The air cleaner according to claim 5 or 6, wherein the switching damper is controlled in accordance with a particle size of dust so that a blowing direction from the blowout port can be changed to a depression angle, a horizontal direction, and an elevation angle direction. The air cleaner according to claim 4, wherein when the dust sensor detects dust having a large particle size, the control unit lowers the wind speed of the blower and sets the blowing direction of the blowing louver to the horizontal direction or the depression direction. The air cleaner according to any one of claims 5 to 8, wherein a blowout outlet is provided with a blowout louver whose angle can be adjusted in the elevation direction and an expansion louver that widens the angle in the left-right direction. When a negative ion generator is provided at the air outlet and the dust sensor detects dust with a small particle size, the control unit sets the outlet louver in the elevation direction and generates negative ions from the negative ion generator. The air cleaner according to any one of claims 5 to 7.
