This cab filter is the original AGCO component that cleans the air entering the tractor cabin. It captures dust and pollen before the air reaches the HVAC evaporator and the operator’s breathing zone. A clogged filter reduces airflow, leading to poor defogging performance and increased fan noise. The filter’s pleated media is sized to match the factory housing’s sealing surfaces, so unfiltered air cannot bypass the element. When replacing, remove any debris from the housing tray and seat the filter fully against the gasket.
