Testing Mask Reuse with Computer Simulations

To help hospitals make the most of what supplies they have on hand, Yale alums and CEID staff have developed computer simulations to predict the mechanical properties of face masks when they’re reused. Worldwide shortages may require hospitals to sterilize and reuse N95 masks designed for single uses. The computer simulations this team has developed take into account various failure modes of masks such as contamination, strap breakage, and filter efficiency to determine how many hours, on average, a given mask can survive in a hospital.
