Glasfloss GDS_14X20X1 Fiberglass Panel Air Filter 14x20x1

Product Description

The GLASFLOSS GDS_14X20X1 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 20 inches tall by 1 inch deep, it delivers 1.94 square feet of media area with an airflow rating of 300 FPM. The filter uses progressively dense fiberglass media that is thermally bonded for consistent performance and excellent dust-holding capacity. A heavy-duty one-piece craft-board frame with reinforced double-strut construction provides rigidity throughout the filter service life. HVAC technicians and facility maintenance personnel install this filter as a standard panel replacement in air handlers, furnaces, and return-air grilles.

This filter is rated for commercial, industrial, and residential HVAC installations where a cost-effective, disposable panel filter is required. The one-piece box frame design provides 10 percent greater open media area compared to traditional metal-grill filters, which supports airflow efficiency and reduces static pressure buildup. The frameless-edge design eliminates sharp corners for safer handling during changeouts, and the lightweight craft-board construction reduces disposal weight. The 1-inch depth fits standard filter tracks sized for 14 x 20 x 1 nominal slots. This filter is rated to 180 degrees F, making it suitable for applications with elevated supply-air temperatures.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Power down the air-handling unit or furnace before removing the existing filter and installing the replacement. Confirm airflow direction arrow on the filter frame is oriented toward the blower before securing the unit access panel. Dispose of used filters in accordance with local waste guidelines; the craft-board frame requires no special handling for standard disposal.
