My Filstar XP2 makes this high-pitched hum. It's really annoying. It hasn't always done this; it started doing it about 2 years after I bought it. Any idea what's causing the hum and whether I can do anything about it?

It is almost always the impeller that goes bad. Might want to check it out.
Hmmm. Maybe I'll put the impeller of my other XP2 in that one and see if it still does that. Thanks for the thought.

I was just going to recommend looking at the impeller but figured it was too obvious. That is the first thing I would investigate.
