The water purifier features a circular touch control panel with LCD display that turns operating it into a sensual experience. In the left circular segment, users can control the water temperature in six steps from cold to boiling. The water flow is adjustable from 120 to 1,000 ml by a touch on the right side of the circle. The temperature and the flow rate are shown on the display and visualised by a colour scheme from pastel to black. In addition, a fine, raised line on each of the touch areas provides users with tactile orientation when tracing the circular shape with their finger.
