Nordic Pure 20x25x5 Lennox X6673_X6675 MERV 10 Air Filters 2 Pack

Please note that almost ALL furnace filters have a different "actual size" than the nominal size printed on the air filter. It is recommended that you measure your air filter for the exact size and compare it to our "Actual Size". With the 4" and 5" air filters, the variance in size may be wider depending on the manufacturer. For example, Nordic Pure Honeywell Replacement MERV 10 rated air filters are labeled as 5” filters but have an actual size of 4 3/8”. It is important to measure your current filter or the housing to ensure that the actual size correlates with the filter you are ordering.

Nordic Pure pleated air filters are constructed using a heavy-duty, moisture resistant beverage board frame with a metal mesh grid bonded to the pleats for extra support. Our AC filter media is designed to prevent the growth of bacteria or mold, creating a much healthier living environment. MERV 10 furnace air filters are comparable to HVAC filters with an MPR rating of 900-1000. This high-performance HVAC replacement filter will help maintain the efficiency of your air conditioning and heating systems, saving money on utilities and costly maintenance. The lifespan of your AC air filter depends on the conditions both inside and outside of your home. It is important to regularly change your furnace air filters, especially during any home improvements, to ensure fresh, clean air in your home or office. We recommend changing your air filter every 3-6 months to maintain maximum efficiency and economy.

The nominal size of this item 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). Be sure to 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, and is ideal for normal air filtration. Nordic Pure MERV 10 is equivalent to MPR 1000 and is proudly made in the USA.
