The GLASFLOSS GDS_15X20X1 is a disposable fiberglass panel air filter designed for use in commercial, industrial, and residential HVAC air-handling systems. Measuring 15 inches wide by 20 inches tall by 1 inch deep, it delivers 2.08 square feet of media area at a rated airflow of 300 FPM. Initial resistance is 0.09 inches WC, with a final resistance of 0.5 inches WC. The filter uses progressively dense, thermally bonded fiberglass media housed in a heavy-duty one-piece craft-board frame. The double-strut internal frame construction adds rigidity and provides 10 percent greater open media area than traditional metal-grille filters, improving dust-holding capacity and extending service intervals.
This filter is rated for commercial, industrial, and residential HVAC applications where a low-cost, high-flow disposable panel filter is appropriate. The 1-inch depth fits standard filter slots in air handlers, furnaces, and rooftop units configured for 1-inch panel filters. The craft-board frame eliminates sharp metal edges, making changeouts safer and disposal simpler. Rated to 180 degrees F, the GDS_15X20X1 handles the elevated temperatures found in heating-season applications. It meets UL 900, HARDI, and NAFA applicable standards and is manufactured in the USA.
Designed as an OEM-style replacement panel filter for commercial, industrial, and residential HVAC systems requiring a 15-inch by 20-inch by 1-inch disposable panel filter.
Panel air filters of this type are typically installed and replaced by HVAC technicians or qualified maintenance personnel. Always power down the air-handling unit or furnace before opening the filter access panel and removing the old filter. Confirm airflow direction marked on the filter frame aligns with system airflow before securing the access door. Dispose of used filters in accordance with local waste regulations.
