Surely everyone already knows that an ordinary medical mask is a very unreliable means of protection against virus infection. Air chooses the path of least resistance, and most often this path runs through the cracks between the face and the mask.

However, some weaknesses were identified in the first model. In particular, the mask body did not retain its shape, which is why it had to be pressed harder to the face. Valve throughput was low for quick walking or running.
