Objecto W4 Hybrid HumidifierAn exquisite addition to the Objecto collection, the W4 humidifier takes our classic look up a notch. The elongated figure and subtle change in curvature ensure that the same even mist provides your space with the best air. The removable water tank allows the humidifier to run for approximately 20 hours and shuts the humidifier off when the water is gone. The timer lets you stay in control of its run time and fan speed.
