An air cleaner, comprising:
- an air cleaning module including a fan and a discharge guide disposed at an outlet side of the fan to discharge air passing through the fan upwardly;
- a circulator provided above the air cleaning module and comprising a fan housing in which a circulation fan is accommodated and a flow guide coupled to a lower side of the fan housing, the flow guide being configured to be disposed over the discharge guide and to introduce air discharged through the discharge guide toward the circulation fan;
- a rack for upward or downward movement of the circulator coupled to a lower side of the flow guide, the rack being moved upward or downward with the flow guide;
- a guide main body provided below the circulator to support the rack and positioned in a central area of the discharge guide;
- and
- a gear for upward or downward movement of the circulator provided at the guide main body, the gear being configured to be interlocked with the rack, wherein the circulator moves upward or downward between a laid-out state in which a rotational axis of the fan and a rotational axis of the circulation fan are positioned on a same axis and an erected state in which the rotational axis of the circulation fan is inclined with respect to the rotational axis of the fan.
