Austin Air Bedroom Machine Air Purifier

You have three speeds: Quiet with annoying hum, Loud blower, and extremely loud blower. The motor is not brushless, but that should not be a factor. The scroll for the squirrel cage fan leaks air IN and causes a deposit of dirt from entrained unfiltered air on the grill. The top needs a noise damping pad between it and the metal of the scroll to keep the motor hum down at low speed. There is no UV lamp, and the replacement filters cost more than a competitors complete unit.

If you can stand the white noise, the filtration seems almost absolute. Musty bedroom and pet odors are effectively removed. A flashlight shined through the air in a room with the purifier seems to pass without showing any floating lint or dust (Tindall effect). This is good.

I''m hesitant to buy the $440.00 filter kit, hot glue the power cord port and the speed control to stop the dirt entrainment, and find a rubber pad and glue it in the lid to stop the low speed hum. Because of this, I think I''ll get a cheaper, just as capable model with UV and electrostatic capability..Surround Air XJ-3800 Intelli-Pro Air Purifier with Photocatalytic Filter HEPA/Carbon Filter and Germicidal UV Lamp

Sorry, Austin Air. Hell, a box fan with a 20" Hepa filter works as well for $25.00..
