Cabin Air Filter Inspection and Replacement Checklist

This cabin air filter inspection and replacement checklist ensures proper cabin air filtration for passenger comfort and health. Cabin air filters trap pollen, dust, smog, and pollutants before they enter the passenger compartment through the HVAC system. Clogged filters reduce airflow, decrease A/C and heater performance, and allow contaminants into the cabin. Typical replacement interval: 12,000-15,000 miles or annually.
