- dragontamer 7y agohttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC3373043/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3373043/ Perhaps my advice is specific to repurposed T-shirt masks then. But this study boiled the masks before testing and use. The study was designed for poorer countries without as much infrastructure. Which is why the materials are so simple and the methods crude. But those attributes are very useful for the DIY community.
