AIR FILTER COMPRISING A MULTILAYER FILTER MATERIAL

摘要

The invention relates to a multilayer filter material (12) for an interior air filter element of an air conditioning system in a vehicle. In order to obtain a particularly high adsorptive performance for odorous substances, the filter material comprises an active layer (14) containing non-impregnated activated carbon particles (16), an impregnated layer (15) containing impregnated activated carbon particles (17, 18), and an ion exchange layer (13) containing ion exchanger particles (20).
