How to fix my filters
I have two older Whisper filters. I think they're Whisper 20's. They're clear, not black like they are now.
The problem is that they both turn on, most of the time, but then the motor just stops.
Does this sound like anything I may be able to fix, and if so, how?
Or if I would need to buy new motors, would it just be cheaper to buy whole new filters instead?
