This whitepaper presents a cost-benefit analysis of implementing far-UVC lamps in various indoor settings to reduce airborne infections. It begins by outlining the significance of indoor environments in the transmission of airborne pathogens and the potential of far-UVC technology to enhance air quality. The study employs the CERN Airborne Model for Indoor Risk Assessment (CAiMIRA) to evaluate the effectiveness of far-UVC lamps in settings such as restaurants, offices, and hospitals. The analysis includes a comparison of costs and benefits, revealing that the benefits of deploying far-UVC lamps significantly outweigh the costs across different scenarios, including normal winters and pandemic situations. The paper also discusses policy recommendations for both the private sector and public institutions, emphasizing the need for real-world studies and monitoring of indoor air quality. Overall, the findings suggest that far-UVC technology is a viable solution for improving indoor air quality and mitigating the economic impact of infectious diseases.
