Abstract
Personal protective equipment (PPEs) such as masks are critical to filter microbes and pollutants from the air we breathe. With the on-going pandemic, there has been increased interest in evaluating different PPE material with a range of test aerosol. Methodologies to characterize particle penetration through filter media have largely been standardized, but the recent pandemic has shown the need to understand if test methodologies are sensitive to small changes in the setup such as test aerosol material, area of test filter, etc. Here, we use a well characterized filter test setup and evaluate a range of filter material using different aerosol types, charge states, and filter holder sizes to determine the robustness of penetration results as a function of face velocity. We will present our experimental setup and results of our study at the conference.
