Does this item works for a whole apartment?

[@pattycarljackson]

I bought this over a year ago i believe and i love it. I hav pretty bad allergies skin and regular eye and nose allergies to pollen pet hair and dander and many other things and this has helped so much.

[@tanvirsarao1400]

Is it good for rooms with lots of dust?

[@TimeWizard727]

Ty for mentioning this, it's why I'm looking into it for my partner.

[@pattycarljackson]

@@TimeWizard727 I truly recommend it they also have an updated version which is about the same price and it filters out smaller particles and it is a bit better I’d recommend the newer version.

[@Kaynos]

I have been using this exact model for over 2 years now in my bedroom and it's just amazing. Even after 2 years it is still very quiet. The only thing is that i have to turn off the UV light at night, it's too bright. Other than that, highly recommended. Last thing, the white noise it produces also help me sleep.

[@AirPurifierFirst]

I'm glad you have such a great experience with this GermGuardian, thanks for sharing!

[@EphesianRose]

Hi Kaynos, how does it do with smoke odors do you know?

[@RuthlessGrrlWhorror]

no one got sick off it from the ozone emissions it gives me and my dog started choking 2 nights in

[@EphesianRose]

[@fanily4072]

I bought this a year ago for $38 on clearance (very lucky) and it has worked pretty well. I had always thought to upgrade to something better but after watching this I am not so sure it is worth it. However, I use generic filters from Amazon that cost between $11 and $14. I would love to see reviews with 3rd party filters incorporated into this as well or maybe just do videos comparing different filters. That actually might be more important, because I buy filters much more often than I buy air purifiers.

[@AirPurifierFirst]

This is a superb suggestion, I will consider it without a doubt. Thanks a lot!

[@LCE040490]

I just wish that air would exit from the entire front of the air purifier and not just the left side. How you can air purify a room if it keeps going left?

[@TRXST.ISSUES]

The quality of your vids are top notch

[@AirPurifierFirst]

Oh, thank you so much. 😊

[@kushpaladin]

always thought these things were a gimmick. but i got one from my brother for free. placed in a 10 ft room it really does improve the air quality

[@briesoldnose4161]

I loved the smoke test

[@Sara5p]

@AirPurifierFirst Hello, I just bought this Air Purifier 🙂 What Level did you use for the smoke test? 1, 2, 0r 3? Thank you!

[@Nash1586]

Good video 👍🏼….Will this help me with the dust issue in my room ?

[@AirPurifierFirst]

Thanks. Yes it will.

[@jjs777fzr]

If the UV light is enclosed on a metal cover, and its within a plastic box, how is it treating any air ?

[@AirPurifierFirst]

As I mentioned in the video, the position of the UV-C light is not the best. Anyway, it kills some germs as a small amount of the air is going through the UV light.

[@mctwain5319]

There is a video out there from the company showing how the air passes through the UV light , and as it continuously does over hours of use, it effectively treats the air it recycles.

[@toussaintlouverture5149]

Treat deez.

[@qkcam45]

I think the UV light is supposed to be reacting to some titanium oxide ? I noticed the metal plate piece that goes in where the UV light is has some type of coating on that. maybe it is a titanium oxide coating.. not sure. I think those two act together to create something to help clean. . not sure. i myself am just learning.

[@maksteezy]

I got this back in 2016. Still working to this day. I got it to cover weed and tobacco smoke. It won't cover the smoke like that. Mama still gonna know you smoking. But it does work great. Thing is still working in 2024. I booted this fucking thing a couple times wjth steel toe boots because i had some moments.and yeah shit still works lol. Id recommend one for a small bedroom it's strong. Doesnt cover up much area compared to nowaday filters, i moved onto a winx, got a small levoit for the babies room. but now in a dayette because i covers 3k sq feet. but id def recommend the germ guardian brand for sure..

[@kika0418]

why does the air flow blow out to the right side and no air blows out to the left side?

[@EphesianRose]

wondering this too

[@TTV_KING_ROLLIE]

@airpurifierfirst, you have not answered this question?

[@Marie-fx4wh]

When the UV light is on is it dangerous. ?

[@AirPurifierFirst]

No, because the UV-C light is hidden inside the device and is well-protected, so it doesn't come into direct contact with the eyes.

[@contractseasonworldwide9378]

So you don’t have to have the UV light on for the purification process to work good you just need to turn the fan on ?

[@AirPurifierFirst]

Yes, this small UV light won't make any significant difference.

[@the2otaku822]

The UV light is there to kill mold viruses and bacteria.

[@AirPurifierFirst]

​@@the2otaku822 Yes, that's the purpose.

[@stevemaricic7585]

Very thorough video.

