Abstract
This disclosure provides a mask assembly for respiratory therapy, comprising: a vent for exhausting gas flow from an interior of the mask assembly, the vent comprising at least one vent hole; and a diffuser material defining a diffusing area sufficient to cover the vent hole and having a periphery. A region of the diffusing area of the diffuser material includes a localised joint region in which multiple fibres of the diffuser material are bonded or interlocked together. The location of the localised joint region is offset from the vent hole. Further embodiments are disclosed in which the shape of the diffusing material matches the shape of a vent hole array, or has other properties related to the vent hole array or the shape or other features of the vent.
