Our survey of an actual hospital PPE inventory shows that with the influx of non-certified masks, not all “real” masks function properly. These aren’t just alternative/homemade masks, but masks that purportedly function as an N95 mask.
Info on our accessible mask testing setup and PPE results are posted at https://covid.yale.edu/innovation/medtech/n95/ & https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3592485
Proud to have worked on this with Kate Schilling, Larry Wilen, all our other awesome co-authors, & the CEID to support frontline healthcare workers. We hope communities with limited testing resources around the globe can use this for data-driven PPE decision-making.
