Indoor environments are particularly conducive to the transmission of airborne pathogens, contributing to the propagation of infectious diseases. Since most people spend the majority of their time indoors, technologies like air filtration, ventilation, and UV radiation are essential for managing indoor air quality and preventing transmission of airborne pathogens. Among these, germicidal ultraviolet-C (UVC) light is a promising approach for real-time infection mitigation. 

Far-UVC, a specific wavelength within the UVC spectrum, can enhance indoor air quality by complementing ventilation and air filtration. While ventilation exchanges indoor and outdoor air, and filtration removes particle matter, far-UVC disinfects contaminated air and surfaces by inactivating viruses and bacteria. The increasing likelihood of pandemics, the COVID-19-pandemic and seasonal epidemics of respiratory infections underscore the importance of such technologies to mitigate and prevent the risk of transmission in indoor settings like offices, transportation, bars, and restaurants. 

The COVID-19-pandemic highlighted the limitations of non-pharmaceutical interventions, such as masks and disinfectants, due to issues like human error and societal acceptance. Far-UVC technology can offer a more reliable and less intrusive solution for mitigating indoor pathogen transmission. As part of a comprehensive approach, far-UVC effectively complements other public health measures in prevention, detection, and response efforts to disease outbreaks. This study addresses the need to also understand the economic implications of far-UVC installations in indoor settings.
