    Snippet: Our H0 (null hypothesis) = Disinfection treatment of masks (heat or UV) will not change the fit factor of masks as measured using OSHA standard protocols with a human model on the quantitative fit tester. To demonstrate effectiveness (preservation of fit), the treatment would show little or no change between the control (no treatment) and experimental (75°C Hot Air (30 mins) for 10 cycles) and UVGI (254 nm, 8W, 30 min) for 10 cycles) conditions......
