EurekAlert: Proper fit of face masks is more important than material, study suggests

EurekAlert: Proper fit of face masks is more important than material, study suggests. “The researchers, from the University of Cambridge, carried out a series of different fit tests, and found that when a high-performance mask – such as an N95, KN95 or FFP2 mask – is not properly fitted, it performs no better than a cloth mask. Minor differences in facial features, such as the amount of fat under the skin, make significant differences in how well a mask fits.”
