The Best Essential Oil Diffusers To Buy Online In Australia
We’ve rounded up our picks for the best essential oil diffusers to help create a pleasant, therapeutic smell in your room.
Best Overall Diffuser
Asakuki 500ml Essential Oil Diffuser
- Can cover up to 32 square metres
- Comes with an auto shut-off switch
- Seven different LED light colours
- The design and size of the device make it very bulky
This diffuser comes with a 500 ml water reservoir, which is quite sizeable compared to most standard diffusers. The problem is that the large water capacity also makes this device a lot bulkier than the other diffusers as well, which means that you’ll have a bit more of an issue finding a place for it.
It comes with several different light modes, a safety switch that automatically turns the diffuser off when there’s no more water or when it starts to overheat, and a wooden base for a bit more of an aesthetically pleasing appearance.
The buttons at the bottom allow you to easily select any of the one, two, or three-hour run timers. You can also set it to the weak mist setting that will allow you to use it continuously for 16 hours.
Best Ultrasonic Diffuser
Vitruvi Stone Diffuser
- Very quiet
- Can cover an area of around 46 square metres
- The design is minimalistic and aesthetic
- Expensive compared to other diffusers
- Lid needs to be cleaned frequently
This diffuser breaks down the essential oil by using ultrasonic vibrations to create a fine mist that can be spread throughout the room. The only drawback to this sort of diffusion is that some of the oils are a bit too thick to be completely broken down into a mist, so you might be left with a bit of residue on the bottom of the reservoir when the water is gone.
This diffuser can either be set to constantly run for three hours, or you can turn on the timer that will set it to run for 30 seconds and then rest for 30 seconds, which will allow you to use it for up to seven hours. The water reservoir under the lid holds 90 ml of liquid, and there’s a clear fill line that shows you how much water you need for the diffuser to run for a maximum of three hours (as well as the intermittent seven hours).
Best Nebulising Diffusers
Raindrop 2.0 Nebulizing Essential Oil Diffuser
- Simple to use
- Has an effective radius of 74 square metres
- You can't select one colour for the light, it has to be either off or rotating through colours
The Raindrop is a very simple but aesthetically pleasing essential oil diffuser. As the name suggests, this device is shaped like a raindrop and has a wooden base with rubber anti-slip feet. Moreover, it doesn’t require any water in order to spread the essential oil’s fragrance.
The nebulizing nature of the diffuser allows the aroma to disperse naturally throughout the air without being diluted with water like other models. It can either work continuously until it runs out of oil or with a two-hour timer. Setting the timer will have it work on two-minute diffusion and one-minute rest intervals, which will still spread a pleasant aroma while also being a bit more economical with the oil usage.
You also get rotating LED lights that can work as a simple night-light, which is a perfect use for this device since you can enjoy a nice relaxing aroma as you drift off to sleep, undisturbed by the very silent motor that it runs on.
dōTERRA Lumo Diffuser
- Covers up to 50 square metres
- Takes up minimal space
- Good looking design thanks to the wooden base
- The plastic components will need to be cleaned frequently
The most striking thing that sets this diffuser apart from the rest is probably the maple wood base, giving it a more natural feel. The top also lights up in a variety of colours, which means that this is a great item to set a romantic or relaxing mood if you have the lights in the room off and a nice aroma is wafting through the air.
The lights can be turned on and off, which means that you can either use the diffuser as a nightlight or turn them off entirely if they’re bothering your eyes.
This device will last between two and five hours if you set it to omit a scent of your choice constantly. You could also set it to work in five-minute intervals for up to ten hours if you’re looking for a more spaced-out aroma dispersal throughout the day.
How To Choose The Right Diffuser
How Do Diffusers Work?
Diffusers use several different means in order to break down essential oils into small particles that can be converted into mist and then spread throughout the room where the diffuser is located. Certain diffusers accomplish this by using ultrasonic sounds, while others use heat, but the exact method will depend on the sort of model that you pick.
These devices spread a pleasant aroma through the air, and certain essential oil scents are popularly claimed to be able to help you sleep better and provide other benefits to your health and your mood. Diffusers also don’t improve air quality like humidifiers or air purifiers do, but they’re also not as expensive as those devices.
Ultrasonic diffusers use vibrations to break down the oil molecules and turn them into mist, which has a semi-humidifying effect of adding a bit of moisture to the air due to the water that gets evaporated. The problem is that the water dilutes the smell from the oil, and the plastic lids are susceptible to corrosion, so they need to be cleaned constantly.
Evaporative diffusers use a fan in order to turn the oil into a gas, which usually means that they can cover a wider area than the other diffuser models. However, the fan also makes these diffusers the loudest models by a noticeable margin.
Heat or electric diffusers use a heating element in order to turn the oil into a gas. Heating up the oil has the effect of changing its chemical properties, which might result in it the aroma actually getting stronger as a result. Keep in mind that some oils will be diluted as well, which will make the aroma weaker.
Ultrasonic diffusers dilute the smell slightly but are the best choice if you want a constant slight scent to seep out during the entire day. Evaporative diffusers can cover the largest area, but they use a lot more power. Heat diffusers can either give you a strong or a slight aroma depending on the oil that you use, but they also burn up the oil very quickly.
