m tempted to put it above the Coway 400 at #10 but the 400 would be able to get double the air exchanges in an hour and that may make it actually filter the room better even though it doesn’t possess a strong seal inside the unit. But, all in all - these Leitz cylindrical filter units look very good for the pricing. I’m gonna add them to my listing in the future. Whatever you go with - if you think of it - please give me feedback on how it works for you - as I value real world feedback. Thanks!👍

[@JoeSchmoe-lq1uo]

Wow, I made it through that whole thing! So, I'm one of the folks who believed the product page title and description for this filter. I bought 2. I do like unit for all the reasons you listed near the end of this (unedited?) rambling expose. So, I'm left wondering if there's anyway I can turn this thing into a real HEPA air purifier. Are there any actual HEPA filters that will fit or HEPA filter media I can buy to make my own (I can fabricate any size frame if I can get good media to fill it)? Also, I looked at the air purifier list on your website and I'm wondering what the rankings are based on. Is it your personal experience and levels of satisfaction of customers or have you performed some form of standard testing of each with respect to filtering performance, ease of use, etc? Thanks for sharing your expertise and knowledge!

[@AirPurificationEducation]

1) Yeah, I am sorry for the ordeal. I know it was challenging and you didn’t get any compensation for your pain and suffering… but thanks for watching the entire video. I don’t think I could even watch the entire thing again. At least, not sober, LOL!😆 This video was way too long and I’m gonna try to never do that again, LOL! Imma try to limit the videos to 20 minutes max - but I can’t promise as oftentimes I initially think I have a 20 minute video but as I’m making it - a bunch of other variables come into play and it becomes a freaking full length movie, LOL! 2) “Are there any actual HEPA filters that will fit or HEPA filter media I can buy to make my own (I can fabricate any size frame if I can get good media to fill it)?” Not that I am aware of. And also the manufacturer hits certain CFM numbers with the filters they provide because the filters are more porous… and implementing less porous filters will considerably cut down on the air flow… plus, probably void the warranty. 3) “Also, I looked at the air purifier list on your website and I'm wondering what the rankings are based on. Is it your personal experience and levels of satisfaction of customers or have you performed some form of standard testing of each with respect to filtering performance, ease of use, etc?“ Good question. This specific air purification listing/ranking is based on many different variables including but not limited to the following: A) 17 years of Real World Experience with Customers and Applications: My 17 years of air purification consulting experience with thousands of customers (B2B and B2C) and their feedback on hundreds of different air filtration solutions in 40 or so different environments/applications. B) 17 years of Real World Experience with Industry Professionals/Experts: My 17 years of experience of interacting with and learning from engineers, professional air quality testers, 3rd party testing labs, and air purification manufacturers from all over the world. C) 3rd Party Testing Results: Testing results from 3rd party labs on the HEPA filters and sometimes the entire units with the filters in them. Also, learning/realizing that many 3rd party testing labs provide fraudulent testing results for air purifier manufacturers for the right amount of money. Yes, there are 3rd party testing lab “sell outs” in the industry because favorable test results are potentially worth MILLIONS of dollars to the manufacturers if they can do a good job of marketing their products. And, as mentioned in the video, the ability to compromise Amazon’s Reviews is also an awesome and quick way to make millions - esp. when you combine them with fraudulent 3rd party testing results. D) Seal Quality: The quality of the seal between the HEPA filters and the inside of the units. E) Pre-filter Quality: The quality of the pre-filter solutions inside the units. F) Amateur Testing Results: My experience of trying to test air purifiers myself with various air quality monitors. I realized the testing results were not consistently accurate. I found out very quickly that NO “amateur tester” can accurately test an air purification solution in comparison to other solutions on the market by themselves. Only a reputable 3rd party testing lab with state of the art testing equipment… and years of testing experience is able to provide accurate testing results. That said, I currently think you can get somewhat accurate test results for larger particles but they are the least dangerous to humans. Another problem is… you can make a superior air purifier “look” less effective vs. a lesser quality air purifier when you do the testing yourself… Testing air purifiers accurately is NOT as easy as most would initially believe. G) Ultrafine Particles: I take into consideration the hazards of ultra fine particles and how well the solutions are able to filter them. UF particles are the most hazardous to humans and they can cause long term health issues for people. UF particles have been linked to autism, heart attacks, Alzheimer’s, erectile dysfunction and many more issues. Because of this - I will most always include that topic in my analysis of air filtration solutions. H) Owning 5+ Air Quality Sensors: My experience with owning and using at least 5 different air quality testers… and realizing they tend not to be super accurate on a consistent basis. Their readings tend to be less accurate then most realize. I) Owning 10+ Air Purifiers: My experience of owning and using over 10 different air purifiers in my home and in the office for over 17 years. J) Hyper Analytical Abilities: Also, I can be hyper analytical depending on the topic - and this characteristic/skill affects the quality of the content on my air purification KZbin channel. Here are just 2 examples (I’m not trying to brag but I guess some folks should be aware of this): J1) I had the highest Analytics Score: I took an “Analytics Test” for an IT company with 150 employees and most were IT developers/engineers - and good ones at that. Some were from Ivy league schools and some were high level professionals from China, Bulgaria and India. That consulting company only hired really strong, talented people. I was applying for a sales position and they told me I scored the highest of anyone in the company for the Analytics test which they gave to all potential hires. After receiving my test results - they offered me 10% more money than they were initially offering and they really pursued me hard for the position. J2) I became the #1 ranked global player for an online game after I analyzed the industry: Years ago, I analyzed an online game that involved gambling which had at least 40,000 global players. There were about 6 different people with blogs who were considered the best players in the entire world - and most other players really looked up to them. Over about 18 months and about 1,300 hours of analysis (I created 16 different spreadsheets with many different variables) - I was able to beat every single player’s winning percentage. I basically became the #1 best player in the world out of 40,000+ people… but unfortunately right at the time I was becoming super successful - the entire industry was shut down by the government, LOL! But, either way… I analyzed many different variables and figured out how to become #1 out of tens of thousands of players. After accomplishing this… I realized I could sometimes possess special analytical abilities. So, those are just 2 examples of my high level analytical abilities and I have many more other examples, as well. I’m not trying to brag or anything like that… but this hyper analytical characteristic/ability is pertinent to my analysis and ranking of the air purification solutions on the market. I can sometimes possess elite analytical abilities depending on how interested I am in a topic. This ability/skill is very relevant to my brand and the quality of my content. That said, I don’t “love” air purification equipment or issues/content like I love some other topics. But I most always “try my best” because we are dealing with a health topic that can potentially affect consumers very negatively. And I do “hate” to see "perceived experts" online make poor air purification recommendations to other people - when they don’t realize there are better options out there… This type of “misinformation” or even “deceptive” information somewhat motivates me to try to create some decent air filtration content. So, I don’t know everything in this industry - no one does… I am a student of the industry and I am an Air Purification Consultant who learns new things every week and I try my best. Yeah, I know I tend to ramble but that comes with the territory, LOL! I can’t help it - I might have some level of ADHD, but IDK. So, I hope some of that made sense - Thanks! 👍

