Have you always wanted to experience the calming sensations of aromatherapy from the comfort of your home?

An essential oil diffuser can give you exactly that benefit. Infuse your home with the scents you want at the price you want.

Let us show you everything you need to know with this complete guide to the best essential oil diffusers including some objective, impartial reviews.

What Are Essential Oil Diffusers?

The word diffusion refers to the method of spreading essential oils throughout a room with their natural aromas.

An essential oil diffuser is a remarkably simple but efficient method of accomplishing this job.

There are a variety of diffusion methods but we are going to address the humidifier style.

These particular devices work by continuously feeding the room with the soft vapors of oils. This provides you with a pleasant scent with healing powers previously only encountered at a spa.

As well as a beautiful fragrance, the oils inhaled can also deliver you nerve-calming benefits and are great for overall health.

Whether you want to relax, meditate or enjoy a sound night’s sleep, essential oil diffusers are versatile and useful pieces of kit.

Always look for essential oil diffusers that have an anti-bacterial function. Bacteria can potentially grow in these devices due to moisture so it is best to avoid that in any way possible. Breathing in bacteria can have adverse effects on your health.

However, don’t worry… We are here to lead you. We outline only the best essential oil diffusers and present some neutral, honest essential oil diffuser reviews.

Before we look at the various types of diffuser on the market, though, how about essential oils themselves?

What Are Essential Oils?

Essential oils are extracts taken from natural sources like stems, leaves, flowers, bark, seeds or even whole plants.

These essential oils can be used to increase your well-being, treat illnesses and they can even supplement other therapeutic processes. When searching for the best essential oil diffusers, finding the best essential oil is just as important.

Essential oils work like a miraculous alternative medicine to treat skin diseases, nerve problems and other conditions resulting from a reaction to stress.

To use essential oils, it is best to inhale them in the form of mist. For this purpose, there are certain devices available used to create that mist by diffusing essential oils into the air. These tools are known as essential oil diffusers and they are available in different types depending upon the way they produce fumes.

Benefits Of Essential Oil Diffusers

Essential oils provide you with a variety of different and attractive scents. They form the backbone of aromatherapy and can give you some highly desirable psychiatric benefits as well. Essential oils can:

Moreover, there are a variety of other extraordinary health benefits… These oils can:

  • Loosen Nasal & Sinus Congestion
  • Moisten Dry Skin
  • Enhance Digestion

Made entirely from all natural plants, essential oils do not have the same make-up as regular oils.

There are no fatty acids like those seen in traditional oils.

Some essential oils are more expensive due to the amount of plant materials that are required. Mixtures can have very high concentrations. As beneficial as this can be, it can give also cause some allergenic adverse effects if applied directly to your skin. We recommend that you consult with your primary health provider first.

Some oils should not be used around pregnant women, young children, older people or pets.

Differences Between Humidifiers and Diffusers

Essential oil diffusers and humidifiers might seem as though they are the same but they are not.

A humidifier functions by dispersing moisture to either a particular area or the entire home.

A diffuser releases essential oils rather than moisture to a specific space.

Essential Oil Diffuser Advantages

  • Works to increase your mood
  • Filters and purifies air in the room
  • Decreases bacteria and fungi that can cause harmful health conditions
  • Helps you relax your body and mind

Humidifier Advantages

  • Eliminates dry air and adds moisture
  • Relieves congested nose, sore throat, cough and dry skin
  • Helps reduce snoring symptoms
  • Induced moisture prevents wood furniture from cracking

An essential oil diffuser can dual-function as both a diffuser and a humidifier. This makes it the ideal choice. You can, of course, buy these two separately but we strongly suggest making a single purchase. Having the ability to switch between the two operations is a luxury and saves you money into the bargain.

Features Of Essential Oil Diffusers

Essential oil diffusers have a wide range of different features. As with any product, these vary from model to model and according to the manufacturer.

Overall, they are very simple machines and are easy to operate. They come with additional user-friendly functionality to help with your overall experience.

