Abstract
An air cleaner includes a negative ion generation portion generating negative ions, a positive ion generation portion generating positive ions, a drive portion adjusting a distance between the ion generation portions, a wind velocity sensor detecting wind velocity at positions where the ion generation portions are installed, and a microcomputer controlling the drive portion based on a detection result of the wind velocity sensor and setting distance D between the ion generation portions to an optimal value. Therefore, since the distance between the ion generation portions is set to the optimal value, a large amount of ion generation can be obtained.
