“I’m fortunate to not be feeling worse, but none of this shit has made me feel better…”
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!!!
