If masks don’t keep out some particles, then how do they filter dust & pollen?
Also, if normal masks don’t protect you from others who are sick then why do so many medical personnel wear them?
Last, if masks potentially do more harm than good, why has ever CDC interview been followed with a statement about how a mask shortage would adversely affect first responders and medical personnel’s ability to do their jobs?
Their logic is flawed so maybe masks are better than they say?
