Glasfloss GTASP28301 Standard Air Filter 28x30x1

Product Description

The GLASFLOSS GTASP28301 is a standard 1-inch disposable air filter measuring 28 inches by 30 inches by 1 inch. Designed for use in residential and light commercial HVAC systems, it installs in the return air grille or filter rack to capture airborne dust, lint, and particulates before they reach the blower and heat exchanger. This filter is a straightforward panel-style replacement suitable for forced-air heating and cooling systems. HVAC technicians and service pros use it as a routine maintenance item during seasonal tune-ups or scheduled filter change intervals.

The GTASP28301 fits systems that require a 28 by 30 by 1 inch filter slot. This size is commonly found in residential forced-air air handlers and furnaces with larger return openings. It is appropriate for standard filter rack installations where a flat panel filter is specified. Install it in systems that do not require high-MERV or electrostatic media where basic filtration is the design intent.

• Nominal size of 28 inches by 30 inches by 1 inch fits standard large-opening filter racks

Compatibility

Installation Notes

A licensed HVAC technician or qualified service pro should power down the air handler or furnace at the disconnect before replacing the filter. Confirm airflow direction arrows on the filter frame align with the system airflow direction before seating the filter in the rack. Ensure the filter frame seats flush with no gaps around the edges that would allow unfiltered air bypass. Follow local maintenance codes and manufacturer service intervals for filter replacement frequency.
