Nordic Pure 20x25x5LXREDPM12C-4 Merv 12 Carbon Filter 4 Pack

Product Description

The NORDIC PURE 20x25x5LXREDPM12C-4 is a MERV 12 pleated air filter with an activated carbon layer, sold in a 4-pack. The dual-layer media bonds a MERV 12 filtration layer with activated carbon to reduce airborne particulates and control odors simultaneously. The carbon layer targets volatile organic compounds (VOCs), odorous gases, and vapors while maintaining low flow restriction. The actual size is 19.75 x 24.75 x 4.375 inches, fitting housing units labeled as 20x25x5 nominal. This filter is manufactured in the USA with a moisture-resistant beverage board frame and an internal metal mesh support grid. Licensed HVAC technicians and qualified service professionals handle installation in forced-air systems.

This filter is designed for use in residential and light-commercial forced-air HVAC systems that accept a nominal 20x25x5 filter. It is a direct replacement for the Lennox X6673 and X6675 media air filters and is also compatible with Honeywell, Carrier, and Bryant systems using the same nominal size. The filter media is hypoallergenic, antimicrobial, and electrostatic, making it well suited for environments with allergy or odor concerns. Nordic Pure recommends replacing this filter every 3 to 6 months under typical operating conditions, though heavily used systems or dusty environments may require more frequent changes.

Key Features

• MERV 12 filtration captures lint, dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, and other fine particulates
• Activated carbon layer adsorbs VOCs, odorous gases, and vapors for fresher indoor air
• Dual-layer construction provides 33 percent more surface area and reduced airflow restriction compared to single-layer designs
• Hypoallergenic, antimicrobial, and electrostatic filter media inhibits bacterial and mold growth on the media surface
• Heavy-duty, moisture-resistant beverage board frame with bonded metal mesh support grid for structural integrity
• Made in the USA; MERV 12 rating is equivalent to MPR 1500-1900

Compatibility

Made as a direct OEM-style replacement for Lennox X6673 and X6675 media air filters. Also fits Honeywell, Carrier, and Bryant forced-air systems accepting a nominal 20x25x5 filter with an actual size of 19.75 x 24.75 x 4.375 inches. Always verify the actual housing dimensions before ordering, as nominal and actual sizes vary by manufacturer.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified service professional. Power down the air handler or furnace at the disconnect or breaker before removing the existing filter. Confirm the airflow direction arrow on the new filter frame aligns with the direction of air travel toward the blower. Follow local mechanical codes and the equipment manufacturer guidelines for filter replacement intervals and housing specifications.
