Abstract
A combination evaporative/warm mist humidifier comprises a base having an evaporative cavity and a warm mist cavity disposed therein for retaining a liquid. A lower supply portion of a wick element is disposed within the evaporative cavity and an upper evaporative portion is disposed thereabove. The wick element is adapted to provide liquid flow by capillary action from the lower supply portion to the upper evaporative portion. A housing having an evaporative chamber and a warm mist chamber is removably mounted on the base. The evaporative chamber is disposed above the evaporative cavity and is adapted to receive the upper evaporative portion of the wick element. A selectively operable blower assembly is provided in the evaporative chamber for inducing air flow through the upper evaporative portion of the wick element to evaporate liquid content therein and to discharge the evaporated liquid content from the evaporative chamber into the surrounding environment. The warm mist chamber is disposed above the warm mist cavity and a selectively operable heating element is disposed within the warm mist cavity for inducing evaporation of liquid contained therein. The evaporated liquid vapo…