[@hairpunut]

I rememeber having a convo with you in prior comments about this device. Havent watched the review yet. So im gonna watch it now and see how it compares. Im also very curious on shark and their stances in these tests. As they are big on the true hepa filter and nanoseal as they call it lol.

[@AirPurificationEducation]

Over the past few weeks I have really been thinking a lot about the quality of prefilters in air purifier solutions and how important they are for the long term effectiveness of the solutions. If the prefilters are very poor and mostly an afterthought... like they are on the Core 300 - then the HEPA filter (or in the Core 300's case, the Main filter) will get clogged much faster and the overall solution will then tend to produce much dirtier air over time and much less/fewer air exchanges, as well. So, how well an air purifier tests for the CADR rating and all these other tests we see on the Internet... we are seeing the absolute best case scenario for the unit when they have brand new, clean filters. 99% of the time, the solutions will be performing 10, 20, 30% or worse after 8 or 12 weeks of continuous use, I think. I purposely didn't clean the wire screen prefilter on my Aeris 3 in 1 for almost 4 months (it is supposed to be cleaned monthly)... and the unit's airflow decreased by 80%. I was very intrigued by this so I will be making an effort to check the airflow of the solutions over time... as it is a super important variable to consider when figuring out how well a filter solution will be working from month 2 to 12 for folks.

[@hairpunut]

@@AirPurificationEducation I bought some aftermarket ones that come with a prefilter I use. And it comes with two per filter to keep the main portion clean for longer use. And when I was using the base filters I would vacuum them weekly. Not sure if this helped much. But my filter light replacement took a lot longer to come on.

