Rated 3 out of 5 by from So-So I've used the full-size germguardians in the past, so I know they -do- clean the air, albiet with needing to change the filter much more than advertised. Just got this one in today and set it up. The reason I simply can't recommend it is a common unlisted "feature" of all germguardian units--the air doesn't come straight out the front like you would think, no--it ALWAYS comes out at a 45 degree angle from the unit (Which unfortunately is blowing right on me in the dead of winter..brr!)
