If you are buying an essential oil diffuser, you may be wondering what benefits they have or what their effect is based on. Its use is rather holistic since there is currently no sufficient scientific evidence of the benefits of using an essential oil diffuser.

Many seek to balance the functions of the body and achieve harmony with the environment using the properties of plants. If you are one of those who value natural remedies and are concerned about your physical, mental and emotional well-being, the essential oil diffuser can be your tabletop ally. We’ll tell you why.

The most crucial diffuser oil

An essential oil diffuser is a safe way to use essential oils. It spreads necessary oil particles through the air so that people inhale them and benefit from their properties.

An essential oil diffuser is not the same as an air freshener or a humidifier: the diffuser’s function is to improve people’s physical and emotional state through aromatherapy.

Although essential oils are natural concentrates obtained from plants, their chemical composition is solid. It is advisable to be well informed of the properties of each one before using them since not all of them are suitable for being inhaled or used in an essential oil diffuser.

What is an essential oil diffuser?

An essential oil diffuser is a device that spreads necessary oil particles through the air in a room. When people inhale these particles, information is sent to the brain. It is expected to respond in a certain way depending on the properties of the oil used.

If essential oils concentrate the beneficial properties of plants, a vital oil diffuser helps spread these properties in the air of the room where it is located. In this way, the people who are inside the room will enjoy the aroma and the benefits of the essential oils by breathing, simply by being present.

What are essential oils?

Essential oils are highly concentrated extracts obtained from different plant parts (flowers, seeds, stems, bark or roots). They are received by steam dragging (distillation), getting a pure substance enriched with the regular benefits of the chosen plant.

Large quantities of raw material are required, so they are high-cost products. Despite their name, essential oils are not fatty substances and are called essential because they are based on the essence of plants.

What is the difference between humidifier, purifier and essential oil diffuser?

It is common to confuse an essential oil diffuser with a humidifier and vice versa since they work in a very similar way and are aesthetically similar. However, they are different devices. It is essential to consider this so as not to get confused when purchasing a product. In addition, there are air purifiers, which also have different functions.

Here we explain the differences between these devices:

. Humidifier: It humidifies the air and lowers the room temperature. It keeps the air cleaner and makes it easier for people to breathe. Can add Aromas but not essential oils, as they would spoil the device.

. Air purifier: this device cleans the air in the room. Using a fan and filters traps polluting particles such as pollen, dust mites, or tobacco remains. You cannot add flavours or oils to this appliance.

. Essential oil diffuser spreads micro particles of essential oils through the air. Oils can be applied alone or diluted in water. The diffuser does not create humidity but distributes beneficial substances through the air. By inhaling them, people can obtain physical, mental and emotional benefits.

How to use an essential oil diffuser?

It is recommended to use the manufacturer’s instructions. However, most essential oil diffusers (except traditional candle holders) work similarly.

. The diffuser opens.

. If the diffuser needs water, it is filled without exceeding the maximum line. If not, we go to point 3.

. Drops of essential oils are added to taste. That is, you can take as many bubbles as you want. Unrefined oils can be mixed with some neutral oil, such as olive oil, to make them softer to breathe and not dry out the environment.

. Once filled, the diffuser is closed, plugged in and turned on.

Depending on the type of diffuser, you can have different use programs; it is about choosing the one you want at each moment.

Specific uses of the essential oil diffuser

Although the use of an essential oil diffuser is not limited to a specific population, some particular situations and groups should pay special attention when using an essential oil diffuser.

During pregnancy

Pregnant women develop a significant activity of the olfactory nerves of the nose. Since essential oils are substances of excellent chemical concentration, they can activate solid physical responses in people. Therefore, it is necessary to take special care with the diffuser and use only those oils indicated during pregnancy.

The International Federation of Aromatherapists (IAF):

Has drawn up the following list of essential oils suitable for pregnancy: sandalwood, bergamot, orange blossom, black pepper, chamomile, sage, cypress, geranium, eucalyptus, juniper, lemon, grapefruit, tea tree, lemon, ginger, rose and lavender.

If you are pregnant and interested in using an essential oil not indicated on this list, we recommend that you first consult a pharmacist or an obstetrician.

Practising yoga or meditation

The use of essential oils during yoga practice is becoming more and more frequent. Both aromatherapy and yoga seek the individual’s harmony and balance with the environment.

The Association of Therapeutic Yoga endorses using the following essential oils to relieve muscle inflammation: balsam fir, lemongrass, mint. One of the Faculty of Pharmacy and Biochemistry of the University of Trujillo assures that inhaling some essential oils during meditation significantly reduces states of stress and anxiety.

. Children and babies:

During pregnancy, special care should be taken with essential oils in children and babies since they are more sensitive to chemical substances in general.

Studies of essential oil diffusers with children have focused on the benefits of aromatherapy in children with attention disorders or autism spectrum disorders. The results with these groups of children demonstrate:

. A greater capacity to concentrate and for a longer time when carrying out an activity

. Much more efficient interaction with the environment

. Reduced irritability in new situations

Animals and pets

Suppose you have pets. This section interests you. Animals have a sense of smell between 1,000 and 10,000 times more developed than people. Therefore, any scent that we add to our home can be a real nuisance for them.

