PURPOSE: A dust collecting apparatus of a central concentrated type vacuum suction system is provided to extend the lives of filters by collecting the pre-determined amount of dust using a plurality of filters. CONSTITUTION: A dust collecting apparatus of a central concentrated type vacuum suction system includes a chamber(100), a filter(130), an air transferring path(200), and a blower(300). Air sucked through the inlet(122) of the filter housing(110) in the chamber and upwardly moves to be exhausted through the outlet(112) of a base(120). The filter includes a filter combining unit and a filter bag. The filter combining unit is composed of an insertion part and a flange. A hole is formed in the insertion part. The flange is formed at the lower part of the insertion part. The insertion part is covered with the filter bag. The filter is detachably installed in the filter housing. An air transferring hole is formed at the lower side of the filter housing. When the filter combining unit is inserted into the air transferring hole, the flange is supported by the peripheral part of the air transferring hole.
