I think that's why your supposed to wear it up over the nose and not under the chin. Obviously he's wearing it wrong...
kidding...
I will say though, coincidentally I just had to vacuum up sheetrock dust this past weekend from almost 40 sheets we just had installed and the symptoms from that were much worse than the symptoms from the rona oddly enough.
this mask is not the correct mask for dust.....also mask makers do not recommend sporting facial hair for a mask to seal properly....
when I did any Sheetrock work I used to wet the inside of the mask to help keep the inside of my nose moist to help stop the the dust from entering my lungs....it also helped to keep me refreshed...I found plaster/Sheetrock dust the most annoying...
when I was a welder I had a hood the had filtered pressurized air blowing in.
