The Cube and Sphere air cleaning devices are designed for schools, hotels, offices and living spaces. The fan on the inside creates an airflow that runs through a coated membrane and past a UV lamp before being released to the outside. Small doses of hydrogen peroxide, which is created in the course of this process, clean the room air of bacteria and viruses. While the Cube model is defined by a rectangular basic structure and arching surfaces, the design of the Sphere model is based on an ellipsoidal shape.
