I was very impressed with how light and easy to set up this air purifier was. It has air inputs on three sides, so it allows you to lay it down on the fourth side (to be on top of your dresser, or something like that). The lowest two speeds are quiet enough to be softer than our air conditioning, so they're not disruptive. The highest setting gets into white noise territory, but still isn't terribly loud. The purifier itself looks nice, it's a good color that matches my trim work. It isn't overly bulky to where it stands out too much. I did knock off one star because I have a well-rated competitor brand in my son's room, that is much smaller. That one I can truly feel the difference when I walk into his room. With this Conair one I get the sense that the air feels cleaner, but it doesn't smack you in the face as much.
