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 depending on the manufacturer. Nordic Pure Honeywell Replacement MERV 12 rated air filters are traditional 5” filters at an actual 4 3/8”. Always measure your current filter or housing to ensure proper fit.
