Alen T500 Air Purifier

Product Review (submitted on April 7, 2015):

So quiet i have to keep checking if its actually I've had the T100 going steadily in my bedroom for the last two years. It too is incredibly quiet. It's getting a little tired and weezy so i put it in another room. Bought a 500 for the bedroom and another for the living room. I have dust mite allergies and i'm not a very fastidious house cleaner. I think they help.
