How We Picked The Best Oil Diffusers

We look at a wide range of criteria when ranking the best essential oil diffusers. We primarily look at the functionality when ranking these products but have also considered the aesthetics.

To put together this list, we searched Australian retailers, marketplaces, and independent brands to get a comprehensive view of what’s available. We then removed the obviously low-quality products until we had a shortlist of 20 different consumers.

We then compared the functionality of each unit against similar diffusers and removed the loser. This resulted in a list of 12 diffusers. We then cut this list in half based on aesthetics. The result is the list of the best essential oil diffusers you see below, which we believe truly represent the best Australia has to offer.

What to Consider When Buying an Essential Oil Diffuser

There are different types of diffusers that use a variety of different methods to diffuse. Each has strengths and weaknesses but the end results are similar.


Ultrasonic vibrations are created by sending out electronic frequencies, which agitate the oil and disperse mists of oil, or water through the air.


The nebulizer is the simplest, quickest way to release essential oils into your system. They do not use heat or water – just air and a few drops of oil! The stronger concentration means they’re great for when you need quick relief from congestion.


Evaporative diffusers use a fan to turn plan essential oils into vapor before distributing them throughout the room. The process can be cheaper than other similar devices, but it won’t work well in smaller rooms where there’s no airflow for diffusion purposes.


A heat diffuser is an essential oil holder that uses direct heat to activate and disperse essential oils. However, it’s important for users of these products to know the potential harm caused by too warm liquid temperatures as they can damage some scents and oils beyond repair!
