EnvionTherapure Desktop Purifier with UV Light, 2 Fan Speeds, Quiet Operation, Filter Change Indicator, and Cleanable HEPA Type Filter for Home Use

I take this with me when I travel now, as I find I sleep better at night and wake up with less allergy when this is running to help clean the air. It is not too loud, but does provide a little white noise to assist and blocking out any other noises.
