Abstract: A particles capturing system includes a venturi filter device, a cyclone filter device, a plurality of first nozzles and air to flow through the system. The venturi filter device has an air intake portion, a neck portion and an air outlet portion. The cyclone filter device, disposed in the air outlet portion, has an entrance and an exit. The plurality of first nozzles, disposed inside the venturi filter device, have a height greater than that of the the neck portion. When the air flows, the air enters the venturi filter device via an air inlet of the air intake portion, then orderly passes through the neck portion and the plurality of first nozzles, then enters the cyclone filter device via the entrance, and finally leaves the cyclone filter device via the exit, such that particles in the flowing air can be captured.
