Glasfloss gds12121 Fiberglass Disposable Panel Filter

Product Description

The GLASFLOSS gds12121 is a fiberglass disposable panel filter built with a reinforced double strut construction for use in commercial, industrial, and residential HVAC applications. The double strut frame design delivers 10% greater open media area compared to traditional metal grill filters, improving airflow while maintaining strong dust holding capacity. Progressively dense fiberglass media captures particulates effectively across the filter depth. The media and strut retainers are glued and sealed inside a one-piece craftboard frame made from 100% recycled materials. HVAC technicians and facility maintenance personnel install this filter as a routine replacement in forced-air systems.

This filter is suited for residential return air grills, commercial air handlers, and light industrial HVAC systems requiring a standard 12 inches x 12 inches x 1 inch panel filter. The one-piece craftboard frame eliminates sharp edges for safer handling during changeout, and the frame is clearly marked with size, classification, and airflow direction to simplify correct installation. The GDS Series is designed to fit most standard filter tracks and return air grills where a 1 inch depth panel filter is specified.
