- Use the car interior vacuum with crevice tool to remove dust from the filter slot and surrounding tray.
- Blow compressed air from the clean side toward the dirty side to lift embedded particles (do this outdoors or in a well-ventilated area).
- Wipe the filter housing with a damp cloth, then allow it to dry if needed before reinserting the filter.
- If the filter shows signs of heavy contamination, replace it with a new one rather than attempting a deep clean.
- Reinstall the cabin filter, ensuring the airflow direction arrows on the filter align correctly with the housing.
- Reattach the housing cover, run the HVAC on fresh air, and inspect for unusual odors or reduced airflow.
- For persistent odors, run the HVAC on high with the recirculation mode off for several minutes to vent the system.
- Document the maintenance in your vehicle records and schedule a routine replacement interval based on driving conditions.
