A dust collecting filter of a vacuum cleaner, which is reusable, is disposed in a dust collecting chamber in which contaminants entrained in air drawn in through an air inlet are separated and collected, and comprises a first case member 10 with an inlet hole 11 connected with an air inlet port (211, Fig 5) of the dust collecting chamber (210, Fig 5), a second case member 20 with a plurality of air discharge holes formed on a side surface (21, Fig 3) for discharging air travelling from the air inlet hole 11, is connected with the first case member 10 to form a predermined space in between the first and second case members, and a contaminant separating means 30 disposed on the air discharge path of the predetermined space for separating and collecting contaminants from air passing through. The dust collecting filter connects to a vacuum generating apparatus (300, Fig 5) disposed in a chamber of a vacuum cleaner. Preferably, the contaminant separating means 30 is a grill 31 having a cylindrical body covered on the outer surface by cylindrical porous material 35 such as sponge. Contaminated air is filtered firstly by the grill which removes large contaminants and secondly by the cylindrical porous material which removes fine dust. Advantageously, the dust collecting filter is reusable by washing off the collected contaminants.
