Objectives Far-UVC (200-230 nm) is a range of wavelengths growing in popularity for use as a means of airborne virus disinfection in occupied public spaces. These wavelengths quickly and efficiently inactivate airborne pathogens, while remaining low risk to room occupants. As there is a drive to implement these technologies in public spaces, it is important to assess public opinion to ensure appropriate use and understanding of the technology. Methods A survey was distributed through social media channels with several questions to gather opinion on the use of Far-UVC. Results There were 111 respondents to the survey. Less than one third of respondents had heard of the term ‘Far-UVC’. Though, on learning about the core principles of Far-UVC, respondents became more supportive of its use in public spaces. Acceptance of Far-UVC was strongest in areas where a higher benefit-risk ratio was perceived, such as in hospitals. Conclusion Without a general understanding amongst members of the public, Far-UVC may face challenges in gaining widespread adoption. The assessment of public opinion presented here will help to determine where primary concerns lie, and the actions needed to address these.
