Like I said You dont have a clue what your talking about. Everytime you write something its obvious.
The masks I wear have exhaust valves, so I always inhale fresh air, not recycled air. Your probably one of those who walk around with your nose exposed, and don’t wear one properly anyway.
Balaclavas cover the chin or mouth, not your entire face over your nose. If they do, than they have a breath deflector like my Klim balaclava.
I have stuck a 4 head gas monitor hose under my cloth mask and it alarmed on low oxygen, that low oxygen reading would warrant a full breathing air apparatus in a confined space.
So before you go calling people names on their beliefs and opinions, educate yourself.
How you responded to another member on this forum was a total “Karen” move and it was not called for.
