چکیده
The SARS-CoV-2 pandemic resulted in shortages of production and test capacity FFP2-respirators. Such facemasks are required to be worn by healthcare professionals when performing aerosol-generating procedures on COVID-19 patients. In response the high demand short supply, we designed three models that suitable for local production. As these should meet requirements an FFP2-certified facemask, newly-designed were tested filtration efficiency filter material, inward leakage, breathing resistance with custom-made experimental setups. tests, benchmarked against a commercial FFP2 facemask. facemask’s material was also coronavirus-loaded aerosols under physiologically relevant conditions. This multidisciplinary effort design requirements, which can produced at facilities.
