The at least one active material is the same in all of the filter layers. The filter layers are to be flowed through serially in a through-flow direction of the filter body. Sensor devices are provided, wherein each sensor device is arranged between two of the filter layers neighboring each other, respectively, so that the sensor devices, in the through-flow direction of the filter body, are arranged one after another in order to determine a sorption capacity of the at least one active material of each filter layer over a service life of the filter body.",
