Possible Causes

Humidity sensor blocked by mist outlet, Sensor contaminated with dust or moisture, Unit placed too close to walls or windows, Faulty humidity sensor module

How to Fix / Troubleshooting

Safety: Unplug the unit before accessing internal sensors.

  • Relocate unit: Place the humidifier in a more central location away from direct mist contact with the sensor, walls, or windows.
  • Clean sensor area: If the humidity sensor is accessible (small vented module near air intake), gently blow dust away with compressed air or a soft brush.
  • Compare with external hygrometer: Use a separate hygrometer to check actual room humidity and compare with the unit’s reading.
  • Replace sensor: If readings are consistently inaccurate by a large margin, replace the humidity sensor module with a Pure Enrichment–compatible part.
