Indigo-Clean technology uses a visible wavelength of light—405nm—generated from state-of-the-art advances in LED technology, to kill harmful viruses and bacteria: oxidizing them from within. This visible wavelength of light reflects off walls and surfaces, providing disinfection even in shadowed areas. Indigo-Clean technology breaks the chain of infection between organism and host, which ultimately reduces the infectivity of bacteria and viruses, including those that cause Healthcare Associated Infections (HAIs), COVID-19 and the common flu.
