Curved lines and bright, matte surfaces define the appearance of ZERO-X, lending it a modern, friendly look. A special eye-catcher is the 15.5-degree tilted user interface. Its positioning facing the user skilfully picks up on the design ­concept and is also highly user-friendly, since the display is easy to read from a distance. The operation of the air purifier is intuitive. All functions can be ­controlled by means of three buttons.
