N95 as per FDA: 5 percent of very small (0.3 micron) test particles (the virus is .3 to .5 micron let's say)
THIS MEANS THE GOV ADMITS THE N95 DOESN'T WORK, btw
IS NOT AN N95 MASK as per above specification
a saw dust mask - saw dust is still breathed it goes right around the corners - but sawdust isn't poisonous so it doesn't really matter (it REDUCES the amount of sawdust inhaled - that's what a sawdust mask does and is designed for)
this also is FAKE, it is a sawdust mask by 3M THAT IS MADE IN CHINA (meaning, the gov is making deals to bail out a foreign company and commit medical fraud)
two reason this mask is fake: #1 it's for sawdust, used in that industry for several decades
#2 the "ventilator" is illegal - it allows and infected person to breath out the virus and spread it to others, which is counter-productive. so it both lets viruses IN AND OUT
