Nordic Pure 20x25x5ABM8-4 Merv 8 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x25x5ABM8-4 is a MERV 8 pleated replacement air filter designed for Trion Air Bear filter systems. 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, pet dander, dust mites, bacteria, mold spores, and other airborne contaminants. The heavy-duty frame is made from moisture-resistant beverage board with two foam tape strips on two sides. A metal mesh support grid is bonded to the pleats for structural integrity. Licensed HVAC technicians and experienced service professionals install these filters as part of routine preventive maintenance.

This filter is a direct replacement for Trion Air Bear media cabinets that accept a 20x25x5 filter with a 4 7/8 inch actual depth. It is rated MERV 8, equivalent to MPR 800, making it a step up from standard fiberglass, poly disposable, and non-electrostatic washable filters. Typical applications include residential forced-air heating and cooling systems where the Air Bear media cabinet is installed. Replacing the filter every 3 to 6 months helps maintain airflow efficiency and reduces strain on the blower and heat exchanger. The filter also carries part number compatibility with Trion replacement reference 255649-102.

Always verify the actual cabinet depth before ordering, as nominal and actual filter dimensions can vary by manufacturer.

Installation Notes

Installation is performed by a qualified HVAC technician or experienced service professional. Always shut down the furnace or air handler at the disconnect or breaker before opening the filter cabinet. Confirm the actual slot dimensions of the media cabinet match the filter actual size of 19.75 x 24.25 x 4.875 inches before installing. Ensure the foam tape strips seat flush against the cabinet frame to prevent air bypass around the filter.
