A cabin air filter is a filter that is placed in the air intake system of a vehicle, typically just outside the passenger compartment, and is responsible for filtering out pollen, dust, and other contaminants from the air entering the car.

This helps improve the air quality inside the vehicle, which benefits the driver and passengers.

Cabin air filters are typically made from highly absorbent materials, such as activated charcoal or paper.

They are designed to be replaced regularly to keep the air inside the car free from pollutants.
