The NORDIC PURE 16x25x5ABM10-2 is a MERV 10 pleated replacement air filter designed to fit Trion Air Bear filter cabinets with a nominal 16x25x5 opening. The actual dimensions are 15.63 x 24.13 x 4.88 inches, with a depth of 4.88 inches. Each filter uses hypoallergenic, antimicrobial, electrostatic media that captures lint, household dust, pollen, dust mites, pet dander, mold spores, bacteria, and other airborne particulates. The frame is constructed from moisture-resistant beverage board with two foam tape strips on two sides and a bonded metal mesh support grid for media stability. Licensed HVAC technicians and qualified service contractors install these filters in residential and light commercial forced-air systems.
These filters are sized as direct replacements for Trion Air Bear media cabinets that accept a 16x25x5 nominal filter, including units originally supplied with part number 255649-105. They are suited for residential forced-air furnace and air handler applications where deeper media filters are specified. The MERV 10 rating is equivalent to MPR 1000, making these filters a step up from standard fiberglass, poly disposable, and non-electrostatic washable filters. Each carton contains two filters. Nordic Pure recommends changing filters every 3 to 6 months under normal residential conditions, or more frequently during renovation or high-dust activity.
Designed as a direct replacement for Trion Air Bear media filter cabinets accepting a nominal 16x25x5 filter, replacing OEM part number 255649-105. Verify the actual filter slot dimensions against the actual size of 15.63 x 24.13 x 4.88 inches before ordering, as nominal and actual sizes vary by cabinet manufacturer.
Filter installation is typically performed by a licensed HVAC technician or qualified service contractor. Always shut down the furnace or air handler at the system disconnect or thermostat before opening the filter cabinet. Confirm airflow direction arrows on the filter frame align with the direction of airflow into the blower section. Measure the existing filter or the cabinet slot before ordering to verify actual size compatibility, as nominal dimensions are not interchangeable across all manufacturers.
