The cabin filter cleans the air that comes into your vehicle through the heating and AC vents, trapping dust, pollen, and other particles. When it gets clogged, you may notice weak airflow, bad odors, or more dust inside the car. Replacing it regularly keeps your cabin air fresh and your HVAC system working efficiently.

A clogged cabin filter reduces airflow, lets in bad odors, and makes your HVAC system work harder. Over time this can strain the blower motor and lower the air quality inside your vehicle.
