A vent arrangement for a mask system including a mask component (e.g. elbow assembly 580) and a mask vent (540) provided to the mask component. The mask vent is recessed within an interior of the mask system. The mask vent includes a plurality of vent holes (542) each extending through a thickness of the mask component and each including a vent exit, and a continuous side wall (550) structured to surround the plurality of vent exits of the vent holes so as to enhance dispersion or diffusion of exhaust vent airflow from the vent exits.
