Levoit humidifier displays HI humidity and stops misting even though the room does not feel very humid.

Safety: Unplug before internal work.

Steps:

• Relocate unit: Ensure the humidifier is not placed in a corner or enclosed space where mist accumulates around the sensor.
• Dry sensor: Turn off the unit and let it sit unplugged for several hours to allow condensation on the sensor to evaporate.
• Clean sensor housing: Gently clean around the sensor vents with a dry cotton swab to remove moisture and dust.
• Check wiring: Inspect the sensor harness for damage or loose connections.
• Replace sensor: If HI persists and independent measurements show normal humidity, replace the humidity sensor module.
