Works great...for smaller rooms, at least!
I was skeptical of how well this filter could work. It's fantastic. It has a little more noise than I like, but doesn't bother my husband a bit. The air in our room smells fresher, less stale (we don't smoke, but it's an old house) and feels crisper, somehow. I know longer wake up with a headache every morning due to allergies to dust, dander and mold. So I am sleeping better and my room feels/smells cleaner. I plan to by more for my children's rooms.<br /><br />The only think I would change is this: to should have an on/off switch. You can turn it off by unplugging it, but I have right electrical sockets and I'd much rather just flip a switch when I want to then it off, rather than have to unplug it and lay it on the dresser. Insuppose the manufacturer assumes that one should let it run 24/7.  I have had not reason to be concerned, but if I am going to be away from home for many hours, or the weekend, I just feel better turning it off.<br /><br />Otherwise, I recommend it highly. It's small, and doesn't take up dresser or bookshelf space in our small 1920s home bedroom.
