The much and probably deservedly maligned full-face snorkel dive mask may be getting a new lease on life as it may help in supplying protective breathing gear for hard pressed medical workers by providing a reusable mask that completely shields the face.
Ocean Reef Launches Adaptor To Change Full-face Snorkel Mask Into COVID-19 Protective Mask | Scuba Diver Mag
Ocean Reef, which produces full-face diving and snorkelling masks, has created an adaptor which will fit to their snorkelling product and transform it into a COVID-19 protective mask.
Here are modified dive masks already in action produced by another group. As the situation worsens there has been a shortage of protective gear, much of it single use, but here only the cartridge needs replacing as the masks are able to be cleaned.
