Pro-source PRO17320251 Air Filter Frame 20x25x1 Galvanized

Product Description

The PRO-SOURCE PRO17320251 is a galvanized steel air filter frame designed to hold standard 1-inch disposable or media filters in residential and light commercial HVAC systems. Measuring 20 inches tall by 25 inches wide by 1 inch deep, this frame provides a rigid, corrosion-resistant housing that keeps filters seated squarely in the airstream. The galvanized steel construction resists moisture and the minor condensation common in air handling equipment. HVAC technicians and facilities maintenance personnel install these frames as permanent filter-holding solutions in air handlers, furnace filter racks, and return-air grille assemblies where a durable, reusable frame is preferred over a disposable cardboard border.

This filter frame is suited for residential forced-air systems and light commercial air handling units that accept 20-inch by 25-inch by 1-inch filters. It is appropriate for installations where the existing filter track does not provide adequate support or where a metal frame is required to meet local mechanical code or facility standards. The 20 x 25 x 1 nominal size is one of the most common filter dimensions in residential HVAC, making this frame a practical stock item for service fleets and maintenance departments.

Key Features

• Galvanized steel construction resists corrosion and holds shape under continuous airflow
• Nominal 20 inches x 25 inches x 1 inch size fits the most widely used residential filter slot
• Rigid frame keeps filter media flush against the seating surface, reducing bypass air
• Reusable design supports repeated filter changeouts without frame replacement
• Lightweight at 2.4 pounds, simplifying handling during installation in overhead or wall-mount returns

Compatibility

Designed as an OEM-style replacement or new-installation frame for residential and light commercial HVAC systems accepting nominal 20-inch by 25-inch by 1-inch air filters.

Installation Notes

A licensed HVAC technician or qualified mechanical contractor should install or retrofit filter frames in ducted air systems. Always set the system to the off position and verify the air handler is de-energized before accessing the filter rack or return-air plenum. Ensure the frame seats flush with no gaps at the perimeter to prevent unfiltered bypass air. Follow local mechanical codes and the equipment manufacturer's instructions for filter access panel fastening.
