Why bother. There's already testing done by those with the right equipment. Im just gonna go with you dont believe the tests done.
Well that would just be wrong.
I suggest the tests are not done under real world circumstances.
I have a lifetime of experience using every form of PPE for the breathing area.
N-95
I know first hand how the masks react when used for a long shift.
Put a rubber seal around that fucker and squeeze it tight to your face like there is a toxic substance in the air.
No beard allowed.
Let it get soaked from your breath.
I will bet you will not be able to walk down the street and breathe properly.
Keep it sealed tightly no cheating.
That is another thing.....
How does facial hair fit into the equation?
I know but you will not believe me, so I will leave it there.
