The Dust and Pollen filter, also known as the cabin air filter, is a component that removes dust, pollen, and other contaminants from the air that enters the vehicle's cabin through the heating, ventilation, and air conditioning (HVAC) system. It's designed to improve the air quality inside the vehicle and protect the occupants from breathing in harmful particles.
It's important to note that cabin air filters should be replaced regularly, as per the vehicle's recommended schedule or as indicated by the vehicle's manufacturer. Neglecting to replace the filter can lead to poor air quality inside the vehicle and reduced efficiency of the HVAC system.
It's also important to use the correct type of filter for your vehicle as specified in the vehicle's manual or by the filter manufacturer.
