Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size". 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, so please compare exact dimensions. Nordic Pure Lennox Replacement MERV 13 filters are considered the traditional 5” depth at an actual 4 3/8”. Always confirm your existing filter or housing dimensions before ordering.
