1. An electronic device, comprising:
a housing defining an internal volume;
a venting module in fluid communication with the internal volume, the venting module comprising:
a support structure;
a membrane; and
a porous member disposed relative to the membrane, the membrane and the porous member defining a fluid path, the porous member coupled to a mount that extends from the support structure into the fluid path, the mount retaining the porous member in the fluid path, a cross-section of the fluid path comprising a surface area of the porous member that is defined by a width and a length of the porous member, the fluid path extending from the internal volume to an environment external to the housing.
