20x20x4 Plus Carbon Pleated Air Filter, High Capacity, MERV 7

Important 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 4in and 5in air filters there is a wider variance between the nominal and actual size depending on the manufacturer.
