Just got a pair of Coway Airmega ProX units. I like the design; its size means it moves a lot of air at a relatively low noise level. And its pelleted carbon should be more effective than bonded carbon.
However, the carbon portion of the filters gives off a "chemical" smell. I've run them for a few weeks at top speed (speed 3) in a room with open windows for about 15 hours/day, and they're only now starting to reduce in odor, but it's definitely still there.
Obviously this is not an ideal situation, since the purpose of the carbon is to reduce room VOCs, not introduce them!
I also have a new Winix 5510, which also uses pelleted carbon, and I don't detect any smell from it.
I'll add I also tried and returned the Coway Airmega AP-1512HH Mighty. It has a very strong odor that didn't go away after running it for a week (thogh, IIRC, it was more of a plastic odor, so may have been the housing rather than the filter).
Feedback from Austin Air is to keep unit on all the time. Is that really necessary if odors are gone and gas stove has been off for an hour or two?
