Snippet: Data for the effect of mass loss on filtration efficiency for two of the 3M TM N95 respirators are shown on Fig. 2 . The large error in the mass measurements during the main drying interval was due to continued evaporation during the time the masks were on the testing rig with air being forced through them, as shown in Fig. 1 . In both cases, the filtration efficiency approached its initial value as the mask weight approached its initial values, .....
Document: Data for the effect of mass loss on filtration efficiency for two of the 3M TM N95 respirators are shown on Fig. 2 . The large error in the mass measurements during the main drying interval was due to continued evaporation during the time the masks were on the testing rig with air being forced through them, as shown in Fig. 1 . In both cases, the filtration efficiency approached its initial value as the mask weight approached its initial values, indicating that liquid adsorbed in the washing process reduced filtration efficiency.
