3.0 out of 5 stars Cosway AP-1512HH Mighty vs Coway Airmega 400
By J. K. Daar on April 29, 2019
I had to return this and replace it with the much cheaper Mighty, I found The top of the purifier is too tempting my cats not to jump on. That would be fine, but all the controls have a hair trigger. My cat will reset the filter change reminders, turn the device on when I'm not supervising her.
Here is a bullet point comparison between the two advantages
Mighty-
Quieter fan
Much cheaper
Easy to carry around
Cheaper filter replacement
Easy to turn on and off
Smaller footprint in your house
Easy to cover lights with tape
Mega-
Filters more air
Much Better build quality
