Respirators with nozzles help the spread of the virus.
The first respirators I could get my hands on were the N95 8210. It was easy to breathe in, but scientific study has shown the nozzles allow for droplets to leave the mask, although they can't enter. This means unknowingly to the user, they may be spreading the virus rather than containing it.
