Mask Valve (Tesla type)

The project describes the manufacture of a Tesla-type valve that can be applied to DIY masks or valveless masks.
Using valve-equipped masks has a number of practical advantages. The valve facilitates breathing and prevents moisture from forming
inside the screen, without compromising its clinical requirements.

The main advantage of a Tesla valve over a traditional valve lies in the lack of moving parts. This has a double advantage, in fact
It allows you to print the entire valve in one piece and at the same time increases its lifespan in terms of wear. The valve is reusable after washing in a disinfectant solution
(ethyl alcohol, diluted sodium hypochlorite or a commercial disinfectant).

Operationally, the valve can be applied by making a cross-cut in the fabric of the mask and fixing everything with the supplied bolt.
The valve is designed to promote outflow and slow down the incoming flow. In addition, the design is such that any powders and any micro-dropes can be blocked
