Impact/Purpose:
This presentation summarizing EPA's research on air treatment technologies will be given at the National Academies of Sciences, Engineering, and Medicine’s Transportation Research Board’s Transit Cooperative Research Program Insight Event – Air Quality in Transit Buses.
Description:
The COVID-19 pandemic has highlighted the role that airborne transmission can play in the spread of disease. Accordingly, there is increased interest in technologies that claim to reduce or eliminate virus transmission via aerosols in occupied indoor spaces, such as in schools, transit systems, and office buildings. Current limitations on data availability and test design make it challenging to compare how effective different types of technologies will be at reducing the risk of exposure to airborne pathogens in real-world settings. EPA researchers have been evaluating the efficacy of different types of aerosol treatment technologies using a standardized, large-scale testing approach, which facilitates cross-technology comparisons and generates results that are translatable to real-world settings. This presentation will provide an overview of the research methodology and present results from evaluating different types of air treatment devices with a focus on the transit environment.
