Koch Filter 20X25X1NM Air Filter 20x25x1 Non-metal Frame

Product Description

The KOCH FILTER 20X25X1NM is a disposable air filter built with a non-metal frame, sized at 20 inches by 25 inches by 1 inch. It is designed for forced-air HVAC systems that require standard panel filtration in residential or light commercial applications. The non-metal frame construction makes disposal straightforward and reduces the risk of corrosion in humid environments. This filter captures airborne dust, lint, and larger particulate matter while maintaining adequate airflow through the air handler or furnace. HVAC technicians and facilities maintenance staff install this filter as part of routine preventive maintenance schedules.

This filter fits standard 20 x 25 x 1 inch filter slots found in residential furnaces, air handlers, and return-air grilles. It is suited for applications where frequent filter changes are part of a regular maintenance program. The non-metal frame design is compatible with systems where metal components in the filter track could cause fit or corrosion concerns. Installations in both residential and light commercial settings are typical for this size and style.

Installation Notes

Filter installation should be performed by a qualified HVAC technician or a knowledgeable maintenance professional. Power down the air handler or furnace at the disconnect before opening the filter access panel. Confirm airflow direction arrows on the filter frame align with system airflow toward the blower. Do not operate the system without a filter in place, as doing so can damage the blower and coil.
