The Earth Institute at Columbia University has recently published a paper in the Journal of the International Society for Respiratory Protection that looks into whether disposable masks can be disinfected by heating them without compromising their effectiveness. The authors, who include life and earth science teacher Lee Magadini, also compared the effectiveness of medical-grade masks with homemade ones, and looked into the feasibility of improving masks with homemade nose clips. Here’s a description of a paper she coauthored, which contains a link to the paper itself, published in the Journal of the International Society for Respiratory Protection. Congratulations, Ms. Magadini!
