Bosch Cabin Filters are designed with multiple layers of protection. Bosch Activated Charcoal Cabin Air Filters have a 5-layer design that includes an additional carbon layer that absorbs toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons, and an additional cover layer for extra protection. The benefits of using a good, quality cabin filter greatly benefits the well-being of all passengers in the vehicle.
