You might want to get a box of N95s ahead of the panic/rush.  Look for US made, NIOSH certified to avoid fakes.

N95 "duckbills" far outperform other mask types. KN95 ...not so good.

Saw someone on the plane who had a rubber respirator mask, but with N95 filters, so you get a good seal, but don't have to wear a full cartridge mask.

I was at the regional teaching hospital today for about 3 hours.  This is in the heart of rural, ultra-conservative NC.  During the covid pandemic this place was not the best at masking --frankly, doctors and nurses were pretty lax about it.  It took a mandate to get masking enforced.

Today, there was no masking mandate but I'd estimate that 50% of the people in the halls and common areas were masking and the canaries-in-the-coal-mine lab staff was 100%.

I think peoples knee jerk reaction is often "No", especially if somebody is spreading disinformation against it.   Later, when things are calmer they realize they over reacted so when the same situation comes around again (ie wearing masks) they are a lot more receptive.  People do learn, but it's a slow process and a lot of people can die in between.

I recently listened to a podcast about the death of President Garfield. He almost certainly would have survived the assassination if he had simply been left alone, but he was treated by a doctor who believed the writings of Dr Lister were utter nonsense that no right-thinking American would fall for and spent days probing for the bullet with unsanitized hands. This was many years after Lister had proved that washing hands saves lives.

And Garfield might have been a great president. At the very least, we know he wasn't power-hungry, because he endorsed a different candidate and even made a speech on the floor of the convention for the other candidate and continued to support that candidate after Garfield had been put forward, only finally acquiescing when he got a majority of the votes and the convention. Then in his early days in office showed himself to be a highly effective president. If only....
