ABSTRACT:
An air humidifier includes a water level detector that detects the water level in the water reservoir, and first and second light-emitting elements. The first and second light-emitting elements are selectively energized to emit light in response to whether the water level detected by the water level detector is at or above or below a predetermined level so as to permit quick visual inspection of the relative water level in the reservoir.
