The ultrasonic diffuser

The ultrasonic diffuser, also called ultrasonic or noisy is a somewhat technical but very effective device. It is based on the aerial suspension of a mass of water and essential oils when they resonate with a very high frequency wave train (from 16 to 20 Mhz). This mode of diffusion is made cold so that you do not distort your essential oils and above all keep all their energy value. In addition, ultra-sound diffusion allows to slightly humidify the ambient air, making it less dry and therefore more breathable. Less powerful than a nebulized diffuser, the heater is, on the other hand, very quiet (small water spray) and will cover surfaces of about 30 m2. There is an important choice of ultrasound model. The covered/price ratio is often unbeatable. If you want to spread essential oils for a therapeutic purpose, forget the heater. Unlike nebulization, essential oil particles are not projected pure in the air, but coupled with heavy liquid water particles. The active principles of aromatic molecules will thus remain less suspended in the air before falling back, thus decreasing the duration of the effects of essential oils. This mode of diffusion remains ideal to enjoy the pretty mist that escapes and to create a pleasant olfactory atmosphere.

Presentation of the Kaolia diffuser

Kaolia essential oil diffuser

The Kaolia essential oil diffuser has become a reference in the last few years as it combines both the performance of the latest generation of ultrasonic diffusion and the simple and sophisticated design of a Zen decorative object that fits very well into any interior.

It works on a technology of diffusion by water misting. A few drops of essential oils added to this water (3 to 5 drops) to diffuse their scents and benefits in your home. Moreover, the soft and subdued lighting thanks to the integrated leds and its openwork metal body will transform this diffuser into a real decorative object in your living rooms, inspired by Japanese Zen gardens. 

The benefits of aromatherapy and the elegance of wood

Lift the Kaolia's grille, pour water and a few drops of essential oils, touch the sensory buttons on its real oak wood frame and instantly enjoy a moment of pure relaxation.

The Kaolia diffuses your essential oils in a delicate mist of fragrance and is animated by a pleasant light ambiance with changing colours, which bring the final zen touch to this irresistible and authentic diffuser.

Its touch-sensitive buttons allow you to set a continuous or intermittent diffusion. Its water level sensor ensures an automatic shut-off when the tank is empty.

What is the diffusion mode ?

The Kaolia diffuser falls into the category of foggers (also called ultrasonic diffusers). The misting of the Kaolia diffuser is caused by the vibration of a ceramic pellet at a very high frequency which triggers ultrasounds by its movement. This is why the Kaolia diffuser is ultrasonic by misting.

Mon ancien diffuseur est tombé en panne et n'a pu être réparé. Après avoir discuté avec Quentin il m'a été offert un nouveau diffuseur car il était encore garanti. Je remercie PentyBio pour leur sens commercial et leur réactivité. Cette version carré est tout aussi efficace que la version ronde.



Parfait pour une ambiance cocooning et une diffusion douce et parfumée


Que pour la déco

Jolie lumière changeante, belle vapeur, mais par rapport à un diffuseur d'huile essentielle ne sent rien du tout



Style Japonnais et diffusion discrète et colorée
