Nordic Pure MERV 12 Pleated Air Filters, 2-Pack, 20x25x4 Inches

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 it to the "Actual Size" provided, as the variance between nominal and actual size is wider for 4-inch and 5-inch air filters, depending on the manufacturer. For instance, 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).

Nordic Pure's 20x25x4 Pleated Air Filters, rated MERV 12, are made of electrostatically charged synthetic materials that effectively attract and capture most airborne particulates in your home. These high-quality pleated air filters feature a heavy-duty, moisture-resistant beverage board frame with a metal mesh support grid bonded to the pleats for extra durability. The MERV 12 rating of these furnace air filters is comparable to HVAC filters with an MPR rating of 1500-1900, ensuring efficient operation of your air conditioning and heating systems, thereby saving on utility costs and maintenance expenses.

It is crucial to regularly change your furnace air filters, especially during any home improvements, to maintain fresh, clean air in your home or office. We recommend changing the air filter every 3-6 months to maximize efficiency and economy.

The Nordic Pure 20x25x4 MERV 12 Pleated AC Furnace Air Filters have an actual size of 19-1/2-Inch by 24-1/2-Inch with a 3-3/4-Inch depth. As mentioned earlier, it is essential to measure your filter and compare it to the "Actual Size" listed to ensure a proper fit, as the majority of filters are slightly smaller than the nominal size printed on them. This variance is particularly common with 4-inch and 5-inch filters from different HVAC manufacturers.

Nordic Pure air filters are made of an electrostatically-charged synthetic material that effectively traps airborne particulates, such as pollen, fine dust, smoke particles, airborne plant spores, bacteria, and some viruses, to protect your family's health. These filters do not kill germs; however, the filter media does not allow the growth of bacteria or mold, eliminating the need for potentially irritating chemicals.

Nominal Size: 20 x 25 x 4, Actual Size: 19 1/2 x 24 1/2 x 3 5/8 (19.5 x 24.5 x 3.63) Measure your air filter for the exact size and compare it to our actual size to ensure proper fit. Made with MERV-rated synthetic poly blend pleated media. If you are replacing a Honeywell or Lennox 20x25x4 or an air filter with an MPR rating with an actual depth of 4 3/8, please see our 20x25x5 (4 3/8 actual depth) option. Nordic Pure MERV 12 is equivalent to MPR 1500-1900. Made in the USA.
