I have 2 Electrostatic Permanent and Washable furnace filters. They last forever and save money. (20 x 20 x 1)
Great for homes of those with asthma or health concerns.
(We had a new furnace installed and can no longer use them.)
Both are only $40. (They cost $65 new online.) One used a short time and one is new in package.
