Nordic Pure 21.5x23.5x1 (Actual Size: 21 1/2 x 23 1/2 x 3/4) Carrier Replacement MERV 12 Air Filters 3 Pack

Nordic Pure Carrier Replacement MERV 12 Pleated AC Furnace Air Filters provide exceptional filtration for both home and commercial environments. MERV 12 furnace filters are comparable to HVAC filters with the rating of MPR 1500-1900. Nordic Pure furnace air filters are manufactured using a heavy-duty 2-part, moisture resistant beverage board frame. As with all Nordic Pure furnace air filters, the material is electrostatically charged to attract unwanted particles. For fresh, clean air in your home and office, it is important to regularly change your AC filter, especially during home improvements. We recommend changing your HVAC furnace filter every 1-3 months, depending on your unique home or office environment. People with pets or those who suffer from allergies should change their A/C air filters more often. Replacing your air filter regularly not only improves indoor air quality, it helps your HVAC unit perform more efficiently. Important Note: Almost all air condition filters have a different Actual Size than Nominal Size 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!
