1. A humidifier comprising:
a housing having;
a top side with a steam exhaust vent and a fill opening there-through,
a tank adapted to receive water through the fill opening, and a one-way fill valve to allow the water downwardly through the fill opening but otherwise close the fill opening; and
a vaporizer comprising a heating element surrounded by a removable porous sleeve, the sleeve protruding downwardly from the housing and in fluid communication with the steam exhaust vent;
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.
