All face masks help – Wel.nl

The Netherlands was one of the last countries where face masks were introduced. Reason: Jaap van Dissel did not believe that they had any effect.

He sits next to it. Caps do help. NRC studied the scientific literature and the verdict is clear: do not expect miracles from mouth masks, but they do reduce the risk of contamination.

And it doesn’t matter which mouth caps you use.

Chinese researchers have compared the various types of masks and come to the conclusion that in practice it makes very little difference. Measured over the entire range of droplets that are exhaled, an N95 mouth cap filters out 99.4 percent, and a cloth mouth cap 98.5 percent.
