An ion diffusing apparatus is disclosed which can maintain a stable ion supplying capability. In the ion diffusing apparatus, the ion generator is detachable for easy maintenance and can deliver the positive ions and negative ions to a remote position while uniformly generating positive ions and negative ions. The ion diffusing apparatus includes an ion generator housing which houses the generator so that a positive ion generating part and a negative ion generating part are provided separately in a direction crossing a flow direction of a stream from a fan, and an ion generating surface is exposed which conforms to a stream flow surface of a stream flow passage extended from the fan to a supply opening. The ion generator may also be a cartridge which has an ion generating surface shaped to conform to the stream flow surface of the stream flow passage.

A disc-shaped filter unit including a filter main body having a water absorbability and a holder having a non water absorbability is disposed in a vertical orientation, with a part of a circumferential portion thereof immersed in water reserved in a water tank, and is rotated by a rotation drive mechanism in a circumferential direction. The filter unit has an absorptive region and a non-absorptive region arranged adjacent to each other in the circumferential direction. Therefore, in accordance with rotation of the filter unit in the circumferential direction, a state where the absorptive region is immersed and the filter main body of the filter unit absorbs water through a water-conduction hole and a state where the non-absorptive region is immersed and water absorption of the filter main body is prevented by a watertight section having a non water absorbability are continuously alternated.
