Most people are surprised that N95/KN95/KF94 can be used more than 8 hrs. Actually the N95 spec requires that these masks maintain >95% after 200mg of loading. How much is 200mg, same as wearing the mask 24/7 in Shanghai for about 200 DAYS! Straps will be the first thing to fail
This is good news to me, because I totally reuse my N95 masks for weeks.

You need both a treasury secretery *and* a treasurer apparently.

This is pretty dumb, it's like the laws against using meat related words to describe meat replacements in Texas.
