  • Nordic Pure 18x24x4 MERV 7 rated pleated air filters 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 pleated filter, lint, household 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 7 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 1” MERV 7 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 Nordic Pure 4 inch air filter will last 6-9 months depending on your home or office environment. Important Note: Check the actual size of your current air filter or the cavity that it slides in to. All air filters have both a nominal size and an actual size.
