The point of N95 masks is to prevent infecting health care workers that have work in close proximity to people that have the virus. The one way valve is to make the mask more comfortable to wear by reducing moisture built up inside the mask. Health care workers should be trained on how to properly wear a N95 mask.

A N95 mask does nothing to prevent the person wearing it from spreading the virus.
