A preprint of our report, Blueprint for Far-UVC. The report contains a comprehensive overview of the current state of knowledge for far-UVC, as well as a series of recommendations for advancing the technology’s development.

The Far-UVC Blueprint is a culmination of nearly two years of work, consisting of an extensive review of published literature and hundreds of interviews with experts across multiple disciplines.

It examines far-UVC’s efficacy at inactivating pathogens within safe human exposure limits, its photobiological safety for skin and eyes, and potential concerns like ozone generation. It outlines key recommendations for accelerating development, including research priorities to establish effective installation designs, identify biological effects, understand indoor air quality impacts, and obtain real-world effectiveness evidence. The report also details current emitter technologies, regulatory frameworks, UVC’s effects on materials, and considers ozone mitigation strategies. Overall, the report suggests that far-UVC technology could be a significant advancement in airborne infection control if certain research priorities and implementation guidelines are addressed.
