The NORDIC PURE 16x25x5ABM15-2 is a MERV 15 pleated air filter designed as a direct replacement for Trion Air Bear filter housings. With an actual size of 15.63 x 24.13 x 4.88 inches, this filter fits the nominal 16x25x5 slot found in many residential and light commercial HVAC systems. Each filter uses hypoallergenic, antimicrobial, and electrostatic filter media bonded to a metal mesh support grid, all housed in a moisture-resistant beverage board frame with foam tape seals on two sides. This two-pack is installed by licensed HVAC technicians or experienced service professionals maintaining high-efficiency air handling systems.
This filter is designed for use in Trion Air Bear filter housings that accept a nominal 16x25x5 filter with a depth of 4 7/8 inches. It is suitable for residential and light commercial HVAC applications where superior particulate filtration is required. Captured contaminants include airborne dust, pollen, mold spores, pet dander, smog, dust mite debris, smoke, and bacteria. It is rated equivalent to MPR 2800, making it a high-performance option for systems that demand more than standard fiberglass or poly disposable filters provide.
Designed as a replacement filter for Trion Air Bear housings requiring a nominal 16x25x5 filter with an actual depth of 4 7/8 inches. Verify your housing accepts the actual size of 15.63 x 24.13 x 4.88 inches before ordering, as nominal and actual dimensions vary by manufacturer. This filter replaces OEM part number 266649-105.
Filter replacement in Trion Air Bear housings is typically performed by a licensed HVAC technician. Power down the air handler at the disconnect or thermostat before opening the filter cabinet. Confirm airflow direction arrow on the filter frame aligns with system airflow before seating the filter. Nordic Pure recommends replacing this filter every 3 to 6 months depending on indoor air quality conditions and usage.
