Effectiveness of Medical and Cloth Masks for COVID-19 Protection Webinar Archive
This webinar, recorded on January 27, 2021, featured Dr. James Samet, Senior Principal Investigator, and Dr. Steven Prince, Principal Investigator, in the Center for Public Health and Environmental Assessment of EPA's Office of Research and Development, presenting on “Effectiveness of Medical and Cloth Masks for COVID-19 Protection.” Despite widespread adoption of face mask use for personal protection and to help stop the spread of COVID-19, there is little or no public information available on the performance and efficacy of different types of masks or modifications on existing face coverings. Important questions, such as which type of mask to buy or make, what modifications can be made to disposable medical-grade surgical masks and other face coverings, or the compatibility of facial hair with protective face coverings, remain.
EPA researchers are collaborating with University of North Carolina partners to test the fitted filtering efficiency of face coverings available to hospital workers and the general public, as well as the relative performance of face coverings for individuals with beards. This webinar highlights three of these collaborative projects and their impact in informing healthcare workers and the public on their best options.
