A pump that compresses air and a glassware that is used to “burst” the essential oil particles from which a light “mist” will come out of the neck of the glass. This “smoke” is the micro-diffused essential oil. The flow of essential oil and air are both very strongly accelerated by what is called the venturi effect. This effect is produced by the shape of the two nozzles. The high speed of these 2 flows, as well as the angle with which they cross each other, creates a very strong dispersion of the essential oil particles which are thus propelled into the atmosphere with a strong kinetics and a very low weight. The ideal combination for perfect diffusion.
Please note: The shape of the glassware has no influence on the quality of the diffusion, your choice depends only on your taste.
The diffuser of essential oils by nebulisation is generally more expensive to buy but has a good longevity and excellent diffusion.
You may choose these models of diffusers if:
You want to diffuse essential oils for therapeutic purposes (disinfection of the ambient air, zen atmosphere, prevention of winter illnesses, etc.): nebulisation is in this case very indicated!
You want to give someone a beautiful gift: these are beautiful objects, often made of noble materials.
You want to diffuse over a large area: a nebulizer can easily “treat” 50m², and leave a background of odour on 100m².
There are two main types of nebulizers:
The 2 Pump Technologies for Nebulisation:
1/Diffuser with Membrane Pump.
The diaphragm pump used in the diffusers is identical to the aquarium pump regenerating the air in the water.
There are diffuser models with single pump or double pump, the models with double pump being more powerful.
The first diffuser models are more than 25 years old. Because of their design, they are generally very reliable (we have customers who have had their diffusers for 20 years), but unfortunately a little noisy (the electromagnet generates a humming sound).
Single pump model
These are models that are designed to be diffused in rooms of 30 to 40 m2.
Examples: Tsylia diffuser
Double pump model
These are models that are designed to be diffused in rooms of 70 to 120 m2.
2/Diffuser with Turbine Pump.
These are models that are designed to diffuse as much as possible in rooms of 100 to 150 m2.
The principle is identical except that the air is compressed by an electric micromotor. These models are reliable over time and are more powerful and quieter than membrane models.
Examples: Wood base diffuser as Daolia diffuser
The New Generation of Nebulizers.
There are also new generation diffusers, which do not have glassware. Simply clip on the essential oil vial and turn on the appliance to spread the aromas. As far as the diffusion settings are concerned, there are two main options on microdiffusers: power variation, to adjust the unit to the volume to be covered, and programming, to run it in cycles or turn it off after a certain diffusion time, so you can enjoy all the advantages of a microdiffuser (those mentioned above) without the disadvantages (cleaning). A real revolution in the field of diffusion.
Advantages of a Nebulizer Diffuser:
the most efficient in terms of technology and broadcast quality,
These diffusers are powerful and allow to quickly cover large volumes (up to 120 m² for a standard ceiling height of 2.50 m).
Diffusion is cold. 2 advantages to this: There is no degradation of the essential oils by heat and their particles are particularly well dispersed during their projection. They are therefore lighter and remain suspended in the air longer than with other technologies.
Micronisation allows essential oils to be fractionated on the glass wall and thus release a maximum of active ingredients and scents.
In addition to being essential oil diffusers, they are very beautiful decorative objects designed with noble materials such as wood and glass.
Disadvantages of a Nebulizer Diffuser:
This technology involves the operation of a pump that can generate some noise. The air expelled under pressure creates the Venturi effect and emits a vibration. And when you say vibration, you say noise. A nebulizer will therefore always emit a small hissing sound, not disturbing in a living room, but this makes its use more compelling in a bedroom or during a meditation session. But like smells, sensitivities to noise are unique to each person.
Glassware gets dirty and therefore requires maintenance. This is to be expected from time to time (once or twice a month depending on the frequency of use and the type of essential oils).
Another obstacle to the purchase of these models by nebulisation:
the price: It is clearly top-of-the-range in terms of diffusion technology, the glassware is fine, and manufacturers often use noble materials: wood, glass, bamboo, etc.
