When I deign to wear one, that is all I wear. I must have a hundred of them in the garage.
If “you” took high-speed, smartphone videos of people wearing various mask designs sneezing, I wouldn’t be surprised to see nasal blast momentarily separating mask from some faces and escaping to environment.
Also, noting that masks also probably interfere with maximum skin vitamin D production, my non-medical advice is for artificial lighting urbanites to start taking vitamin D3.