[@AirPurificationEducation]

@@hairpunut I think getting a better prefilter is super important and can make some Main filters perform better than other filters that are of higher quality. Vacuuming the filters is something I want to learn more about.. I think some main/HEPA filters may get damaged - depending on how the vacuuming is performed. The filter light is typically based on time and sometimes time and speed... but it doesn't actually know how dirty or clean the main/HEPA filter is.... Either way... getting a better prefilter for the solution is definitely a plus, IMO. 👍

[@hairpunut]

@@AirPurificationEducation Hmm well when I filter mine. I just gently use my want to go over the outside screen for a few minutes till the dust is all collected. Then do a vacuuming of the vent holes and outside of it as well. I seen you mentioned the looseness of the filter which also bothered me as well. I stuck some cardboard on the bottom of the lid. To press the filter tighter to the seal to hopefully prevent it from leaching. I use to have a KN95 mask during covid that used the mask and a small portable device with a small h13 hepa filter. And it was leak air around the board from the fan where it drew air. So I siliconed the spaces in and made it a tight seal. I thought about doing that to this device in some capacity. But after seeing all the negatives about them. I might just go get another device. Maybe a Conway or a winix.

[@AirPurificationEducation]

@@hairpunut It sounds like you are vacuuming just fine - just like they recommend... so I think that should be fine... "I stuck some cardboard on the bottom of the lid. " Cool - I'd like to see that, lol! "So I siliconed the spaces in and made it a tight seal." - wow - you are more diligent about this stuff than most folks. You may also want to consider the Leitz TruSens air purifiers. Their cylindrical air purifiers are at the lower end of the price range... and the filters in them are from DuPont and EN1822 certified which is unheard of in this price range. + they press the filter against the inside of the unit for a better seal (there is a screw mechanism at the bottom of the unit)... So, I currently think they may be a very good option in the lower price range. www.trusens.com/c/air-purifiers/?srt=relevance Leitz is a German company and I oftentimes have high regard for German engineered products. That said, I think these units may be made in India... but I just emailed them to find out for sure. If you do get it - I'd LOVE to hear your opinion👍

I hope you become more well-known. Could you test Finnish designed Lifa Air air purifiers?

[@AirPurificationEducation]

Thank you - I have never heard of the Lifa brand but I am not too impressed with the verbiage on their website. lifa-air.com/pages/air-purifiers They state, “When purchasing a home air purifier, you should pay attention to the product’s CADR value, since this is the best indicator of the product’s capacity to purify air. Products’ CADR values can vary significantly between manufacturers, so product comparison is worth your time.” This is absolutely NOT true and therefore I already do not have a high opinion of this brand. Companies push the CADR ratings usually so they can just just sell more product but good CADR scores do not mean an air purifier filters well. I made a video on this called “Is the CADR Rating Important? NOPE! It’s GARBAGE!: kzbin.info/www/bejne/g2bKeWl_d9aDocU&ab_channel=AirPurificationEducation So the Lifa brand may make decent or even good air purifiers but I highly doubt they are elite as the elite air purifier manufacturers generally do not hype their CADR Ratings and/or don’t have particularly good CADR Ratings and/or don’t even have CADR ratings for their units. Thanks!👍

Ya know... there was a moment when I was wearing the black hood in my backyard - holding the sledgehammer... not knowing if I was going to miss the air purifier and smash one of the tiles on the patio... worrying if my neighbors were watching me... and I was looking at my blue haired teen and thinking - "I think the roles may have been reversed here... Isn't he the one who is supposed to be doing this kinda thing? And I'm supposed to be 'the mature one'?" All the while I was trying to get it done b4 my wife got home from work... cause she turns into the "Manager" of EVERYTHING... and the whole fire thing? hmmm... she wouldn't have been in favor of that and it STUNK!

I own four Levoit products. But their deceit leaves me painfully uncertain as to what to do now. In totality, I own (4) Levoits, (2) Blueair, and (1) Honeywell. All the Air Purifiers I Own: Levoit Core 400S Plasmapro Levoit Core 400S Plasmapro Levoit Core Mini Levoit Core 200S Blueair 411a (newer redesigned model) Blueair 211i Max Honeywell HPA5300B Out of them, I love my Honeywell HPA5300B the most. I see the drafts in my room moving my curtains, papers, etc. And I actually feel there's a difference in my room. I dont sneeze or cough nearly as much. I also see it working by looking at my prefilter. I know Honeywell uses a fibrous carbon filter and it is often criticized for it. However, odors aren't my primary concern and I dont expect air purifiers to rid of all odors. What is your view on Honeywell air purifiers? I like that theyre AHAM and CARB certified. They also use HEPA filters. I believe that Honeywell is more honest than their competitors by accurately stating the room size that they are recommended for by using the 4.8 ACH and not by 1 or 2 ACH that other competitors use to "wow" factor their air purifiers. I'm looking at buying an HPA5200B today as we speak 😊❤ for my work.

