Editing 2367: Masks

*'''{{w|Guy Fawkes mask}}''': A plastic mask that is a stylized depiction of {{w|Guy Fawkes}} (designed by David Lloyd for the comic book ''{{w|V for Vendetta}}'' and made popular by {{w|V for Vendetta (film)|its movie adaptation}} and subsequent adoption by the {{w|Anonymous (group)|Anonymous}} movement). Most Guy Fawkes masks provide small holes in the front for comfort, thus facilitating spread of the virus.

*'''{{w|Cloth face mask|Cloth}}''': A cloth mask that blocks most large particles, like virus-laden saliva.  To be most effective, it must cover nose as well as the mouth.  These are much cheaper than N95 masks, and can be reused by washing. Not all cloth masks are created equal, some designs and materials are more effective than others at holding back contagious particles, but Randall lists them under "Effective" on the whole.  They are relatively effective at preventing the wearer from infecting others, but are less effective at protecting the wearer from being infected by others, because droplets leaving the body are large enough to block, but small enough to get through cloth after evaporation. The felt-like nonwoven fabric of surgical masks blocks more droplets and aerosols than the same thickness of knit or woven fabric.

*'''{{w|N95 mask|N95}}''': A standard air filtration mask, commonly used in industry but also used in healthcare. The name "N95" signals that it is not resistant to oil, but successfully filters 95% of airborne particles. It has proven to be one of the more successful masks during the 2020 pandemic. N95 masks usually include non-woven filtration material, which while often stiff like cardstock, is more similar to the felt-like fabric of surgical masks than to woven cloth. N95 masks can [https://youtu.be/eAdanPfQdCA filter particles much smaller] than the gaps between layers and strands in the fabric.

*'''{{w|scuba set|SCUBA}}''': A '''S'''elf-'''C'''ontained '''U'''nderwater '''B'''reathing '''A'''pparatus. Most SCUBA equipment used an open-circuit design allowing exhaled air to vent to the atmosphere. Underwater, this would not be a threat to other divers who would also be breathing air from their tanks. However, on land a typical SCUBA regulator would expose others to virus particles. Closed-circuit SCUBA equipment recirculates the user’s gas supply but they still contain a means of venting extra gas into the atmosphere. Neither system contains expiratory HEPA filters making both ineffective at preventing virus transmission. That all said, SCUBA equipment still covers the face and nose, rather than directly exposing others to unshielded breathing and coughing.