“The United States Animal Poison Control Center warns that overexposure or ingestion of essential oils can cause animals to lose balance, depression or an extreme and lethal drop in body temperature.”

In addition, he makes the following recommendations to essential oil diffuser users who have pets:

. Never allow the animal to ingest essential oils.

. Keep the diffuser inaccessible to animals not to get burned by the steam.

. Use the essential oil diffuser for short periods and in a room the animal does not have access to.

How to know which essential oils to buy?

Essential oils are high-cost substances because large amounts of raw material are needed to obtain just a few millilitres. Low-priced essential oils are often not pure: they are usually diluted with non-essential oils (such as olive oil) or mixed with artificial chemicals.

To buy safe and quality essential oils, the John Hopkins and Children (USA) organization indicates that the label must include at least the following information:

. Name of the plant (for example, lavender)

. The Latin name of the plant ( Lavandula Angustifolia ).

. Part of the plant is used to obtain the oil (leaf, flower, seed, bark, and root).

. Country of origin

. Extraction method (distillation, pressure, etc.)

Purchase criteria

You have already seen the different types of essential oil diffusers that exist, and perhaps one has caught your attention. However, the important thing is that you find the one that best suits you, the use you want to give it and your lifestyle. Here are some points you should pay attention to before making your purchase.

. With water or without water

. Material

. Size

. Programmable

. Cables: yes or no?

With water or without water

This criterion is directly linked to the question “Where will I use this essential oil diffuser?”. Essential oil diffusers with water are indicated for large spaces, such as a store, an office or an open room. In addition to distributing the oils, the water will help homogenize the air in the different environments. For example, the air next to the refrigerator and the air next to the exit door usually have extra humidity and temperatures that this diffuser can homogenize.

On the other hand, for small rooms (less than 12 m) and poorly ventilated, it is better to use diffusers without water to avoid the formation of humidity and mould. They are also the best option if you want to treat a specific ailment since oil concentration will be higher.


The material is also an important criterion when choosing a diffuser. Whether for aesthetics or comfort, think about it before deciding.

. Wood: Wood is a porous natural element, so it will absorb part of the essential oil particles and end up acquiring the particular smell of your favourite oils. It is not a heat-conductive material, so you will be sure not to burn yourself if you get confused easily. It’s also not particularly fragile, so you’ll be able to move the diffuser around (and even travel with it) with no problem. In addition, the wood will never alter the properties of your essential oil.

. Ceramic: it is also a natural material and can be decorated in many ways. However, a ceramic essential oil diffuser can get hot and cause burns to the most unsuspecting. In addition, it is a fragile material that you do not want to take on a trip or move from one place to another. It may be a good option if you are clear about where you want to put the diffuser, and your idea is to leave it fixed.

. Plastic: although it is an artificial material, a plastic essential oil diffuser has several advantages: it can include LED light, turning the diffuser into a decorative element; you will be able to move it from place to place without problems, it will not break; it’s not a heat conductor, so you won’t burn yourself when you touch it (as long as you avoid touching the hot steam!). It is the best option to take on a trip.


The size to choose will depend mainly on the use you want to give it. If you’re going to enjoy the benefits of a non-stop essential oil diffuser, we recommend purchasing a large one, at least 300 ml. You probably don’t want to have to refill it constantly.

For the same reason, we recommend a large essential oil diffuser if you plan to use it in a large office or in a place where you receive clients: you will avoid having to change the oil when you have a visitor.

A small diffuser (less than 200 ml) will be helpful if you like to try different essential oils:

. You spend the charge already for the next oil. It will also be handy to have a small one if you plan to take it on a trip or from home to work.

. If you prefer to use the diffuser for specific situations (relieve a headache or nausea), we recommend a small diffuser.

. Remember that after each use of the diffuser, you must empty it. With a small diffuser, you will avoid wasting a substance as valuable as an essential oil.

If you are not sure, you can always get a medium essential oil diffuser and buy a different size diffuser when you know what you need from it.


To choose a programmable or non-programmable essential oil diffuser, you must be honest with yourself and choose the one that best suits you:

Programmable diffuser

. You’re good at technology

. You are clueless

. You think you will use day and night

. You prefer not to worry when you get home

Non-programmable diffuser

. You don’t get along very well with electronic devices

. You have a good memory

. You will only use it during the day

. You like to control every situation at home

Cables: yes or no?

Most of the essential oil diffusers that you will find on the market are corded, and there are still few that are battery or battery-operated.

Cordless diffusers are usually smaller than corded diffusers. They are designed as a travel alternative for rather specific uses. Its power and accuracy may drop as the battery wears out.

On the other hand, diffusers with cables are designed for regular use, in a specific location and “without taking them out for a walk” around. Therefore they are also larger.


Like any alternative therapy, essential oil diffusers have detractors and champions. Our advice is that if you are curious, give it a try. We have shown you only a small selection of all the essential oils that exist; some are attributed to extraordinary properties. The essential oil diffuser is possibly the most comfortable experiment with them.

We would love to know what you think of the article. Have we missed something? Has it helped you decide which essential oil diffuser to buy? Leave us your comments, and if you think someone might find them helpful, share them.
