@mikehatzenbeler @GarrLK @komonews The fit of a mask is critical to its performance. N-95s are only 12% effective with even a 1% gap. https://t.co/aktIgV0CHr For a fabric or surgical mask, the degradation of performance goes to zero with just a 3.2% gap.

@lymanstoneky Eh, 1-out-of-4 Even homespun masks by-and-large don't fail for lack of filtration efficiency, but by blow-by instead. (And certainly not "because the virrii are too small"; bare virons would be smaller than the MPP) https://t.co/wQrNYoML4Z
