How and Why to Use an Ultrasonic Oil Diffuser

Written by Sabrina Wilson and updated on December 8, 2016

People have been using essential oils diffusers for years. While some people use them to help with various health conditions, others tend to use them simply because they like the smell. Whatever your reason for using one, diffusers are a quick and easy way to provide yourself with hours of aromatherapy.

What is an Essential Oil Diffuser?

In a nutshell, an essential oil diffuser is a device that’s used to transform essential oils into vapor and disperse it into the air. One single oil may be used or a combination of oils may be used together for multiple benefits. 

Different Types of Essential Oil Diffusers

There are four main types of essential oil diffusers on the market today, all of which have their advantages and disadvantages. They are:

Nebulizing diffusers

 This type of diffuser uses no heat or water. It simply uses pressurized air to expel the essential oils out into the atmosphere. These diffusers are often considered to be the best as they can distribute the oil perfectly in a fine mist. That being said, they’re also the most expensive.

Ultrasonic diffusers

These diffusers are similar to the nebulizing type on that they too create a fine mist of essential oil. However, the way in which they work is different. Instead of using pressurized air to break up the molecules, these diffusers use ultrasonic vibrations in which to do the same job.

You get a great humidifying effect with these diffusers, which is great during the winter. The only real downside to using an ultrasonic diffuser is that you can’t use any citrus oils in them as there’s a high risk of erosion.   

Evaporative diffusers

Just as the name suggests, these diffusers work by using a small fan in which to evaporate the essential oil, releasing it into the air as a vapor. The main disadvantage to using evaporative diffusers is that they don’t disperse the oil evenly. The heavier components tend to sit at the bottom of the tank meaning you don’t get the full effect of the oil. The upside is these are usually the cheapest type of essential oil diffuser to buy.

Heat diffusers

These work in a similar way to evaporative diffusers, but instead of using a fan to disperse the essential oil, they use heat. They too are pretty inexpensive to buy and are really quiet. The main disadvantage with heat diffusers us that they are more of a fire risk. 

Reasons to Use an Essential Oil Diffuser

There are many reasons as to why people choose to use essential oil diffusers. Here are some of the most common reasons:

  • Pain relief. For years people have been applying essential oils directly to their bodies to help with pain relief. This has proved to be particularly useful in easing pain from sore joints, tense muscles, and headaches. Using a diffuser with certain essential oils such as lavender, ginger, or rosemary can help to enhance the effect.
