COWAY Air Purifiers for Large Room Whole Home Up to 3,285ft², True HEPA Filter for Smoke, Allergen, Pet Dander, Odor, PM(1, 2.5, 10), AQI, Turbo Eco Mode, Energy Star, 3yr Warranty, Airmega 450 Beige

Excellent air purifier and very simple to pug in and go! We have a new restaurant in our building at street level (NYC) and the food smell is very strong at certain hours of the day, this took care of the smell completely in a VERY LARGE space. The smell was leaching into furniture, but there have been zero smells since using this. You can't tell its running as its very quiet unless its on Turbo mode, which moves a ton of air quickly. I would imagine this would be great in an apartment or near a kitchen. Auto mode has been great with taking care of it. Easy to move around the space, but I've pretty much left it in one area. Keeping my eye out for the different types of filters or any filter replacement period, so hopefully those roll out soon. The machine has been running 24/7 for over a month and a half and filter is still at 85%. The unit is overall larger than I expected, but it looks sleek enough to blend in with pretty much any décor. Would absolutely recommend.

I did not make this purchase out of want ??? I'm very, very sick (have been for more than a year) & I needed something effective & affordable. WORST THING? I moved into new apt. only to find my ground level unit sits right next to the main drier vent. Because it's ground level, what flows in is almost impossible to get out, and hot drier air flows in & down. I almost gave up/ I did lots of research (enough to learn what I feared)??? I'll tell you what that is in a moment. You have to do deep research on a product like this/ there's so many options & most are useless (I'm sorry but it's true). I always read until I find those rare technocratic users who truly put products through their paces. THE TRUTH? Many of the high reviews for a majority of the available units are inspired by digital features (lights & listed options). It seems the old honeywell units were legit (really pulled dust, etc.)? But? They've become flimsy & flawed (even filters no longer seating well)... I never saw one of these COWAY units listed among either "featured" products or through "highest review" search option??? A real & smart user did a head to head with multiple brands & was truly impressed with COWAY. I punched the company name in (didn't even know what they looked like)... This product is exceptional in every way. It truly hauls air through one very large multistage filter (only 1 needed as replacement yearly). It claims to do a 900ft sq. room, & I believe it. PROBLEM? A unit is only as good as the convection it can create/ This is limited by irregularities in ANY space—lest you're buying a hulking industrial unit. I'm sicker than I wanna discuss here, I'm not an average user & the stakes are deadly serious. Before I even purchase this unit, I spent 2 days in the new apt. setting up fans & feeling the currents & air flow such that if I found an appropriate unit—I'd be able to effectively cycle all air through it. I say again, I almost gave up (I could easily see one MOSTLY must buy a larger, more industrial value unit if one has truly serious problems—and I don't have the money for such a purchase). THIS UNIT DOES NOT HAVE THE "S" DESIGNATION/ IT DOES NOT UTILIZE WIFI... NO—THIS IS A GOOD THING??? WHY WOULD YOU EVER NEED THE FEATURE & IT ADDS $100 TO THE PRICE... AND? IT'S BEEN MESSING WITH PEOPLE'S WIFI MORE GENERALLY (taking it down—in fact). There's a pre-filter screen & it works. The computer keeps track of the air volume. I started to notice eye irritation the other day & I cleaned the pre-filter (EASY PEASEY). The next morning? The light indicating time for the precise cleaning was on... IT WAS RIGHT ON THE MONEY!! The main filter is massive with a micro-fit (set in easy & snug across all sides/ no loss of seal anywhere). I think the replacement is $26 & you only need 1 every year... CRAZY/ SO MUCH CHEAPER TO OPERATE ON TOP OF REALLY CLEANING LOTS OF AIR. Pulls smells fast & effectively. It keeps track of the air quality & it works (it tells you when something is introduce into the air via simple active color bar). I've been running it in highest haul setting. I brought the fan down to medium yesterday & the slowed air-flow seemed to find even more particulates (I have air moving fast everywhere with fans & I think slowing down a bit helped—ironically). On top of everything else—it's an elegant looking model. It doesn't look like—or try to be—a smart-buddy (like some smart pod with lots of useless lights). I've been poor most of my life & when I do make a purchase, I do my research. I don't have money to burn & the stakes are very, very high for me (carbon monoxide is building in my blood, suffocating me slowly & horribly). I'm fighting for life/ I need anything that can help CUS I have emphysema already & nobody really knows why 02 is accumulating? Probably a black mold infestation in last apt... WHAT A PRODUCT/ I WISH I COULD SAY I'D BUILT IT... I've done a bit of inventing in my life. I'd like to think that if I did build an air purifier? it would look & function just like this... GET IT !!! SERIOUSLY...

When the air quality is poor it sounds like a plane during take off, but it gets the job done quickly and the app gives me real time updates about the small (e.g. smoke) vs larger air particles (e.g. dust) needing to be filtered.I can turn off all of the lights while still using the filter overnight so it's not bright at all. Sleep mode is really quiet.

So far it has worked really well. I like the air quality light on top, seems to be accurate but not sure why blue is best not green? The only problem I had was the unit seemed to vibrate loudly at random times during the night and wake me up even on low speed. If you tapped it, the noise went away for a while. My solution was to grab two tiny magnets and stick them back to back on each side of the front screen. This has completely fixed the issue. I suspect you could glue a small weight inside and it would also work. Seems odd the manufacturer did not fix this problem. Other than that, its great!

Super Duper!! Excellent quality and it looks great. Very happy with the product.

Keeps air clean and it's a good size, not too big or too small. Since it has a nice design, it blends in well with my furniture/decors without sticking out like a sore thumb like a lot of other air purifiers on the market.

Perfection. Beautiful, quiet, strong.
