Abstract: A system for humidifying a gas, the system including a housing defining a humidification chamber through which a gas travels, and a humidification assembly adjacent to the housing. The humidification assembly includes a source of humidifying liquid and a porous wick for carrying the humidifying liquid from the source of the humidifying liquid into the humidification chamber. The wick separates the source of humidifying liquid from the humidification chamber such that the humidifying liquid flows through the wick before humidifying the gas traveling through the humidification chamber.
