Nordic Pure 20x20x1 (19_1/2x19_1/2) Pleated MERV 13 Air Filters 4 Pack

Nordic Pure MERV 13 Pleated AC Furnace Air Filters provide excellent filtration for both home and commercial environments. Our MERV 13 furnace filters are comparable to HVAC filters with the rating of MPR 2200-2400 or FPR 10. Nordic Pure furnace air filters are manufactured using a heavy duty, moisture resistant beverage board frame and the media is designed to attract unwanted particles. For fresh, clean air in your home and office, it is important to regularly change your AC filter to improve indoor air quality and help your HVAC unit perform more efficiently. We recommend changing your filter every 1-3 months, depending on your environment. People with pets or those who suffer from allergies should change their A/C air filters more often. Important Note: Almost all air condition filters have a different Actual Size (the exact dimensions) than Nominal Size (the name) printed on the air conditioning filter. It is best to measure the exact size of your A/C filter and compare it to our Actual Size to be sure your HVAC replacement filter fits.
