Large particle penetration through N95 respirator filters and facepiece leaks with cyclic flow
The aim of this study was to investigate respirator filter and faceseal penetration of particles representing bacterial and fungal spore size ranges (0.7 – 4 µm). First, field experiments were conducted to determine workplace protection factors (WPFs) for a typical N95 filtering facepiece respirator...
