Cette étude est la première évaluation à grande échelle de l’efficacité de filtration des particules de trois modèles de masques respiratoires filtrants N95 après une utilisation clinique et une décontamination au peroxyde d’hydrogène vaporisé.
Summary This study is the first large scale evaluation of particulate filtration efficiency (PFE) of three models of N95 filtering facepiece respirators (FFR) following clinical usage and vaporized hydrogen peroxide (VHP) decontamination. Three variables were assessed for effect on PFE following VHP decontamination: VHP sterilizer model, N95 respirator model, and prior N95 clinical usage. The VHP sterilizer model and N95 FFR model impacted PFE performance. Worn N95 FFRs had a 91% lower odds of exhibiting ≥ 95% PFE compared with the control. This work highlights the importance of validating any N95 FFR decontamination program in its entirety, including prior clinical usage.
