Black Face Mask
Breathability is an importance for consideration, too, because of the nature of running black face mask for exercise. Some masks come with pollutants( or have the option to buy a sludge) for increased protection. I find wearing a mask with a sludge, still, makes it much harder to breathe. Adalja also says no bone should be running in an N95 mask — those will oppressively stymie breathing.
