    摘要： An antiviral face mask is specified, comprising: - a filtering membrane, - a front housing with a recess in a front side, said recess being covered by the filtering membrane, wherein a cavity is formed between the filtering membrane and the front housing, - a through-hole arranged within the recess, said through- hole allows that a fluid flows through the cavity during operation, - a UV-C light source arranged within the cavity, said UV-C light source irradiating fluid flowing through the cavity during operation, - a rear housing with an opening, said opening being configured such that fluid flows through the filtering membrane via the through-hole into a space formed between the front housing and the rear housing, if fluid is drawn through the opening, - a flow sensor configured to regulate an emission intensity of the UV-C light source with respect to a fluid volume flowing through the through-hole per unit time.
