The COVID-19 pandemic has led to challenges in the steady supply of single-use masks (respirators) [1] and many hospitals are faced with using new types of respirators to avoid stock-outs. While certified FFP2/KN95 respirators have the ability to prevent airborne infections, like COVID-19, influenza or tuberculosis, the performance of the respirators depends on tight sealing of nose and mouth.
