Now-a-days almost all automobile manufacturers provide cabin air filters in their cars as part of the ventilation system to remove organic pollutants and malodorous compounds. These are placed in the path of outside air intake before air conditioning or ventilation system. The purpose of cabin air filters is to purify outside air entering into the vehicle.  Typically, these cabin air filters have a non-woven filter medium with an activated carbon layer.
