  But at the time the risk was still small, because the virus was mostly not in the US yet. Article doesn't say the risk will remain small in the future, does it?

  Oh man remember this? If they’re used correctly, P95 and P100 face masks can reduce the likelihood of being exposed to coronavirus by blocking contaminated air particles. Currently, the Centers for Disease Control and Prevention (CDC) advises against people in the US using face masks because most people who aren’t trained medical professionals may not know how to fit them properly, and the risk of exposure in the US is so low to begin with.
