When should these cabin air filters be replaced?

To keep the HVAC system supplying clean air, replace the cabin filter at routine intervals. Typical guidance is yearly or according to mileage, and sooner in dusty or high-pollen environments.

• Suggested replacement: every 12 months or about 12,000 miles
• Replace sooner if you notice reduced airflow, persistent odors, or visible dirt on the old filter
• Always consult the vehicle manufacturer’s maintenance schedule for exact intervals
