Soft and Quiet

The choice of auto is great the only time the fan increases in speed is if it detects dirty air. Set it and forget it. Low fan speed is very quiet.

Incredible Air Purifier

I bought 2 of the Blueair 311 Auto Air Purifier for my office and bedroom. My wife has allergies and this purifier has been incredible in helping her stop sneezing in the morning. I cannot recommend it enough. Super quiet also.
