| Moisture may have built up inside of the humidity sensor. Turn off the humidifier and allow the sensor to air dry. Make sure the nozzles are facing away from the sensor. | |
| If the humidifier is placed within 12 in / 30 cm of a wall or in a corner, the built-in 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. | |
