A humidifier includes: a water tank for storing water; a heating water tank which is disposed below the water tank, and heats water supplied from the water tank; a humidifying water tank which is disposed below the water tank, and generates humidified air by using water supplied from the heating water tank; a connection pipe which connects the heating water tank and the humidifying water tank so that water stored in the heating water tank flows to the humidifying water tank; and a floating valve which is disposed in the heating water tank and controls a water level of the heating water tank, wherein a water level of the humidifying water tank is controlled according to a disposition of the floating valve.

A low cost medical humidifier for adding moisture to a patient air flow is disclosed. The humidifier comprises a water reservoir, a disposable evaporative wick containing a heater, a lid containing electrical contacts to engage the heater in the wick and airway connections. The wick heater comprises a PET film with aluminum tracks and a cover layer of PTC resistive ink. The heater is covered with paper to provide a water pathway via capillary flow. There is a capillary path from the water reservoir to the wick. The wick and heater are manufactured with printing and calendaring processes in reel to reel processes.
