I don’t think there are going to be any mask shortages for long time.
The studies are conclusive on the high effectiveness of N95. It’s the other masks that are stupid and not at all possessed of good study results.
This was a major screw up of CDC. If they had mandated N95, not just “mask”, there would have been no doubts about effectiveness. No one would have liked it, but there would have been no doubt about value to oldsters.
When DOJ wins mandate permission in its appeal, it should be restricted to N95. The stupidity of mandating worthless masks cause needless argument.
No one HAS to wear one. They can simply stay off airplanes.
