CowayAir Purifiers for Home Up to 1,748ft², True HEPA Filter for Smoke, Allergies, Pet Dander, Odor, Air Quality Monitor, Auto&Eco Mode, Timer, Filter Indicator, 3yr Warranty, 200M, White

I first used this air purifier in my child’s room. My child has seasonal allergies, and after using this air purifier, the allergy symptoms definitely improved, and the air in the room feels fresher.I liked the Coway airmega purifier so much that I replaced the previous one in the living room with a Coway model. Since then, the air quality in the entire house has improved.One of the best features is Eco Mode. When we’re out or when there’s no one home, I leave it running in Eco Mode, and it keeps the air quality great all day without wasting energy. After a day out, I come home to fresh, clean air. I’m really happy with the results.Replacing the filter is easy, and the noise is minimal, so it doesn’t disturb me even in the living room.I highly recommend this air purifier for anyone sensitive to allergies or dust!It’s not only great in performance, but the design is sleek and fits well with the decor of the house

This product is definitely worth the money. It keeps the air in my home so clean, it is truly exceeding my expectations. As the weather shifted into spring, the pollen has been a bugger but step into my home and my surfaces are pollen free and nearly dust free. I had a bit of a musty smell in one of my closets and set this up in there and within a matter of a few hours, the smell was completely gone and has stayed gone. It is easy to use, built well and makes little to no noise (except when turned to the highest setting which I only use when frying something). Being that it is pretty compact and very lightweight, It is easy to move around the house. I would definitely purchase this product again.

I was planning to buy a purifier to help with the pollen and food smells and chose this model. It has worked very well for a 2 bedroom apartment. Its not too big, not too small, so I keep it next to the dining table and the system is set to Auto or Eco. Both detect air quality and adjust the fan speed accordingly. In terms of noise levels, I agree with most reviewers that it’s very quiet on low settings; high setting being comparable to the noise a kitchen extractor makes.Allergies and sneezing are less in these few weeks, and the smell of food definitely does not linger as long as before. In a 2-3 hours it’s basically gone. I hope to keep updating as I go but I can already tell this one is a keeper.

I’m lucky enough to walk through my urban environment without any chemical or scent sensitivities. But the HEPA filter in these Coway units are so chemical smelling that I immediately get a headache and nausea from them. It takes a long time of running the unit for the scent to dissipate. The Wirecutter review mentions this horrible, caustic scent but says it’s a resolved problem. It is not. Coway even mentions it in their FAQ. They know it’s a problem. I emailed and asked for a replacement filter because of Wirecutter’s assertion that it was a thing of the past, so surely I just got an old filter? Coway will not send you a new filter, they just tell you to run it in a room with a window open (so if it’s the middle of winter or the height of summer, you have to wait for spring or fall?). For context: I bought one unit, the one with the grid face, in September 2024, when it was 113°F in Arizona and it came with a toxic off-gassing filter. I left it outside for a week and then braved running it inside until the smell dissipated (obviously, one cannot open a window in Arizona in the summer, it doesn’t go below 100°F at any point in the day or night for many months at a time). It was a long 5 days of putting up with that smell. I ordered another unit in October, this time the other style that looks like an iPod shuffle face. Again, the filter smells noxious, and gives me a headache. Upshot: I will not be buying replacement filters directly from Coway, luckily there are lots of third-party offerings out there. Coway KNOWS this is a problem and doesn’t seem interested in solving it, despite making a product promising to make your environment less, not more, unhealthy. Wirecutter has dropped the ball by suggesting it’s no longer an issue. If, like me, you don’t have a million spare rooms to run an off-gassing air polluter behind a closed door with a window open until it converts to an air-cleaner, I’d strongly suggest purchasing from another brand.Update: I got another Coway Airmega. I wanted one for my bedroom. I’m jealous of the people who seem to be getting filters without the smell problem, because it happened again with this unit. It smells like you’ve walked into a cheap carpet warehouse where they also happen to be storing slightly burned sneakers. I’ve never experienced that with the HEPA filters for my AC or any of my vacuums, it’s a Coway specific thing. It’s also mentioned in many reviews if you search here. It’s bad and it lasts for days, over 7 days for the smell to lessen this time.Once that’s over and you’ve just gone ahead and breathed in all those noxious fumes, the unit works great! The auto function is awesome, it really reacts to things that kick up dust, like if I shake out the pet bed or scoop cat litter, sending the unit into high mode for a few seconds in response. When it’s on speed one, which it is most of the time on auto-mode, it’s almost completely silent. I like that I can turn off the large blue air quality indicator light, but why in the world don’t the two green lights that indicate speed also turn off with it? The unit is pretty far from my bed so it doesn’t bother me at night, but they are really bright. I’ll get my replacement filters from someone else, because I’m not going through that awful sick feeling of off-gassing the Coway brand filters again, but I do like the units and how they function a lot.

Love this air purifier so much I bought two. The first one I purchased four years ago for a loft/office to manage cigarette, dog, and Mary jane odors. It is never off. NO ONE KNOWS!! My home has no smoke/animal odor. I use the ionizer only when I am vacuuming then turn it off after. I keep it on constantly at level 2, where it sits behind my chair. The sound does not interfere with phone/tv. The third level is really loud but can be used for fast purifying or for when you’re not home. Filter management is important. I rinse the front filter screen and carbon filter every 2 weeks. ( I have six carbon filters that I rinse and reuse for six months ) It is amazing how well this filters. The big filter I change every 4 months because we are heavy smokers. The second one we have in the bedroom/first floor. This is a really great air purifier!

This was originally recommended as a Best Buy through NY Times Wirecutter and it is worth the money. The filter replacement lights are helpful. When you replace the filters you can see it effectively working with all the dust/etc that it collects. When you cook you can see it automatically shifting into high gear to accommodate and filter the extra pollutants in the air. It’s about the height of an ottoman, but skinny. Making it easy if place in your room.I’ve had other purifiers and they’re definitely not as high quality and effective as this one.
