Humidifier for a respiratory therapy device

A humidifier for increasing an absolute humidity of a flow of air to be delivered to a patient's airways, the humidifier comprising:

• a reservoir configured to retain a first volume of water;
• a humidifier chamber comprising:
• an outer housing including:
• a water feed inlet;
• an inlet portion forming an air inlet configured to receive the flow of air;
• and
• an outlet portion forming an air outlet for delivering the flow of air with increased absolute humidity;
• a humidifier wick positioned inside of the outer housing, the humidifier wick being configured to retain a second volume of water, the humidifier wick forming a path for the flow of air through the humidifier chamber, and the humidifier wick being removable from the humidifier chamber;
• a frame positioned inside of the outer housing and comprising:
• a wick remover engaged with the humidifier wick, the frame being removable from the humidifier chamber such that engagement of the wick remover with the humidifier wick removes the humidifier wick from the humidifier chamber when the frame is removed from the humidifier chamber;
• and
• an air flow baffle positioned within the path formed by the humidifier wick to lengthen a distance travelled by the flow of air along the path;
• a heating element positioned and configured to heat the humidifier wick to vaporise the second volume of water to add absolute humidity to the flow of air travelling along the path formed by the humidifier wick;
• and
• a delivery mechanism configured to deliver water from the reservoir to the humidifier wick via the water feed inlet.
