Zusammenfassung:A respirator that includes a harness and a mask body that is air permeable. The mask body has a sinus region and a primary filtering region and comprises at least one nonwoven fibrous webs The sinus region of the mask body exhibits a resistance to airflow that is greater than the primary filtering region. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.
