A cabin filter is an important component of a vehicle’s ventilation system that helps improve the air quality inside the passenger compartment. It filters out dust, pollen, pollutants and other airborne particles from the outside air before it enters the cabin through the heating, ventilation and air conditioning (HVAC) system. By trapping these contaminants, the cabin filter ensures cleaner, fresher air for the driver and passengers, which is especially beneficial for those with allergies or respiratory conditions. Over time, the cabin filter can become clogged with dirt and debris, reducing airflow and the effectiveness of the HVAC system. Regular replacement of the cabin filter is recommended to maintain optimal air quality, proper ventilation and overall comfort inside the vehicle.
