How To Choose The Best Essential Oil Diffuser

Using essential oils can be great for your mental and physical health. When oils are diffused in the air, they can offer stronger benefits than they would normally. While some people put their oils into a humidifier, it’s better to use the best essential oil diffuser. I want to help you learn how to find a good diffuser to meet your needs.

Types Of Essential Oil Diffusers

There are four main types of diffusers that you will have to choose between. Each has a different way of diffusing the essential oils. Here are some of the main characteristics of the four diffusers:

  • Nebulizer

A nebulizer diffuser works in the same way as a perfume sprayer by doing something called atomizing. You will hook the diffuser up to the bottle of oils directly, and a jet of air will blow over the top to draw out the oils. This breaks up the whole oil into tiny droplets and sprays it into the air. No water is mixed in with the oils as they’re spraying out, making the concentration higher.

Nebulizers spray oils very quickly into the air, so they’re good for making a high concentration of oil as fast as possible. However, they also use a lot of oil compared to others, so you might end up having to buy more oils when you use a nebulizer.

  • Ultrasonic

Diffusers that use ultrasonic technology are similar to humidifiers, except that they give off a cool mist instead of hot steam. You pour a few drops of oil into the reservoir and mix it with water. Then, a rapidly vibrating plate will break up the oils and water into microparticles.

These particles will disperse into the air and create a water vapor with a small concentration of essential oils. There won’t be as much in the air as there would be from a nebulizer, but it is still a good concentration to get some of the benefits from the oils. Ultrasonic diffusers work well in the winter, since the humidifying benefits keep your airways moist in the dry weather.

  • Heat

While this is usually considered the worst form of diffuser for aromatherapy benefits, it’s perfect for getting the scent into the air. Some use high heat to get the oils into the air quickly, but the best heat diffusers use low, consistent heat to evaporate oils and water into the air.

One of the benefits of a heat diffuser is that this method of use is completely silent. It also works very quickly to get the scent of the oil out into a room. However, because the heat breaks the oils into different components before dispersing them into the air, you won’t get all the benefits from each oil.

  • Evaporative

Instead of using heat to evaporate the oils, an evaporative diffuser sends air through a tube and into sponge or filter with essential oils. This breaks up the oils into tiny particles and disperses them into the air. No water is needed, so the setup is very simple.

Similar to heat diffusers, these diffusers don’t provide the best aromatherapy benefits. The reason for this is the oil particles are broken into smaller pieces and diffused unevenly. For the first 30 minutes or so of diffusion, the small particles will be diffused into the air. It takes longer for the larger particles to be diffused, so you won’t get the full benefits of whole oil diffusion. Also, these machines can be a bit louder than some other types, since they must use constant air flow to work.

Benefits Of A Good Diffuser For Essential Oils

  • Aromatherapy

Essential oils are known to have a lot of therapeutic benefits when they are diffused in the air. Aromatherapy is practiced around the world for mental and physical health. Its benefits are numerous, and you may find that a condition you’ve been dealing with can be treated with the right aromatherapy routine.

  • Pleasant Smells

Essential oils put a fantastic scent into the air. When you diffuse the oils, you’ll be spreading the scent of the specific oil as an air freshener around the space the diffuser is in. What a great way to make your house feel welcoming to guests, or to create the right mood on a dreary day!

  • Concentrated Benefits Of The Oil

It’s hard to list all of the benefits of a diffuser, since that partially depends on the type of essential oils you are using. Each one has its own benefits, and they can help with anything from stress to sleep or headaches. Choose whichever oil suits you best, and a diffuser will help you to get the best out of it for your improved health.

How To Choose The Best Essential Oil Diffuser

There isn’t much to look for in a diffuser, but here are the main characteristics to choose from:

  • Type Of Diffuser

I went into detail about the types above, but the basic types you’ll find are the nebulizers, ultrasonic, heat, and evaporative diffusers. The most common by far is the ultrasonic, since it’s a good mix of aromatherapy and humidification at a reasonable price. Nebulizers are fantastic for aromatherapy, but they’re usually significantly higher cost.

Heat and evaporative diffusers are not common, because they don’t offer the aromatherapy benefits that the other two have

  • Automatic Shutoff Functions

It’s convenient to have a machine that will shut off after a certain period of use, so that it doesn’t get ruined or waste oil. Automatic shutoff is great for using the diffuser at night for sleep as well, because it will turn off after helping you fall asleep.

  • Capacity

When you’re dealing with any type of diffuser, you’ll want to know how much oil or water it can hold at once. Ultrasonic diffusers mix the oils and water together, so the capacity is especially useful knowledge on these devices.

  • LED Lights

Many diffusers now come with LED lights that will turn on to form a pleasant glow around the diffuser. Some will change colors to create a relaxing mood. Combined with aromatherapy, the lights create a nice mood for you to fully enjoy your essential oils.
