Problems solved by technology
In particular, there are difficulties in removing aromas from the inhaled air, since different aroma substances also require different filter materials
However, if a corresponding amount of different filter materials is required for the increased number of different aroma substances, the flow resistance of the air filter increases, which hinders the economical operation of the air conditioning system

Embodiment Construction
[0035] according to figure 1 A not shown air conditioning system 1 for providing air conditioning of a vehicle interior 2 of a vehicle comprises an interior air filter device 3 equipped with at least one interior air filter element 4 . In the following, the interior air filter device 3 can also be referred to as filter device 3 for short. In the following, the inner air filter element 4 can also be referred to as filter element 4 for short. The air conditioning system 1 further comprises a fan 5 for generating an air flow 6 which is supplied to the interior 2 . Here the air flow 6 passes through the filter device 3 , that is to say through the filter element 4 , as a result of which the air flow 6 is cleaned. At the same time, the fan 5 is able to draw in recirculation air 7 from the interior 2 . Furthermore, the fan 5 is able to draw in fresh air 9 from the environment 8 of the vehicle. By means of the flap valve device 10 it is possible to switch between a recirculation ...

Abstract
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).
Description
technical field [0001] The invention relates to a multilayer filter material for an interior air filter of a vehicle. The invention also relates to an interior air filter for an air-conditioning system of a vehicle produced by means of such a multilayer filter material. Finally, the invention relates to an air-conditioning system for a vehicle equipped with at least one interior air filter of this type. Background technique [0002] In vehicles, especially road vehicles, there is a need to supply clean air to the vehicle interior, preferably the passenger compartment. The air supply for the interior of the vehicle usually takes place by means of an air-conditioning system which takes in air from the interior, cleans the air by means of an interior air filter and returns it to the interior (circulation air mode), or takes in fresh air from the environment, The air is cleaned by means of the internal air filter and supplied to the interior (fresh air mode). Likewise, any nu...
