The cleaning filter includes a gas trapping member (6) and a particle trapping member (5). The gas trapping member (6) or the particle trapping member (5) includes: a trapping material (7) for trapping a predetermined contaminant in the air； and a trapping material holding member (8) for holding the trapping material (7) so as to be opposed to the air flow passage (3) with an air permeability ensured. The trapping material holding member (8) is subjected to, when removed from a cleaning apparatus main body (2), a regeneration process for regenerating trapping performance of the trapping material (7) for the predetermined contaminant under a state in which the trapping material holding member (8) holds the trapping material (7).
