The nebulizer diffuser

The micro-diffusion diffuser, also known as a nebuliser, is still the best way to make the most of the therapeutic benefits of essential oils.

The principle is simple and effective. A pump sends air into a glass jar containing your essential oils. The air expels and bursts the micro-particles of oil inside the glassware via the giffard system. A smoke will then form (like a fog), charged with millions of fine particles of essential oils. So fine that they remain suspended in the air for a very long time. For products that are less sensitive than essential oils, the easiest way to create an aerosol is often to heat the liquid.

But how do you create a fine dispersion of essential oils without heating them ? Nebulisation diffusers all use 2 nozzles positioned at right angles to each other. One conveys the essential oil from the reservoir vertically, the other a very rapid flow of air horizontally. At the point where these 2 nozzles meet, the impact is very strong and generates the famous aerosol of essential oils. Not all the essential oil in the flow is nebulised, and the remainder falls back naturally into the reservoir.

There are 2 types of nebuliser : with glass or plastic nozzles

- Modern but less common, some nebulisers dispense with glass in favour of a polymer nozzle that plugs directly into your bottle of essential oils. They are generally a little cheaper, easier to maintain and more robust.

- The most common, with a blown glass system. They have the advantage of being beautiful, made of noble materials, and letting us admire the live nebulisation process. They are, however, susceptible to breakage. Glass is often preferred to plastic for a beautiful room in the house.

Micro-diffusion diffusers work by cold diffusion, so the essential oils remain unaltered and retain all their benefits.

What is the diffusion principle ?

The Walia diffuser is a nebulization diffuser (also called micro-diffusion). Cold nebulization is a very efficient process for diffusing essential oils into the atmosphere. It diffuses all the essential oils while retaining their benefits and properties, without changing the chemical structure and without overheating. The compressed air transforms the oils into aromatic micro-particles which, in the form of mist, escape through the dedicated outlet of the device, thus perfume the ambient air.

Zoom on the Walia diffuser

From its height of 18 cm, the Walia diffuser is a discreet, compact and designer diffuser.

Ideal for covering living rooms up to 100 m³, it will have its place in waiting rooms, medical practices, commercial shops.

It works on batteries or on its electric charger, so it does not require major installation work.

Its internal clock and its programming via the LCD screen on the front is its real asset. It is thus possible for you to program the ranges and the broadcasting time for each day of the week. Once the programming is done, let it do its job without worrying about it. You just have to remember to fill the bottle with essential oils and change the batteries from time to time (if you choose to operate it with batteries). For example: on the basis of use for 10 hours a day, a simple set of batteries will allow it to operate for 26 days on the basis of 3 seconds of diffusion and 100 seconds of pause. 70 days for 3s ON / 300 OFF, 130 days for 3s ON / 600s OFF, 228 days for 3s ON / 900s OFF.

Efficace et simple

Fatiguée de rempli d huiles essentielles des diffuseurs par capillarité qui ne sentent plus au bout de quelques heures, je me suis orientée vers ce diffuseur automatique. Franchement génial. Je ne comprends pas pourquoi les diffuseurs grand public ont si peu de fonctionnalités et de réglage. Seul ce diffuseur professionnel m’a offert la flexibilité de configurer des plages horaires des jours et la fréquence des vaporisation. Je l’utilise dans des wcs de qulques m2 et c est parfait. Genial!
