This is, by far, the quietest fan I've owned. On "Low" from 4 feet away, you won't even know it's running except for the gentle breeze it puts out. That's how I have mine set on the wall next to my bed 24/7 except for when its I need more movement - like on hot nights. I'm a light sleeper and can easily sleep through "Med " and "High." It's more like a very quiet white noise generator. When they say it's quiet, they're not exaggerating. It's quiet.Buy it with confidence. In the unlikely event you don't like it, Amazon returns are easier than any other retailer. Just save the box and stuff.
