Abstract
A heat and moisture exchanger for a patient interface, comprising a nonwoven composite formed from a fibrous material having a first planar surface, an opposite second planar surface and a sidewall positioned between the first planar surface and the opposite second planar surface; and at least one vent on the first planar surface, the at least one vent extending at least partially toward the second planar surface, and a wall of the at least one vent being formed from the fibrous material; wherein the nonwoven composite is permeable to air; and wherein the nonwoven composite including a first impedance and the vent including a second impedance less than the first impedance to allow a flow of gas through the first planar surface.
