Easily connect the diffuser to your smartphone via Bluetooth and the integrated speaker will stream the music your mood dictates.

3 in 1

As well as a speaker and diffuser, it also functions as an air humidifier, so if you aren’t in the mood for aromatherapy, simply fill the tank with water alone. At the touch of a button, your diffuser will humidify to just the right level by releasing a fine mist into the air. Ideal levels of humidity have a beneficial effect on the airways and can help ease problems with dry skin, eczema and asthma. Easily adjust the amount of mist to suit your needs.

Long-lasting, quiet, simple

With a 400 ml water tank, the diffuser will last for up to 10 hours of continuous operation. And as it’s whisper quiet, you can even leave it on at night without disturbing your sleep. When it detects low water levels, the humidifier switches itself off and there’ll be no risk of short circuiting or overheating. Intuitive controls make the device easy to operate. With 3 dedicated buttons you can easily switch the diffuser on and off, set the timer and set the desired mist intensity or lighting colour.
