Perhaps you are right about the loose fibers...but I make a point to not breathe through the mask. I breathe exclusively through the nose, which I leave fully exposed at the top of the mask.
I do as well, bet you still risk breathing the fibers from the top part of the mask that is near the nose.
“I breathe exclusively through the nose, which I leave fully exposed at the top of the mask.”
Cool.
I leave the mask around my chin as much as possible. Since the virus can be beaten with vitamins and perhaps some Ivermectin, the plandemic is over for me.
