The Glasfloss GDS 19-7/8×21-1/2×1 disposable air filter features a strong double-strut design, providing excellent durability and performance for homes, businesses, and industrial settings. It offers 10% more open media area than traditional filters, enhancing its dust-holding capacity. We designed this filter for easy disposal and safe handling, eliminating sharp edges. The progressively dense fiberglass maximizes dust trapping. The frame, made from 100% recycled materials, clearly shows size, U.L. classification, and airflow direction. We use an adhesive that is non-toxic, non-flammable, and odor-free to bond all parts, ensuring safety and reliability.
