Select N95 respirators & surgical masks based on the US Strategic National Stockpile and the VA study
Perform tests on each model and type (cup (n=18), horizontal flat-fold (n=6), and other flat-fold (n=6)), medium size (or M/L or universal), with and without exhalation valves, with and without surgical masks = 291 tests.
Analyses included a subset of paired-valve FFR (18 FFR) that represented identical FFR models, with and without exhalation valves
