“masks that have built in valves or vents aren’t actually effective”
The word, “vent”, is a clue. (Duh.)
My n99 has vents.
N99 filters better than N95
N95 filters better than the grandma sown together virtue signaling pseudo-fashion statement rags that are handled over and over again then put back on as muzzle

This is about control
Government controlling us
Freepers who are ill informed trying to control other freepers.
Sick of everyone’s crap
Live free or die
If masks are so effective YOU wear one
I’ll determine my own personal risks
I cut a slit in my surgical mask so I can breathe.
