What Are Essential Oil Diffusers and How to Use Them

Essential oil diffusers, also known as aromatherapy diffusers, are a common device that most people use to utilize the essential oils they love. These devices help in maximizing the benefits that you can get from essential oils which are the natural way to detoxify, calm, or stimulate one’s senses.

How Do Essential Oil Diffusers Work?

Generally, most diffusers work by breaking the essential oil down into small particles. The diffuser will disperse these tiny particles into the environment. As a result, those who are inside the room with the diffuser will inhale these small particles.

For this reason, you have to pick a high-quality and natural essential oil to use with your diffuser. You do not want chemicals and other artificial products traveling to your lungs.

Benefits Of Using Them

Here is a quick list of benefits that one can get from using an essential oil diffuser in conjunction with effective essential oils.

  • Purifies the air
  • Freshens the environment
  • Improves the immune system
  • Improves concentration
  • Calmness and relaxation
  • Peaceful feeling

Different Types of Diffusers

This is a brief overview of the most popular types of diffusers available right now. If you think you’re ready to buy a diffuser, make sure to read our article ranking the best essential oil diffusers right now.


The ultrasonic diffuser is the most conventional aromatherapy diffuser that most people use nowadays. Unlike the other diffusers, the ultrasonic uses electronic frequencies for dispersing the essential oil in the air by creating small vibrations.

This device makes use of water. Thanks to it, some people use it as a humidifier at the same time, especially during winter.


If your main goal is to maximize the therapeutic benefits of your essential oil, then the nebulizer is the best option for it. It has motors and a bottle or glass cylinder. It works by breaking the essential oils down into small molecules and disperses these particles which are more absorbable into the air. Thus, it increases the benefits of the essential oil.

Electric Fan

The electric fan diffuser works without heat. First, you have to put a few drops of essential oil to the water or a pad. The diffuser’s electric fan will blow air to the water or pad and diffuses the essential oil particles to the air.


If your primary goal of using an essential oil is only to make a room smell nice, the candle diffuser is a cheap option to use. However, do not expect any therapeutic benefits because the candle diffuser uses heat to disperse the smell into the air. Heat changes the properties of the oil.


This type of diffuser can be made from ceramic or terra cotta. You may use this kind of diffuser in a small room. Just a drop or two of essential oils will do.

It works by evaporating the oil and dispersing its small particles in the air.


The reed is a unique type of diffuser because it makes use of rattan sticks. These sticks serve as channels to allow the oil to travel and fill the room with the oils’ scent.

If you choose to use this type of diffuser, you have to be mindful of the oils that you are going to use with it. Remember that some oils will diffuse faster in a reed diffuser than the other kinds.

So, if you want a faster effect, use oils like grapefruit, lemon, bergamot, and other light oils with the reed diffuser.

Note: Never Use a Humidifier as an Essential Oil Diffuser

These two devices are different from each other. The primary purpose of a humidifier is to increase the humidity inside a room. You commonly use just plain water as the principal moisturizing agent for cleaning the air. Humidifiers are not for essential oils.

You might ruin your device if you use your humidifier as a diffuser.

How to Use Essential Oil Diffusers?

Since the ultrasonic diffuser is the most commonly used device, here is how you can use it.

  1. In a room, select an area that is open and has a solid surface like a tabletop. Make sure that it has a nearby outlet and is away from fan air or sunlight.
  2. Use clean water to fill the water container at room temperature. Make sure not to go beyond the fill line. You have to read the manual to learn how much water you need to add for a particular device.
  3. Add at least three drops of the essential oil to the water.
  4. Turn on the diffuser.

How to Clean Your Diffuser?

If you haven’t read our diffuser cleaning article, here’s a quick overview.

Note: Unplug the device before the cleaning process.

  1. Fill the device with clean water.
  2. Add approximately 10 drops of vinegar.
  3. Now, plug your device and turn it on.
  4. You may run the vinegar solution in the unit if you want to.
  5. After running the solution, unplug and pour the water-vinegar solution.
  6. Clean the device with a cotton swab.
  7. Rinse with warm water.
  8. Air dry.

What Should You You Keep in Mind if You Clean Your Device?

Take note as this is very important. Before cleaning your essential oil diffuser using the method suggested above, you must read your warranty conditions first.

Sometimes, using vinegar for cleaning the device voids its warranty. If that is the case, you should call the manufacturer and ask for the proper way of cleaning the equipment you have.
