Polyfold Air Filters

High dust holding, industrial strength filters

Polyfold industrial air filters are excellent for general purpose filtration where high dust-holding capacity and low resistance are important. Uni-Foam and Quadrafoam™ media are used for permanent, cleanable filter applications. Polyester media is used in disposable filter applications.