[@AirPurifierFirst]

Glad you liked it :)

[@abeedhasan4836]

Can you please suggest which air filter will best for a 'budgerigar aviary'? This is an indoor aviary. The size of the room is 220 sq ft. Around 400-500 budgerigars will be there. I need the air to be free from dust, bird dander and odour. Thank you!

[@AirPurifierFirst]

My girlfriend has been using the Winix 5500-2, but she had only two budgerigars, and it helped a lot. She definitely felt the difference in breathing after putting an air purifier in a room where she had budgerigars.

[@TallTrash]

Does it remove pet odors?

[@xKurtx601]

Is the UV light safe?

[@AirPurifierFirst]

It can't do you any harm.

[@brasco8721]

Would this be able to handle a 320 sq ft room or should I look for a larger model?

[@gilbert0413]

Thank you soooo much for this video!!!

[@AirPurifierFirst]

Glad you like it!

[@rae9941]

Will this good for the whole apartment? @Air Purifier First

[@AirPurifierFirst]

I don't think so. This one is intended for rooms up to 167 sq. ft.

[@2331-z4j]

How often do you have to change the filter

[@AirPurifierFirst]

GermGuardian suggests changing filter approx every 6 months.

[@dbfuture4881]

I'm missing the front vent to this air purifier is this still safe to use??

[@AirPurifierFirst]

It is okay unless you touch the fan blades while the device is working.

[@JohnEastmanExAttyAtLaw]

Where does it suck in air at? I can't feel it anywhere on mine.

[@AirPurifierFirst]

It draws the air in on the back and releases it through the grilles on the front.

[@kevinhoward9593]

ive had mine for some time. i love it. it works amazing.

[@AirPurifierFirst]

Good to hear!

[@Gameboy-Unboxings]

How is it for dust?

[@qkcam45]

have you ever tried off brand filters? I have 2 germ guardians and they make a high pitched whistle sound off and on..it is actually kind of painful noise. I have no idea how to get rid of the high pitch whistle. ? could it be because i put in after market filters? thanks

[@AirPurifierFirst]

That's strange. The unit which I tested doesn't produce an unusual sound. Maybe the filter did not fit well, so the air is making a whistling sound. Have you noticed that type of sound before changing the filters?

[@qkcam45]

@@AirPurifierFirst this is the first time using one..I live in a place that has water damage and in the fire smoke zone... I was able to find 2 units used.. they have the generic filters new ready to go.. so i can't say otherwise. It seem to be intermittent. I read some reviews on amazon and some other folks mentioned they make this sound too. I guess it is worth it to order a real germ guardian filter and see if that solves the issue. thank you for taking time to answer my question.. I really appreciate it AND your reviews. have you ever tried the "cube" that is a 20" fan with 4 hvac filters ? comparreto's cube I think is the name?? just curious. these things all get expensive..for bascially a fan and some filters!! thank you

[@AirPurifierFirst]

​@@qkcam45 Yes, it could be a solution, but the GermGuardian filter is too expensive. Maybe the better option is to purchase a new unit rather than a new filter.

[@RamanaPrabu]

Why does the airflow is seen on only one side and is that same across all units?

[@AirPurifierFirst]

This GermGuardian takes air from the backside and releases it on the front side. Please, go to 2:30 to see how the air circulates through the device.

[@louietoltolvlog9699]

Is there auto shut off or auto on when detected cleaned or odor? If this works only for knob manually, how do I know air is cleaned? How much is UV light replacement ? Is it good for smoking removal? Neighbor smokes a pot and it comes my area thru air vent in bathroom.

[@AirPurifierFirst]

No, this model doesn't have auto mode or smart sensors. It is fully manual, so you have to use an external air quality meter. But, don't worry about that, you will feel when the cleaner air, trust me. I'm not sure, but you can check the price of the UV bulb on Amazon. It's not the best option for smoke. You would need some air purifiers with better carbon filters, such as Winix 5500-2 (you can find the review on the channel).

[@yusifamda]

very informative, thanks

[@AirPurifierFirst]

Glad you enjoyed it!

[@louietoltolvlog9699]

How does clock wise knob working? Is it 24 hours ? I just want to use it for 8 hours while I’m on sleep.

[@Yaboringme]

It doesn’t have a timer It’s 3 speeds high med low

[@AirPurifierFirst]

Thanks, @philly79westchester for explaining.

[@escaflowne102]

Does this remove weed smell?

[@AirPurifierFirst]

I haven't tested it on the weed smoke, but I suppose it will neutralize it a bit.

[@blankearth5840]

How is that UV light going to do anything if it’s enclosed in a compartment like that? Is it shining on the filter at all?

[@AirPurifierFirst]

As I said in the video, the UV-C is not positioned well. That means it won't spread its light in the direction of the HEPA filter.

