Nordic Pure 20x25x5ABM12-4 Merv 12 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x25x5ABM12-4 is a MERV 12 pleated replacement air filter designed to fit Trion Air Bear filter housings. Sold in a 4-pack, each filter has a nominal size of 20x25x5 and an actual size of 19.75 x 24.25 x 4.875 inches. The filter media is hypoallergenic, antimicrobial, and electrostatic, capturing lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, and other airborne contaminants. The heavy-duty frame is constructed from moisture-resistant beverage board and includes two foam tape strips on two sides. A metal mesh support grid is bonded to the pleats for added structural rigidity. Licensed HVAC technicians and qualified residential service professionals typically install this filter.

This filter is engineered as a direct replacement for Trion Air Bear deep-media filter housings that accept a 4 7/8 inch depth filter. It is suited for residential forced-air heating and cooling systems where high-efficiency filtration is required, including households with occupants who have moderate allergy concerns. The 259112-102 is the OEM part number this filter is designed to replace. Verify the actual dimensions of your existing filter before ordering, as nominal and actual sizes often differ depending on the original equipment manufacturer.

Installation Notes

Installation is typically performed by a licensed HVAC technician or a qualified service professional familiar with forced-air system maintenance.

Nordic Pure recommends replacing this filter every 3 to 6 months, though actual service life varies based on indoor and outdoor air quality conditions.
