This 3D model has not been approved by any regulatory agency and has not passed any laboratory tests. It is a prototype designed by LAFACTORIA3D (a Spain-based company), presented among many other works in the CORONAVIRUSMAKERS community, created with the aim of providing emergency protective material to medical professionals who need it, given the current global shortage of supplies. It is not intended to replace any homologated mask, but to provide minimal protection. We cannot guarantee its operation, so use it at your own risk.
