Ao Smith FG20252N Polyester Air Filter 20x25x2 Case of 12

Product Description

The AO SMITH FG20252N is a polyester throwaway air filter sold in a case of 12, sized at 20x25x2 inches. It is built around a chipboard frame and uses specially developed polyester fiber media bonded into an interlocking pattern of tiny lint and dust traps. This construction minimizes surface loading and prevents fibers from breaking off into the airstream. The media is rated to withstand temperatures up to 200 degrees F. HVAC technicians and facility maintenance professionals install these filters as part of routine air handler and furnace maintenance.

These filters are suited for residential and light commercial HVAC applications where a dependable, low-cost throwaway panel filter is required. The 20x25x2-inch size fits standard filter slots in forced-air furnaces and air handlers. The case-of-12 format supports bulk stocking for service contractors and property managers who rotate filters on scheduled maintenance visits. Special sizes are available directly through the manufacturer when exact non-stock dimensions are needed.

Installation Notes

Power down the air handler or furnace at the disconnect or thermostat before replacing the filter.
