Apparently NZ is doing a good job slowing covid. I heard that good news today.
Regarding n95, the instructions online say no longer than 8 hours, and of course not to reuse. I think it is due to a temporary electrostatic charge. You know the masks are stored sealed, but in the US, at least in CA, many of the supplies had been allowed to expire. So that charge must decay over time regardless.
