Nordic Pure Air Filters, MERV 12, 2-Pack

It's crucial to note that almost all furnace filters have an "actual size" that differs from the nominal size printed on the air filter. Therefore, it's best to measure your air filter to determine the EXACT size and compare it to our "Actual Size" specifications. This is particularly important for 4" and 5" air filters, as there can be a wider variance between the nominal and actual size depending on the manufacturer. For instance, if you're replacing a 4 3/8 depth 16x25x4 filter in your Honeywell unit, you should order our 16x25x5 Honeywell Replacement air filter that measures 15 3/4 x 24 3/4 x 4 3/8 (15.75x24.75x4.38).

Nordic Pure 16x25x4 Pleated Air Filters MERV 12 are manufactured using electrostatically charged synthetic materials that effectively attract and capture most airborne particulates in your home. All Nordic Pure pleated air filters feature a heavy-duty, moisture-resistant beverage board frame, with a metal mesh support grid bonded to the pleats for extra reinforcement.

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

Particles in indoor air are measured in microns, which are 1/1000 of a millimeter. For reference, a human hair is approximately 100 microns wide. Nordic Pure air filters are designed to capture airborne particles as small as 0.3 microns, making them highly effective in trapping allergens such as pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

It's important to note that Nordic Pure air filters do not kill germs; however, the filter media does not allow the growth of bacteria or mold. As a result, it is unnecessary to add any potentially irritating chemicals to the air filter to kill germs.

Nordic Pure air filters are made of an electrostatically charged synthetic material that attracts airborne particulates, acting like a magnet. This electrostatic filtration process helps trap these particles, protecting your family from allergy-causing pollutants.

The Nominal Size of these filters is 16 x 25 x 4, with an Actual Size of 15 1/2 x 24 1/2 x 3 5/8 (15.5 x 24.5 x 3.63). It is crucial to measure your air filter and compare it to our Actual Size to ensure a proper fit.

If you are replacing a Honeywell or Lennox 16x25x4 filter or an air filter with an MPR rating and an actual depth of 4 3/8, please consider our 16x25x5 (4 3/8 actual depth) option.

Nordic Pure MERV 12 filters are equivalent to MPR 1500-1900 and are made in the USA. They are hypoallergenic, antimicrobial, and feature electrostatic filter media.
