Filtration Efficiency of Hospital Face Mask Alternatives Available for Use During the COVID-19 Pandemic | Infectious Diseases | JAMA Internal Medicine | JAMA Network

Question: How effective are the aerosol filtration efficiencies for fitted face mask alternatives used during the coronavirus disease 2019 pandemic? Findings: In this quality-improvement study of 29 fitted face mask alternatives, expired N95 respirators with intact elastic bands and masks that had been subjected to ethylene oxide and hydrogen peroxide sterilization had unchanged fitted filtration efficiencies (FFEs) of more than 95%, while the performance of N95 respirators in the wrong size resulted in decreased FFEsContinue…
