A humidifier includes a base unit defining a reservoir for retaining a liquid. A liquid supply tank is also provided which is supported by and positionable within the base unit. The tank further includes an aperture defined by an aperture wall disposed on the top wall of the tank in order to permit the liquid to be introduced into the tank. The humidifier also includes a plug assembly having an outer diameter dimensioned for being insertable into the tank aperture. The plug assembly has a mechanism for increasing the plug's outer diameter. Such that when the plug assembly is inserted in the aperture, actuation of the mechanism for increasing the outer diameter urges the plug assembly against the aperture wall thereby sealing the aperture.
