I ordered the tabletop dehumidifier for my bedroom in lieu of an air conditioner because I cannot sleep with the noise a window unit generates.  It is whisper quiet on sleep mode and is about as loud as a general freestanding fan when not on sleep mode.  The lighting options are a plus, it helps determine the water level much better.  The water tank capacity is about ½ gallon.  There is an automatic shut off if tank is full which takes the worry away from overrun.  I’ve had the unit for 6 days and kept it running with windows and door shut to the room, it has been humid in New England and the dehumidifier has maintained a comfortable setting so far.
