We have 2 of these monsters cranked up on Turbo. We don't sneeze as much when it's on. If you want it quieter there's some other settings to choose from.

Nice. Right now I have mine on auto so it adjusts fan speeds depending on the air quality. Id does have an ambient light sensor, so it goes into sleep mode when the lights are off. I havent found a way to disable it and end up just taking it off auto so that it stays on all night.

Ill have to check out the Whispure - Its about $260 at Amazon