[@AirPurificationEducation]

Thank you for your feedback on the units you own. ***"I believe that Honeywell is more honest than their competitors by accurately stating the room size that they are recommended for by using the 4.8 ACH and not by 1 or 2 ACH that other competitors use to "wow" factor their air purifiers." Agreed, the 1 or 2 ACH marketing tactics - is really kinda ridiculous, IMO. ****************************************************************** I haven’t used the HPA5200B nor do I have direct experience with it but based on what I see online - I’d say: 1) GASKET: No gasket on the HEPA filters so there will not be a good seal within the unit between the HEPA filters and the inside of the unit. 2) INTERNAL SEAL: Not a good internal seal as the HEPA filters don’t have gaskets + nothing seems to be pushing the HEPA filters against the inside of the unit so there won’t be a good internal seal. Around 6:30 in this video shows the filters being installed: kzbin.info/www/bejne/d3eqlHiJeLCpecU&ab_channel=TheSeaboltFamily And even this guy - who seems to be an air purification novice - mentions he sees a “gap” in the filters inside the unit - after he puts the front back on… which is NEVER a good thing. 3) CARBON: Not much carbon, at all, so it won’t be great for odors but it should act decently at a prefilter to protect the other 2 HEPA filters from clogging too quickly. But again, the guy in the video said he saw a gap inside the unit where the prefilter was not covering = not good. Some folks said the optional carbon filter does improve the units ability to filter out odors - and that does make sense as it has more carbon… so that may be attractive to some folks, as well. We won’t get a ton of carbon for the $33 or so price but it does seem like it would be an improvement in this area. 4) LIGHTS: The lights on the clear back plastic shield of the unit was a pretty cool idea but they are a 100% Gimmick, IMO. But some folks will be enamored with it, for sure, LOL!😆 CONCLUSION: I think it is a decent unit for the money. It should improve the air quality from a particulate standpoint. I currently see it on Amazon for $160 so I think that is a decent unit for the money… That said, I personally, would go with a Winix 5500 or a Coway Mighty for a similar price and I believe the Mighty probably has a better internal seal than either of the other 2 units. I am not crazy about the filter seals inside this Honeywell unit, at all. Thanks!👍

@@AirPurificationEducation I appreciate the quick response. The reason I am looking for another air purifier is for my workplace. Unfortunately, I work for an employer who doesn't keep up with work environment safety. I work in laundry and every shift I work in there, I get sinus and allergy symptoms that act up. I have been bringing my Blueair 411a (the new redesigned model from a year or two ago) and it seems to help somewhat. However, I'm needing a unit that is much stronger with a high CADR. I've considered purchasing another Blueair 211i+ Max for this purpose given that it has a large 635 sq. feet of coverage in 12.5 minutes. I have considered a Winix C535 unit that is at my local Walmart and a Winix D360 and D480 that are at my local Home Depot. Of course, the ideal situation would be to have management rectify this but I know they won't do anything. I have requested this and nothing was ever done. I don't have much else regarding employment. I've applied to other places to no avail. My only option for the time being is to purchase and utiilize an air purifier to get me through so I do not get sick with bad sinus infections like I did last year - I was ill a total of 7 times due to the laundry particles(?) and 5 times I required antibiotics. Now that I have explained my situation a bit more, would you still recommend both the Winix and Coway models you recommended for this? Would the Blueair 211i+ Max or the Blueair 311i+ Max be ideal units also? I do like the looks of the Winix C535, D360, and D480 models. They make very attractive air purifiers.

Thanks!!! ​@@AirPurificationEducation

[@Vishallegal]

I have just watched your multiple videos. In an 1 yr old video "where to put your air purifier" you have talked about air exchange should be atleast 3. I had ordered Coway Airmega Aim and coway 250 air purifier. My bedroom size is 10×12×10. I'm primarily concerned about the Coway air purifiers. My 1st question is about the models of Coway purifiers which i ordered. Are they good air purifiers? I'm from india and particularly patna,Bihar. Air around me is always 150-300 and there's a lot of dust particularly in my locality. I have also ordered a humidifer as Ac dries the air and it leads to many respiratory issues and coughing problems. So my 2nd question is can i use coway 250 along with an humidifer in the abovesaid room size, won't the moisture in the air harm the hepa filter?

