The Bard 131-131-4 is an OEM filter rack left side assembly used in select Bard wall-mount HVAC units to properly support and position the air filter so return air is directed through the filter before it reaches the blower and coil. A damaged or missing rack can let filters shift or bypass, which can lead to airflow problems, dirt buildup on internal components, and frequent service calls. Replacing the Bard 131-131-4 helps restore correct filter fit and sealing in the filter track for dependable filtration and stable system performance; confirm left-hand orientation and verify part compatibility with your specific Bard model and serial number before ordering.
* Orders less than $50 may incure a minimum order fee.
