Well, yeah, the medical masks are. You can get N95 respirators, which weren't what people were generally wearing, and those are aimed at that. Might actually be possible to buy some this time around; the shortage was pretty extreme in 2020.

I managed to get a reusable N95 3M respirator and filters early-on in the thing, before it was really in the news and everyone was rolling out the door of hardware stores with N95 respirators to ship to China and the like.
