Unlike the claims by other manufacturers of grease filters, MAR-A-THON grease filters are truly permanent. What makes them permanent is our unique "no tabs to break" design. Our exhaust grease filters are available in stainless steel, aluminum or galvanized steel construction and are assembled using a strong, durable riveted system.
U.L. Classification MAR-A-THON filters classified by Underwriters Laboratories Inc. as to flammability only after exposure to grease laden air. see U.L. Classified building materials index.
