The NORDIC PURE 20x25x5LXREDPM12C-2 is a MERV 12 Pleated Plus Carbon air filter sold in a 2-pack, designed for residential and light commercial forced-air HVAC systems. The filter uses a dual-layer media construction that fuses a MERV 12-rated pleated layer with an activated carbon layer. This design provides 33% more surface area than a standard pleated filter and reduces flow restriction while simultaneously capturing particulates and adsorbing odorous gases and volatile organic compounds (VOCs). The nominal size is 20x25x5 with an actual size of 19.75 x 24.75 x 4.375 inches. Licensed HVAC technicians and qualified service professionals typically handle installation in media cabinet housings.
This filter is sized for media filter cabinets that accept a nominal 20x25x5 filter, specifically as a direct replacement for the Lennox X6673 and X6675 media air filters. It is also compatible with same-size housings used by Honeywell, Carrier, and Bryant systems. The activated carbon layer addresses odor control alongside the standard particulate-capture function, making it well suited for occupied spaces with pets, renovation activity, or elevated indoor air quality demands. Nordic Pure recommends replacing this filter every 3 to 6 months depending on environmental conditions.
Designed as a direct replacement for Lennox X6673 and X6675 media air filters. Also fits same-size media cabinet housings used in Honeywell, Carrier, and Bryant forced-air systems that accept a nominal 20x25x5 filter with an actual depth of approximately 4.375 inches. Always verify the actual filter cavity dimensions before ordering, as nominal and actual sizes vary by manufacturer and housing model.
Installation is performed by a licensed HVAC technician or qualified service professional. Power down the air handler or furnace at the disconnect or breaker before opening the media cabinet. Confirm the actual cavity dimensions match the filter actual size of 19.75 x 24.75 x 4.375 inches before inserting the filter, and ensure the airflow arrow on the filter frame points toward the blower. Reinstall the cabinet door and restore power only after the filter is fully seated and the cabinet is secured.
