Electrostatic HVAC Air Filters Permanent A/C Furnace Filter (16 X 20 X 1)

Description

Electrostatic air filters clean the air by using static electricity (a naturally occurring phenomenon). An electrostatic charge is generated by air flowing through static prone fibers. Airborne particles are attracted and held by the static charge until released by washing. Includes a Limited Lifetime warranty. Filters are 3/8" undersized. The 80% Arrestance air filter is designed for older and smaller furnace HVAC systems where the 94% Arrestance would create too large of a loss of pressure.
