The AMERICAN METAL PRODUCTS 326W20X25 is a steel lanced return air filter grille designed for residential and light commercial HVAC systems. Measuring 20 inches by 25 inches with a white finish, it accepts standard 1-inch disposable filters and effectively conceals them behind a clean face panel. The grille features fins spaced at 1/2 inch and set at a 40-degree angle to promote consistent airflow while maintaining an unobtrusive appearance. A removable face panel simplifies filter changes and routine cleaning. Adjustable filter retainers secure the filter in place without tools. Licensed HVAC technicians and sheet metal contractors are the typical installers for this product.
This grille is suited for wall or ceiling return air applications in residential and light commercial settings. It is commonly installed in new construction and retrofit projects where a clean, finished look is required at the return air opening. The all-steel construction holds up in high-traffic areas and stands up to repeated filter service cycles. Filters are not included and must be sourced separately; standard 1-inch thick disposable filters are the correct size for this grille.
Designed as an OEM-style replacement or new-installation return air filter grille for residential and light commercial HVAC duct systems requiring a 20-inch by 25-inch return air opening with standard 1-inch filter compatibility.
Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler or furnace at the disconnect before beginning work. The removable face panel should be detached prior to securing the grille frame to the duct or wall opening to allow clear access to mounting points. Verify the rough opening dimensions match the grille face size before fastening.
