It is a valve model inspired by the "nanoHack" mask, allowing to create a FFP2 category filtering mask with a pad taken from a disposable ffp2 mask.

This makes it possible to make several effective masks with a single disposable mask (in case of lack, it can save lives...).

You will also find a DXF template for cutting the valve support (the mask) from a polypropylene sheet (laser or scalpel, depending on your tooling).

All you have to do is sew the mask beads into the mask to give it its shape, then glue the valve into the polypropylene mask and install rubber bands to hold it in place. (Don't forget to put a piece of FFP2 mask in the valve before you close it...)
