COWAY Air Purifiers for Home Large Room Up to 1,860 ft², Washable Pre-Filter and HEPA Filter for Smoke, Allergies, Pet Dander, Odor, AQI, App Control, Smart, 3yr Warranty, Airmega 250S Wifi

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...

I needed an air purifier that could handle a large open living/dining/entryway area in my apartment in dusty/smoggy NYC. Since I was already very happy with a smaller capacity Coway purifier (AP-1512HH) in a bedroom, buying the Coway Airmega 250 was a no brainer. I've had the Airmega 250 for over a year now and it has worked flawlessly, quietly (except when it goes into overdrive when I am cooking steak,) and is easy to clean and maintain. First of all, it's fairly nice looking in a simple, unassertive way that is happy to sit quietly in the background. The smaller unit I have in the bedroom is not as attractive, IMHO. Both units are pretty much "plug and play." They both monitor the air, automatically switching to a higher fan speed when indicated. If desired, the "Auto" function can be overridden, so the fan speed can be manually set. The 250 has an automatic "nighttime" setting that goes into a temporary sleep mode if no change of air quality is detected over a period of time. This is great if the unit is in a bedroom, though it will wake itself up if it detects an environmental change. I am almost never aware of the 250, the main exception is when a smoky haze escapes the kitchen, usually when I am grilling or broiling meat. The unit then goes into "Red" alert, the fan switches to "High" and the air is cleared in a matter of minutes. The filtration system is in two parts: a permanent mesh screen "pre-filter" which needs to be dusted or washed periodically, and a HEPA inner filter which can be dusted off, but needs to be replaced at least once a year, or as necessary. A red light goes off when either of the two filters needs cleaning or replacement. I've noticed a significant reduction in settled dust on my furniture surfaces. Highly recommended. EDIT JUNE 10, 2023: This unit went into auto “red alert” as soon as the Canadian wildfire smog started to engulf New York City. We shut our windows and it took the 250 (and our bedroom unit) about an hour to go from red to yellow and back to green. What a relief to have these two units!

I’ve had a variety of air filter machines over the years, this 450 version is the best quality, largest version I’ve ever owned. It’s a beast of an air filter that very well made all the way down to the filter it uses. It’s also the most high-tech as to identifying air quality and adjusting automatically. I put this one in my basement that I am remodeling and it has done a great job of cleaning the air. The initial set up is difficult to figure out. You have to remove main filter and unwrap it, in that process you remove the grill/louver part which is a flexible plastic wrap-around design, and then it’s supposed to just snap back into place and is held by magnets on one side. I’ve yet to get it all lined back up correctly, but it still works. The instructions are of little help in this regard, but once you figure out where to pull at the bottom it comes off easily. A simple sticker the says, “pull here to remove cover” would fix this issue.

Do not underestimate the size of the filter. It looks small in web pictures but this unit is large. I have a 900 square foot great room (living, dining, kitchen). I bought another air purifier that stated it could clean up to 1,000 square foot. Nope. The unit was small and could not handle the three cats and dog dander in the room. Everyone was sneezing. So I bought this Coway unit. It stands almost two feet tall and one foot wide. Has a large air intake area, different settings for strength, fan speeds, and more. When I got the unit I turned it on Turbo and our air was clean in under an hour! You could smell the difference! The noise on Turbo is loud, but the lower settings are not noisy at all. Excellent large, great room approved air purifier! Plus you can vacuum the outer filter (no buying more), and should only have to change in HEPA filter about once a year.

It doesn't come with a european power plug. Basically you will need to buy a converter from 110v to 220v just to turn it on. This version should not be on sale in Europe.

Leí muchos comentarios acerca de la app, sin embargo, ha funcionado bien; en el administrador de la red wifi se tiene que desbloquear el dispositivo, ya que lo reconoce como un intruso; una vez desbloqueado te permitirá hacer la conexión, de ahí en adelante seguirá conectado sin ninguna falla. El purificador funciona muy bien, hace poco ruido. Monitorea de forma automática regulando la velocidad en función de las partículas. Si lo recomiendo, además de que normalmente está más barato que la Versión que no tiene conexión wifi.

The best air purifier I ever own. It’s completely silent in the smart mode and the lights can all be turned off when sleeping. The APP is amazing!!! I don’t know why people complain about it, puzzles me. With the app, I’m able to control all the Coway air purifiers that I bought for my home. It gives me reports and charts to track air quality. I’m also notified of any abnormalities or drastic changes in the air. I can control my units in one screen, LOVE IT!!! The filters are pretty amazing! I noticed less dust around the house too. Also cleans out the air / smell from cooking. These units helped a lot during wildfires
