Glasfloss GDS_20X24X2 Panel Air Filter 20x24x2 in

Product Description

The GLASFLOSS GDS_20X24X2 is a disposable panel air filter designed for forced-air HVAC systems in commercial, industrial, and residential applications. It measures 20 x 24 x 2 inches and uses progressively dense fiberglass media bonded into a heavy-duty one-piece craft-board frame. Initial resistance is 0.28 inches WC with a final resistance rating of 0.50 inches WC, and airflow capacity is rated at 500 FPM across 3.33 square feet of media area. The reinforced double-strut frame construction delivers greater structural integrity than traditional metal-grill-style filters, making it a reliable choice for high-cycle commercial air handling units as well as standard residential furnaces and air handlers. Licensed HVAC technicians and facility maintenance professionals are the primary installers.

This filter fits into standard filter tracks on rooftop units, air handling units, fan coil units, and residential furnaces wherever a 20 x 24 x 2 inch filter slot is specified. The progressively dense fiberglass media captures dust and particulates efficiently while maintaining low static pressure drop across the filter face. The design provides 10 percent greater open media area than traditional metal-grill filters, which supports better airflow balance in systems with tight static pressure budgets. The one-piece craft-board frame eliminates sharp metal edges, allowing safer handling during replacement and easier disposal at end of service life.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Always shut down the air handling unit or furnace at the disconnect or thermostat before removing the old filter to avoid unfiltered air bypass. Verify airflow direction markings on the filter frame and align with the system airflow arrow before seating the filter fully into the track. Follow local codes and the equipment manufacturer's recommended filter change intervals based on measured final resistance or scheduled maintenance.
