This cabin filter panel captures airborne dust and pollen before they enter the cab ventilation system. It sits in the housing behind the cab intake grille; the pleated filter media traps particles that would otherwise circulate through the HVAC plenum and onto the operator. A loaded filter restricts airflow, causing reduced fan output and fogging on the interior glass. The manufacturer matches the housing’s seal profile so the filter seats without gaps that would bypass unfiltered air. On replacement, ensure the gasket is clean and the retaining clips engage fully.
