I just received the filters 3 weeks ago.. I was happy that I could fine this size online because the stores don't have it. In about 2 months send me another review because I have only used my heat about 4 times.

FILTERS WHAT"S TO SAY
Comments about AAF Fiberglass 18" X 20" X 1" Panel Filter:
My landlord was terrible about changing the filter. Probably because it was an odd size. Found then on DiscountFilters.com and ordered immediately. Got a few days later and they work great. Now I can change the filter regularly.

The main ingredient in almost all water filters is activated carbon, which is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for absorption of chemicals and impurities.
