20x20x5 (4 3/8) Honeywell/Lennox Replacement Furnace Filters MERV 10 Pleated Plus Carbon 4 Pack spl_cp High effciency top-bin Samsung LM301HImportant Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size" and then you can be sure your A C air filter fits! With the 4" and 5" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. We also carry 4 7 8 and 5 1 4 inch depth filters,
