HEPA Filter Air Purifiers
Busted up old fighter/ SInger-Songwriter/ Author –
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…

The media could not be loaded.
I’ve had this for a few months now and I absolutely love it. It looks awesome, stylish, with a modern yet retro look. It’s basically silent most of the day until it detects something in the air. It ramps up to high speed very quickly and the fan isn’t too loud that it’s overbearing. Plus, it cleans very quickly on high mode so the high fan setting doesn’t stay on too long.
I recently baked a pizza and some cheese melted onto the bottom of the oven which burned and produced a ton of smoke. As soon as I smelled it the Airmega showed a lovely red light and kicked up to high speed. The entire living room was smoky but in about 10 minutes the entire place was clear and the smell gone. I was pretty amazed. I get comments on it every time someone comes over.
The little chimes it makes when you touch a button is delicate and pleasing to the ear. It’s a very satisfying sound.
The coverage area is perfect for my 950 sq. ft. condo. I love it so much I want to buy another one even though I don’t need another. The smaller version looks just as good, so maybe I’ll get that one for my bedroom, just to have the pair.
10/10 would buy again
Edit: the reviewer called Raw has a video of his fan wobbling but that is obviously broken and not normal. So I posted a video of mine so yall can see the elegance of the unit and the smooth operating fan.

Working well. Pollution sensor fine I keep it on the ‘Smart mode’ at high sensitivity. I have it in a bedroom closed off from rest of apartment when sleeping. Unless pollution level high, it is on very low fan speed, no bothersome noise or indicator lights. Those will restart if I turn a light on but not when just screen light from checking smartphone news/social media. Air quality here generally good but feel better prepared for a smoky incident. I’ve not tested the unit in a forest fire smoke event, hoping it will help.

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!

A+++great product worked as advertised

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.

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.

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
