| Clean the water filter (see page 16) or replace the water filter sponge with a new one. One replacement water filter sponge is included with this humidifier. For information on additional replacements, contact Customer Support (see page 27). | |
| Humidifier uses water too quickly. | The humidifier uses up water based on the environmental temperature and humidity. If your environment is cold and/or dry, the humidifier will run out of water faster. |
| Using the warm mist function will use up water faster. | |
| Humidifier produces an unusual smell. | If the humidifier is new, unplug and rinse all parts, then place in a cool, dry place for 12 hours. |
| If essential oils were placed on the aroma pad, rinse the pad under clean water and allow it to dry. | |

| Problem | Possible Solution |
| Humidifier makes a loud or unusual noise. | Make sure the water tank is properly in place (see Getting Started, page 8). |
| Set mist level to a lower setting. | |
| Empty the base chamber. Refill the water tank (not the base chamber) and place the water tank properly onto the base. | |
| When using the warm mist function, the heating element may make a gurgling noise if the water level is low. Add more water to the water tank. | |
| The humidifier may be malfunctioning. Stop using the humidifier and contact Customer Support (see page 27). | |
| Mist leaks from the base. | Make sure the water tank is properly in place (see Getting Started, page 8). |

| Display shows an incorrect humidity percentage. | The room may be larger than the humidifier’s effective range. Move to a room smaller than 430–753 ft² / 40–70 m². |
| Moisture may have built up inside the humidity sensor. Make sure the nozzles are facing away from the aroma box so that mist does not settle on the sensor inside the aroma box (see diagram in Getting To Know Your Smart Humidifier, page 5). Turn off the humidifier, remove the aroma box, and allow the sensor to air dry. | |
| If the humidifier is placed within 12 inches / 30 cm of a wall or in a corner, the humidity sensor cannot provide a proper reading for the relative humidity in the room. | |
| The humidity sensor will give an improper reading if it is exposed to dust. Avoid using the humidifier in dusty rooms. Avoid using tap water in the humidifier, as this can increase dust in the air. | |
| The humidity level isn’t changing in my room. | Use a higher mist level setting. |
| Depending on your environment, the humidifier may take longer to humidify your air. | |
| The room may be larger than the humidifier’s effective range. If the room is larger than 430–753 ft² / 40–70 m², the humidifier will not be as effective. | |
