20x25x5 (4 3/8) Honeywell/Lennox Replacement MERV 15 Air Filters 2 Pack Environmental Controllers Compatible with FloraFlex® 9"-10Important 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,
