CowayAir Purifiers for Home Large Room Up to 930 ft², Washable Pre-Filter and True HEPA Filter for Smoke, Allergies, Pet Dander, Odor, AQI, App Control, Smart & Rapid Mode, 3yr Warranty, 250S

We have had the Coway Airmega 250 air purifier for about 2.5 years. We go through about one filter per year of use. I vacuum the prefilter approximately monthly, when the reminder light comes on. (Another light comes on when you need a new main filter.) The purifier serves a large area which is foyer/kitchen/dining/living room. We run it in smart mode, so it doesn't run continuously. It cycles on and if it needs to do some air cleaning, it stays on. It definitely reacts to when I am browning meat on the stove, ratcheting up the fan and changing the led color (which indicates how dirty it thinks the air is). We also have central air/furnace with its own filter, but I like having additional filtration, especially when some wildfire smoke ends up here in the Minneapolis area. I observe it is more active when we have the really bad air quality. It is nice to feel like we are able to do something to improve our air quality.It is very quiet unless it needs to kick up the filtering to a higher level. Then the fan is louder because it is running faster, but we don't find it overly loud. We sleep down a hall from where it is located and we have never noticed any noise from it.The neutral 'greige' color is nice. White doesn't work in our home, so it is nice to be able to get something that blends in.I feel this was a good investment to have some way to monitor and clean our in-home air in this era of intermittent poor air quality. It seems durable. I have not had any issue with getting the filters - I just buy the replacement 250/250s ones from the Coway store on Amazon. One of the reasons we went with this model is that Coway seems well-established, and I wanted to make sure I would be able to get filters for many years to come.This has been a solid product for us.

I have terrible dust allergies so we've owned one of these for years and after a recent move decided to purchase another one along with a few other Coway air purifiers. I've greatly appreciated seeing it work and am often stunned by how much it's pulling out of our air. The size and design is just simple and modern enough to not draw too much attention to itself but also to look intentionally designed and not too cheap. The indicator light is very bright if you have this in your bedroom. We always opt to have the light off. And the locking function is incredibly helpful with littles around the house especially since pushing the buttons makes noise.

This is the third Conway air purifier we have. The first is now 5 years old and still in perfect working condition. We liked it so much that we bought one for our parents, and this one we purchased and placed in our large family area. We definitely notice a difference.When my son's dog would stay (Anatolian /Great Pyrenees mix), my allergies were off the chartThe Conways helps emensley

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!

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...

A must have if you’re doing any type of remodeling in your home. Gets all of the fine dust out of the air. The sensor put up pollutants pretty fast and will indicate as such. Could be a bit quieter but it can act as a sound machine for sleep.
