What Is a Diffuser?

A diffuser is a small device that vaporizes liquid containing tiny particles of essential oil into the air. As the liquid evaporates into the air in your home, the aroma spreads to create a beautifully smelling space. This is essentially how a diffuser works, although not all diffusers are the same, as you will see when you keep reading.

What Kinds of Diffusers Are There?

As explained earlier, diffusers are relatively simple appliances. Nonetheless, there are a handful of different models that function in various ways. To explain the differences more clearly and make your decision easier, we’ve put together the following table.

Type Function
Electric diffuser with water This model works by way of ultrasonic vibration. It has a small tank in which you can mix the water with the preferred essential oil. This kind of diffuser utilizes a vibrating mechanism to dispense the aromas into the air as mist. It’s important to use the correct balance of water and oil to produce a perfect aroma.
Electric diffuser without water This kind of diffuser features a pumping system. The oil is not mixed with water, so the device emits the liquid into the home as steam. These are also called nebulizer diffusers. The aroma produced with this kind of diffuser is often more intense because the essential oils are not watered down.
Non-electric diffuser This kind of diffuser is the simplest. They work through the use of burning candles or charcoal tablets to release an aroma into the air. They are the cheapest kind of diffuser, but they require a good deal of caution as they can cause accidents, especially if there are children playing nearby. They are commonly referred to as scent burners.

Is a Diffuser or a Burner Better?

You may be thinking that a non-electric ‘scent burner’ is the best option, since it’s the most affordable and easiest to operate. But the truth is that if you want to really take advantage of essential oils and create an environment with a great smell at home, the best options are probably the electric diffusers. Not only do they produce a better aroma, but they also create a more balanced scent distribution as compared to the highly concentrated smell emitted from burners.

Robert TisserandAromatherapy Expert

“Aromatherapy is a caring, hands-on therapy which seeks to induce relaxation, to increase energy, to reduce the effects of stress and to restore lost balance to mind, body and soul.”

How Do I Use a Diffuser?

Now that you’re familiar how the different kinds of diffusers function, you probably want to know how to actually use one at home. The non-electric devices are very simple. Just put the essential oil on top and active or light the source of heat below. The other two kinds of diffusers, the electrical options, are a bit more complicated. Here’s a brief guide:

  • Instructions. The first thing you should always do when you first use an appliance is read the instruction manual. This allows you to learn about all the different functions and settings available to you.
  • Open the diffuser. The next step is to open the diffuser and take away the top of the device. You should also remove the lid from the water tank, if you’re using a diffuser with water.
  • Water. If you’re using a water diffuser, it’s now time to pour water into it. We recommend using distilled water to prevent limescale buildup. Be sure not to exceed the maximum capacity of your water tank. If you need to mix the essential oils with the water, closely follow the instructions to find the right balance.
  • Cover the diffuser. Put the diffuser top or cap back on and be sure it’s shut properly.
  • Plug in the diffuser. After you’ve poured the water inside and closed the diffuser, you can plug it in. If it operates via battery, check that the battery is fully charged.
  • Turn on the diffuser. Now it’s time to turn it on, and you’re ready to take the final steps of this setup process.
  • Choose the program. Most diffusers offer a handful of programs and settings. You can usually program the amount of time that the vaporization lasts, select the color of the light or even the intensity of the mist formed. The most advanced diffusers have a remote control so that you can do all this from the comfort of your couch or bed.
  • Essential oils. The final step is to add the essential oils. If you’re using a water diffuser, then the oils should already be mixed in. If the diffuser doesn’t use water, you’ll have to determine where to add the essential oil. Follow the instructions to figure out what kinds of oil can be used and what quantity is best.

How Much Does a Diffuser Cost?

As with most electric devices, you’ll find a wide range of prices on the market. Usually the price of a diffuser falls between 15 and 40 dollars. The cost of the diffuser will depend on the functions it offers, in addition to the brand and specific design. Always try to pick a product that gives great value for the best price. It’s also important to consider whether you plan to use the diffuser all the time or only now and then.

