Keywords: analysis, UV-C, mask, ergonomic, functional

Abstract: Usage of UV-C light is an economical and environmentally friendly technology for surface and air disinfection, but it’s used as stationary facilities in public buildings. This article presents an innovative product of a personal protection mask that uses this technology. It allows users to work in pathogen contaminated environment without affecting the aspiration. The developed design not only sterilizes the inhaled and exhalated air, but also provides ease of use, functional reliability and comfort fit across diverse facial topologies. The design is physically prototyped and experimental research was done on mixed male and female target group. The survey approved that the developed protective UV-C mask has good ergonomics, provides a secure facial seal and maintains an unobstructed field of view.
