Important Note: Almost all furnace filters have a different Actual Size than the nominal size printed on the filter. Please measure your existing filter to ensure a proper fit. With 4″ and 5″ filters, variances are common between brands. If you are replacing a 4 3/8″ depth 16x20x4 filter in a Honeywell unit, we recommend our 16x20x5 Honeywell Replacement Filter, which measures 15 7/8″ x 19 3/4″ x 4 3/8″ (15.88 x 19.75 x 4.38).
