Washable Electrostatic Furnace Filters - Use While Wet?
Electrostatic filters work on the same principle that causes static
cling in the dryer. The main thing I have found with them is that they
can't be cleaned too often. If they are allowed to get real dirt, the
dirt gets imbedded and the are a chore to cleanthen. If they must be
installed while they are still wet, the air flowing through them will
dry them quickly.
