You may not have known that such a part existed in your vehicle, much less if it even needs to be changed. But still, a cabin air filter is an essential part of your car's ventilation system that removes pollutants from the air before they get inside the passenger compartment.
Cabin air filters are typically located under a vehicle's dashboard or attached to the glove box. Others may be located in the engine compartment. In nearly all cases cabin air filters can be changed in as little as 10 minutes! Cabin air filters should be changed every 12,000 to 15,000 miles.
