Aromatherapy Diffusers

One important feature of alternative medicine is the benefits of aromatherapy, using essential oils and diffusers. It has become a popular way to relax, de-stress, and even help prevent sickness. Essential oils can also improve your mood and cognitive functioning.

An oil diffuser disperses the aroma and benefits from essential oils into the air, making it one of the easiest ways to maximize your benefits. There are many types of oil diffusers; some require electricity while others release the scent using your body heat only. It’s important to select the right one that fits your budget and use.

What is an oil diffuser?

This is a device used to spread essential oils in the air and let us take advantage of their benefits. Essential oils are non-greasy, yet, soft and soothing. They are nature’s helpful solution for the problems that chemicals, poor nutrition, and stress have added to our lives. It is important to choose quality oils to get the best results.

Oil diffusers/vaporizers can be used in the home, hospitals, hotels, lodges, health spas, and even cars. Some diffusers use heat to diffuse, and there are also those that use cold air.

Different types and their functionality

Nebulizing Diffusers

The nebulizing diffuser is one of the most popular models of diffuser available on the market. It works by atomizing the essential oils, and then circulates the fragrance into the air. It does not require any heat or water to be added to the oils, so they are delivered in their purest form. This is the best diffuser to provide a complete range of fragrance and benefits from essential oils.

It is made up of a base, the nebulizer, and a pump for spreading the oil into the air. This diffuser can be found in a lot of different materials such as glass, metal, plastic, ceramic, and wood.

Many of them have timers that enable you to set how long you want them to run for. Another feature found on some of the diffusers allow you to adjust the volume of oil that is dispersed. They are efficient in large areas where you need to create a therapeutic atmosphere quickly and efficiently. It is also very quiet.

One of the downsides of nebulizer diffusers is that, since they work so efficiently, if not monitored, they might produce too strong of an aroma. Similar to if someone put on way too much perfume and you can just smell it everywhere. It is recommended that you try out your nebulizing diffuser in short time periods when you first get it, so you become familiar with how it works.

Ultrasonic Diffusers

Otherwise called the humidifying diffusers one of the most popular types available.

In ultrasonic diffusers, no heat is used to separate the particles of your favorite essential oils This means that there is no change in their chemical component, making this one of the best diffusers for delivering the most benefits from the oils.

The ultrasonic essential oil diffuser works by using fast electronic frequencies to vibrate a disc under the liquid to mix and activate the oils. Often the oils are diluted with another liquid, usually water. The oils then are released and will spread throughout the room. Since the oils in the Ultrasonic diffuser is mixed with water, you will not have an overwhelming scent to worry about, like you might with the nebulizer.

The cloud created by this gadget is not pure oil; it has been joined with water, so the aroma is not so much increased but rather more mitigating when contrasted with that produced by the diffuser. This dispenses with the requirement for controlling the measure of fog discharged into the air by ultrasonic diffusers.

Ultrasonic diffusers come in various models and cost. You will find that some of the most expensive models have extra features that might be useful, such as shutdown timers and more silent functioning. The benefits of this type of diffuser is that no heat is involved, it uses little energy, is suitable for large rooms, and can be cost efficient.

Evaporative Diffusers

Evaporative diffusers have a small, flat fan rotating across a soft, sponge-like pad. You put a few drops of essential oils on the pad, and the fan scatters the scent into the room faster than it would normally.

There is another type of evaporative diffuser that doesn’t use a fan but relies on the air current in the room to diffuse around small areas.

Jewelry Diffusers

Jewelry diffusers are a type of evaporative diffuser and work using your body heat to warm up and activate the release of aroma from the oils. The most common type of jewelry diffuser is the necklace. You just put a few drops of oil onto the absorbent surface of the necklace and the aroma is released towards your nose.

These types diffusers are the easiest to transport since you are already wearing them. They are also silent, don’t need a lot of oil, and take no extra energy to activate.

Heat Diffusers

Heat diffusers are popular with people because they are silent. Even within this category, there are different types of heat diffusers.

  • Tea light diffusers have a small candle to provide the heat.
  • Electric oil diffusers are warmed using the heat from a light bulb.
  • Stone oil diffusers made from carved soapstone, are heated by warm water and your skin

Candle Diffusers

One of the most popular types of heat diffusers is the candle diffuser. Usually made of ceramic or metal, a candle diffuser has a bowl or tray that is heated by a candle under it to disuse the aroma into the room.

There are many options to choose from. Some are very affordable, and some cost a little more. Candle diffusers often come in beautiful models and are ideal for anyone who naturally likes candles but wants the added benefits of essential oils.

These are very easy to use but the drawbacks are candles can be a fire hazard, the area that oil is spread into is limited, and the use of heat might reduce the therapeutic benefits of the oil.

Clay Pot Diffusers

With these diffusers, the essential oil is poured into the middle of the clay pot and capped off with a cork. The pot absorbs the oil and transmits it into the air. You can adjust how strong the aroma is by adding more or less oil.

Clay pot diffusers come in many different shapes and sizes and are one of the cheapest options. They don’t need to use batteries or to be plugged in to work.

The main drawback of these diffusers is that you can’t keep a consistent level of aroma in the area. It is usually strongest when first applied and then weakens as time goes by.

What you need to consider

Now that you know how many options are out there, how are you supposed to choose the right one for you? Picking the best vaporizer for your home does not have to be a complicated process. It is normal to feel overwhelmed by choices and information when you first start looking. By breaking down what you want the process of finding the best diffuser for you becomes much more manageable.

Where will you use it?

Oil diffusers can be used in any room of your home. They can also be used in your office and your car. There are portable diffusers that you can take with you when traveling for your hotels.

Each diffuser will give a description of how big of a space they’re meant for. Take a look at what size space you’re going to put your diffuser, and narrow down your choice from there.

What type is best for you

From the list above, you should hopefully have an idea of the different options you can choose from. You want to make sure you get the diffuser that has the functions you want. The Ultrasonic and Nebulizing diffusers are the best for making the most of the therapeutic benefits of your oils, while the heat, evaporative and other diffusers might be more portable and better for brightening up the smell of a room.


All diffusers have different capabilities. Some are very basic; they only turn on and off. Some have continuous run features while others have intermittent sequence features. Many diffusers have ambient color led light rotations. When choosing your aroma essential oil diffuser, keep in mind how you will be using it. If using it in your bedroom at night time, you may not want all the colors of a rainbow circulating. If using in a small area, you may want an occasional feature.


As mentioned earlier, all diffusers are not created equal. However, that does not mean that you need to break the bank to find the best diffuser for you. It is the best to start thinking about what kind of diffuser you want, how big of a room you’ll be using it in, and what you feel comfortable paying.

Once you get a good idea of what you’re looking for, you can narrow your search to the diffusers that meet your criteria. Remember, just like with essential oils; you get what you pay for. It might be worth spending a little more on a well-known, trusted brand instead of saving a few bucks for something that won’t last as long.

Ask for advice

If you are new to essential oils or just don’t know what will work best for you, just ask! Seek help from a friend that uses essential oils, people in the shops, or even online. Don’t be shy about asking for a presentation or explanation of the products. By getting all the information you can, you can best choose the one that will work for you.

Also make sure you read the reviews posted on our site!
