A plasma air purifier device capable of producing large quantities of positive ions and negative ions for the purpose of air treatment and purification. Working under graphite point discharge the present invention produces a large number of small ion clusters which collide with oxygen molecules in the air in order to produce positive and negative ions. The power supply works in conjunction with the main circuit board sending current to the discharge needle array in order to produce positive ions via the first electrical lead. Current is also sent to the discharge plate in order to produce negative ions via the second electrical lead. The plasma air purifier has different modes of function allowing for different cycles of air purification.
