Feel The Healing Power Of The Dark Side. Darth Vader remedies room dryness, and fights mold and mildew with anti microbial technology from a humidifier built into his helmeted head. The stoic Sith Lord employs ultrasonic technology to dispense a gentle soothing mist rather than the loud fans of lesser civilizations that can be heard far, far away. His armored body conceals a 1/2-gallon water tank that humidifies a room for up to 12 hours with 10 moisture settings, and an auto-off function for safety. Lord Vader also incorporates a nightlight to ensure a room does not slip over to the Dark Side.
