It's an air humidifier.
It uses molecular level selective volatilization technology to sublimate water directly through PTC materials, remove impurities in water, and then go through water purification washing treatment, and finally send pure water molecules to the air through the pneumatic device, so as to achieve the purpose of humidification. There is no requirement for water quality, no white powder phenomenon after humidification, and no scaling, especially suitable for North China where water quality is not good. In addition, there is a certain role in purifying the air, but the noise is larger.
