How to make or buy a covid-19 face mask that actually works

How to properly remove your mask

Whatever mask-ish item you buy or make, one thing is crucial: Once you get back into your own home, treat the fabric as if it’s contaminated with viral cells. If you touch the outside of your mask—which has been exposed to any of the aerosolized droplets it’s protected you from—and then touch your face or objects around your home, you may put yourself at even greater risk of exposure than you would by simply walking around bare-faced. The point of wearing a mask is protecting other people from your germs, but that doesn’t mean it can’t end up being a vector for COVID-19 from strangers’ sneezes.

This guide explains how to remove different types of masks without touching the contaminated outer surface with your hands or face. Designate a receptacle for storing dirty masks and wash your hands with soap and water for 20 seconds once you’ve tossed a used one in.
