  • Do not refill the tank by pouring water through the top atomizing misting port of the humidifier. 
  • This humidifier is equipped with an Anti-Dry probe which will cause the humidifier to shut down automatically when the water level gets too low.
  • The Anti-Dry probe relies on electrical conductivity found in drinking water and since purified water has a very low electrical conductivity levels we do not recommend using purified water.
