The invention discloses an air particulate matter filtering device. The device comprises a conductive filter screen device and a negative ion generating device, wherein the negative ion generating device is positioned at the upstream of the conductive filter screen device; the conductive filter screen device comprises a filter screen which is a conductive filter screen, and further comprises an electrode metal plate which is arranged between the negative ion generating device and the conductive filter screen device and can be connected with a positive high-voltage power supply; and the voltageof the positive high-voltage power supply connected with the electrode metal plate is higher than that of the positive high-voltage power supply connected with the filter screen. Negative ions generated by a negative ion probe are subjected to traction force of the electrode metal plate and the direction of the traction force is opposite to the gas flowing direction, so that the contact time of the negative ions and micr
