Sounds good if one wears a new clean mask everyday....They give us a clean one daily at work. However, many are wearing the same mask over and over and they can easily become contaminated from any number of bacteria or viruses. Which means you then are sucking them into your nasal passages and lungs repeatedly....
Addition: Then some fail to realize one of the reasons the body was made to cough or sneeze........That reason being to clear the lungs and nasal passages of infection and contaminants. But the mask lets them stay right there so you can suck them in again....Win, win, lose, win, lose, lose?????
