This thin and glossy unit will fit well in any interior of your home. The device will provide a dense mist consisted of water and plant extract vapors to freshen your house in no time. Since it humidifies air, it comes in handy during dry winter days.

  2. Since the device uses essential oils that are soluble in water, it fulfills the function of an SPA.
  3. The unit holds 1.5 L of water what is more than enough for the whole night.
  4. The device emits negatively charged ions, which are then absorbed by the skin surface for sustained physical and mental health.
  5. Once there is a lack of water in the reservoir, the device and LED light shut down.
  6. You can adjust the intensity and direction of the sprayed mist.

  • The unit is efficient. With a low setting, it can run about 20 hours without any refills.