What Are Essential Oils Used For?

Essential oils are a kind of liquid that emits a pleasant aroma. They are extracted from flowers, leaves, wood, seeds and roots. They don’t only help your home smell nice, but also provide other beneficial properties. There is an essential oil for just about any situation. See the table below to learn more about different oils and their uses.

Oil Properties
Jasmine Helps reduce stress and ease sleep-related issues.
Lavender Helps with muscular pains related to stress and helps with sleep.
Cinnamon Helps to calm emotions, limit fatigue and improve mood.
Black pepper May be useful if you’re trying to stop smoking, and it helps with anxiety management.
Almond Helps boost serotonin levels and deal with pain.
Bergamot Improves disorders related to anxiety or depression.
Nutmeg Works well as an aphrodisiac. It also helps with depression.

What Are the Pros and Cons of Diffusers?

By now, you’re familiar with the different features diffusers offer. But in order to make a successful decision, there is some additional information for you to know. Here, we review the primary advantages and disadvantages of this device:

  • They help you benefit from aromatherapy
  • They are reasonably priced
  • You can enjoy a better smell in your home
  • Some models can be complicated to use
  • You have to find the right place for them in the home
  • In some cases they are bought and rarely get used

Shopping Criteria

We can’t finish this great guide without first going over the key factors you should take into account when making your decision on which diffuser is right for you. By following the following shopping criteria, we’re sure that you’ll find the diffuser that you’re looking for.

Power source

It’s important to consider the power supply of the diffuser. Electric diffusers generally have two power sources. The most common option is plugging the device right into an outlet. This can be a limiting factor, however, as you’ll always need to find an outlet to use. The other common power source is batteries. We recommend picking a diffuser that uses batteries, preferably the rechargeable type. With batteries, you can move the diffuser around the house as needed without worrying about accessibility to an outlet.


There are oils that offer only a pleasant smell, while others offer health benefits.

Always aim for a diffuser that’s simple to use. Additionally, a diffuser with a remote control is much more convenient. Another interesting feature you may want is a timer to program when the diffuser should turn off. Some diffusers also offer settings to regulate the intensity of the aroma, which can be very beneficial. The devices that turn off by themselves when the water or oil runs out are particularly innovative.


The capacity of the tank is another important factor, as it determines how long the diffuser can run without being refilled. Usually the capacity of a diffuser is around 300 milliliters, but there are models with capacities that are larger or smaller. We suggest avoiding any tanks that are smaller than 300 milliliters. That’s because larger diffusers are more durable and are able to disperse aromas for longer. Bear in mind that the larger the tank capacity, the larger the overall dimensions of the diffuser.


Most essential oil diffusers feature colored LED lights. Don’t forget that the color emitted by your diffuser can also have benefits. Using colored lights is the basis of chromotherapy, which states that light can be helpful for certain diseases or ailments. We recommend picking a diffuser with colored lights that you find calming.


There are so many designs available that you’ll easily find one that suits your unique style and decor.

Some medical practitioners say that essential oils have the ability to improve quality of sleep.  If you plan to use your diffuser in the bedroom at night, look for an ultrasonic diffuser. This kind of diffuser emits as little noise as possible so that your sleep won’t be interrupted.


A diffuser provides you with the best aromas in your home and gives your house a sense of identity. They work by utilizing essential oils, which have a number of benefits. Most diffusers are very easy to use and affordable. We recommend choosing a diffuser with a timer so that you can easily control its operation. A remote control will also contribute to ease of use.

Another aspect of diffusers that you should take into account is the color they emit. Not only will the diffuser be more pleasant and decorative with a nice color, but you can also benefit from the feeling of a certain color in your home. Try to look for a quiet device so you can use it at night while sleeping. And, as always, look for a product that gives you the best value for money.
