To trap gaseous contaminants (odor/chemical substances) and particulate contaminants (dust, microbial particles, allergenic particles, and the like), and regenerate or recover trapping performance for predetermined contaminants, provided is a cleaning filter (4) to be used in an air cleaning apparatus (1), the cleaning filter including a gas trapping member (6) and a particle trapping member (5). At least one of the gas trapping member (6) and 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). Alternatively, the at least one of the gas trapping member (6) and the particle trapping member (5) includes: the trapping material (7) the trapping material holding member (8) and a trapping material supply device (10) for supplying the trapping material (7) to the trapping material holding member (8) so as to recover the trapping performance of the trapping material (7) for the predetermined contaminant.
