Nominal Size: 20 x 25 x 4, Actual Size: 19 1/2 x 24 1/2 x 3 5/8 (19.5 x 24.5 x 3.63)
Measure and compare it to our actual size to ensure proper fit
If you are replacing a Honeywell or Lennox 20x25x4 or an air filter with an MPR rating with an actual depth of 4 3/8, please see our 20x25x5 (4 3/8 actual depth)
Nordic Pure MERV 12 is equivalent to MPR 1500-1900
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.
If you are replacing a 4 3/8 depth 20x25x4 filter in your Honeywell unit you should order our 20x25x5 Honeywell Replacement air filter that measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38).
