Nordic Pure 20x25x5LXREDM8-2 Merv 8 Air Filter 2 Pack

Product Description

The NORDIC PURE 20x25x5LXREDM8-2 is a MERV 8 pleated air filter designed as a direct replacement for Lennox X6673 and X6675 media filters. Sold as a 2-pack, these filters ship with a nominal size of 20x25x5 and an actual size of 19.75 x 24.75 x 4.38 inches. The filter media is hypoallergenic, antimicrobial, and electrostatic, capturing lint, household dust, pollen, pet dander, dust mites, bacteria, and mold spores on each pass. A heavy-duty, moisture-resistant beverage board frame and a bonded metal mesh support grid hold the pleats rigid under airflow. MERV 8 performance is equivalent to MPR 800, outperforming standard fiberglass and poly disposable filters.

These filters are intended for residential and light-commercial forced-air HVAC systems that accept a nominal 20x25x5 deep-media cartridge. The primary application is whole-home air filtration in systems originally equipped with Lennox X6673 or X6675 media filters. The same actual dimensions also make them compatible with Honeywell, Carrier, and Bryant systems that use this filter housing size. Installers should always verify the actual filter housing depth before ordering, as nominal and actual sizes vary across manufacturers. Recommended replacement interval is every 3 to 6 months depending on indoor conditions, occupancy, and the presence of pets or renovation activity.

Compatibility

Designed as a direct replacement for Lennox X6673 and X6675 media air filters. Also fits Honeywell, Carrier, and Bryant systems that use a nominal 20x25x5 filter housing. Always measure the actual housing depth before ordering, as actual sizes vary by manufacturer and model.

Installation Notes

Filter replacement on deep-media systems is typically performed by HVAC technicians or qualified maintenance personnel. Always shut down the air handler or furnace at the disconnect or thermostat before opening the filter cabinet. Confirm airflow direction arrows on the filter frame align with system airflow before seating the cartridge. Dispose of the used filter in a sealed bag to contain captured particulates.
