CARE FOR THE DEVICE

If the water is hard, which means it contains too much calcium and magnesium, it can cause a “white powder” problem and leave limescale on the surface of the water basin, transducer and inner surface of the water tank. Scale on the transducer surface will interfere with the unit operation.

We recommend:

Use cold-boiled water or distilled water.
Clean the transducer, water tank and basin every week.
Change the water in the tank often to keep it fre sh.
Make sure there is no water in the water tan k and humidifier base before storing the unit.
Clean the whole unit and make sure that all parts of the unit are completely dry before storing the unit.

Put 5-10 drops of cleaning agent/ vinegar on the surface of the transducer, wait for 2-5 minutes.
Brush off the scale from the surface.
Rinse the t transducer with clean water.

Clean the water basin with a soft cloth and cleaning agent/ vinegar if there is scale in it.
If there are deposits on the security switch, apply the cleaning agent/ vinegar on the scale and clean it out with a brush.

STORAGE

Unplug the device.
Pour all the water out of the reservoir. Dry the reservoir with a cloth.

WATER FILTER

The water is filtered through active carbon & mineral pellets.
Then the water passes through a container of ceramic pellets made from moissanite & tourmaline minerals that resonate with water particles on the far infrared frequency.
The ceramic pellets also generate negative ions to extract impurities.

How to install the water filter:

Install the water filter with the round holes down in the rectangular slot at the bottom of the water reservoir.
