There are vented N95 masks and NON vented N95 masks. In a global pandemic, do not wear any vented mask. The vent is a one way vent which protects the wearer of the mask. The vented mask allows all exhaled air including virus is that person is infected with Covid into the environment. We were told back in March 2020 not to wear any vented mask for this reason.
