9) Double masking (like Joe Biden when he traveled last year) also works. Or if you have a mask with a vent, wear another mask over the vented one.
Folks— *DOUBLE MASKING* could be the safer way to go. Biden used a surgical + N95, while I used a KN95 + KF94 (South Korea 🇰🇷 made). Not only do each offer better filtration than cloth mask, but also in case one is a fake knockoff (lots fake KN95s) and saves mask longer. #COVID19
