Primary Outcome
total fit factors(FFs) of the quantitative fit tests (QNFT) according to the wearing method of the three types of KF94 masks
Summary
Ear-loop-type Korean Filter 94 masks (KF94 masks, equivalent to the N95 and FFP2) are broadly
 used in health care settings in Korea for the COVID-19 pandemic. However, no studies have
 assessed the adequacy of respiratory protection. In this prospective randomized open-label
 study, the investigators aimed to evaluate the fitting performance of ear-loop-type KF94
 masks by the quantitative fit test according to the occupational safety and health
 administration (OSHA) protocol. In addition, by quantitatively comparing the tight-fitting
 method using a clip and the general-fitting method, the investigators tried to evaluate
 whether the tight-wearing method improves the fitting performance of KF94 masks.
