A dust collector is provided to exchange and mount filters conveniently by installing dust collecting filters horizontally within a housing and installing an air ejection part vertically outside the housing. A dust collector comprises: a housing(10) which is formed in a hollow box shape, and which has a suction part(11) formed on a top part thereof, a hopper(12) formed on a bottom part thereof, and an exhaust part(14) formed on a lower part of one side thereof; dust collecting filters(20) which purify dust-containing air flown in through the suction part, and which have flanges(21) formed on one sides thereof; fixing units(30) for fixing positions of the dust collecting filters installed in mounting chambers of the dust collecting filters; and an air ejection pipe(40) for removing dust covered on the dust collecting filters, wherein installation holes are laterally formed in the housing, placement plates(16) are formed at both sides under the installation holes to support the dust collecting plates in the horizontal direction, air holes(19) are perforated into the rear side of the housing such that the air holes correspond with the center of each of the dust collecting filters, and the air ejection pipe is vertically installed outside the housing such that air ejected through nozzles(41) is supplied into the dust collecting filters through the air holes.
