What Is The Cabin Filter

The cabin filter is a small pleated filter made of multi-fiber paper cotton or other engineering materials. Before entering the passenger compartment, outside air is directed through this filter to capture the contaminants in the filter and prevent them from entering the interior of your vehicle. Clean air is essential to the normal operation of the vehicle; your car’s engine air filter ensures that clean air enters the engine. Similarly, the ventilation system of your car relies on the air filter in the car to maintain a steady flow of clean air.
