Easy maintenance since you can always carry it with you.

Particular considerations were made to formulate specifications for comfortable daily use.

  • 1. Water filling through a one-touch opening

    Simply twist the base unit to take out the water tank, which can then be filled with water directly from a tap.

  • 2. Replace the water sponge once a month

    The sponge should be replaced about once a month, and water in the tank must be replaced each day. This is the key to creating clean mist.


Change the light color to suit the mood or occasion.

There is more to the LED light than merely turning it on and off, as the color can be changed to your preference or turned on in graduated levels.
