Nordic Pure MERV 12 Air Filters 2 Pack

Almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. Therefore, it is best to measure your air filter to determine the EXACT size and compare it to our "Actual Size" specifications. For 4-inch and 5-inch air filters, there is a wider variance between the nominal and actual size, depending on the manufacturer.

For example, if you are replacing a 4 3/8-inch depth 20x25x4 filter in your Honeywell unit, you should order our 20x25x5 Honeywell Replacement air filter that measures 19 7/8 x 24 7/8 x 4 3/8 (19.63x24.88x4.38) inches. This is crucial to ensure proper fit and performance.

Nordic Pure 20x25x4 Pleated Air Filters MERV 12 are manufactured using a heavy-duty, moisture-resistant beverage board frame. These filters feature a metal mesh support grid bonded to the pleats for extra strength and durability. Composed of electrostatically charged synthetic materials, Nordic Pure filters effectively attract and capture most airborne particulates in your home, including pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

MERV 12 furnace air filters are comparable to HVAC filters with an MPR (Microparticle Performance 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.

Regular filter changes, especially during home improvements, are crucial for maintaining fresh, clean air in your home or office. We recommend changing your air filter every 3-6 months to ensure maximum efficiency and economy.

The actual size of the Nordic Pure 20x25x4 MERV 12 Pleated AC Furnace Air Filter is 19-1/2 inches by 24-1/2 inches with a depth of 3-3/4 inches. It is important to note that almost all filters are slightly smaller than the nominal size printed on the filter. Therefore, measuring your filter for the EXACT size and comparing it to our "Actual Size" is essential to ensure a proper fit.

With the 4-inch and 5-inch filters, there are many different exact sizes for the various HVAC manufacturers. Your filter may be labeled as 20x25x4, but it could be the same as our 20x25x5 filter. This is why we strongly recommend measuring your filter before ordering to avoid any surprises.

Nordic Pure air filters do not kill germs, but the filter media does not permit the growth of bacteria or mold. As a result, it is not necessary to add any potentially irritating chemicals to the air filter to kill germs.

Made in the USA, Nordic Pure MERV 12 air filters are equivalent to MPR 1500-1900 and are a reliable choice for maintaining the optimal performance of your HVAC system, while providing fresh, clean air for your home or office.
