Data underlying the research on influence of face velocity and exhaled breath condensate on the filtration efficiency of masks and mask materials for COVID-19 transmission prevention

In this research, the filtration capability of 15 types of masks and filter materials usable as insert in masks were tested at two different face velocities (10 and 25 cm/s). Four of these masks were tested at two additional face velocities (17.5 and 32.5 cm/s): level 3 surgical masks, two designs of cotton masks and disposable non-medical masks. Seven of these masks were also exposed to aerated simulated exhaled breath condensate (EBC) for 1 to 24 hours and their filtration efficiency was tested immediately following exposure.
