Essential oils offer a wealth of benefits, from making a room smell crisp and clean to easing stress, tension and promoting relaxation. If you want to experience the full benefits of essential oils, you’re going to want to have a diffuser. Whether you are interested in filling your home with or office with a fresh scent or you want to enjoy the therapeutic benefits of essential oils, a diffuser is an absolute must! However, there are tons of oil diffusers on the market, so finding the best one to meet your specific needs can be a bit daunting. To help make the process easier for you, we have put together this handy buyer’s guide to help you find the best oil diffuser for your specific needs.

Types of Oil Diffusers

There are four main types of oil diffusers on the market, and each type offers different benefits:

Nebulizing Diffusers

These diffusers are comprised of a jet of air, which blows across the top of a small tube, creating a vacuum that pulls the essential oil from the bottom of the tube up to the top of the tube. The air flow that blows across the surface of the tube blows the oil away, turning it into a fine spray or mist. A nebulizer diffuser saturates the air with the essential oil quickly and because it has a constant supply of air, it puts out a large amount of oil. It also puts the oil into the air in the form of droplets, which is why a nebulizer diffuser is often thought to be the best type of diffuser for reaping maximum therapeutic benefits of essential oils. On the downside, these diffusers tend to make the most noise.

Ultrasonic or Humidifying Diffusers

Similar to nebuilizing diffusers, ultrasonic diffusers also create a fine mist; however, the method that is used to create this mist is very different. This type of diffuser uses electronic frequencies, which allow a small disk that under the surface of the oil at a very rapid rate. The ultrasonic vibrations break down the essential oil into small microparticles, which are then dispensed into the air in a fine mist. These diffusers not only carry the essential oil into the air, but they also humidify the air; however, on the downside, the mist that these diffusers put out only contains a small fraction of actual essential oil.

Evaporative Diffusers

The process of how an evaporative diffuser works is really quite simple; they contain a fan, which blows air from the room through a pad or filter that has been saturated with essential oils. As the air blows through the fan and passes over the saturated pad or filter, the oils evaporate and are blown out of the diffuser and into the room. On the downside, the therapeutic properties of the essential oils are broken down somewhat when used in an evaporative diffuser; however, they do distribute the essence and scent of the oils while operating at a relatively quiet level.

Heat Diffusers

Similar to evaporative diffusers, heat diffusers allow the essential oils to evaporate quickly, but they use heat instead of air to diffuse the oils. The oil is placed on a tray, which is then heated with an electric element. They are ideal for use in smaller spaces, as they usually aren’t powerful enough to fill larger spaces. Also, make sure that you use a head diffuser that uses low levels of heat, as higher heat can actually alter the chemical constituents of the essential oils that they diffuse.

Oil Diffuser Considerations

Before purchasing a diffuser for your essential oils, there are certain factors that you are going to want to take into consideration to help you choose the best type for your specific needs. We think the following factors will allow you to make the best choice.

The Space

What room will you be using your diffuser in? The size of the room is an important factor to consider because you want to make sure that the oils are being spread through the entire space. The larger the room, the larger the diffuser you will need. Also, the room you will be using the diffuser in is also important when considering the noise level that the diffuser will make. If you plan on using it in a bedroom, you may want to opt for a quieter diffuser so that you don’t disturb your sleep.

The Therapeutic Benefits

As mentioned above, different diffusers put out different amounts of essential oil. If you want to reap the maximum therapeutic benefits of the oil, you should consider using a nebulizing diffuser; however, while these diffusers disperse the highest amount of the actual essential oil, they tend to be the loudest.

Your Oil Preference

The type of oils you plan on diffusing should also be considered before you choose a diffuser. The chemical makeup of the oil can actually impact the diffuser itself. For example, citrus essential oils can actually erode the components of an ultrasonic diffuser.

Ease of Use

When you are trying to enjoy the benefits that essential oils offer, the last thing you want to do is struggle with the setting up the diffuser. Make sure you choose one that is easy to set up and operate so that you don’t have to contend with a big production. Also, consider how easy it is to clean. Essential oils can be a bit tricky to clean, so look for a diffuser that makes the process of cleaning up easier for you.

The Price

Cost is another important factor that you should take into consideration before deciding which oil diffuser is right for you. Diffusers vary significantly in price, ranging from around $50 to upwards of $100 or more. Generally, the larger the diffuser and the more features if offers, the more expensive it will be.

Oil Diffuser Features

Essential oil diffusers can be very basic, or they can be more sophisticated and offer a lot of features. You may find that some of these features will greatly benefit you, while others you may have no use for. Understanding these features will help you choose the best type of oil diffuser for your needs.

A Timer

A timer can be a handy feature on an oil diffuser. Simply set up your diffuser, set the timer and it will operate during the times that you have selected, which means that you won’t have to worry about watching over it constantly, and you won’t have to remember to turn it on and off.

Automatic Shut Off

An automatic shut off is another handy feature. While you do have to remember to turn the diffuser on, this feature will automatically shut it off when it detects that the oils have run dry, or if it has been running for a long period of time. An automatic shut off can save you from mishaps and provide you with greater peace of mind.

LED Lights

Some oil diffusers feature LED lights, which can enhance your enjoyment. These lights can add to the calming effect the oils that are being diffused offer; plus, they are a great feature if you want to dim the lights and have some low light. In a bedroom, for example, the LED light source could serve as a nightlight. Some diffusers that feature LED lights also offer different color options, the lights can be dimmed, they can be set to rotate from color to color, or they can be set to turn off after a certain amount of time.
