4 quotesDirect organic buyer opinions about Coway Airmega 400, filtered for spam and ads.
It does the job quickly with no problem. Absolutely ...
Airmega 400 is a very good purifier for particulates pollution. It's a good purifier and moves a lot of air.
Overall, I'd recommend this unit merely for the size of it and the fact that it really isn't that loud.
Minimal noise, unit seems well built, and it seems to clean the air.
