IMPORTANT Note: Air filters have an actual size that is a fraction of an inch smaller than the standard size (also known as "nominal size"). The size printed on your air filter may NOT be the Actual Size. Nordic Pure’s 16x25x3 MERV 8 Air Bear Cub Replacement filter is meant to replace the filter for any system that requires a 3” depth. Unlike other filters where the nominal and actual sizes differ by a fraction of an inch, the Air Bear Cub Replacement has a nominal and actual depth of 3 inches exactly. Keep that measurement in mind when you are measuring your filter’s
Nordic Pure 3” MERV 8 Air Bear Cub Replacement 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 furnace filter, lint, household dust, pollen, dust mites, mold spores and other contaminants are removed.
MERV 8 air filters are comparable to air filters with the MPR rating of 600-800, FPR rating of Green, or APR rating of Gold. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Nordic Pure 3” MERV 8 filter captures up to 85% of airborne particles as small as 3.0-10.0 microns. The effective life of your air filter depends on both the inside and outside conditions in which you live. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy.
