This Aroma Humidifier & Diffuser is a compact and elegant device featuring a beautiful glass dome and lighting effects. It effectively delivers a relieving spray mist to dry air, making it perfect for your home or office. With a simple one-button operation, you can choose from four mist modes and a light button that offers a colour-changing mode with optional static colours. Utilizing ultrasonic technology, it diffuses essential oils using sonic waves rather than heat or burning, preserving the oils' beneficial properties. Add 3-6 drops of your favorite essential oil to reap the health and wellbeing benefits, such as promoting relaxation, improving focus, boosting moods, and aiding dry skin conditions. The 100ml water tank provides a run time of 4-5 hours, and it features four mist modes (1, 2, 3 hours, or continuous) and an auto shut-off function for safety when the water level is low or the timer is up. The separate light button allows you to select brightness and a specific color for aesthetic lighting effects, making it ideal as a mood-changer or night light for bedrooms and nurseries. This cool mist humidifier gently releases water vapor to increase air moisture. Measuring 24cm x 12cm x 12cm, it's perfect for any space and makes a great aromatherapy gift. Essential oils can help with muscle tension, aching joints, and respiratory conditions. Instructions for mist modes and light settings are included.
