The Ionmax Serene preserves the aromatherapeutic benefits of essential oils and blends, and is suitable for medium rooms.

Ultrasonic diffusion

Traditional oil burners rely on heating water to disperse essential oils. This is achieved with an element or open flame and can alter the delicate chemistry of pure essential oils or blends, potentially minimising their aromatherapeutic benefits as well as changing their scents.

The Ionmax Ion138 Serene Aroma Diffuser uses heat-less ultrasonic vibrations which break down water molecules and infuse them with your chosen essential oil(s). The infused water is then vaporised into the air (with aromatherapeutic properties retained), ensuring you get the most of your favourite oil or blend every time.

Works quickly and safely

The Ion138 starts working incredibly quickly - at the touch of a button, it will produce a fragrant microscopic mist within seconds. It is equipped with an auto switch-off function when the water tank is empty.

As the Ion138 does not produce any heat to diffuse essential oils and does not have any dangerous open flames, it can be left on overnight and safely used around pets, children and the elderly.

More than just an aromatherapy diffuser!

The Ion138 doesn't only diffuse essential oils or blends, it also boasts an ionising and air purifying function. It has a built-in soothing LED light which can be set on one of three colours or on smooth colour-morphing to create a peaceful, meditative atmosphere.

The convenient alarm function will sound for 60 seconds before switching on the Ion138 and LED lights on automatically - take advantage of this feature to wake up to bright and fresh essential oils or blends!

You can use the Ion138 to:

  • Diffuse essential oil blends in your workplace to improve mental clarity and concentration.
  • Improve sleeping and respiratory conditions with specific blends at the onset of cold and flu symptoms.
  • Promote an atmosphere of calm in your house especially around children and pets.
  • Wake up with fresh and uplifting essential oils or blends in the morning.
  • Relieve mild anxiety and promote relaxation.
  • Ionise and purify the air, removing bacteria, viruses and moulds.
  • Refresh and deodorise the air.
