An N95 mask will do just fine. Do like millions of Chinese do.
I bought a box just the other day, and I may use them when I fly. And I’m going to act like a nut and carry some handwipes, too. I always thought it was, uh, unmanly, but now it seems sane.
I will be embarrassed, but I think some minimal precautions are in order. When’s the last time you heard of a plane being disinfected, including the ventilation system? Aside from a cabin air filter change, they do nothing. By the way, many planes are 15 to 20 years old.
Do they let you wear an N95 through security?
