Nordic Pure 20x20x4M13+C-6 Merv 13 Plus Carbon Filter 6 Pack

Product Description

The NORDIC PURE 20x20x4M13+C-6 is a MERV 13 pleated air filter with an integrated activated carbon layer, sold in a 6-pack. The nominal size is 20x20x4 inches with an actual size of 19.5 x 19.5 x 3.63 inches. The filter media is electrostatically charged synthetic material bonded to a flat activated carbon panel. This combination captures airborne particulates down to 0.30 microns while the carbon layer adsorbs odors and volatile organic compounds (VOC). Licensed HVAC technicians and knowledgeable homeowners install these filters in residential forced-air heating and cooling systems. Each filter features a heavy-duty moisture-resistant beverage board frame with a metal mesh support grid bonded to the pleats for structural integrity.

This filter is designed for residential forced-air systems with a 4-inch filter track accepting a nominal 20x20x4 filter. The actual depth of 3.63 inches fits standard 4-inch filter housings from most manufacturers. Note: if you are replacing a Honeywell or Lennox 20x20x4 filter with an actual depth of 4 3/8 inches, this filter is not the correct replacement - order a 20x20x5 unit with a 4 3/8 inch actual depth instead. The 6-pack format supports a standard 3-to-6-month replacement cycle, making it practical for annual or semi-annual service stock.

• Hypoallergenic, antimicrobial, and electrostatically charged synthetic filter media
• Heavy-duty moisture-resistant beverage board frame with metal mesh pleat support grid
• Equivalent to MPR 2200-2400 rated filters
• Made in the USA

Compatibility

Fits residential forced-air HVAC systems with a standard 4-inch filter housing accepting a nominal 20x20x4 filter. Actual size is 19.5 x 19.5 x 3.63 inches. Not a direct replacement for units requiring a 4 3/8 inch actual depth filter such as certain Honeywell and Lennox 20x20x4 housings - those applications require a 20x20x5 filter with 4 3/8 inch actual depth.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified homeowners. Power down the air handler or furnace at the disconnect or thermostat before removing the old filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Nordic Pure recommends replacing this filter every 3 to 6 months, or more frequently during renovation activity or periods of high particulate load.
