COVID 19: At this time, it has been requested that N95 respirators be primarily used by people who have direct contact with infectious people (like people who work in hospitals or nursing homes). You are right, being unable to make a seal can decrease effectiveness of a respirator. However, a surgical or cloth mask can still prevent the wearer from spewing droplets on others.
