Nordic Pure MERV 14 Pleated AC Furnace Air Filters provide exceptional filtration for both home and commercial environments. Each time air passes through a Nordic Pure pleated furnace air filter, lint, dust, pollen, bacteria, pet dander, dust mites, mold spores, smoke particles, virus carriers, coughs and sneezes, smog, allergens, and other contaminants are removed. MERV 14 furnace filters are comparable to HVAC filters with the rating of MPR 2800. It is important to note that because of this high filtration and air flow restriction, HVAC systems should be rated to handle filters of MERV 14 and above. Nordic Pure MERV 14 air filters work great in newer, high efficiency systems that use HEPA filters. Nordic Pure furnace air conditioner filters are manufactured using a heavy duty, moisture resistant beverage board frame. As with all Nordic Pure furnace air conditioner filters, the material is electrostatically charged to attract unwanted particles. Important Note: Almost all air conditioner 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.
