I admit – I’m obsessed with masks. I have three-layer cotton ones from Old Navy; two-layer cotton ones with a filter sewn inside; blue disposable masks bought in bulk from Costco; a precious stash of KF94s sent via my mom from relatives in Korea; and stylish nylon masks that promise “breathability” but seem a little too flimsy for comfort.
I have no idea which of these masks works. Lately, I’ve been double masking, as the CDC recommends, but are my two masks really effective? Some consumer labeling would be nice, as I argue here in Washington Monthly.
