An electric steam humidifier consists of a container defining an operating volume for holding a sufficient amount of water to provide steam for eight hours or more and, disposed within the container, a heating element for heating the water to generate steam. The container includes a base segment defining a portion only of the operating volume, and an upper segment defining another portion of the operating volume and further defining an aperture for escape of steam from the volume. The base segment and the upper segment are joined in a water-tight seal. The upper segment, in a first, operating position, extends vertically away from the base segment, to define with the base segment the operating volume. The humidifier, with the upper segment in a second, storage position relatively closer to the rigid base segment, defines and occupies a significantly reduced volume to facilitate storage and transport.
