How to use a diffuser

How should you use an EO diffuser?

First of all, ask yourself if you want to use a diffuser simply to perfume and sanitize a room or a spraying diffuser or perhaps a relaxing diffuser. There is a very big difference between a deodorising product and a diffuser. The first one only hides odours by perfuming a room. When doing this, the air remains polluted and you need to repeat the operation time and again. The diffuser, on the other hand, retains the benefits as well as the aromas of the essential oils while diffusing them in the room.

Once you have made your choice, make sure you really understand how the diffuser works so as to optimize its use. Therefore, your first task is to read the instructions carefully.

Ensure that the diffuser is placed in a strategic location in keeping with the orientation of the room and its size. You may want to try a few different places at first until you find the one place that is perfect for an even diffusion in the entire space. You can now pour the amount of essential oil needed with a little water if necessary.

Switch on the diffuser, adjust the setting in order to have a smooth and stable diffusion no matter what time of day and enjoy fully its perfume in your home. You also need to clean it regularly in order to avoid an accumulation of stains.


Is it beneficial to diffuse EO directly into my home?


It is an excellent way of sanitizing spaces and rid them of viruses and bacteria that reside within that space. In addition, it will take care of the occupants of that space in a most agreeable and efficient way. Even though an olfactive route, essential oils may prove to be immune-stimulant for some (ravintsara, tea tree or lemon for example). Others are very active on the central nervous system and are very helpful in overcoming stress (true lavender, mandarin, ylang-ylang for example).



How long can I allow the diffusion of essential oils to last?

Practically, it is suggested to diffuse 10 minutes every two hours, with a diffuser whose power is adapted to the size of the room.

The duration of diffusion and the flow rate chosen depend on the size of the space and the number of people present. In general, you should allow 2 to 3 minutes of diffusion per hour and per person.


Suggestions of usage:

– Create an internal ambience: 30 minutes in the early morning, 30 minutes at the end of the afternoon.

– Deodorize a room or to induce sleep and relaxation: 5 to 10 minutes when getting up and 5 to 10 minutes before bedtime.

– Break down a fever, reduce tiredness and tension, to get rid of germs: 5 to 10 minutes per hour.


precautionsWhat are the necessary precautions to follow when diffusing essential oils?



Use essential oils that are 100% pure and natural.

– Take care of the choice of essential oils (allergies, counter-indications).

– Some oils may show to irritate respiratory mucous, sometimes even they may be neuro-toxic if they are used pure for a length of time.

– Do not diffuse in the presence of children under the age of 3, pregnant or breastfeeding women, epileptic people, or people with allergies or who are asthmatic.

– Place the diffuser so as to have the diffusion occurring away from directly affecting people at the level of their face or eyes.

– Always keep the diffuser and the bottles of essential oils out of reach for children.

– Do not forget your pets. They too may be sensitive to the diffusion.


How many drops on EO should I put in my diffuser?

The number of drops of EO will depend on your choice of the diffuser. The intensity of the perfume depends on the quantity of EO added to the water in some cases.


For a nebuliser, the quantity of EO depending on the size of the room:

In a large room of 30 m² for example, you can use 4 to 5 drops.

For a smaller room such as a bedroom, you may find that 2 drops are enough.

For a mist sprayer, the quantity of EO in regard to the size of the diffuser:

     Diffuser size Drop quantity
100ml 3-5
200ml 6-10
300ml 9-12
400ml 12-15
500ml 15-20



Can I use a mist sprayer in aromatherapy?

The use in aromatherapy is more limited given that the EO are diluted in water. They are more used to produce an olfactive ambience which will increase in intensity in accordance with the length of the diffusion.

Are mist sprayers of EO really effective?diffuseur-ocelia

Mist sprayers are less effective than nebulisers. The microdroplets contained in the mist are made of water and a weak quantity of EO. These are heavier than those produced by a nebuliser and cannot, therefore, be propagated as easily.

Should I clean an EO mist sprayer?


A mist sprayer needs more care if you want to keep it longer. A regular cleansing (every 3 days) is needed to avoid the build-up of limescale on the ultrasonic tablet which reduces the effectiveness markedly.

To cleanse the mist sprayer: empty the water in the mist sprayer. With a cotton bud dipped in vinegar, rub the metallic circle at the bottom of the container.



Are nebulisers noisy?

Diffusing through a nebuliser produces vibrations coming from the pump that propels air. This generates a small sound that can barely be heard if you are at a fair distance of the diffuser. A little trick to reduce or even eliminate this noise: place a thick piece of material on top of the nebuliser.




Do nebulisers use a lot of EO?

Contrary to other diffusers, a diffusion by nebuliser does not require an addition of water and only lasts for about ten minutes. Some nebulisers have a built-in timer that renders the diffusion almost autonomous (diffusion for 15 minutes followed by an interruption of 30 minutes. This cycle is repeated three times and it then stops automatically). Such an intermittent diffusion will prove to be a saving of your essential oil consumption in the long run.

Are nebulisers hard to clean?

If you are using a nebuliser daily, you will almost never need to clean it.

The only time a cleansing is mandatory is when you haven’t used your diffuser for a long period of time. This cleansing will avoid the drying of essential oils in the diffuser which would consequently block the pump.

The process:

  • Empty the glass section completely (there must not be leftover drops of essential oils at the bottom).
  • Cleanse with a long cotton bud soaked in alcohol about once a month so as to avoid blocking the pump or pour 1 or 2 ml of alcohol at 90° in your diffuser and leave for about 2 minutes. Normally, this should remove any essential oil stains. If it doesn’t work, mix some alcohol with organic lavender essential oil.



What security measures should I take during the diffusion?Diffuser-stonelia

If there are children in the home, make sure they are not near the diffuser so as to avoid any contact with the ceramic surface which can be very hot.

This process of diffusion is not adapted to aromatherapy. If you are aiming at a synergy diffusion of essential oils to heal you, it will not be very effective because each oil will be diffused in an isolated manner depending on the degree of volatility. On the other hand, diffusion by ventilation becomes interesting when creating a purely olfactive ambience.
