Nordic Pure 20x20x5ABM8-1 Merv 8 Air Filter 1 Pack

Product Description

The NORDIC PURE 20x20x5ABM8-1 is a MERV 8 pleated air filter designed as a direct replacement for Trion Air Bear filter systems. It measures 19.69 x 20.69 x 4.94 inches actual size, fitting the standard 20x20x5 nominal slot with a depth of 4 15/16 inches. The filter uses hypoallergenic, antimicrobial, electrostatic media to capture lint, household dust, pollen, dust mites, pet dander, bacteria, mold spores, and other airborne contaminants. A metal mesh support grid is bonded to the pleats for structural integrity. The moisture-resistant beverage board frame includes two strips of foam tape on two sides to ensure a secure, bypass-free fit. Installed by HVAC technicians and knowledgeable DIYers servicing residential forced-air systems.

This filter is suited for residential HVAC applications using Trion Air Bear media cabinets that accept a 20x20x5 nominal filter. The actual depth of 4 15/16 inches is a critical fit dimension - manufacturers vary on actual depth across the 4-inch and 5-inch depth categories, so confirming the actual size against your cabinet is recommended before installation. At MERV 8, this filter is rated equivalent to MPR 800 and will outperform standard fiberglass, poly disposable, and non-electrostatic washable filters. Nordic Pure recommends replacing this filter every 3 to 6 months depending on indoor air quality conditions and usage.

Installation Notes

Always shut down the HVAC system at the thermostat and disconnect power at the air handler or furnace disconnect before replacing the filter. Confirm the actual cabinet opening dimensions match the filter actual size - nominal sizing alone is not sufficient for 5-inch depth cabinets due to manufacturer variance. Slide the filter into the media cabinet with the airflow arrow pointing toward the blower. Replace every 3 to 6 months or more frequently in high-dust or high-occupancy environments.
