Honeywell FC40R1052

The Honeywell FC40R1052 AC filter is a high-efficiency, replacement air filter for return grille applications. Designed to capture airborne particles that circulate through the a/c filter. Nominal Dimension 16x20x4. This is a genuine Honewell air conditioning filter. The FC40R features a special design that allows it to fit in the same space as a standard 1" return grille filter, while offering filtration up to forty times more effective (versus 1" fiberglass filters). This filter will clean your air down to 0.3 microns, trap dust, pet dander, pollen, mold, bacteria and other allergens. The Honeywell FC40R1052 air filter should be replaced at least once per year for maximum efficiency. Filter life based on air quality.

Note: Honeywell has changed the depth of their return grill air filters from 4 inches down to 3 inches. Due to existing item inventory you may still receive a 4 inch filter.
