Air Filtration in Response to COVID-19, Dr. Thomas Caesar

Abstract: Air filtration has never been under such a high public focus as a safety requirement as it is today during the COVID-19 pandemic. There is a strong indication that the coronavirus can spread as aerosols via the air. As the virus may attach to smaller or larger particles (solid or liquid), a wide range of particle sizes must be considered from micrometers down to the nanoscale in terms of virus removal for personal protection.

Universal Method to Evaluate the Performance of Facemasks, Dr. Paolo Tronville, Politecnico di Torino, Italy

Abstract: Standardized test methods to assess the performance of surgical masks and personal protective equipment for the respiratory tract prescribe rather complicated and lengthy test methods using measuring equipment hard to find on the market. We present an innovative test method to measure the filtration performance of face masks based on ISO 16890 series. This method provides a clear and complete performance assessment, in a much shorter time, and providing data uncertainty. We present and compare the data obtained by testing the three categories of devices with the new method.
