Original Note:
Even more efficient N95 masks only filter particles, including viruses, not small molecules like aqueous vapour and gases, such as oxygen or carbon dioxide. They are called respirators for this reason, they retain particles but you can still breathe. https://www.fda.gov/medical-devices/personal-protective-equipment-infection-control/n95-respirators-surgical-masks-face-masks-and-barrier-face-coverings https://en.wikipedia.org/wiki/N95_respirator
