Mask covering nose and mouth is the terminology I believe you will find.
Aside from that, it may very well be open game.
I still encourage the avoidance of mask wearing, aside from suitable applications (sanding, welding, hockey goalie…)
Peculiar?
How many Union run shops were allowed to stay open during the shutdowns, while many smaller businesses had to close?
Need union dues to keep flowing?
Defund the opposition and tell them it is for their safety?
Question their patriotism if they disagree?
Mask Loophole noted.
I did NOT in fact see anything regarding covering air-intake valves/nostrils.
