Researchers from the Electrochemical Innovation Lab (EIL) led by Professors Paul Shearing and Dan Brett (UCL Chemical Engineering) have teamed up with the Royal National Orthopaedic Hospital and the UCL Division of Surgery & Interventional Science to better understand the breathability and the filtration capabilities of three common face masks. Modifications to the current N95 masks are proposed to develop the next generation mask.

This COVID-19 related investigation was established in consultation with Prof Rebecca Shipley (UCL Institute for Healthcare Engineering). We have made the data freely available to the scientific community and the general public to help develop better face coverings and aid wider public understanding. The result was published on Communication Materials.
