Incidence of fit test failure during N95 respirator reuse and extended use




About The Study: In this study of 824 N95s used by 412 emergency department health care workers practicing N95 reuse, fit failure occurred in 38.7% of masks after one shift. Trifold N95s had higher incidence of fit failure compared with dome N95s. These results may inform pandemic preparedness, specifically policies related to N95 selection and reuse practices.

Authors: Ralph C. Wang, M.D., M.A.S., of the University of California, San Francisco, is the corresponding author.
