Abstract
A air cleaner includes a blowing device and a circulator movably disposed above the blowing device. The circulator includes a housing extending in a front-rear direction, a first inlet being formed in a rear portion of the housing and a first outlet being formed in a front portion of the housing, a circulation fan disposed in the housing to suction air through the first inlet and then discharge the air through the first outlet to a front of the housing, and a motor rotating the circulation fan. The first inlet is disposed above a second outlet of the blowing device inside an imaginary extension surface vertically extending an edge of the second outlet, and has a diameter smaller than a diameter of the second outlet, thus suctioning air discharged from the second outlet and increasing an intake ratio of clean air that undergoes a cleaning operation of the blowing device.
