A humidifier for gases, for example for medical administration, may be adapted for insertion into a well of a heater for warming liquid in the humidifier. A seamless metal can defines a cylindrical wall and a closed bottom end, containing wick means for absorbing water and presenting it in dispersed form to gases flowing through the can. Transparent probe means extend into the can and serve as a liquid level control for preferably automatically controlling the liquid level in the can to be maintained in the lower one third of the can.
