PURPOSE: A water level sensor of a humidifying air purifier is provided to improve the performance of the sensor by repeatedly undergoing exposure and precipitation according to the rotation of a rotary shaft. CONSTITUTION: A water level sensor of a humidifying air purifier includes a water storing bath(10), a disk assembly(30), a water level detecting part, and a connecting part(50). The water storing bath stores water. The disk assembly eliminates dust from air and humidifies the air using a disk(32) according to the rotation of a rotary shaft(34). The water level detecting part is connected from the edge of the disk to the outer lateral side of the rotary shaft. The water level detecting part detects the level of water in the water storing bath by implementing conduction. The water level detecting part includes a first sensor(42), a second sensor(44), a first rotating terminal(46), and a second rotating terminal(48). The connecting part is in electric connection with the water level detecting part according to the rotation of the rotary shaft.
