Abstract
An air purifier has discharge electrodes which generate a corona emission. These discharge electrodes are disposed within a flow passage provided in the air purifier along with a blower. Also included in the air purifier is a filter which scavenges contaminant particles in the air charged by the discharge electrodes. A control unit detects a discharge current of the discharge electrodes to control a rotational speed of the blower in accordance with the detected emission current.
