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 7/8 and 5 1/4 inch depth filters, this is why we ask you to compare the exact dimensions.

Nordic Pure 20x20x5 Honeywell Replacement MERV 12 rated air filters are what is considered the traditional 5” filter at an actual 4 3/8”. It can replace not only Honeywell but Lennox, Carrier, and Bryant air filters. Of course, this is just a list of the most well-known systems that use this size. You should always measure your current filter or the housing to make sure the actual size correlates with the filter you are ordering. 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. With each pass through the pleated furnace air filter, the air in your living environment improves. 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 pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. 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.

MERV 12 furnace air conditioner filters are comparable to HVAC filters with the rating of MPR 1500-1900 or a rating of FPR 9. This high-performance HVAC replacement 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 effective life of your AC air filter depends on both the inside and outside conditions in which you live.  It is important to regularly change your furnace air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy.
