Rain Curtain
Rain Curtain is a combined air purifier and humidifier designed for home use. Water is circulated and sprayed onto the humidification filter from above, which keeps the filter moist and improves humidification efficiency. The filter is separated from the water tank to reduce bacterial growth. A semi-transparent window, named the rain curtain, makes the flowing droplets visible during operation. Four air purification functions and five water sterilization functions are included. Rain Curtain is controlled through the front touch screen or a mobile application.
