I think that study is testing the opposite what what this suit provides -- it's not testing protection of the wearer, but testing whether or not the mask protects others: The median-fit factor of the homemade masks was one-half that of the surgical masks. Both masks significantly reduced the number of microorganisms expelled by volunteers, although the surgical mask was 3 times more effective in blocking transmission than the homemade mask.
