18 X 20 X 1 Dust Reduction Pleated MERV 8 - FPR 6 Air Filter (12-Pack)

Nordic Pure 18 in. x 20 in. x 1 in. Pleated Air Filters MERV 8 are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. Each time air passes through a Nordic Pure in. Pleated furnace filter it removes contaminants from the air. All Nordic Pure in. Pleated air filters are manufactured using a heavy duty, moisture resistant frame and a metal mesh support on the in. Pleats for extra support. MERV 8 furnace air conditioner filters are comparable to HVAC filters with the rating of MPR 1000 or a rating of FPR 6. Each Nordic Pure 1" MERV 8 furnace air filter captures airborne particles as small as 3.0 to 10.0 microns. The effective life of your AC air filter depends on both the inside and outside conditions in which you live. We recommend that you change your air filter every 30-90 days 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 conditioner filter. It's best if you measure your air filter for the Exact size and compare it to our "Actual Size" - and then you can be sure your A/C air filter fits.
