Lennox X6673_X6675 MERV 12 Replacement Air Filter 2 Pack

It is crucial to note that almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. To ensure a proper fit, it is best to measure your air filter and compare it to our "Actual Size" specification. This is particularly important for 4" and 5" air filters, as the variance in size can be more significant depending on the manufacturer.

The Nordic Pure Honeywell Replacement MERV 12 rated air filters are a classic example of this discrepancy. Although these filters are labeled as 5" filters, their actual size is 4 3/8". Therefore, it is essential to measure your current filter or the housing to confirm that the actual size corresponds with the filter you intend to order.

Nordic Pure's pleated air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame. These filters feature a metal mesh grid that is bonded to the pleats, providing extra support. The AC filter media used in these filters prevents the growth of bacteria or mold, resulting in a much healthier living environment.

MERV 12 furnace air filters are comparable to HVAC filters with an MPR rating of 1500-1900. This high-performance HVAC replacement filter will help maintain the efficiency of your air conditioning and heating systems, ultimately saving you money on utilities and costly maintenance.

The effective life of your AC air filter depends on the indoor and outdoor conditions where you live. It is crucial to regularly change your furnace air filters, especially during any home improvements, to ensure fresh and 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 product is 20 x 25 x 5 L x RED, while the actual size is 19 3/4 x 24 3/4 x 4 3/8 (19.75 x 24.75 x 4.38). It is essential to measure your air filter 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 an ideal choice for high-efficiency air filtration and those with moderate allergies. Additionally, the Nordic Pure MERV 12 filter is equivalent to an MPR 1500-1900 rating.

Lastly, it is important to note that this product is made in the USA, ensuring quality and reliability.
