Nordic Pure 20x25x4 MERV 8 rated plus carbon pleated AC air filters are made of a new dual material where MERV rated material has been fused together with a carbon layer. This results in less flow restriction and more surface area and cleaner smelling air. 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 HVAC 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 you 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. Please measure your filter for the exact depth and compare it to our actual size. This is why we ask you to measure your filter so you can ensure the filter’s proper fit. We recommend that you change your air filter every 30-90 days to maintain maximum efficiency and economy.
