Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size" - and then you can be sure your A/C air filter fits! With the 4" and 5" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. We also carry 4 3/8 and 5 1/4 inch depth filters, this is why we ask you to compare the exact dimensions.
Nordic Pure 20x25x5 Air Bear Replacement MERV 10 air filters measure an actual depth of 4 7/8". The Pleated Plus Carbon air filters are made of a dual material where the MERV rated material has been fused together with a carbon layer. This results in less flow restriction and 33% more surface area for cleaner smelling air. It will help eliminate unwanted odors as well as trap most airborne dust and particulate matter for fresh, clean air. Odorous gases and vapors (VOC) are attracted to and held by the activated carbon material while maintaining excellent air flow properties. Each time air passes through a Nordic Pure pleated furnace filter, lint, household dust, pollen, dust mites, pet dander, bacteria, allergens, mold spores and other contaminants are removed. All Nordic Pure Air Bear replacement pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. The frame has 2 strips of foam tape on 2 sides. There is a metal mesh support grid bonded to the pleats for extra support. Our AC filter media prevents the growth of bacteria or mold, resulting in a much healthier living environment.

The effective life of your AC 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.
