Air filter options from Grainger improve air quality by removing dust, pollen, mold and other particulates from the air. Fiberglass and polyester air filters have tackifiers on the upstream side to improve particulate capture. Select a polyester filter for a higher dust-collecting capacity, or an antimicrobial air filter to inhibit the growth of bacteria. Air filter replacement promotes safe breathing conditions and ensures that your heating and cooling units are working efficiently. Find the size you need here.Close
