Westinghouse 918397 Media Filter 20x25 in Merv 11

Product Description

The WESTINGHOUSE 918397 is a right-angle media replacement filter rated MERV 11, designed for residential and light-commercial forced-air HVAC systems. It captures airborne particulates including dust, pollen, mold spores, and fine debris at an efficiency level that balances filtration performance with adequate airflow. The 20 x 25 inch face dimensions and right-angle configuration make it a direct fit for specific filter housings and media cabinets. HVAC technicians and experienced service professionals handle installation during routine maintenance or system upgrades.

This filter is suited for residential gas or electric forced-air systems and light-commercial applications where improved indoor air quality is a priority without restricting system airflow below design parameters. The right-angle design is specific to media cabinet housings that require an angled filter orientation rather than a standard flat-load configuration. Verify housing dimensions and entry angle before ordering.

Key Features

• MERV 11 filtration rating captures dust, pollen, mold spores, and fine particulates
• Right-angle media configuration for compatible cabinet-style filter housings
• 20 x 25 inch face dimensions for a precise housing fit

Compatibility

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified service professional. Power down the air handler or furnace at the disconnect or breaker before accessing the filter cabinet.
