A humidifier includes a base defining a boiler cavity, a liquid supply being supported on the base and having a discharge opening communicating with the boiler cavity and adapted to maintain a given level of liquid therein. An evaporation unit is removably mounted on the base and includes an electrically energized heater projecting into the cavity and a magnetically operated switch. A float includes a magnet which activates or deactivates a switch. A vapor passage discharges the vapor from the cavity.
