Abstract: An air cleaner includes a fan that is configured to suck air in an axial direction and discharge air between the axial direction and a radial direction. The air cleaner further includes a fan motor that is configured to rotate the fan. The air cleaner further includes an air guide unit that includes a cylindrical outer wall and an inner wall that is located in a center portion of the outer wall and that defines a space that is configured to receive the fan motor. The air guide unit defines an annular air flow path that is configured to receive air discharged by the fan and that is defined by an inner circumferential surface of the outer wall and an outer circumferential surface of the inner wall. The air guide unit further includes a plurality of guide ribs. The air guide unit further includes a plurality of flow guide protrusions.
