Special Health and Hygiene Features:

  • Pure Steam Output is bacteria and mineral free, for the cleanest and healthiest form of moisture. The boiling process eliminates bacteria and viruses, and leaves any lime scale and calcium mineral deposits behind in the humidifier, ensuring only 100% pure and natural steam enters your air. No bacteria and no white dust!
  • ClearMist Technology eliminates the burn risk associated with other warm mist steam humidifiers, which means you can safely put your hand right to the steam output. How is this possible? Water is heated internally to the boiling point. A small and quiet fan then automatically lowers the temperature of the steam just before it exits the unit, keeping the steam temperature safe to the touch! ClearMist is warm to the touch instead of burning hot, making this the first steam humidifier safe for use around children.
