IMPORTANT Note: 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. You may need to order the 20x25x4 that measures 19 1/2 x 24 1/2 x 3 5/8 (19.5x24.5x3.63). This is why we ask you to measure your air filter so you aren't surprised if the air filter doesn't fit! 

 Nordic Pure 20x25x5 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 filters. Of course, these are a list of the most well-known systems that use this size; always measure your filter housing to make sure the actual size correlates with the filter you are ordering. 5” Honeywell Replacement MERV 12 filters are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home or office. 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.

MERV 12 air filters are comparable to air filters with the MPR rating of 1500-1900, a FPR rating between Red and Blue, and an APR rating between Platinum and Diamond. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Nordic Pure 5” 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. The effective life of your air filter depends on 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 indoor air quality.
