UV-C is a proven disinfection technology which aim is to reduce the concentration of viruses, bacteria and other microorganisms present in the air that pose a risk to human health. The UV-C devices operate with a 254 nm dominant wavelength which inactivates the DNA of microorganisms, thus inhibits their growth. The purifiers are primarily recommended for offices, schools, healthcare facilities, waiting rooms, changing rooms in swimmingpools and sport complexes and other closed or poorly ventilated public areas. Since the technology is ozone-free, it can be used safely with human presence.
