                     We aim to rapidly fabricate membranous filter media against the COVID-19 virus while minimising
                     breathing resistance in respiratory applications.
                     Our design goals are to maximise COVID-19 filtration efficiency and minimize pressure drop (air flow
                     resistance) across the membrane so that the patient doesn't have to work too hard to breath.
