Nordic Pure 24x24x4 (3 5/8) Pleated MERV 8 Air Filter 1 Pack

Nordic Pure 20x24x4 Pleated Air Filters MERV 8 are made of 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 8 furnace air filters are comparable to HVAC filters with the rating of MPR 800. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Nordic Pure 4” MERV 8 furnace air filter captures airborne particles as small as 3.0 to 10.0 microns. This high-performance HVAC replacement filter will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance.The effective life of your AC air filter depends on both the inside and outside conditions in which you live.  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.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".
