noises

It depends on what you call a filter. It could be anything from a new source of air in the system or something in the impeller (or not in the impeller).
 
Your best bet would be to take the filter apart and clean it. As long as you're comfortable doing it.
 
Clean the impeller housing and inspect the impeller for excessive wear. Take the unit into the kitchen and spray it out while it is upside down over the sink (to flush out dirt and build up).
 
Whenever mine makes noises, i just hit it, jiggle it around a little. Then it stops. Probably wont work for yours : ]
