If you're looking to buy a good quality essential oil diffuser, have a look at this list.At a time when most of our household and beauty products are riddled with chemicals, essential oils are fast becoming all the rage amongst health-conscious individuals.

I’m sure most of us have driven by a forest and have found the freshness of the air highly appealing.

I tend to take a deep breath to fully experience the wonderful fragrance of natural plants like lavender, jasmine and peppermint. This always has a positive effect on me in the sense that it gives off a general feeling of good health and wellness.

So, how can we experience these healthy benefits at home?

From my knowledge, an aromatherapy diffuser is the only machine that remotely comes close.

But how does this device actually work?

Well, essential oils are carefully extracted from plants through various processes such as distillation. This means that the characteristic fragrance of that particular plant has been captured.

There are several advantages of these substances including aromatherapy and these will be discussed in detail a little bit later.

An oil diffuser does exactly what the name suggests – it releases a mist and fragrance of your favorite blend through the process of diffusion.

Not only will this expose you to a pleasant fragrance, it’ll also promote the overall health of your body by inducing relaxation and keeping stress away.

If you’ve made up your mind about buying such a device then you need to try and do more research. This will not only provide you with advice on how to maximize the benefits of an air diffuser, but it’ll also allow you to pick the most appropriate product for your needs.

Within this guide, we’ve aimed to provide detailed guidance on the entire subject.

We’ve also personally tested a huge number of products and have revealed the results below. These have been reviewed in detail and compared to one another.

What are the Benefits of using an Essential Oil Diffuser?

These are just some of the benefits of an ultrasonic essential oil diffuser.Aromatherapy is one of the major known benefits associated with this strategy.

In the past, this has been used as a means of alternate medicine to improve the mood and general wellbeing of a person. It’s a well-known fact that there are lots of different oils, all of which have different therapeutic benefits.

For example, peppermint can be used boost your energy naturally while lavender has the ability to relieve stress!

The best thing about this is that you can create a blend of your favorite oils and put this through the aromatherapy diffuser to enjoy a host of different effects.

Antibacterial and antiviral properties are commonly exhibited by essential oils. In fact, these substances are completely pure and have very little or no foreign particles. This will ensure that you breathe pure fresh air when you’re at home.

The disinfectant effect can boost your immune system and improve your overall health. However, you might need to get a nebulizing diffuser over a standard one to maximize this.

In addition to these advantages, there’ll be a naturally pleasant scent inside your home and this will be sufficient to induce an upbeat mood on its own.

Picking the Right Aromatherapy Diffuser for Essential Oils

An aromatherapy essential oil diffuser is a very good device to have in your home.There are various types of these devices available to buy and their method of use will depend entirely on this. It is incredibly essential that you use these in the most appropriate manner.

Nebulizer and ultrasonic diffusers are the most popular when it comes to diffusing essential liquids. The nebulizer is certainly the one that performs better in the sense that the effect is longer lasting and has better health benefits.

We won’t have to use any water – in fact, we can only use a few drops of pure essential oil. This will produce a strong concentration of the liquid to be diffused.

A good quality nebulizing diffuser also won’t have any lights and would be perfect for use at night.

In comparison, an ultrasonic oil diffuser uses ultrasonic vibrations to break the liquids into tiny particles, which are then dispersed throughout the air.

This type is also cheaper than a nebulizer and uses up less oil due to the dilution with water. However, this ultimately means a low concentration being diffused.

Despite this, an ultrasonic diffuser can also function as a humidifier when used with water only. In this case, it’ll efficiently moisturize dry air in your home thereby, being particularly advantageous in the winter!

Before beginning your research, there are some questions you need to answer. These will ensure that you pick the right product.

Firstly, you need to estimate the area that you’ll be using the machine in. Do you need the aroma to fill your bedroom or a much larger space?

Some people also find it quite useful to have a timer on their aroma diffuser. While most of these devices will shut off automatically, not all will have timers built in.

In addition to this, the budget is also an important consideration. Nebulizers tend to be more expensive than ultrasonic devices so you need to weigh the advantages against the disadvantages of both product types!


By now, you should be a bit more certain about the use of an essential oil diffuser to eliminate stress and promote wellness in general. There are simply no arguments against the use of these devices for healthy living.

In searching for the best performing products, we went through a host of nebulizer and ultrasonic devices. Both of these types have their own benefits but the most essential factor is the efficiency of a nebulizing diffuser.

When it comes to this type, the Aromis Orbis Nox Merus was the best performing model. It provides a perfect balance between aesthetics and performance.

All of the ultrasonic devices were associated with similar performance levels. However, the Riverock was the most visually appealing model though this will be a personal choice for you.
