The hollow filter element is provided with at least one filter bellows made of at least one filter medium surrounding at least one element interior circumferentially relative to an element axis of the hollow filter element. At least one grip device is arranged at an end face of the at least one filter bellows that is not provided for passage of air in operation of the hollow filter element. The hollow filter element can be gripped by the at least one grip device at least for installation into or removal from the filter housing.
