let us know what the noise from the fan is like.
My experience with the fan.
My thoughts about using a fan:
In my case, if there is any form of ambient sound in the room, I don’t hear the fan at all. If the window is open, if the tv or radio is on, anything at all then I can’t hear the fan. I listened for it when I first installed it.
When do I hear it? At night, when the windows are closed, tv is off, and the house is absolutely silent. The mirror is not in my bedroom, although that wouldn’t matter. My wife’s snoring can mask the sound of a 747 on liftoff.
