I bought two of these air purifiers while we were having some interior painting done in the house. They work really well at helping to reduce odor and keeping the air fresh. They are not too large, and you can keep then either on the floor or on a table. The fan has a noise, which is especially noticeable at Level III, but I prefer the soft noise (setting at fan level I) --- it helps me fall asleep. There is also a lights off feature that helps at night as well. Since we finished the paint project, we have been using the air purifiers daily for help circulate the air and keep it fresh. Really like them so far, and they don't emit ozone like some other air filters do.
