Nordic Pure 20x20x5ABM10-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x20x5ABM10-4 is a MERV 10 pleated air filter designed as a direct replacement for Trion Air Bear filter systems. Sold in a 4-pack, each filter has a nominal size of 20x20x5 and an actual size of 19.69 x 20.69 x 4.94 inches, with an actual depth of 4 15/16 inches. The filter media is hypoallergenic, antimicrobial, and electrostatic, bonded to a metal mesh support grid for structural integrity. The frame is constructed from moisture-resistant beverage board and includes two foam tape strips on two sides for a secure, sealed fit. Licensed HVAC technicians and plumbers installing whole-home filtration systems rely on accurate actual dimensions to ensure proper fitment.

This filter is designed for use with Trion Air Bear whole-house air filtration systems, which are commonly installed inline with residential forced-air furnaces and air handlers. The 4 15/16 inch actual depth fits the Air Bear media cabinet and is appropriate for normal residential air filtration applications. A 4-pack supply supports a standard 12-to-24-month service rotation when filters are changed every 3 to 6 months, which is the recommended interval for maintaining system efficiency, especially during periods of home renovation or high-particulate activity.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified service professional. Shut down the furnace or air handler at the disconnect or thermostat before opening the filter cabinet. Confirm the actual size of the replacement filter matches the cabinet slot dimensions before inserting.
