Whether you want to add a soothing element to your office or home or you’re a fan of aromatherapy and searching for an air freshener, buying an essential oil diffuser can be the answer.

That said, a lot of people ask themselves questions “How to choose a diffuser” and “Which diffuser will be right for their space”, wondering if the one they pick will be able to handle the area and provide the full benefits that these devices can offer. Is it what you’re asking yourself too? Hopefully, after reading this article, you’ll get all the answers and picking the best essential oil diffuser won’t be a problem for you. 

Tips on Choosing an Oil Diffuser

Larger Capacity Doesn’t Mean More Power

Larger capacity doesn't mean more power

First things first bear in mind that a large diffuser doesn’t mean a powerful diffuser. What “large” usually means is the capacity of a water tank that a diffuser accommodates. Does a larger capacity allow it to cover bigger space? No, not at all. Unlike what some people mistakenly believe, larger size options only mean that an oil diffuser can run for a longer time before a refill is required, not that it will be able to handle larger open spaces. 

Two Is Better Than One

Next, it’s essential to understand that there is a certain limit to how far the mist can be spread around the room. So, if you have a living area that is bigger than 1,000 sq.ft., expecting one unit to provide a strong mist to cover the whole space would be just too optimistic. In cases like this, it would be much more reasonable to get not one but two diffusers and get two of the same things that feature the same strength, the same power, and the same water tank capacity. By doing this way, you’ll achieve bigger coverage and get confidence that the mist will reach the farthest corners of a room. 

Use High-Quality Oil

Naturally, in order to have a strong scent, it is important to use premium essential oils. Anything that is too cheap is usually diluted down with other ingredients that not only weaken the oil strength but can actually cause headaches and other unpleasant health conditions. 

Aside from this, it is important to use enough oil. If you add just a small amount of oil drops to your diffuser, the mist will be weak and you won’t feel it in a spacious room. The recommended ratio to go by for a room of average size is between 3-6 drops of oil per 100 ml; for a larger work or home space, this amount can be safely doubled. 

To give you an idea of how to estimate the needed amount of oil droplets, a 300m diffuser with a 150ml water tank capacity will need around 9-10 drops of oil. This means a 500ml essential oil diffuser will need at least 15-20 drops, and if you go over this amount you’ll get even a stronger effect. 

Decide on the Type of an Essential Oil Diffuser

Types of oil diffusers

Finally, do not forget that there are four major types of oil diffusers to choose from: 

  • Nebulizing;
  • Heat;
  • Evaporative;
  • Ultrasonic.

The distinguishing feature of nebulizing diffusers is that they diffuse only the essential oil and use no heat or water. For the same reason, however, they are also the most expensive option.

When it comes to heat diffusers, as you can guess from the name, they use heat elements to break down the oil and cause it to evaporate. Dissimilar to nebulizing diffusers, they use oil mixed with water, which makes them more economical.

As far as evaporative models go, those are featured with a fan that uses the moving air to circulate the particles of the essential oil and cause it to evaporate. The benefit of this diffuser is that it provides phased diffusion, releasing the lighter components first and heavier components last. The downside: they produce more noise than other types. 

Ultrasonic diffusers, in turn, are perhaps the most popular. They work with the help of electronic frequencies and water, and can act as both a diffuser and a humidifier. Thanks to this, they perfectly suit those people who live in a drier climate and need a multi-functional device to alleviate the respiratory ailments during allergy/cold seasons. Besides that, they produce almost no noise, use very little oil, and more often than not, can cover larger spaces. 

Below, we offer you to check one of the best essential oil diffusers that use ultrasonic technology. To learn more about the full benefits of using essential oils, make sure to read this post.
