WHAT :

NanoHack, an open-source mask against COVID-19

The mask imagined by Copper3D should be antiviral, reusable, modular, washable, recyclable, and affordable. A traditional mask must be thrown away after some time (about 8 hours according to the Chilean company). The manufacturer immediately put the corresponding STL file online so that as many people as possible could print it and offer it to those in need. It also registered a patent.

According to Copper3D, NanoHack incorporates a scalable filtration system that uses a copper nanocomposite that has been proven to broadly inactivate viruses. This system would include several layers of different geometries to ensure effective filtration of fine particles. The mask is to be printed in several parts and then assembled; the company gives clear instructions on its site.
