COWAY Air Purifiers for Home up to 810 ft², HEPA and Carbon Filter for Smoke, Allergies, Pet Dander, Odor, AQI Monitor, Auto Mode, Timer, Filter Indicator, Night Light, 2yr Warranty, Airmega 100 White

Works very well, and SUPER quiet, especially on the lowest setting. We used it for about five months before the "replace filter" light came on. (That's why I'm looking at the listing today--to remind myself of the model number so I can order replacement filters.) I was just telling my husband last night that I can't remember the last time I heard him snore. The timing lines up with our purchase of this air purifier, so that's probably the reason! I'd definitely recommend it.

Great product. Works well. It has cut down on the pet fur and dust in my 15x20 room. Pay attention to the dimensions. It's not a tiny. It looked smaller to me so I almost didn't get it as I wanted a larger purifier. So the size is exactly what I wanted / expected. It's not silent but it's pretty quiet to me. Again, no surprise for me as I checked the db rating first.

I love my Coway air purifier. I like that it is smaller and taller because it fits anywhere. I have one in my living room and one in the bedroom. I never hear them at all, so quiet. I used to have a cough and now I no longer do.

After returning home to Texas after a 2 week vacation in the pacific northwest, and being reminded once again how much the air here (among many other things) SUCKS, and developing a case of the flu on top of that, I was like yep, not doing it, not dealing with it, I'm buying a new air purifier. I immediately noticed the difference. This thing is SO much better than our old Winix! I am allergic to dust mites and have several health conditions that not only making breathing difficult, but in cases of illness (like the flu) it's more likely to develop into pneumonia. While I'm not a doctor and I have no evidence to support my anecdote, I really do feel this helped me recover from this latest episode of the flu, and helped prevent it from progressing to pneumonia, by lessening the workload and irritation on my lungs. I also super appreciate the light toggle, that drove me nuts with my old Winix unit that I could never turn them off! The one BIG, HUGE, gripe I have: WHY IS THERE NO MUTE BUTTON?!?! Why do I have to pay another $120 for the next model up to have that feature?! Surely it's not THAT complicated to wire... My dog is noise phobic and the sound emitted from toggling the buttons on this purifier triggers her. I've managed to figure out now that if I press a button really quick and say "all done! Finished!" She seems to understand I'm not going to make the noise happen anymore and calms down. But it's super frustrating, you don't understand how scared she gets and it breaks my heart to see her like that. I was seriously about ready to eviscerate this thing and break the solder for the speaker, wouldn't be the first time I've done it, but it seems we've found a way to live with it so I don't need to. I've seen this complaint from other dog owners with the same problem though, please fix this!!

Added a couple of these 100s to smaller, isolated rooms that the 400 and Mighty2 don't draw much air from (office and laundry/dog crate rooms). They're working great. Noticeable improvement in air quality/freshness and a significant reduction in the amount of dander/dust/hair that settles on surfaces in between dusting and vacuuming sessions. Impressed.

Honestly surprised at just how quiet this is. We have it in our bedroom to help with my spouse's allergies and can't ever tell when it's even on. Most importantly, really feel like it's making a difference with the air quality. Wish this was a purchase I had made years ago.

I purchased this Airmega 100 for my utility room with a litter box to lower the dust level and remove residual odors, but during the first startup I found a high pitch noise coming from the fan. It appears the fan is out of balance since I see it wobbling during low RPMs which corresponds to the noise level. At higher fan speeds the noise goes away or is drowned out by the high airflow, but it is very annoying at low fan speed. Really wanted to love this Airmega 100 since I'm really happy with the Airmega 300 I purchased over a year ago. Not sure if this is a one-off issue, but will be returning and may look for a different solution. Included a video with audio for reference. House AC is running in background but can clearly hear the fan noise and see the fan wobbling.

So quiet and helps with my daughter's allergies. It was easy to set up and you hardly know it's there.

Received with American plug without this detail being specified.

very quiet and the light turns red when there are particles in the air and blue when it is clear. Works well and price is very reasonable. Purchased 3, one for my 94 year old mum and two for me as I have a 2 strey home. Came in real handy during the smoke invasion a few weeks back.

Really good air purifier at great price point esp for medium size apt.. Sits near the kitty litter box eliminates smells after litter box is used in a couple of minutes. Understand all the positive reviews! Very happy with purchase

We have 5 Coway air purifiers since Wirecutter recommend one of Coway's product. We have been collecting them and store every room. Especially this small one is very quite. You won't even hear it was on at night setting and it looks very nice.

A simple and effective air purifier for a bedroom. Its cylinder shape makes it easy to place on a dresser or corner table. It has an auto setting so it’ll “ramp” up when necessary to clean the air and its light system (ie. different colour lights for air quality) is easy to read laying down (you see the lights under the top of the unit) and soft enough to use as a night light (you can turn these lights off with a touch button on top). Also, the fan is very “gentle” and kind of sounds like a car driving by your home on a peaceful night (very soothing and sleep inducing). The unit can be used as a night light in a living room or hallway as well. Only “issue” I have with the product is when you push the light button to change / turn off the light, it sounds like an alarm (a softer or less alarming sound would make it the perfect / peaceful bedroom buddy).
