Abstract

The supply of N95 respirators has been severely strained by the coronavirus disease 2019 (COVID-19) pandemic. We used quantitative fit-testing to evaluate 16 participants and 45 respirators through up to 4 rounds of ultraviolet decontamination and clinical reuse. The mean fit-test failure rate was 29.7%, and the probability of failure increased through N95 reuse.
