Crystal IS - an Asahi Kasei company

Crystal IS manufactures high-performance LEDs that emit ultraviolet (UV) light to disinfect water, air, and surfaces in various applications. Founded in 1997 to develop and commercialize Aluminum Nitride substrates, Crystal IS is headquartered in upstate New York with R&D and manufacturing operations in Japan. Chemical disinfectants and treatments are often reserved for municipal and large water distribution networks, while point-of-use (POU) and point-of-entry (POE) systems rely on filtration and deep ultraviolet light (UVC). We work with industry leaders across water, air, and healthcare markets to provide mercury-free disinfection that enhances and sustains life and living worldwide.
