I have a small box of N95 masks in my shop - bought last summer for dust protection. When is the right time for me to put them on my family. Part of this is how long will they last before I must replace them. Or should I put them on eBay for a million dollars and hope I life to enjoy my new found wealth?
Surely you have elderly friends and relatives, give each one one of your masks (once things are dire enough that people will actually learn to use masks properly and not waste it.)
There isn't a shortage if you're a hospital. There's a run on the retail supply, and retail restocking will be very limited, if at all. But your local hospital is fine.
And it would have to be apocalyptic for them to accept a box of medical equipment from some guy wandering in.
