18x24x1 (17_1/2x23_1/2) Pleated MERV 10 Air Filters 4 Pack

Nordic Pure MERV 10 Pleated AC Furnace Air Filters provides filtration for both home and commercial environments. Our MERV 10 furnace filters are comparable to HVAC filters with a rating of MPR 900-1000. Nordic Pure furnace air filters are manufactured using a heavy-duty, moisture resistant beverage board frame and the media is electrostatically charged to attract unwanted particles. The media used is better at trapping airborne particles than fiberglass filters. 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 the 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.
