The ultrasonic diffuser

The ultrasonic diffuser, also known as an ultra-sound diffuser or mister, is a somewhat technical but highly effective device.

It is based on the airborne suspension of a mass of water and essential oils when they come into resonance with a train of very high frequency waves (16 to 20 Mhz). This method of diffusion is carried out cold so as not to denature your essential oils and, above all, to preserve all their energetic value.

What's more, ultra-sound diffusion slightly humidifies the air around you, making it less dry and more breathable. Less powerful than a fogging diffuser, the mister is very quiet (the water splashes a little) and will still cover an area of around 30 m². There is a wide choice of ultrasonic models. The surface area covered/price ratio is often unbeatable.

If you want to diffuse essential oils for therapeutic purposes, forget the mister. Unlike nebulisation, the essential oil particles are not sprayed pure into the air, but coupled with heavy water particles in liquid form. The active ingredients of the aromatic molecules will therefore remain suspended in the air for less time before falling back, reducing the duration of the effects of the essential oils.

This method of diffusion is still ideal for enjoying the lovely mist that escapes and for creating a pleasant olfactory ambience.

How the Olaki diffuser works

The Olaki diffuser's misting is caused by the vibration of a ceramic pellet at a very high frequency, which triggers ultrasounds by its movement. The vibrations will then cause the water and essential oil molecules to react, mix and rise in very fine droplets, creating a very elegant mist. This is why the Olaki diffuser is ultrasonic by misting. This innovative technology allows cold diffusion of essential oils. To do this, the oils must be diluted in the water in the tank. But beware, diluting the oils in water inevitably attenuates their virtues. This is why, if you wish to diffuse for purely therapeutic purposes, we strongly advise you to use a nebulizer rather than a misting diffuser.

How is the OLAKI diffuser used ?

WARNING : Despite the safety device that interrupts the operation of the device, avoid leaving the device on when you are not using it or when the tank is empty. For a complete shutdown, unplug the appliance from the electrical outlet.

Maintenance and storage of the OLAKI diffuser

If the water contains too much lime, calcium or magnesium, it can deposit a "white powder" in the unit. If this scum is deposited on the membrane, it may prevent the unit from working properly.

The life of the membrane is limited (about 3000 hours). After some time of operation the amount of mist generated will reduce. This is normal wear and tear of the ceramic membrane.

We recommend :
1) Use demineralised water for each use.
2) Clean the tank every 2 days and the membrane once a week.
3) Change the water in the tank regularly, do not leave it for more than 2 days.
4) Clean the unit (see explanation below) and make sure that all parts are completely dry when not in use.

To clean the membrane and tank :
It is important to regularly clean the ceramic membrane and the surface of the appliance with a soft cloth or cotton swab soaked in white vinegar and leave for a few minutes.
- Do not press or scratch the membrane or the water level control sensor.
- Do not use cleaning agents to clean the appliance.
- Do not use a hard tool to scrape the surface.
- Rinse the base tank with clean water.
- Make sure that water does not enter the air vent and that the air vent is not blocked.

After cleaning and drying, store the appliance in a cool, dry place out of the reach of children.
