From: Filtration efficiency of medical and community face masks using viral and bacterial bioaerosols
Filtration efficiency values (expressed in %, as defined in Eq. 2 at "Filtration efficiency calculation”) between bacterial filtration efficiency (BFE) and viral filtration efficiency (VFE) methods for the different types of masks evaluated in this study (MFM, CFM1 and CFM2; MFM refers to medical face mask, CFM refers to community face mask). ns not significantly different; experimental values (N = 5), mean with standard deviation.
