A humidifier (5000) for increasing an absolute humidity of a flow of air to be delivered to a patient’s airways. The humidifier comprises: a reservoir (5110) configured to retain a first volume of water; a humidifier chamber (5200) comprising: an air inlet (5002) for receiving the flow of air; humidifier wick (5230) configured to retain a second volume of water and substantially enclosing a path in the humidifier chamber for the flow of air; a heating element (5220) in thermal contact with the humidifier wick; an air outlet (5004) for delivering the flow of air; an air flow baffle (5208) configured to lengthen a path of the flow of air through the humidifier chamber; and a water delivery mechanism (connecting to 5206) configured to deliver a flow of water from the water reservoir to the water retention feature. The heating element is configured to heat the water retention feature to vaporise the second volume of water to add absolute humidity to the flow of air. The humidifier wick is removable from the humidifier chamber. |
