Nordic Pure 20x25x4 MERV 8 rated pleated air conditioning filters are made of electrostatically charged synthetic material that attract and capture most airborne particulates in your building. Each time air passes through a Nordic Pure pleated furnace filter, lint, dust, pollen, dust mites, mold spores, odors and other contaminants are removed. Our treated synthetic filter media prevents the growth of bacteria or mold, resulting in a much healthier living space. MERV 8 air filters are comparable to air filters with the MPR rating of 500-600 or FPR rating of Green. Particles in indoor air are measured in microns, which are 1/1000 of a millimeter (a human hair is about 70 microns wide). Each Nordic Pure 4” MERV 8 air filter captures airborne particles as small as 3.0 to 10.0 microns. This high performance air filter will outperform non-electrostatic fiber-glass filters, washable filters, poly disposable filters, and will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance. The effective life of your air filter depends on both the inside and outside conditions in which you live. Nordic Pure air 4” filters have an actual depth that is a fraction of an inch smaller than the nominal size printed on the filter. This is why we ask you to measure your filter so you can ensure the filter’s proper fit. Please measure your filter for the exact depth and compare it to our actual size. We recommend that you change your air filter every 6-9 months to maintain maximum efficiency and economy.
