The air cleaning apparatus 100 sucks outside air, filters the air, and provides filtering air to the humidifier 200. The air cleaning apparatus 100 removes foreign matter contained in the introduced outside air and discharges the purified air from which odor and the like are removed to the humidifier 200. The humidification apparatus 200 humidifies the humidifier 200 by supplying the filtered air and provides moisture, and discharges humidified air to the outside.

The humidification device 200 and the air cleaning device 100 are separable from each other. The user can clean the humidifying apparatus 200 and the air cleaning apparatus 100 after separating them from each other. The user can remove the humidifier 200 from the air cleaning apparatus 100 and supply water to the water tub 30 disposed therein. The user may supply water in a state where the humidifying apparatus 200 is stacked on the air cleaning apparatus 100.

The air cleaning apparatus 100 includes a suction flow path 101 through which external air is sucked, and a filtration flow path 102 through which the suction air is filtered.

When the humidification apparatus 200 is stacked with the air cleaning apparatus 100, a connection flow path 103 is formed to receive filtered air. A connection flow path formed on the side of the air cleaning apparatus 100 is defined as a clean connection flow path 104 and a connection flow path formed on the side of the humidifier 200 is defined as a humidification connection flow path 105.
