DEVICE FOR IMPROVING INTERIOR AIR QUALITY IN A VEHICLE AND A VEHICLE

A device for improving an interior air quality in a vehicle includes a photoreactor and a control device. The photoreactor is connectable, by a photoreactor line section, between a fresh air intake and an air distribution system of a ventilation system and/or air conditioning system of the vehicle. The photoreactor line section has a controllable valve in each of the two end regions, i.e., at the respective points at which it is connectable on the one hand to the fresh air intake and on the other hand to the air distribution system. The photoreactor has UV-C LEDs that emit UV-C radiation. The control device controls the air passing through the photoreactor using the controllable valves arranged in the photoreactor line section in such a way that the air passing through is exposed to a predetermined UV-C radiation dose.
