Attention:

1. Ultrasonic humidifiers use pure water for humidification, because the water quality in many areas is hard, that is to say, the content of calcium and magnesium ions is high. In addition, some water purifiers such as bleaching powder are used in the water treatment of water factory. These ingredients are unfavorable for humidifier. Part of the calcium and magnesium ions are sprayed out along with the water mist, dispersed on the surface of the object and the ground, and form "white powder" after drying.

The other part precipitates on the surface of the transducer and the sink to form solid scale, which is caused by impure water quality, and after the surface of the transducer is scaled, it will affect the humidification effect, and if it is not cleaned in time, it will cause the transducer to increase its load and burn the transducer and electronic components.

2. Regularly replace the old water in the water tank, because the water storage time is too long, the water quality will change, so when it is not used for a long time, do not put water in the water tank and sink.

3. Do not add inferior additives (such as perfume and essential oils that are insoluble in water) to the water tank, which will easily cause cracks on the water tank and the base, which will affect the normal operation of the device. Please use pure plant essential oils, because essential oils containing chemical components are corrosive and will corrode plastics and key components

4. When storing the humidifier, please clean and dry the wetted parts. If it is placed in a ventilated place, it will be air-dried and packed into the packing box.
