To me, this somewhat old debate has always sounded a bit boring.
Face masks are for low-risk stuff. If a dentist is hovering above a healthy patient’s mouth, fixing their teeth, and doesn’t want large droplets to be communicated either way, it helps.
If however, someone has Ebola and a doctor goes to see them, well… in cases like that, doctors have always preferred to look like a cosmonaut - wear the highest grade of protective equipment they can.
Guidelines try to adress typical situations. If the context is an infectious disease of the respiratory tract, the ordinary masks, leaking from sides and near the nose, don’t offer a comfortable level of protection, even if their filtering capability is theoretically good enough. They just leak.

A mask is to protect the other person, a respirator is to protect the wearer.
Masks protect them wearer as well as those around. Apparently you learned fuck all.
You obviously didn’t even read the article.
