Maintenance
Cleaning the Diffuser

Figure 5: Important precautions regarding oil types and cleaning methods for the diffuser.
Regular cleaning ensures optimal performance and extends the lifespan of your diffuser. It is recommended to clean the diffuser monthly, or more frequently if you notice reduced mist output or change essential oils.
- Cleaning Solution: Use only 90% or greater ethanol or isopropyl alcohol.
- Cleaning Process: Remove the essential oil bottle and nozzle assembly. Carefully clean the nozzle and any visible oil residue with a cotton swab dampened with alcohol. Allow all parts to air dry completely before reassembly.
- Important: Do NOT use water to clean the nozzle or internal components, as this can cause damage.
Oil Compatibility
- Use only pure essential or fragrance oils.
- Avoid: Agarwood, camphor tree oils, resin, or thick oils, as these can clog the nebulizer and impair function.
- If using thicker oils, dilute them with appropriate carrier oils to prevent clogging.
- Oils generally thicken and become difficult to mist when exposed to sunlight or cold temperatures. Store oils properly.
Troubleshooting
Common Issues and Solutions
| Issue | Solution |
|---|---|
| Mist output decreases significantly after a month of use. | The diffuser requires cleaning. Refer to the Maintenance section for detailed cleaning instructions. |
| No mist is coming out, but the mist/power indicator is blinking. | The diffuser is currently in its pause cycle according to the selected mist intensity setting. Mist will resume after the programmed pause duration. |
