Nordic Pure 20x25x5 Lennox Replacement MERV 12 Pleated + Carbon 2 Pack

Please note that most furnace filters have a different "actual size" compared to the nominal size printed on the air conditioner filter. It is recommended to measure your air filter for the exact size and compare it to our "Actual Size" to ensure the proper fit. There may be a wider variance between the nominal and actual size for 4" and 5" air filters, depending on the manufacturer. Nordic Pure 20x25x5 Lennox X6673_X6675 Replacement MERV 12 rated air filters are considered the traditional 5” filter, with an actual size of 4 3/8”. Our Pleated Plus Carbon air filters are constructed with a dual material, where the MERV rated material is fused together with a carbon layer. The activated carbon material attracts and holds odorous gases and vapors (VOC) while maintaining excellent air flow properties. All Nordic Pure pleated air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame, with a metal mesh support grid bonded to the pleats for extra support. Our AC filter media prevents the growth of bacteria or mold, resulting in a healthier living environment. MERV 12 furnace air conditioner filters are comparable to HVAC filters with a rating of MPR 1500-1900. We recommend changing your air filter every 3-6 months to maintain maximum efficiency and economy. The nominal size of the filter is 20 x 25 x 5 L x RED, with an actual size of 19 3/4 x 24 3/4 x 4 3/8 (19.75 x 24.75 x 4.38). You should measure your air filter for the exact size and compare it to our actual size to ensure a proper fit. This item is designed to replace the Lennox X6673 and X6675 media air filters, making it ideal for high air filtration and odor control. Nordic Pure MERV 12 is equivalent to MPR 1500-1900 and our products are proudly made in the USA.
