Glasfloss GDS_14X25X1 Fiberglass Panel Air Filter

Product Description

The GLASFLOSS GDS_14X25X1 is a disposable fiberglass panel air filter designed for use in forced-air HVAC systems across commercial, industrial, and residential applications. Measuring 14 inches wide by 25 inches tall by 1 inch deep, it delivers an initial resistance of 0.09 inches WC and a final resistance of 0.5 inches WC at a rated airflow of 300 FPM. The heavy-duty one-piece craft-board frame uses a reinforced double-strut construction that provides superior rigidity and 10% greater open media area than traditional metal-grill filters, improving dust holding capacity while simplifying end-of-life disposal.

This filter is suited for a wide range of HVAC installations including rooftop units, air handling units, and packaged systems in light commercial and industrial settings, as well as residential furnaces and air handlers. Its progressively dense fiberglass media traps airborne particulates efficiently throughout the filter's service life. The double-strut frame eliminates sharp edges, making handling safer for technicians during changeouts, and reduces carton weight compared to metal-frame alternatives. It is manufactured in the USA and carries an Energy Star rating.

Installation Notes

Installation is performed by HVAC technicians or qualified service professionals. Always shut down the air handler or furnace and set the thermostat to the off position before removing the existing filter.
