This cabin filter captures airborne dust, pollen, and debris before air enters the operator station. It sits in the housing that feeds the HVAC intake, maintaining a clean environment for the operator during harvest or field work. A loaded filter reduces airflow volume, which can cause the HVAC blower to run continuously at high speed without achieving the set temperature. The filter is constructed to the same pleat density and media surface area as the original assembly, so it matches the housing seal profile and does not allow unfiltered air to bypass the media.