[@AirPurificationEducation]

I think the Coway 250 is a pretty good unit for the money... the Aim looks OK... I don't have specific experience with either unit but looking online - they seem OK. They are not elite but I think the 250 is probably somewhat similar to the 300 from a filtration standpoint - which is very reasonable... the Aim looks just OK... We are probably not going to get something very good at filtering for around $100. But it is definitely better than nothing and will help some, at least. On the humidifier issue - we used a humidifier with one of our air purifiers in a room during the winter and it did not seem to present a problem. I am sure many people use their humidifiers with their air purifiers at the same time... I have never had anyone say it was an issue for them... all that being said, I do know of a manufacturer that prefers the humidity to be at 50% or less for their specific solution but they have 18 lbs. of carbon in it... and that is what they are mostly concerned with... And I am sure most of their customers do not have their humidity at that level. So, I think it could possibly be an issue for some units and specifically for carbon issues, in general, but I think millions of people use air purifiers every day, with somewhat high humidity levels and I've never specifically heard of any problems that resulted from it. So, I would currently say you will probably be OK. I just wouldn't have the humidifier blowing the mist directly into the air purifiers - I'd probably keep them separated from each other. Good Luck!👍

Thank you for your comment 😃For Dust/Allergens/Asthma less than $200 in a 300ish sq. ft. room - I'd go with the Coway Mighty - the white color one is currently $157 which is the least expensive I've ever seen it. I got it for $229 last November. Coway Airmega AP-1512HH: amzn.to/4cLrqmU I currently have it ranked #13 on my best air purifier list for particles in 300ish sq. ft rooms: airpurificationeducation.com/asthma-allergies-and-dust-particulates-in-general/ Good Luck!👍

@@AirPurificationEducation what are your thoughts on iwave air purifier thinking of adding it to me hvac system.

[@AirPurificationEducation]

I currently do not trust ionizers and do not recommend them. I’ve seen some different companies say their ionizers are “safe” and some claim they utilize “different/better ionizing technology” which makes their solutions safe but… I currently look at it this way… by asking myself these questions: 1A) How many 3rd party testing agencies/labs out there are experts at testing for the negative effects of ionization? I don’t think many. 1B) Plus, if an ionization air purification manufacturer did get their solution 3rd party tested and the lab came back with results which showed their solution was potentially dangerous they sure as heck, are not going to publish that data. 1C) And air purifier tests by 3rd party labs can be rigged to produce certain “positive” results/outcomes, for sure. This is a problem in the industry as a testing lab in Europe recently stated that they see a lot of rigged test results in the market these days. And I had a reputable air purifier manufacturer tell me that they were approached by a 3rd party testing lab that basically told them they could get them “positive test results/outcomes”. 1D) If an air purification manufacturer wants to get positive test results from a 3rd party lab - they can find a lab that will get them those results, IMO. Money talks, for sure. 2A) If ionization was a good solution for purification/filtration… then why don’t the best air purifiers have them in their solutions? IQAir, Aeris, and Camfil do not use ionization. 2B) Aeris created the elite filtering 3 in 1 unit within the past 9 years but they don’t use ionization and their founders have master degrees from MIT and ETH Zurich - the #1 and #7 top rated engineering schools in the world (last I checked)… they chose not to use ionization in their solutions. 2C) Plus, Camfil is the largest filter manufacturer in the world. Camfil is a billion dollar company that has been in business for over 50 years and they have made air filtration solutions for NASA and many other industrial applications, as well - like pharmaceutical applications and manufacturing plants - which have very stringent filtration requirements. They are experts at creating filtration solutions for hardcore environments. And they are experts at testing filters, as well. And Camfil could easily add ionization to their solutions if they thought it was a good idea - but they don’t. So, that is my current stance on this subject… I reserve the right to change my opinions on this as I gain new information in the future or new technology/solutions become available but… this is how I currently see it. Hope that helps.👍 @@fernm7379

What about units like the Sharp KC860u, Are they all hype and marketing? Thank you.

