The Zenbow is an easy-to-use aromatherapy diffuser with colour changing mood lights, simply add oil and water and switch for an instant aroma hit. As the diffuser will blend into any environment this makes the perfect gift. The Zenbow also works as a Mini Humidifier, Air Purifier and Ioniser Use with tap water and your favourite essential oil (natural), room fragrance oil (mood setting) or even perfume oil (decadent) for an instant aroma hit! For such a small carbon footprint, the stress relieving properties are huge. Advanced ultrasonic technology also removes the need of a heat source, making these diffusers extremely safe. For added peace of mind, the diffusers incorporate a patented auto shut off which is triggered when the water falls below the required level.
