The definition of N95 literally means it filters 95 percent of particulate matter - as small as PM0.3 microns, much smaller than PM2.5."

N95 mask sale is increased a few time more in China. You can get N95 mask online in China.... Your friends had no enough knowdge about this, and so he could only asked you to help it in the US . Actually 3M already shipped a huge amount N95 mask to China.
