The NORDIC PURE 16x25x5ABM12-2 is a MERV 12 pleated replacement air filter designed to fit Trion Air Bear filter housings with a nominal size of 16x25x5. The actual dimensions measure 15.63 x 24.13 x 4.88 inches, with a depth of 4.88 inches. This filter uses hypoallergenic, antimicrobial, and electrostatic filter media bonded to a metal mesh support grid for structural integrity. The moisture-resistant beverage board frame includes two strips of foam tape on two sides to seal against bypass. This pack contains two filters. Licensed HVAC technicians and service professionals install these in residential and light commercial forced-air systems.
This filter is suited for residential forced-air heating and cooling systems that use the Trion Air Bear deep-media housing accepting a nominal 16x25x5 filter. At MERV 12 efficiency, it captures lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, bacteria, and other airborne contaminants with each pass. MERV 12 performance is equivalent to MPR 1500-1900 rated filters, making it appropriate for households with moderate allergy concerns or where higher air quality is a priority. Filters should be replaced every 3 to 6 months depending on operating conditions and indoor air quality demands.
Designed as a replacement for Trion Air Bear filter housings using a nominal 16x25x5 filter with a 4.88-inch actual depth. This filter replaces OEM part number 259112-105. Verify actual filter compartment dimensions before ordering, as nominal and actual sizes vary by manufacturer and housing model.
Installation is performed by a licensed HVAC technician or qualified service professional. Always shut down the air handler or furnace at the disconnect or breaker before opening the filter housing. Confirm actual compartment dimensions match the filter before insertion, and ensure the foam tape seals contact the housing frame on all applicable sides to prevent unfiltered air bypass. Dispose of the used filter in accordance with local waste guidelines.
