- Switch Mist Modes: Once powered on, quick press the button (1 second) to cycle through the three intermittent mist modes.
Intermittent Mist Cycle Modes:
The diffuser operates with intermittent mist cycles only and does not support continuous misting. This design helps conserve essential oils.
| Mode | Mist Duration | Pause Duration | Cycle Duration | Operating Time | Standby Time |
|---|---|---|---|---|---|
| High | 60 seconds | 1 minute | 1 minute | 2 hours | 22 hours |
| Medium | 40 seconds | 3 minutes | 3 minutes | 8 hours | 16 hours |
| Low | 20 seconds | 5 minutes | 5 minutes | 8 hours | 16 hours |
Each cycle repeats until the operating time is complete, after which the diffuser enters standby mode. Turning the machine off and on, or changing the intensity, will reset the current cycle.
