Routine maintenance

In some places, the tap water is “hard” (the content of calcium and magnesium ions is high) and some areas use water purifying agents such as bleaching powder. Therefore, when using humidifier, a part of calcium and magnesium ions are sprayed together with the water mist, spreading on the surface of the object and on the ground. After drying, it forms a water-alkali like white powder. Due to the impure water, a part of the precipitate forms scale on the transducer and the surface of base, which affects the humidification effect of the humidifier
