Ecco Manufacturing 599490 Filter Base 20x20 Inch

Product Description

The ECCO MANUFACTURING 599490 is a filter base designed for use in residential HVAC air filtration systems. It accepts a 20 x 20 inch filter and measures 22 inches in length, 21 inches in width, and 4 inches in height. The base incorporates a leaf spring design that holds the filter securely in place and a neoprene gasket along the base perimeter that seals against air bypass. Finger notches built into the housing allow for quick filter removal and replacement without tools. HVAC technicians and installers rely on this type of component for clean, reliable filter retention in air handler and furnace applications.

This filter base is suited for residential forced-air HVAC installations where a 20 x 20 inch filter is specified. The leaf spring mechanism maintains consistent filter contact against the gasket seal, reducing unfiltered air from passing around the media. The neoprene gasket construction holds up to repeated filter change cycles and helps maintain system efficiency between service visits. It is a practical fit for both new installations and retrofit applications where a dedicated filter base is needed in the return air path.

Compatibility

Designed as an OEM-style replacement or new-installation filter base for residential forced-air HVAC systems using 20 x 20 inch filters in the return air section.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power down the air handler or furnace at the disconnect and thermostat before beginning work. Ensure the filter base is secured squarely in the return air opening so the neoprene gasket seats evenly and prevents air bypass. Verify the leaf spring tension properly retains the filter before restoring system power.
