What A Diffuser Is And How It Works

So what is an essential oil diffuser? A natural oil diffuser (often referred to as an aromatherapy diffuser, aroma diffuser or an essential oil diffuser) is a device that is used to disperse essential oils into a room or area. Through this process, the aroma of the essential oils fills the room, providing a beautiful fragrance and in some cases, therapeutic benefits.

Usually people place a scented oil diffuser in their living areas, bedrooms, offices and you can even get an essential oil car diffuser.

electric oil diffuser

Whilst there are a variety of diffuser types and ways in which the essential oils are dispersed into the air, in general the user simply places their favourite essential oil into the diffuser and the device works its magic to disperse the essential oils.

Essential Oil Diffuser Benefits

Whilst there is no doubt that the combination of your essential oils and diffuser will have your room smelling absolutely divine, there are also a range of therapeutic aromatherapy diffuser benefits that the best essential oil diffuser 2021 Australia will bring as well:

  • Encourages you to relax and bring calmness;
  • Reduces stress levels and helps to relieve anxiety;
  • Clears the lungs and aids in respiratory colds;
  • Helps improve sleep quality;
  • Reduce the build up of bacteria and mould in the home;
  • Discourages mosquitoes; and
  • Much safer than burning candles.

Finding The Best Diffuser Australia For You


If you’re looking for the best aromatherapy diffuser Australia has, know that there are several different types available. From an electric diffuser Australia to ultrasonic diffuser reviews, I’ll go into the different types of diffuser available below.

Ultrasonic Essential Oil Diffusers. An ultrasonic essential oil diffuser (also often referred to as an aroma or fragrance diffuser), uses ultrasonic vibrations to spread essential oils into the air as a fine mist.

A benefit of an ultrasonic essential oil diffuser is that it doesn’t use heat, making it the best diffuser for home use, particularly when small children are around.

While they only need 1 or 2 drops of essential oil to create a subtle aroma, they don’t tend to be as good as the other types of diffusers.

Nebulizing Essential Oil Diffusers. A nebulizing essential oil diffuser (also referred to as an oil atomising diffuser) breaks essential oils into separate molecules before dispersing into the room, and nebulizing diffuser Australia options are a great way to spread the aromas of essential oils without heating them.

It is said that by having the oils broken into smaller molecules it is easier for the lungs to absorb and therefore achieving greater therapeutic benefits as opposed to what other diffusers provide. The downside of an essential oil nebulizer is that they can be more difficult to clean.

Reed Diffusers. An essential oil reed diffuser is perfect if you’re after a cheap essential oil diffuser as you can even make them yourself. This type of diffuser is simply reeds placed into the essential oil. The oils absorb up through the reeds and the scent is dispersed into the air.

Heat Diffusers. The above types are all cold air diffuser Australia options, whereas a heat diffuser quite simply heats the oils until they evaporate into the air. Heat diffusers come in a range of types including electric essential oil diffuser, candle, heat and lamp ring. Heat diffusers are usually inexpensive, however the process of heating the oils does somewhat reduce their overall therapeutic benefit.

Evaporative Diffusers. An evaporative diffuser uses a fan to generate wind so that the oil evaporates into the air. The best air diffuser Australia is effective in spreading the oil around the room without needing to heat it. In a cold air diffuser, the oil is held in an absorbent pad or wick.


Before purchasing a diffuser, consider what you will use it for and where you want to place it. Whilst you want a good diffuser that is fully functional, you don’t want it too bulky as you’ll want to ensure it can easily sit out of the way. The best room diffusers Australia are small enough to be able to easily move around.

A nice small essential oil diffuser also ensures it’s easy to move from room to room, and you can even take it away on holidays with you. The best oil diffusers will be compact and easy. If you’re looking for a diffuser for large room Australia option, then a larger diffuser might work better.

Water Capacity

For diffusers that use water to operate, you’ll need to give consideration to the diffuser water capacity. Obviously the larger the water capacity, the longer you can use your diffuser without having to fill it up.

However, you’ll need to weigh this up against the size of the diffuser, as a large water capacity also means a large essential oil diffuser.

Other Features

Here are some other features to keep an eye on when comparing the best diffusers on the market Australia:

Functionality – Like any device these days, the best room diffusers come with a range of different functions such as ioniser, humidifier, night lamp, intermittent mist, auto-off feature etc.

Be sure to know the main reason you’re purchasing the best aroma diffuser so you purchase one that you’ll be happy with. For example, if you want a room diffuser that doubles as an essential oil diffuser humidifier to aid with sleep for a child, you may want to consider a bedroom diffuser with a built in lamp as well as an auto-off feature.

Noise Level – You really want your fragrance oil diffuser just to blend into the background, so it’s vital that your diffuser is quiet as possible. So be sure to check the noise output of the diffuser.

Around 23 decibels is ideal, but also check other customer reviews to see what they say with regards to the noise level.

Design – Best essential oil diffuser 2021 models come in a range of sizes, shapes and colours, from the basic to the elaborate.
