About youvee
During lockdown in spring 2020, Frenell’s managing directors Martin Selig and Dr.Ing. Max Mertins started developing youvee to offer a technical solution against the global pandemic. The engineers, with over 15 years of industrial experience in the areas of ventilation technology and architecture developed youvee. The project was created off the back of increased demand by the public for an innovative air cleaning system that is both effective and stylish.
For decades, air purifiers were just doing it's job. However with the rising threats of airborne viruses, air purifiers have become an integral part of daily life. With that, not only demand for smart technologies but also for better design arose.
The profound expertise of Max and Martin were incorporated into the technology, design, and production process of youvee.
