ADLER AD 7972 Humidifier White

Product Information

The AD 7972 Ultrasonic Humidifier is a device that uses ultrasonic high frequency oscillation principle to atomize water into ultra fine particles. These particles are then diffused into the air to humidify the surrounding environment, refresh the air, moisturize the skin, and improve health. The device features a water tank with a capacity to hold the water. It has a water filling lid (1) and a water tank cover (2) for easy access. The spray nozzle (3) helps to disperse the mist into the air. An aromatherapy container (4) is provided for adding essential oils to create a pleasant aroma along with the mist. The mist air duct (5) ensures even distribution of the mist. The device also has a display (8) for easy monitoring and control. For safety reasons, the device is equipped with a water shortage protection feature. When the device detects a lack of water, it automatically stops working to prevent any damage.
