Nordic Pure MERV 12 Air Filters (16x25x4) 2 Pack

Almost all furnace filters have a different "actual size" than the nominal size printed on the air filter. It is best to measure your air filter for the exact size and compare it to the "Actual Size" provided. Regarding the 4" and 5" air filters, there is a wider variance between the nominal and actual size depending on the manufacturer. For instance, if you are replacing a 4 3/8 depth 16x25x4 filter in your Honeywell unit, you should order the 16x25x5 Honeywell Replacement air filter that measures 15 3/4 x 24 3/4 x 4 3/8 (15.75x24.75x4.38).

The Nordic Pure 16x25x4 Pleated Air Filters MERV 12 are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. All Nordic Pure pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame, and a metal mesh support grid bonded to the pleats for extra support. MERV 12 furnace air filters are comparable to HVAC filters with the rating of MPR 1500-1900. This high-performance HVAC replacement filter will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance.

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. We recommend changing your air filter every 3-6 months to maintain maximum efficiency and economy. The Nordic Pure 16x25x4 MERV 12 Pleated AC Furnace Air Filters have an actual size of 15-1/2-Inch by 24-1/2-Inch by 3-3/4-Inch.

Changing your air filter is the first step in ensuring your HVAC system runs at its optimal level this season. Generally, you should change your 4-Inch air filters every 3 to 6 months. Particles in indoor air are measured in microns, which are 1/1000 of a millimeter. A human hair is about 100 microns wide, but a Nordic Pure air filter can capture airborne particles as small as 0.3 microns.

Nordic Pure air filters do not kill germs; however, 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. Nordic Pure air filters are made out of an electro statically-charged synthetic material that draws airborne particulates to it like a magnet. Electrostatic filters help trap airborne particles to protect your family from allergy-causing pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses.

The nominal size of the Nordic Pure air 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 essential to measure your air filter for the exact size and compare it to the actual size to ensure proper fit. If you are replacing a Honeywell or Lennox 16x25x4 or an air filter with an MPR rating with an actual depth of 4 3/8, please see our 16x25x5 (4 3/8 actual depth) option. Nordic Pure MERV 12 is equivalent to MPR 1500-1900, and these filters are made in the USA, using hypoallergenic, antimicrobial, and electrostatic filter media.
