Alternative Impeller For Aquanano 40?

[CrazyDiamond88]

The impeller on my Aquanano 40 hums a bit and since it is in my bedroom, it bothers me at night.
It's not very loud but when everything is quiet it becomes pretty noticeable.

Is it possible to get another kind of impeller that will work the same but be a little quieter?

Think you'll find that all filters hum, There's no avoiding it

I don't know, I've heard of the Whisper filter which apparently makes next to no noise.

This is a common problem that people have, having the tank near where they sleep. Surely there is a way to reduce the noise.
