The second study used the same experimental setup, however studied a wider range of masks designs, together with a 4-ply cotton mask. For each masks design, over 97% contaminant filtration was noticed . Aerosolized transmission dynamics are pathogen specific, due to pathogen-specific peak shedding and inactivation charges .
