On February 6, 2018 some of us involved in the Project Mistra TerraClean had a field day @ Camfil in Trosa. We had a wonderful day, where we had the chance to learn about the production of Molecular and particle filters. We also discussed multiple ways of approaching a smart material that can be used in this Project. Thank you @Camfil for giving us a tour around your factory & Tech Center. Very inspirational!
