Figure 14 : Overall Pass/Fail for 3 manufacturers of N95 masks. Data show that heat does not significantly decrease fit factor, however UVGI treatments decrease fit factor on average 77.4% (p = .00024), which was statistically significant. Figure 15 : The 8200 mask removed from UVGI treatment prior to placement on human model. Straps were not manipulated or stretched. The lower strap was noted to be broken on both UV-treated masks.
