An air purifier highly efficiently circulates an air flow to improve an indoor air environment without an increase in the air flow volme of the air purifier. The air purifier (1) is used placed on a floor surface (F), near a side wall surface (W1) of a room, and has an air inlet opening (122), an air filter (150), an air outlet opening (131), and a fan (170). When the air purifier (1) is used placed at a position within the range of 100 < L < 600, with L being the distance (mm) from the center of the air outlet opening (131) to the side wall surface (W1) of the room and H being the distance (mm) from the center of the air outlet opening (131) to the ceiling surface of the room, the angle Θ (°) between a line extending in the direction of an air flow from the air outlet opening (131) to a line extending vertically upward from the opening (131) is set within the range of tan(L/H) < Θ <= 35 in order that, among air flows, the air flow delivered from the air outlet opening (131) first reaches the side wall surface (W1) inside the room.
