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. If you are replacing a 4 3/8 depth 20x25x4 filter in your Honeywell unit you should order our 20x25x5 Honeywell Replacement air filter that measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38).

Nordic Pure 20x25x4 Pleated Air Filters MERV 10 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, pet dander, smoke particles, virus carriers, 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 10 furnace air conditioner filters are comparable to HVAC filters with the rating of MPR 900-1000 or a rating of FPR 7. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Nordic Pure 4” MERV 10 air filter will capture more than 85% of 3.0-10.0 micron contaminants and up to 65% of 1.0-3.0 micron contaminants. 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.
