Frequently Asked Questions
Levoit red light keeps coming on with a full tank — cause?
A persistent red light with a full tank means the water level sensor or float is stuck or coated with mineral deposits. Clean the sensor area and float with white vinegar.
Levoit red light on but still producing some mist — is that okay?
If the unit still mists with a red light, the water level is very low. Running the transducer with insufficient water can cause damage. Refill immediately.
How do I know when to refill my Levoit humidifier?
Most Levoit humidifiers trigger a red light or stop misting automatically when the water is too low. You can also check the water window on the tank — refill when the level drops to the minimum fill line.
