Coway Airmega 250 Green True HEPA Air Purifier Beige: 800-1000 sq. ft., Quiet, Easy Filter Change, Energy Star Certified

quiet, looks nice and i love the smart setting so i don't have to do anything.

I already have a Coway and it does the job efficiently and that is why I bought another one for a different part of the residence.

Small footprint, well designed, quiet, purchased 2

I like it in general, but it’s a little more noisy that I would prefer for the bedroom

Very lightweight, sleek design, and very simple filters that are easy to replace. This is replacing a huge, bulky Honeywell HEPA filter, and I'm glad I got it!

I grew up in Korea, where it seems more customary for people to care more about indoor air quality in general. My mom in particular was a strong advocate of air purifiers and had them in every room in our house. Fast forward to now, I live in a 500 square ft. one bed-like studio with my spouse. We just found out that he has asthma that's triggered by allergies, and you know how you become your parent as you grow up, so I suggested we buy this unit. Our apartment has a bedroom area that's separated by a wall from the living room area and the kitchen. We put this air purifier in our bedroom, in front of the opening that leads to the living room, because the room is carpeted, but I wasn't sure it would pick up fumes from the kitchen, as I thought the kitchen counter kind of blocks air flow from that area. But this unit turns red as soon as we start cooking and in general seems to be really sensitive to dirty air that's farther out from its location in our apartment. We've noticed improvement in indoor air quality and I am a true believer in air purifiers now.

Does not remove as much of the dust in the air as I was hoping. If operated at the 3 level it is noisy on run at three when out of the apartment.

i have the 250 in my bedroom and the 400 on my main floor below. with allergy season in full swing and the streets + cars yellow with pollen, i come indoors to crisp, clean air and barely a sneeze. plus - they actually look ok in my house vs. looking like hospital equipment. i sleep sooo much better and no longer wake up with a congested nostril or gunk around my eyelids. they even get rid of the smell of recently cooked food in a matter of hours vs. almost a week. my house smells like i had the windows and doors open on a clear fall day. super easy to set up, clean, and maintain. can’t recommend coway air purifiers enough.

Good for removing cat litter dust in the air, but I bought it in hopes of also removing the constant smell of cat poop because they poop when I'm at work and I come home to a smelly house (I have 6 cats, so lots of pooping going on) but unfortunately it doesn't remove the smell. We also burnt a roast in the oven recently and it didn't remove the smell even after a day of running all day. So not too pleased with odor removal as it was advertised.

This little purifier is mighty. We use it in our 600ft Park Model/Tiny Home. Our stove vent recirculates the air and our airmega helps to clear and purify the air.

Does a good job and is quiet. Rated well by Consumer Reports so I thought I’d give it a try.

So grateful for this. My wife have awful allergies and we were nervous about getting a bigger sized purifier because of how loud they can be. But since we got it we don't even know its there, and she hasn't had an allergy attack after it was turned on.

I've had this for over a year and am extremely pleased with the results. I'm severely allergic to dust. Since getting this purifier I have a huge improvement in quality of life around my home. There have been times I even forgot to take my allergy meds because I have so few symptoms around the house! It's fairly quiet and looks great. The retro look fits seamlessly into my decor.

Love the simplistic function of this unit. If you want to power it on and forget it that’s all you need to do. Amazed on how quickly it notices something like cooking on the stove (smoke) from the opposite side of the house and increases its fan speed to help clean the space.

Quiet, adjusts to changing air conditions automatically. Very satisfied.

(1) Although the device always shows "Good", the fan never turns off. That operation is inconsistent with Coway instructions and appears to be a defect. (2) I am unable to access your website because your cookies are mandatory, so I am unable to communicate with Coway except through this review. (3) Your terms and conditions are inappropriate for simply accepting feedback from a customer, leaving me frustrated with the device and with Coway. (4) For those reasons I would never recommend a Coway device.

when someone is cooking in the kitchen, the airmega will detect and turn on automatically. the light turns green or red when the air needs to be filtered. i like the fan as well, it has a nice sound and looks good in my room. i only gave it 4 stars because i didn't notice the scent of cooking being filtered- i'm still testing this out its pretty new. thanks!

I now own several units of Airmega 250. Great purifiers so far, nice HEPA with pellet-based carbon filter. Airflow seems stronger than my Dyson formaldehyde purifiers. The particle sensor doesn't seem very accurate, though. Even with excellent air quality, it'd arbitrarily change color from blue -> green once in a while and kick the fan into 2nd gear. I set the sensor to "more sensitive" mode, which according to Coway customer support means that "blue" corresponds to PM2.5 being in the range of 0-10 ug/m3 while PM10 within 0-42 ug/m3. But Airmega would still turn green and back while the PM levels are nowhere near the threshold, for example, even when all my other sensors as well as data from IQAir report that PM2.5 < 5 ug/m3, PM10 < 10 ug/m3. I don't know what particle counter technology is used in Airmega 250 but clearly there's room for improvement. Note that these units are all fairly new (purchased within a few weeks) so I don't believe the particle sensors need "cleaning" yet.

The Airmega 250 does a great job in my large living room. I set it on the smart mode and it adjusts the fan speed automatically.The low setting is ultra quiet, medium is still ok and high is a little loud. All in all the unit does what it's supposed to do, clean your air. Great color to go with my interior paint. I would definitely recommend this unit.

Ok, I bought this for my husband, he has allergies and blows his nose many many times a day…. It sounds like an elephant! I was starting to loose my mind if I had to live with the elephant any longer…. This air filter has changed my life & I’m not kidding! The nose blowing is down to a few times a day, it’s amazing! I’m buying another one as soon as possible!!! Thank you for saving my sanity!