Here are some standard features you will find with almost any essential oil diffuser…

Ultrasonic Essential Oil Diffusers

These devices use ultrasonic energy to diffuse essential oil. These electronic waves cause the oils to evaporate like a mist into the air. Ultrasonic models provide an excellent range of effects for people using aromatherapy. They may, though, lower the health benefits of essential oils by breaking them down while diffusing.

Evaporative Essential Oil Diffusers

These diffusers use absorbent pads on which essential oils rest. The oil is then evaporated into the air due to the heating. They are best for diffusing oils when you only need to have a good source of light fragrance in your room. The fumes produced may only be useful to make your room fragrant and may not have the specific health benefits you are looking for.

Nebulizer Essential Oil Diffusers

Nebulizer diffusers are rated the most useful diffusing devices for essential oils. They transform microdroplets of oil into undisturbed essential oil mist. These droplets last longer than other aromas produced by ultrasonic or heat-based diffusers. Enjoy maximum health benefits over long-lasting sessions.

Heat Essential Oil Diffusers

These diffusers heat the oil being placed in it and the vapors produced are spread around the area. They provide sufficient fragrance to the room but still affect the chemical composition and health benefits thanks to the heat. However, it is good to use this type if you only really need a tranquil environment with a nice aroma wafting around you.

Reed Essential Oil Diffusers

Reed diffusers, as the name indicates, have reeds to produce fumes in the air. The reeds are placed into the oil that is in the device and then flows to the top of the reed to be released. This process is a bit slow and may not be able to kick out aromas quickly around the room.

Candle Essential Oil Diffusers

Candle oil diffusers are stylish and often used as a decorative aroma device in rooms and spas to create a soothing environment. The oil is placed under the candle, and the candle slowly burns to release the oil into the air. The aroma produced is limited and they may unable to diffuse the fragrance over a large area.


All essential oil diffusers come in various models and shapes. Each one comes equipped with a combination of the above features. Look for what works best for you.

If you are looking for maximum bang for your buck with an eye on the health benefits as well as the pleasant smell, think seriously about investing in a nebulizer essential oil diffuser.

Our experience overall with this particular diffuser was a pleasing one. This is considered to be a “3rd Generation” Essential Oil Diffuser. Which means that its functions operate on a larger and more efficient scale.

4. URPOWER 2nd Version | Aroma Essential Oil Diffuser | Cool Mist Aromatherapy & Humidifier

URPOWER 2nd Version | Aroma Essential Oil Diffuser | Cool Mist Aromatherapy & Humidifier

Not to be confused with the Urpower 3rd version reviewed earlier, this is the version just before it. The Urpower 2nd version may be a later generation, but it is a highly valuable and affordable option. This Essential Oil Diffuser brings you features similar to others you have read about so far.

Essential Oils are not included with this Diffuser, but it can take a broad range of oils.

Easy to set-up and to operate making it an ideal choice for someone who wants to try out an Essential Oil Diffuser for the first time.

However, make no mistake, though this device may seem like a simple and possibly “cheap” option—it can provide you with what you are after. This diffuser can fill your room with sensual and pleasing scents as you relax into a peaceful slumber.

We were pleased with the results that we were given from an “older” version such as this. In reality, Urpower did not have much to improve upon with their 3rd version.

When we purchased this diffuser, we were told that it lasted longer than a majority of other products. Excited to see if this held true we used it as soon as it came in the mail that afternoon. We were displeased to find that it only lasted an hour. Confused I looked over our set up and the directions only to find that we did not put enough oil in it!

In fact, I missed the required mark by a long shot. After applying the right amount of oil, it ran for us throughout the entire evening. Without a sound or disturbance. So we would suggest that you implement the proper amount of oil to your diffuser before you use it.

The Urpower 2nd version may be a generation behind their 3rd version we went over earlier. However, it still can provide you with an adequate amount of Essential Oil vapor.
