Our Ultrasonic Malibu Diffuser is your choice for Aromatherapy on the go. Take it in your car or anywhere you have access to a USB. It is small, portable, and your best diffuser for traveling. Having a diffuser at your disposal is convinient and exactly what you need. As with all our ultrasonic diffusers, they do not use heat. Instead it produces high frequencies to create vibrations that vaporize the surface of water dispersing it into the air. These micro molecules being released carry negative ions that adhere to dust particles thus purifying the air. Combining that with the beneficial properties from pure essential oils, you create a healthy therapeutic environment for you to relax and enjoy.
