A base is connected to the motor and a cover is connected to the underside of the base. Multiple blades are connected between the base and the cover. A space is defined between the between the base and the cover. The fan has multiple outlets defined between the blades and communicating with the space. An inlet is defined through the underside of the fan and communicates with the space. Multiple filtering members are connected between the base and the cover and located on the periphery of the fan to cover up the outlet. Air is sucked from the inlet and circulates by the rotation of the blades, and passes through the filtering members and flows out from the outlets.
