PermaCool® is a unique ¼" thick corrugated polypropylene filter made for the window mount air conditioner. PermaCool's dense, 3 layer, waffle weave fabric increases dust holding capacity while creating a rigid cut-to-fit air filter.

The PermaCool® is a 15" X 24" sheet for use in a standard wall/window air conditioning unit. Simply measure the existing disposable air filter currently in the unit and trim PermaCool filter pad to fit.

Air flow creates an electrostatic charge within the waffle weave that pulls in particulate such as dust, lint, pollen and other pollutants.

Every 30 days, the filter should be rinsed or vacuum cleaned. PermaCool's polypropylene media will not degrade over time as foam does. PermaCool® media comes with a lifetime warranty.
