Puray / UVC Hand Sanitizer


Conventional disinfectant consists of alcohol and chemical-based liquids. They are flammable and hazardous to health when heaving contact to the eyes or getting swallowed. Because of this they are a great danger when not handled properly, especially for children and disabled people. However, for this group of people there is no alternative.
The Puray hand sanitizer illuminates the hands only with UV-C light, which eliminates all known pathogen on their surface without harming human cells. By providing a safe and intuitive hand hygiene for everybody, Puray contributes to the containment of diseases and the wellbeing for our communities
