An air dryer cartridge, in particular for a compressed air treatment system of a commercial vehicle, includes a cartridge housing having a closed housing cover, an inner housing arranged in the cartridge housing, a desiccant accommodated in a space between the cartridge housing and the inner housing, a filter arrangement arranged inside the cartridge housing and positioned in the compressed air stream upstream of the desiccant in relation to normal operation of the air dryer cartridge, and a bypass for bypassing the filter device. A non-return valve, which blocks a compressed air stream in the direction towards the desiccant and allows a compressed air stream in the direction away from the desiccant, is arranged in the bypass. The non-return valve is formed in one piece together with the inner housing.
