COWAY Air Purifiers for Home Large Room Up to 1,860 ft², Washable Pre-Filter and True HEPA Filter for Smoke, Allergies, Pet Dander, Odor, AQI, Smart & Rapid Mode, Timer, 3yr Warranty, 250

The air quality light indicator is cool - not sure how accurate it is. Great design aesthetic. Easy to set up, but haven't used any wifi connection. Only bought the wifi version because it was a better price than the non wifi. A bit on the larger size but that is to be expected with the volume it can clean. Overall, happy with it!

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.

I was excited to get this. I've done extensive research and this product was listed in the top three recommendations for air purifiers.For background, I have severe allergies to tree pollen, dust, pets, etc. I have a rabbit air purifier that will clean out a room of everything in just a few hours. I had a feral outdoor cat spraying my house and the smell was getting inside - even after clean up, the smell lingered. The rabbit was my saving grace and removed all that odor. It does an amazing job with pet dander and dust, too. It kept my allergies to a mininum. But because of the price, I couldn't afford a second one... But I really needed another air purifier for the front end of my house, as that would be my temporary bedroom while family stays with me, so I opted to buy this, while I kept the rabbit for my family. Well... I've had this product a month and it has done nothing to clean my air. My allergies have been the most severe its ever been. Only when I'm in the back with the rabbit, does it subside. This thing also alerts me every three days that the pre filter needs maintenance. When I remove it, there's very little junk present. Like why am I getting a maintenance when this thing is brand new?? However, my rabbit can be jammed pack with all the disgusting junk in its pre filter and still do a better job at cleaning my air. And oh, lemme tell you, when that cat comes around, this filter will do nothing with the odor. I specifically made sure to get a purifer with a carbon filter for this purpose. And whelp, I have to move my rabbit to the front room for a few hours to help out with the smell as this Conway can't do anything by itself. This product was such a waste of money! You get what you pay for... but for $350 I expected a little more. I even have some random off brand air purifiers I got off this site, that I put in closed off smaller rooms, and for under $50 they do a better job... I doubt I'm using this product wrong, so I wanna know where all these positive reviews are coming from. It must be from normal every day use and not for extreme situations like mine. Guess I better save up and upgrade.
