The theory of this mask is: as a person wearing a mask breathes in and out, air flows through the mesh repeatedly, and any viral particles in the air are slowed down and discarded by mesh and high temperatures. Such a mask could be of benefit to health workers and members of the public in circumstances where social distancing would be impossible to achieve, such as a busy bus.
The design of this mask is completely new. Instead of mainly preventing the virus, it enables the virus to move through the mask, but slows it down and inactivates it.