[@AirPurificationEducation]

Thank you for the question. I don't have specific experience with that unit. That said, I just looked at a few videos on it and these are my knee jerk reactions: 1) The water component is interesting - maybe it does help with odors... IDK... but I would also be a little worried about utilizing water in my air purification solution from a mold standpoint, etc. 2) On their website they say the HEPA filter can last up to 5 years which I think is MASSIVELY improbable... IDK of HEPA filters that can even really last 3 years... shop.sharpusa.com/sharp-plasmacluster-air-purifier-with-true-hepa-filtration-and-humidifying-function-for-large-rooms-kc860u/ I've seen the HEPA filter in a video and it looks fairly inexpensive and someone in the comments mentioned their HEPA filter was starting to "tear" so IDK how it could last 5 years and do a good job. 3) On their website they mention the same for the carbon filter but even 26 lbs. of very good quality carbon from Airpura - would typically get changed every 2 or so years and that is high quality carbon . So, IDK how they think that little bit of carbon will last and keep working for 5 years... Anything is possible but... I think that is improbable. 4) The filters get inserted in a vertical manner/configuration and this is typically not how elite air purifiers arrange their filters so I def. do not think it performs at an elite level - for particles or odors/vocs. 5) I didn't see a gasket around the HEPA filter so I think it probably does not have the best seal between the HEPA and the inside of the unit. 6) It probably filters particles decently like many other "also ran" air purifier brands on the market. But not in an elite manner. So, those are my initial knee jerk reactions without really having any direct experience with the unit. Hope that helps! 👍

@AirPurificationEducation Are 2 units of a smaller air purifier better than 1 large unit when the sum of cfm of the 2 smaller units are higher than 1 large unit?

[@AirPurificationEducation]

Excellent Question!!👍 This will depend on the layout of the room, the cubic footage, what you are trying to purify out of the air and how sensitive you are to it. So there are many variables involved. For example, some people mistakenly think the CADR ratings are the most important variable to look at... and these ratings highly correlate to higher CFM units. The problem is - just because we get a lot of air exchanges with a MERV 13 filter and high CFMs - that arrangement will never be able to take out the smaller particles in the air like an IQAir HealthPro Plus or an Airpura... So, just as a hypothetical example: for someone with allergies... in many cases, it will be better to get 3 air exchanges with 99% clean air at we'll say .3 microns by an IQAir or Airpura unit than it is to get 6 air exchanges with an air purifier that does not filter, as well... we'll say only 87% at .3 microns... so it is not an exact science but the quality of the filtration is SUPER important, as well as, the CFMs... hope that made sense - good question! You keeping me on my toes, LOL!👍

[@jamesk8131]

My point is that you don't know what the filter performance is without testing it. You said you didn't believe the seal on the filter was sufficient and would probably leak. But you don't know if the seal is allowing unfiltered air to leak by because no one has tested it for leaks. If there is a true aftermarket HEPA filter with a leak proof seal on it, would it still not be worth buying? Do you know anyone who has actually tested it with an aftermarket HEPA filter? I get it, consumers should be mad if a company says that their Air Purifier has a HEPA filter in it and it doesn't. Maybe I can find a reputable company that actually sells a real HEPA filter and use that one. If I can, I'm guessing that the performance should be pretty good.

[@AirPurificationEducation]

