PROBLEM TO BE SOLVED: To provide an air purifying device capable of efficiently inactivating particulate matter of various types and sizes. An air purifying device according to the present invention is provided in an air air passage and is downstream from a first discharge unit 101 that discharges into the air passing through the air passage and a first discharge unit 101 of the air passage. A second discharge unit 102 that is provided on the side and discharges into the air passing through the air passage, and a second discharge unit 101 that applies a voltage having a first waveform to the first discharge unit 101 to discharge the discharge. A power supply unit 201 of 1 and a second power supply unit 202 that applies a voltage of a second waveform different from the first waveform to the second discharge unit 102 and discharges the second discharge unit 102. ..
