Randomized crossover study comparing quantitative fit tests between Trident™ and 3M™ Aura™ N95/P2 respirators

N95 respirators for health care workers: the importance of fit, comfort, and usability

“…Ng and colleagues report considerable differences in the performance of the included respirators, including their fit test pass rates: 96.4% for the three‐panel, flat‐fold respirator, 65.0% for the semi‐rigid cup respirators, 32.4% for the flat‐fold respirator, and 59.2% for the duckbill respirators. Although the assessment of usability and comfort was subjective, marked differences in performance and user‐reported results indicated a strong preference for the three‐panel flat‐fold respirator, consistent with other reports 11 . However, performance differences between specific brands of this respirator type were reported by another Australian study, including significantly different fit test pass rates (overall: 3M Aura, 92.6%; Trident P2, 99.2%) 11 …”

Further, health care worker safety and wellbeing require ensuring that respirator comfort and usability is considered by policy and in practice.…”
