I have had several of these over the years. The older, heavier models worked much better for me and had the pure fan noise until they got old and worn out. This new one has a hum or whine from the motor that can be heard over the "whooshing" air sounds, no matter what volume or setting I use. For me it prevents good sleep. I must return this and get by with a regular fan.
