Portable, small and compact aroma diffuser. It offers the opportunity to enjoy the benefits of aromatherapy and chromotherapy freely wherever you want, both indoors and outdoors, thanks to the built-in rechargeable battery. The GISA aroma diffuser is silent, purifies the environment, reduces free radicals in closed spaces and releases pleasant aromatic fragrances. The cold vaporization process breaks down the essential oils into micro particles through the ultrasonic plate that vibrates more than a million times per second vaporizing the water and oil to disperse them in the air. This mist is easily absorbed with maximum benefits. Just add 3 or 4 drops of essential oil per 100 ml of water to benefit from the effects of aromatherapy and chromotherapy for the well-being of body and mind. The diffuser can be used only as a humidifier, and also only as a coloured lamp. The lamp can be adjusted with automatic color change or by selecting one of the 7 colors available in two shades. The built-in timer allows the most effective and economical use of essential oils (60min, 120min or continuous). When the water level reaches the minimum the diffuser switches off automatically.
