DustEater Features A Proven Air Filter Design

Permatron’s DustEater is arguably the most effective washable electrostatic air filter manufactured in the U.S.A. for residential use. This air filter has been used successfully in residential furnaces for over 30 years, but the electrostatic air filter design, featuring our exclusive Accumulator Chamber construction, was originally designed for commercial applications over 50 years ago.  Designed to extend the working life of the air filter between cleanings, the Accumulator Chamber protects against dirt face loading.   Whether for standard furnace sizes, or custom built to meet a specific requirement, DustEater air filters are extremely effective electrostatic air filter for use in the home.
