N95 respirators: quantitative fit test pass rates and usability and comfort assessment by health care workers.

ABSTRACT:

Objectives

To compare the performance of four N95 respirator types with respect to quantitative fit test pass rate and health care worker-rated usability and comfort.

Design, setting, participants

Health care workers who participated in the respiratory protection program at the Royal Melbourne Hospital, 1 October 2020 - 31 May 2021. Participants underwent quantitative N95 respirator fit testing (at least three of four types: semi-rigid cup, flat-fold cup, duckbill, and three-panel flat-fold types), and were invited to complete an online usability and comfort assessment for respirators for which their fit test results were passes.

Main outcome measures

Fit test pass rate, and user-rated overall comfort and assessment ratings (five-point Likert scales), by N95 respirato
