Summary:A filtering device for a ballast water sampler relates to the technical field of ballast water filtering and comprises a base and a water storage barrel hermetically mounted on the base, and a barrel-shaped inner filter screen for filtering microorganisms with the grade of less than 50 microns is arranged in the middle in the water storage barrel. A cylindrical outer filter screen used for filtering microorganisms with the grade smaller than 10 microns is detachably connected between the cylindrical inner filter screen and the water storage cylinder, a first sampling area allowing microorganisms with the grade smaller than 10 microns to enter is formed between the cylindrical inner filter screen and the cylindrical outer filter screen, and a second sampling area allowing microorganisms with the grade smaller than 10 microns to enter is formed between the cylindrical outer filter screen and the water storage cylinder. The base is further provided with a compressed air inlet communicated with the interior of th