[@qkcam45]

this is an excellent video!~

[@AirPurifierFirst]

I'm glad you like it

[@sarahly7055]

Is the UV light safe to be on all day?

[@AirPurifierFirst]

Yes, it is absolutely safe.

[@sarahly7055]

@@AirPurifierFirst Thanks! How about the safety of the TiO2? and Ozone? Thanks!

[@AirPurifierFirst]

The AC4825 complies with UL safety standards 507 and 867. Besides, it complies with California Air Resource Board. The safety standards and regulation only allow ozone levels less than 0.05 parts per million in household air purifiers. The AC4825 has a maximum ozone output of 0.001 PPM.

This is advertised for 750 Sq ft not 150 or whatever you said. Wth is that about?

[@muzikmon2267]

I'VE WATCHED A FEW AIR PURIFIER REVIEWS OF YOURS.. AND NONE OF THEM EVER DO THE SIZE ROOM THAT THEY CAN SAY THEY CAN DO ACCORDING TO YOU 🤣 The question is how are they doing their tests and how are you doing your tests? Because on the Amazon description on this one it says that this one can clean 700 ft², one time in 1 hour.. or circulate 700 ft² in 1 hour or something like that.. I'm just curious how they do their tests? Have you ever bothered to call these manufacturers and ask them how they're making these claims? Because even though you're not directly telling them they are lying it's kind of like you are.. Because they're saying it's suited for a larger rooms but you're saying it's not.. and you've done this with just about every one of your reviews.. The question is who do we believe The manufacturers or you? I wish that someone would get to the bottom of it and find out what they're doing versus what you're doing? What equipment are they using? Is it more expensive than yours? How are they doing their measurements? It's just very bizarre?

[@AirPurifierFirst]

No one is lying. The thing is that they are marketing specialists who know how to write a good copy. I do tests in rooms that are the same, a bit smaller or a bit larger than the size manufacturer suggests. Every test is in a real-time environment, and I use a particle meter for testing purposes. After that, I compare results and conclude whether the unit is good for the suggested room size or not. Besides, I do some other tests such as putting the air purifier in my room, my brother's room, or any other room in the house, after which I/We conclude if there is any difference in air quality. Furthermore, this GermGuardian AC4825E is AHAM certified for a 153 sq. ft. room, which you can check on the AHAM website: www.ahamdir.com/wp-content/uploads/2019/03/certificate.html Lastly, the CADR for this model is very LOW, and that CADR is not enough for air purifier usage in a room of 700 sq. ft. To summarise, 1x air circulation per hour is not sufficient (it is for marketing purpose), the device has to be capable of circulating air 4x or more per hour for cleaning the room in a real-life environment appropriately.

[@muzikmon2267]

@@AirPurifierFirst yeah and that's the thing if you use that logic then none of them are good enough for the room sizes they specify.. They The experts recommend units that can be able to clean a room 4 times per hour.. And none of them can do the rooms they recommend 4 times per hour For some reason they're all based on 2 times per hour. I mean just about every single manufacturer markets their air purifier that way.. How do they all get away with this... At least I noticed with my 400S It says 1560 ft² 2 times per hour and then it says 780 ft² 4 times per hour. So at least they're telling you if you're looking for that 4 times per hour rating keep it in a 780 ft² room.. I don't know where they all got this 2 times per hour thing?

[@muzikmon2267]

@@AirPurifierFirst Isn't the only thing that matters is the particle measurements.. 4 types per hour 2 times per hour.. why does that matter. If you take a measurement of the pollution like you do I understand you do it per hour in a room.. but what if it takes 4 hours to get that 93% reduction. What if it takes one day? If it still gets you the room clean isn't that all that matters It just takes longer? So with that logic them saying it will clean a 700 ft² room one time per hour.. maybe it'll take that little machine 3 hours or so to get all those particles out of that 700 ft² room. Has anyone done this test? Has anyone taken a little machine like that let it run for three or four hours take it a measurement of the pollution and see how much it can reduce the pollution in about three or four hours? I think that these type of tests are very valid and very important I don't know why no one does them..

In my room it has a smell and for that reason I smell I carpet cleaned carpet now I dont touch my feet on floor I wear slippers. I still smell so smell linger so if I use this you think my problem go away Please respond back One love

Then it is better to look for an air purifier with a better carbon filter, such as Winix 5500-2. Keep in mind! An air purifier can neutralize odor, but it can't remove it. You have to remove the source of the odor.

UV light in a separate compartment, no airflow, making it useless

[@AirPurifierFirst]

It's not positioned the best, I agree with you. Other models from GermGuardian have the bigger and better-positioned UV light, so you could look for some other model.
