UV-C systems use ultraviolet light to inactivate airborne pathogens, including viruses and bacteria. The benefits of UV-C systems include their ability to provide rapid and effective air disinfection, with minimal maintenance and energy consumption. However, UV-C systems may not be effective against all types of airborne pathogens, and their effectiveness can be reduced by factors such as airflow rate, humidity, and particle size. Additionally, UV-C systems may not remove airborne particles, only inactivate them.
