The NORDIC PURE 16x25x5ABM12-1 is a MERV 12 pleated replacement air filter designed to fit Trion Air Bear media cabinets that accept a nominal 16x25x5 filter. The actual dimensions are 15.63 x 24.13 x 4.88 inches, with a depth of 4 7/8 inches. The 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 gaskets on two sides. MERV 12 filtration captures lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, and other airborne contaminants. Licensed HVAC technicians and experienced DIYers install this filter as a direct drop-in service replacement.
This filter is sized for Trion Air Bear media filter cabinets calling for a nominal 16x25x5 replacement. It is appropriate for residential forced-air heating and cooling systems where high-efficiency filtration is required, including households with moderate allergy concerns. The MERV 12 rating is equivalent to MPR 1500-1900, placing it well above standard fiberglass, poly disposable, and washable filter options in particle capture efficiency. A change interval of every 3 to 6 months is typical under normal residential conditions, though higher-dust environments or active home improvement work may shorten that interval.
Designed as a direct replacement for Trion Air Bear media filter cabinets using a nominal 16x25x5 filter with a 4 7/8 inch depth. Replaces OEM part number 259112-105. Always verify actual cabinet dimensions before installation, as nominal and actual filter sizes vary by manufacturer.
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 removing the existing media filter. Note airflow direction arrows on the filter frame and orient the replacement filter accordingly. Confirm the actual filter dimensions match the cabinet opening before closing and latching the media cabinet door.
