FAP02-RS 3M Filtrete Ultra Clean Air Purifier
Product Review (submitted on May 18, 2009):
Supposed to be quiet but I found this to produce a constant pulsating motor "hum" at all speeds. I'm not talking about the fan/air noise but that is also fairly noisy at med & high speeds.If you are looking for "quiet" this is NOT the product. I expected more.
