An outflow vent arranged inside the passenger compartment of a motor vehicle. Said vent is used to supply conditioned air by means of a fan inside said passenger compartment and contains at least one filter unit (1) for the removal of air pollutants and/or odorous and/or irritant substances from the outflowing air. One advantage of the invention is that the filter unit is interchangeable and arranged downstream from a central main filter of a heating and/or air conditioning system in the flow path of the conditioned air. Several filter units having different filtering properties can be arranged successively in the flow path of the conditioned air or a filter unit consisting of several elements having different filtering properties and which are assembled together to form a module can be provided. |
