The cabin air filter is a small screen inside your car that catches dirt and pollen from the outside before it blows into the seats. Replacing it keeps the air inside your car fresh and can help people with allergies breathe easier.

The cabin air filter cleans the air that enters the vehicle’s interior through the heating, ventilation, and air conditioning (HVAC) system. It traps dust, pollen, and other pollutants to keep the cabin environment clean and improve air quality for occupants.
