Lennox X6673 X6675 MERV 10 Air Filters, 2-Pack

Almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. It is best to measure your air filter to determine the EXACT size and compare it to the "Actual Size" provided. Particularly with 4" and 5" air filters, there is a wider variance depending on the manufacturer.

Nordic Pure's Honeywell Replacement MERV 10 rated air filters are traditional 5" filters with an actual size of 4 3/8". It is crucial to always measure your current filter or the housing to ensure the actual size correlates with the filter you are ordering.

Nordic Pure's pleated air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame. A metal mesh grid is bonded to the pleats for extra support. The AC filter media prevents the growth of bacteria or mold, resulting in 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 keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance.

The effective life of your AC air filter depends on both the indoor and outdoor conditions where you live. 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. Nordic Pure recommends changing your air filter every 3-6 months to maintain maximum efficiency and economy.

The Nominal Size of this product 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). Measure your air filter to ensure the exact size matches the Actual Size to guarantee a proper fit.

This item is made 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 made in the USA.
