Coway Airmega 400S Smart Air Purifier - Review (2022)
We can say, without a doubt, that Airmega 400S is a smart air purifier. Five Modes On the lowest speed, the noise level is entirely silent, and you can sleep with the Coway Airmega 400S turned on without a problem.

EXCELLENT! Works as it should
I’ve had this air purifier for 9 months in my living room. I have a couple of cats and a dog and I live in the desert which is notoriously dusty. I vacuum the pre filter once every week or two. Dust is noticeably reduced on surfaces as are my allergy symptoms when I’m home. I clean my litter boxes e...

Effectiveness

Coway Airmega 400 S Air Purifier
Amazing Air Purifier! Software needs guidance (READ ME)
First off this filter is very large and the filters within it are huge in comparison to other competitors (Detailing Honeywell AirGenius 4 / 5 , Honeywell HEPA HPA300, and Molekule below). Check out the overall measurements of the unit before ordering it - 15" by 15" by 23" tall. First off, this pur...

Best Purchase Made
It's been about 4 days of using this Purifier and I'm already convinced this was a good buy. I've been struggling with some respiratory problems for the past year now and I've bought a few Purifiers to help get clean air in my home, but every purchase was medicore to say the least. Not this machine ...

Allergy Relief

Coway Airmega 400 S Air Purifier
Saved me a fortune in antihistamines and A/C filters!
Just got my 2nd unit for the house and I could immediately breath a little easier! Cleans air beautifully. It can get a little loud at its highest level but it's still worth it! I recently discovered that I am a bit allergic to my best friend. That plus the city that we live in has horrible air qual...

Noise Level

Coway Airmega 400 S Air Purifier
Very Nice Air Purifier
Disclosure: I am a long time Amazon Prime member, but purchased my 400S from an online retailer that specializes in air treatment equipment because of better pricing and was for sure an authorized dealer (buying from unauthorized dealers usually means no warranty coverage - I have read on other revi...

Quality. You can turn off plasmawave.
The media could not be loaded. This is a well-built unit. I had a honeywell circular unit for years, then replaced it with another a few years back. It eventually died, and had been making some noises, but it worked for me. I recently bought a honeywell tower, but it started making noises after a we...
