ABSTRACT

As air and water quality continue to deteriorate, the market is increasingly saturated with products whose effectiveness has not been clearly verified. In response, this project aims to develop a future-oriented, compact, and modular product with enhanced performance and clearly demonstrated effectiveness. To realize this objective, the project will place emphasis on the development of UV-C LED device and process element technologies, together with high-efficiency and miniaturization technologies based on photocatalytic applications. Through this research, we present ‘Air purification and disinfection product’ study involving the development of a UV-C LED device with a 300 nm emission wavelength and the achievement of a 70 % acetaldehyde removal rate.
