You will need this to adapt the mask to the turbine : https://www.thingiverse.com/thing:4295491

Put the sound on, imagine you have a dust mask on your head and you breathe normally into the mask equiped with a powerful FFP3 cartridge...

Finally I must say that this system provides a really effortless way to wear a mask.
There is no effort to breathe, no moisture accumulated into te mask. And the positive pressure applied into the mask gives to the user a perfect clean fresh and filtered tidal volume of air !

You can also use it as a spirometer. Unplug the venturi from the turbine then connect the adapter and blow !
