Maybe I just got a lemon but it's only quiet on the slowest speed. I can generally sleep with a noisy fan but it's pretty tough to sleep on the medium speed and the fastest speed is quiet flurry of motor and wind noise. The cats won't come into our bedroom when it going and quite frankly I don't blame them. It does move the air around quite well but wouldn't recommend it for the bedroom. Looks really nice if that counts for anything.
