PROBLEM TO BE SOLVED: To provide a semi-liquid filter box for dust which is capable of sucking and removing the dust of particulates by a unique structure utilizing an air current and stream current simply by connecting and activating vacuum apparatus and is handy and light in weight. SOLUTION: This semi-liquid filter box for dust has firstly an effect of the air current by serrated suction induction pipes, secondly a removal effect by circulating water and abutting the stream current and the air current and thirdly the ability to remove the dust by an air filter and to remove the particulate dust simply by connecting and interlocking the filter box to the vacuum apparatus, etc. Since the dust stagnates in the water, the soaring up of the dust does not occur any more and the problems in terms of maintenance, workability, cost effectiveness and fluidity are solved.
