Title: Nice and Quiet
Review: I purchased this after being not satisfied with another brand I own. This air purifier is very quiet and works very well. It is the first I ever purchased(within my budget) that did not make noise to interfere with sleeping. I keep it on Medium all day and at night put it on Low. Those settings make me very glad I took a chance and bought it. I will buy another soon for other rooms. The filters are not too expensive either, very affordable.
