A:Answer I can't begin to tell you how many air purifiers I have gone through. We live on a main road and the dust is awful. Always changing filters and listening to the racket.
I decided to try these. I bought one for the living room, bathroom, children's room and kitchen. They have several settings. When I am cleaning a room I turn it to quick clean. Not much noise. When I'm done, I turn it to whisper clean and you can't really hear it. They are small, so can be easily moved from floor to counter or table. I wipe them down once a week. They are wonderful!! Would definitely buy again.
