Nordic Pure 16x25x5ABM10-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 16x25x5ABM10-4 is a MERV 10 pleated replacement air filter designed for Trion Air Bear filter housings. It ships in a 4-pack and features an actual size of 15-5/8 x 24-1/8 x 4-7/8 inches - not the nominal 16x25x5 printed on the label. The filter media is hypoallergenic, antimicrobial, and electrostatic, capable of capturing lint, household dust, pollen, dust mites, pet dander, mold spores, bacteria, and other airborne allergens. The frame is constructed from heavy-duty, moisture-resistant beverage board with foam tape strips on two sides and a metal mesh support grid bonded directly to the pleats for structural integrity.

This filter is intended for residential and light commercial forced-air HVAC systems using Trion Air Bear 5-inch deep filter cabinets. MERV 10 performance is comparable to MPR 900-1000 rated filters, placing it well above standard fiberglass, poly disposable, and washable filter options. It is suited for households with pets, allergy sufferers, or environments with higher-than-average airborne particulate loads. Installers and homeowners should verify the actual slot dimensions before ordering, as nominal sizing varies by manufacturer and housing design. Replacing filters every 3 to 6 months is recommended to maintain system airflow and filtration efficiency.

Designed as a direct replacement for Trion Air Bear filter housings requiring a 5-inch deep filter with a nominal size of 16x25x5. Replaces OEM part number 255649-105. Verify the actual slot depth in your housing before ordering, as actual depth is 4-7/8 inches.

Installation Notes

Filter replacement is typically performed by HVAC technicians or knowledgeable homeowners. Always shut down the air handler or furnace at the disconnect or thermostat before servicing the filter cabinet. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the system before seating the filter. Measure the existing filter or the housing slot to confirm actual dimensions match before installation - nominal and actual sizes differ on 5-inch deep filters.
