In this guide, you’ll discover how to choose your diffuser, which essential oils to use to purify a room or promote sleep, and how to enjoy all their virtues safely, even with children. Breathe easier, sleep more soundly, relax or boost your concentration: aromatic diffusion is a simple, practical and tremendously effective method.
Understanding essential oil diffusion
What is diffusion and how does it work?
Diffusing an essential oil of your choice releases its aromatic molecules into the ambient air. These are then breathed in and interact with our limbic system, the seat of our emotions, as well as with our respiratory tracts. Depending on the method used, they are transformed into micro-droplets or micro-particles for slow or intense diffusion.
Why diffuse an essential oil?
Diffusing an essential oil allows :
Purify the air in the home (antibacterial, antifungal)
Naturally perfume your home
To promote relaxation or, on the contrary, tonus
Supporting immunity and respiration in wintertime
Diffusion methods
With electric actuator
1. Ultrasonic misting: a silent, gentle and aesthetically pleasing method of diffusion. It mixes water and essential oils to create a fine, fragrant mist.
2. Nebulizer diffuser: powerful, water-free nebulizer propels pure essential oils for maximum therapeutic effect.
3. Soft-heat diffuser: ideal for light air diffusion. Less intense, but quiet and economical.

Diffusing without a diffuser: natural alternative methods
On a cloth or cotton pad: place a few drops on a handkerchief close to you.
On a radiator or in a bowl of hot water: for gradual evaporation.
On coarse salt, a pine cone or porous pottery: simple, aesthetic and effective methods.
And with a humidifier?
Some humidifiers accept essential oils. Always check compatibility. These devices provide discreet, but less concentrated diffusion.

The real effects of diffusion on air and health
What science has to say about EO air purification
Certain essences such as tea tree, lemon essential oil and eucalyptus have demonstrated antibacterial and antiviral effects. Studies show a reduction in certain airborne bacteria after diffusion of these essential oils.
Is it possible to measure the effectiveness of distribution?
Yes, there are indoor air quality sensors (VOCs, particles, humidity) to visualize the impact of diffusion. Tools such as AirVisual, Foobot or Netatmo provide useful results.
Diffusion & emotional well-being: adapting oils to the present moment
Which essential oil for which mood or emotion?

Evening: 10 min with relaxing essences, soft light and Zen music
Frequently asked questions (FAQ)
Can I broadcast all night long?
No, it’s best to keep it to 15-30 minutes, especially before bedtime. Prolonged diffusion, especially during the night, can saturate the room and cause headaches or respiratory tract irritation. Prefer a short diffusion just before falling asleep to promote relaxation without overexposure.
Can we broadcast with children or pets?
Yes, but with extreme caution. Some essential oils are toxic for young children, babies and pets (especially cats and dogs). Opt for gentle essential oils such aslavender essential oil or sweet orange, and diffuse only briefly, in well-ventilated rooms, without the direct presence of children or pets during the diffusion.
Can all essential oils be diffused?
No, far from it. Some essential oils should be avoided, as they are dermocaustic, neurotoxic or irritating to mucous membranes. Cinnamon, sage or clove, for example, should never be diffused pure. Always check contraindications before use.
