Abstract: PURPOSE: To provide a humidifier, in which a treatment for bacteria elimination can be adjusted in adaptation to components of water, environment in which the humidifier is used, and user's request. CONSTITUTION: When the user presses an operation switch 20, and does not press a quiet switch 19 of a switching device 17, switch settings for a standard energization time and the time interval for an electrode 4 are made. That is, a CPU 11 reads contents of a RAM 12, which stores information on operation status of the switch 19 (S1), and sets T1 for non-energization time, and T2 for energization time (S3). The CPU 11 makes a judgement on whether the energization time has gone beyond an upper limit stored in the RAM 12 (S5), and as it has not gone beyond the upper limit, the CPU 11 makes entry of the data in an outside ROM 16 (S7). The CPU 11 sets T1 firstly for non- energization time (S8). The CPU 11 confirms the passage of time in a timer 14 (S9), and energizes the electrode 4 for T2 (S10). The CPU 11 confirms the passage of time in a timer 14 (S11), and returns to the initial state.
