Description This 20″ x 25″ polyester disposable filter is made from specially developed polyester fiber that traps dust, pollen, mold spores and more. The material’s bonded fiber construction prevents fibers from breaking off and entering the airstream. The 1″ depth allows for minimal build-up on the surface of the filter, leading to longer filter life. Each filter is surrounded by a chipboard frame for stability and has a maximum operating temperature of 200° F (93° C). These disposable filters are designed for applications such as commercial, restaurant, school and office building systems.
