Bard 540-189 - Filter Support

Bard part number 540-189 is an OEM filter support used in Bard wall-mount air conditioners to properly position and hold the air filter so return air is routed through the filter the way the unit was designed. A worn or damaged support can let the filter sag or shift, which can lead to air bypass, dirt buildup on the coil, and higher static pressure. Replacing the filter support helps restore correct filter fit and airflow, supports consistent system performance, and simplifies routine filter changes by keeping the filter aligned in the rack during service.
