This is our first air purifier and we've placed it in our bedroom. My wife is pregnant, with allergies, and it seems to be helping. Since we're light sleepers, we keep our unit on the lowest setting 24x7. The one complaint we have is the intermittent buzzing sound (like a very rapid vibrating phone sound) coming from the unit. The manual mentioned this may occur when the unit is over carpet (and it is), so we put a solid surface under it. The buzzing sound persists. If I shake the entire unit for a second or two, the sound may go away... only to possibly return a few minutes later. Sometimes, the sound may go away for an entire day. We've tried it with the ionizer off (same low setting) and the same result. We've only had the unit for less than a week and I'm concerned we may have to return it.
