Nordic Pure 20x20x4 Pleated MERV 12 Air Filters 6 Pack

Product Description

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 20x20x4 filter in your Honeywell unit you should order our 20x20x5 Honeywell Replacement air filter that measures 19 5/8 x 19 7/8 x 4 3/8 (19.63x19.88x4.38). Nordic Pure 20x20x4 Pleated Air Filters MERV 12 are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. All Nordic Pure pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. MERV 12 furnace air filters are comparable to HVAC filters with the rating of MPR 1500-1900. This high-performance HVAC replacement filter will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance. It is important to regularly change your furnace air filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy.
