Attention: Almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. It is highly recommended to measure your air filter and compare the exact size to the "Actual Size" provided. This is particularly important for 4-inch and 5-inch air filters, as the exact sizes can vary significantly depending on the manufacturer.

Nordic Pure's Honeywell Replacement MERV 12 air filters are a prime example. These filters are labeled as traditional 5-inch filters but have an actual size of 4 3/8 inches. Therefore, it is crucial to measure your current filter or the housing to ensure the actual size matches the filter you are ordering.

Nordic Pure's pleated air filters are manufactured using a heavy-duty, moisture-resistant beverage board frame. These filters feature a metal mesh grid bonded to the pleats, providing extra support. The AC filter media prevents the growth of bacteria and 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 helps keep your air conditioning and heating systems running efficiently, saving you 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 essential 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 Nordic Pure 20x25x5 MERV 12 Honeywell Replacement AC Furnace Air Filter is designed to fit the nominal size of 20x25x5 inches. However, due to variations in manufacturing, the actual size of this filter is 19 7/8 x 24 7/8 x 4 3/8 inches (19.88 x 24.88 x 4.38). Please measure your existing filter or housing and compare the measurements to the "Actual Size" listed above to ensure a proper fit.

This MERV 12 Nordic Pure air filter is made of an electrostatically-charged synthetic material that effectively traps airborne particulates, such as pollen, fine dust, smoke, spores, bacteria, and some viruses, as small as 0.3 microns. While the filter media does not kill germs, it does not allow the growth of bacteria or mold, eliminating the need for the addition of potentially irritating chemicals.
