An air purification device for a vehicle comprises an air inlet, an air outlet, and an air conduction volume between the air inlet and the air outlet. At least one reaction surface element is provided in the air conduction volume. At least one light source for ultraviolet light is arranged in the air conduction volume. A surface of the at least one reaction surface element comprises a catalytic material, and the at least on reaction surface element is arranged substantially in the entire air conduction volume or occupies at least 50% of the inner surface of the air purification device. The air purification device comprises a base element and a cover element. The at least one reaction surface element is integrally connected to the base element or to the cover element and comprises surface-coated rod-shaped elements protruding into the air conduction volume.
