Face fit factor of 150 Fig. 1 Rig for testing filtration efficiency of respiratory protection equipments against viral aerosol Aerobiologia (2013) 29:365-372 367 means that the air inside the mask is 150 times as clean as the air outside the mask. If do not consider the face fit factor, both the surgical mask and N95 or N99 mask had good protection efficiency against viral aerosol in our study. The surgical masks and N95 or N99 mask used in this study were sealed to the face of the manikin, so their efficiency determined during viral aerosol protection experiments is defined as the efficiency of the filter material. Though the efficiency of the filter material of tested masks against viral aerosol was all [95 %, the protection factors determined by TSI8020 and N95 components were different greatly.	./cache/cord-257997-btj4ckkz.txt	./txt/cord-257997-btj4ckkz.txt
