The NORDIC PURE 16x25x5ABPM12C-2 is a MERV 12 pleated plus carbon replacement air filter designed for deep-media filter housings that accept a 4 7/8-inch depth cartridge. The filter combines a MERV 12-rated pleated media layer with an activated carbon layer fused together into a single media pack. This dual-layer construction reduces airflow restriction while adding 33% more surface area compared to standard pleated media. The activated carbon layer adsorbs odorous gases and volatile organic compounds (VOCs), while the pleated MERV 12 media captures lint, dust, pollen, dust mites, pet dander, mold spores, bacteria, and other particulates. Sold as a 2-pack. Licensed HVAC technicians and experienced DIYers typically handle this replacement.
This filter is engineered as a replacement for Trion Air Bear and comparable deep-media filter housings that use a nominal 16x25x5 cartridge with an actual depth of 4 7/8 inches. It is suited for residential and light-commercial forced-air heating and cooling systems where both particulate removal and odor control are priorities. The antimicrobial, electrostatic filter media helps inhibit bacteria and mold growth within the media itself. The heavy-duty moisture-resistant beverage board frame includes two strips of foam tape on two sides and a metal mesh support grid bonded to the pleats for structural rigidity under continuous airflow.
Designed as a replacement for Trion Air Bear filter housings and other deep-media systems accepting a nominal 16x25x5 cartridge with an actual depth of 4 7/8 inches. Always verify the actual size of your existing cartridge before ordering, as actual dimensions vary by housing manufacturer. Actual size of this filter is 15 5/8 inches x 24 1/8 inches x 4 7/8 inches (15.63 x 24.13 x 4.88 inches).
Power down or set the thermostat to the off position before opening the filter housing. Confirm actual cartridge dimensions against the filter housing slot before installing - nominal sizing on deep-media filters frequently differs from actual dimensions by a meaningful amount. Reinstall the housing cover securely and restore system power. Filter replacement is recommended every 3 to 6 months depending on indoor air quality conditions and system runtime.
