Disposable Air Filters

Disposable Fiberglass Air Filters

Our disposable fiberglass air filters set the standard for quality and durability. This rigidly constructed air filter maintains its integrity where others fall short. Always the highest quality, with metal grid on the air leaving side.


We use a progressively dense fiberglass or 100% non-woven polyester media to maximize its high dust holding capacity. The metal grid is thermally bonded to the internal sides of a heavy-duty, one piece craftboard frame. The closed corner construction prevents dust laden air from bypassing the media through open corners. The filter frame is clearly marked with size, U.L. classification and air flow direction.


Our product can be used as a direct replacement for furnace filters supplied in original equipment. Standard sizes are available in 1" and 2" depths to accommodate most filter tracks. Any application can be accommodated with our special sizes, available in 1/2", 1", and 2" depths.
