20x20x5 (4 3/8) Honeywell/Lennox Replacement Furnace Filters MERV 15 Plus Carbon 1 Pack complete-systems Ideal air/water balanceImportant 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!
