The control feature was re-engineered to address certain noises generated in its first version. This effort is to ensure a consistent temperature difference between the water and ambient air, minimizing condensation in the tubing ("rain out") and keep the humidification level constant throughout the night.

Comes with a detachable, dishwasher safe water chamber for trouble-free maintenance. Open the chamber with the always available Extraction Tool, stored on the humidifier.

Features a rotary button that allows you to adjust heating level along with separate Power On and Heater On indicator lights. When the Heater Plate Switch is pressed against the water chamber, the orange heater indicator light acknowledges that the unit is ready for use.
