Pretty sure masks are more likely to protect other people from your germs rather than vice versa, I always wear a mask at my workplace and I still got covid (Delta 3 weeks ago, horrific, still suffering) from a work colleague despite the mask, no one vould believe it as I was one of only 2 or 3 out of a hundred employees who continued to wear one , 18 at my work got it, so 70 odd who didn't wear masks avoided it!
