Glasfloss GDS_20X25X2 Fiberglass Panel Filter 20x25x2

Product Description

The GLASFLOSS GDS_20X25X2 is a disposable fiberglass panel air filter sized at 20 inches wide by 25 inches tall by 2 inches deep, designed for forced-air HVAC systems in commercial, industrial, and residential applications. The filter uses progressively dense fiberglass media thermally bonded to a heavy-duty one-piece craft-board frame, providing 3.47 square feet of media area. Airflow is rated at 500 FPM with an initial resistance of 0.28 inches WC and a final resistance of 0.50 inches WC. The reinforced double-strut frame construction delivers 10% greater open media area than traditional metal grill filters and is rated to 180 degrees F. Licensed HVAC technicians and building maintenance professionals are the primary installers.

This panel filter suits a wide range of forced-air systems where a 20 by 25 by 2 inch filter slot is specified. It is appropriate for light commercial air handling units, industrial ventilation systems, and residential furnace or air handler applications. The one-piece craft-board frame eliminates sharp edges for safer handling during filter changes and allows for easier disposal without disassembly. The design also reduces carton weight compared to metal-frame alternatives, making storage and job-site transport more practical for service technicians managing multiple units.
