Abstract
A humidifier has a base and a housing. The housing has a steam exhaust vent and a vaporizer. The vaporizer includes a heating element surrounded by a removable porous sleeve that protrudes downwardly into water within a reservoir of the base. The sleeve wicks the water including its minerals and impurities into contact with the heating element wherein energization of the heating element causes the wicked water to convert to steam that rises through the exhaust vent and from the housing during a humidification mode.

- a base adapted to removably receive the housing there-atop, and including a reservoir for receiving water from the tank and the porous sleeve;
- whereby,
- the porous sleeve wicks water from the reservoir including minerals and impurities therein into contact with the heating element, wherein energization of the heating element causes the wicked water to convert to steam which rises through the steam exhaust vent and from the housing during a humidification mode, and wherein the minerals and impurities remain within the porous sleeve.
