From the esteemed idleprocess:
"Better filter media is better filter media, which mostly matters for occupational exposure. But if using something perceived to be better than 2 layers of cloth (not used at the expense of medical workers, emergency responders, others facing occupational exposure) is what it takes for someone to wear a mask, why not?"
The vape video clearly shows how most exhalation goes around, not through the mask. Adding more layers, whatever the quality or permeability, will further impede exhalation by the wearer through these homespun public-use masks. So yes, (boastfully) crowing about that kind of mask-belief may help others buy into that con.
And now that the main viral shutdown thread here on cpf has resumed I will endeavor to not continue this line of opinion here, on the fixer's thread.