1) "My point is that you don't know what the filter performance is without testing it. You said you didn't believe the seal on the filter was sufficient and would probably leak. But you don't know if the seal is allowing unfiltered air to leak by because no one has tested it for leaks." A: No offense, but I don’t think you realize what level of knowledge I have on air purifiers - their seals, the filtration levels, airflow and the testing processes, etc. When I say an air purifier is leaking dirty air around the filter or I “think” it will leak dirty air around the filter. Trust me (or don't) - the air purifier is going to leak some dirty air around the filter. Over 99% of the air purifiers on the market leak dirty air around the filters inside the units. And they will leak more dirty air around the filters the dirtier the filters get and the higher speeds the fans are run. This is common knowledge in the industry with the manufacturers… not with most people making air purifier content on KZbin, who are not from the industry - many of them don’t seem to realize this… But people “in” the industry like myself - know this to be fact. The only residential air purifiers that I know of that may possibly not leak dirty air around the filters may possibly be the IQAir HealthPro Plus… maybe some Airpura units… maybe the Aeris 3 in 1… maybe the Camfil City M (and they have made filters for NASA) Those units - if they do leak dirty air around the filters - they will leak the least amount of dirty air - and much less - in comparison, to the lower echelon units like Levoit, Coway or Winix. So, a Levoit 300 or Coway 400 or Winix 5500 - they will ALL leak A LOT more dirty air around the filters than the other upper echelon air purifiers I just mentioned. I don’t need a test to verify this - all I gotta do is look at the internal seals… I have 17 years of experience in this industry… I’ve dealt with engineers from MIT and professional testers with 30 years of experience, etc. etc.… and I had an air purification business owner with a master’s degree in engineering from ETH Zurich - which is rated the 6th best engineering school in the world… who sold his air purification business for $72 Million dollars - tell me, that I understand air filtration better than most of the folks in the industry. So, I don’t wanna come across as arrogant but, I ain’t guessing on this. Trust me when I say (or don't) - the seal between the filter inside the Core 300 is not strong and dirty air will DEFINITELY leak around it. 2) "If there is a true aftermarket HEPA filter with a leak proof seal on it, would it still not be worth buying?" A: Sure, of course... but do you think you are going to find a HEPA filter with a "leak proof" seal for an inexpensive Levoit unit? When even a $950 IQAir HealthPro Plus - manufactured in Switzerland - is EN1822 certified for the HEPA filter AND the performance of the entire unit... may not even be able to pull this off? 3) "Do you know anyone who has actually tested it with an aftermarket HEPA filter?" A: Nope - but that would be fun and someday I wanna venture into the "aftermarket filter" space - time permitting… because I see some folks on YT acting like the aftermarket filters are just as good as the OEM filters… which I currently do not believe is oftentimes true. 4) "Maybe I can find a reputable company that actually sells a real HEPA filter and use that one. If I can, I'm guessing that the performance should be pretty good." 4.A) Hmmm... it IS possible but... the "aftermarket" filter space is most likely filled with even more BS marketing... Here is a video I did on HEPA filters: kzbin.info/www/bejne/i6OZe2mgpq54o7s&ab_channel=AirPurificationEducation and at 18:55 in the video, I show the differences between the HEPA filter made by Austin Air (the air purifier manufacturer) vs. the aftermarket, less expensive, filter made by Filter Monster. They are not of the same quality even though, Filter Monster told me they are the same and they perform the same. Austin told me that when they test after market filters in their unit - the American made ones perform much better than the ones that come from China. So, there's that. 4.B.) Consumers also have to realize MANY air purifier manufacturers don’t try to make the best filtering solutions on the market… they simply try to “engineer” their solutions to perform well on the AHAM CADR tests. Getting good numbers on THAT test is their #1 goal. Because then they feel they can market their solutions better and sell more units… and the more porous the filter is on a unit - not too porous but not exactly HEPA level, either… and the less carbon the air has to travel through, and the more porous the prefilter… are just 3 variables that enable their air purifiers to perform better on the test…. Cause the test is only 20 minutes long with brand new filters… So, most consumers end up buying a solution with “good” CADR test results instead of getting a superior filtering solution. 4.C) So, if an aftermarket manufacturer does make a fantastic HEPA filter with a fantastic seal - and we put it inside a Levoit 300 - we can bet there will be less airflow than the original filter that comes with the unit and the CADR numbers will be worse, as well… because the AHAM CADR test places too much emphasis on stronger airflow and not enough emphasis on the quality of the filtration… So, knowing Levoit - if an after market manufacturer did somehow make the “perfect” HEPA filter for their unit, at a reasonable price… and the seal was also great… All Levoit would have to do is send it to AHAM for a CADR test (which I think is about $10,000) and it will perform much worse than the filter that actually comes with the unit. Levoit would say, “After market filters are no good for our Core 300 unit as we can see - it was 3rd party tested by Intertek and AHAM CADR certified and it performed 20% worse in the CADR testing results vs. the filter we make.” 4.D) The margins on the filter replacements are HUGE in the industry. I worked for an oil purification company and our replacement filters cost $2.50 to make but we sold them to distributors for $40 and they then sold them to the end users for $60. Sooooo… there are these issues.. as well…..

You sure do make a lot of negative assumptions without any proof to back them up. I just purchased the Levoit Core300S-P and Core 400S-P. What about the after market filters that claim to be HEPA? Are they all lying about being true HEPA filters? How would you rate these air purifiers with true HEPA filters in them? Would you give them a good review then?

