Nordic Pure 20x25x4 MERV 12 rated air filters are made of a new dual material where the MERV rated material and carbon material are pleated together to form a formidable obstacle to dust and odors. Because the carbon is also pleated, there is 3 times as much odor-fighting capability in each filter. Each time air passes through a Nordic Pure pleated furnace filter, lint, household dust, pollen, dust mites, pet dander, smog, mold spores and germs from coughing or sneezing are removed. Our filter media prevents the growth of bacteria or mold, resulting in a much healthier living space.

Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Nordic Pure 4” MERV 12 air filter will capture more than 90% of 3.0-10.0 micron contaminants and up to 90% of 1.0-3.0 micron contaminants. This high performance HVAC replacement filter will outperform non-electrostatic fiberglass 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 and work. We recommend that you change your air filter every 30-90 days to maintain maximum efficiency and indoor air quality.

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. With the 4" and 5" air filters there is a wider variance between the nominal size and actual size for the different manufacturers. Because of this, the air filter you are replacing could be called a 20x25x4 but really be the same as our 20x25x5. If you are currently using a 20x25x4 Filtrete filter in your Honeywell unit you should order our 20x25x5 Honeywell Replacement that measures 19 7/8 x 24 7/8 x 4 3/8 (19.88x24.88x4.38). This is why we ask you to measure your air filter so you aren't surprised if the air filter doesn't fit!
