Mask Nerd Short - Fit, Fit, Fit!!!
Mask Nerd Short - Fit, Fit, Fit!!!

N95? KN95? KF94? The best is whichever fits you. I have high cheekbones & most N95s leak at my upper face. All Kf94s & most KN95s fit me perfectly, though, & I tie knots in ear loops to tighten just right. @masknerd has a great video: Fit, Fit, Fit!!!

I've been trying to explain this for two years now. N95s were designed primarily for male caucasian faces. KN95 and KF94 standards came about not because we wanted a knockoff mask standard, but because Asian faces could not pass fit tests with N95 masks.