[@AirPurificationEducation]

1) "You sure do make a lot of negative assumptions without any proof to back then up. " How so? The BBB busted Levoit for lying to the public about actually having HEPA filters in their air purifiers... You think the BBB was only making "assumptions"? Last I checked 3 weeks ago - 90% of the filters on the Levoit website were NOT True HEPA. 90%! But, in the past, they LIED to thousands of consumers all over the world and made millions of dollars on those lies as they said they had True HEPA filters in ALL their air purifiers. Are you OK with that? I am not. Even after the BBB ruling - MONTHS later - they sent me a Core 300 in a box and with a manual that said "True HEPA" all over them - multiple times. Therefore, many more thousands of consumers think they purchased an air purifier with a True HEPA Filter in it - when in reality, they had not. Those are fraudulent practices. 2) "I just purchased the Levoit Core300S-P and Core 400S-P. " OK, great, so you purchased a Core 300S-P. Most all air purifiers will improve the quality of the air of the room they are placed in… it just depends on what degree of improvement we are willing to invest in. That said, it seems Levoit is continuing their marketing lies as they state on the Amazon listing: “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.” LIARS! Ultra Fine Particles are .1 microns and SMALLER in size. NOT .1 to .3 microns in size. They are just continuing to profit on the ignorance of consumers. And UFP make up 90% of all the particles in the air we breathe and are also the most dangerous to humans as they can enter the bloodstream and gain access to all the organs in our bodies. So, they are lying about their ability to filter the most important and most dangerous sized particles in the air, no less. Their marketing does not possess a conscience. They added this UFP verbiage on Amazon in just the past few weeks. Here is a video on UFP and the danger they pose to humans: kzbin.info/www/bejne/fZjbfJ9np5uMicU&ab_channel=AirPurificationEducation 3) “What about the after market filters that claim to be HEPA? Are they all lying about being true HEPA filters?” Maybe some are… maybe they aren’t… I wouldn’t be surprised if some of them are lying…. Are they EN1822 certified by a reputable 3rd party lab? That would be a good place to start. 4) “How would you rate these air purifiers with true HEPA filters in them?” The next thing to evaluate would be the seal between the HEPA filters and the inside of the air purifiers. If they don’t have a very strong seal - then they won’t filter well - even if they have GREAT HEPA filters in them. 5) “Would you give them a good review then?” Next, I’d probably have to evaluate the prefilter and the reduction in airflow over time. Or if it got a good CCM test score from a reputable lab - then, yes, THAT would impress me… however, most all the air purifiers that do well on the CADR tests will perform poorly on a legit CCM test. As you can see, there are many variables involved in how well an air purifier will filter… there is more to it than just having a HEPA filter in the unit. Either way, Levoit lied to thousands of customer about having a True HEPA filter in ALL their air purifiers and they CONTINUE to lie in their marketing. I think this is pathetic… and now, I think, I’m gonna make another video on their most recent lies. Thanks for helping me uncover them - as I didn’t realize they added UFP filtration lies to their product description. My tag line is: “Bringing TRUTH to the Air Purification Industry!” and THAT is what I do…

I mean, the description of the video literally reads, "In this video, I present a staggering amount of evidence demonstrating that HEPA air purifiers are not as effective as Corsi-Rosenthal Boxes and other DIY air purifiers. I also talk to Wayne Westerman and Rob Wissmann, co-founders of the company Clean Air Kits that sells air purifiers that are quieter, more powerful, more energy efficient, and cheaper than commercial HEPA air purifiers." So, not only did he prove the CR Boxes are better than HEPA solutions but he also had 2 guys in his video who can attest to this - as they make MERV 13 purifiers themselves and they also say they are better than HEPA solutions. And they wish to sell said solutions to the masses. So, I'm thinking they probably must be right. But, IDK... What do you think? Which do you think is better?

So they got used more than once - it seems. We would also have customer service contact "poor reviewers" and bribe them to take down their negative reviews - this was standard procedure. We cannot underestimate the power of multiple positive reviews on a product - I just saw a successful KZbinr say he won't buy products off of Amazon that don't have at least a 4 star rating and he was very particular that typically it had to be like a 4.7 or above...

Get to the point.

[@AirPurificationEducation]

90% percent of the Levoit air purifiers currently (50% at the time of the making of the video)... do not have a HEPA filter in them. But in the past, they advertised ALL of them having True HEPA filters. Dyson told on them and they got in trouble with the BBB and were told to stop advertising the units as if they had True HEPA filters... However, even 4 months later - the box and manual I received for the Core 300, still said the unit contained a True HEPA filter in it. That is the gist.
