Equate Ultrasonic Humidifier User Manual -

The Equate Ultrasonic Humidifier comes equipped with an automatic shut-off feature that turns off the device when the water tank is empty. Additionally, some models may include a built-in humidistat that allows you to set a desired humidity level. When the humidity level in the room reaches the set point, the humidifier will automatically shut off or reduce its output to maintain a consistent humidity level.
