When the humidifying filter 5 has its frame 52 set in the portion of the main body 1 which is a flow path on the discharge side of the blower 3, the water absorbing water suspended from one end of each humidifying element 50. The water supplied from the water tank 6 into the water receiving tray 15 is sucked up through the suction part 53 by the capillary action, and the humidifying element is disposed. The humidifying element 50 is supplied to the humidifying element 50. Since the suction part 53 projects below the humidifying element 50, water does not drop from the humidifying element 50.

Now, when the tank 6 filled with water is mounted on the main body 1 and the on-off valve 65 is opened, water is supplied to the humidifying element 50 of the humidifying filter 5 as described above. When the blower 3 is operated in this state, the air that has been cleaned by passing through the air cleaning filter is discharged from the outlet 16 through the humidification filter 5 into the room. At this time, the air passing through the humidifying filter 5 passes along the surface of the humidifying element 50 from the lower side to the upper side through the vertical gap formed by the corrugated spacers 51 between the humidifying elements 50, and humidifies. The moisture held by the element 50 evaporates and humidification is performed. Further, the moisture lost from the humidifying element 50 by the vaporization and evaporation
