A cavity filter for low PIMD using hybrid cap bolts includes: a housing having therein a plurality of cavities partitioned by separation walls and an open upper portion; an upper plate coupled onto the upper portion of the housing and provided therein with a plurality of tuning bolts; a plurality of air blowing work holes formed respectively on the upper plate and outer sidewalls of the housing and corresponding to the plurality of cavities; and a plurality of hybrid cap bolts formed of different kinds of materials of metal and non-metal so as to have repulsive forces against and to be coupled to respective plurality of air blowing work holes. Thus, metal debris present inside a cavity housing are removed through an air blowing method by using an air blowing work hole formed in a cavity housing and a hybrid cap bolt for reducing PIMD.
