Best Diffuser Reviews – Top 8 Picks
The Asakuki is next on our list in our search for the best oil diffuser in the UK. It has a short circular column design and is available in white or a light wood finish.
The Asakuki essential oil diffuser features LED lights in seven colours that can be adjusted to be bright or dim, an automatic shutoff function, four timer options, and a high or low mist mode. Unlike the other diffusers for oils on our list, Asakuki offers an upgraded model that has Wi-Fi capabilities that sync to an app on your phone. The app allows you to access all of the functions and even allows you to connect it to Alexa.
This is one of the best essential oil diffusers on our list for a large room in your home because of its large capacity. The tank can hold 500 ml of water and lasts up to 16 hours in low mist mode.
However, this aroma diffuser does not have an intermittent mist mode, nor a locking lid, and can not be battery operated.
- 7 colours of LED lights
- Good for a large room
- 1-year warranty
- Upgraded Wi-Fi option
- Up to 16 hours of continuous spray
- Lid does not lock
- Not portable

The Bobolyn diffuser is the best home diffuser if you are looking for something artistic. It has a compact design that comes in six different artistic options featuring animals and plant life cut out of the metal encasement.
The Bobolyn essential oil diffuser features an auto shut off function, seven colours of LED lights that are soft enough to serve as a mood light, as well as a constant and intermittent mist mode. We especially like this aroma diffuser because of its portable and rechargeable design.
Bobolyn’s tank only holds 100 ml of water but it has a powerful mist and runs quietly for up to four hours continuously.
Unfortunately, the Bobolyn does heat up as it is used which could be an inconvenience for some, it is not good in a home with large rooms, and its compact size requires regular cleaning to prevent clogging.
- Tiny but effective
- 6 artistic designs
- Durable metal materials
- 7 light colours
- Portable and rechargeable
- Requires regular cleaning
- Not suited for a large room
- Uses heat to diffuse oils
The Asakuki 700ml has a unique square-shaped body with contemporary wood grain accents on the base and lid. This makes a great choice if you are looking for a diffuser with an extra-large tank capacity and a high mist output with added humidity.
This Asakuki diffuser features a stronger vibration frequency that enables more mist with a denser consistency. As a bonus, it also produces a decent amount of humidity.
The extra-large 700ml tank can operate for up to 20 hours when on the low mist output mode. It also features an adjustable timer function, an automatic shutoff function to protect the motor and adjustable light brightness. We also love that the lid on this diffuser is easy to remove and easy to clean as well.
Unfortunately, this diffuser beeps every time you push a button which can be disruptive in some situations. You also have to cycle through every colour to reach the standard white light colour.
- Extra-large 700ml tank capacity
- Square shape with wood grain accents
- Humidifier function
- Timer and auto-shutoff
- Up to 20 hours of running time
- Beeps with every button push, which may be disruptive

The Tisserand Aroma Spa Diffuser is our favourite ultrasonic choice. It has a compact, cylindrical design with a slightly tapered flat top. It is only available in white with a large light-up top portion.
We really like the Tisserand oil diffuser because of its high-quality compact design. It features continuous and intermittent mist modes and an auto shut off function. It also has a soft light that changes between different, faint colours which can be set to steady or can be turned off completely while you sleep.
The Tisserand has a 100 ml tank capacity. On continuous mode, it will run for up to five hours and for as many as nine hours on the intermittent mist setting. No matter which setting you choose, this oil diffuser remains quiet and should not disrupt even the lightest sleeper.
Unfortunately, the compact size and smaller size of the Tisserand means it is not ideal for larger rooms and, additionally, it does not come with a warranty. It also requires a wall socket for usage so it is not portable. Lastly, this oil diffuser does not have a timer function but this may not be an issue for some.

This oil diffuser has a compact design featuring a 150 ml water tank capacity that lasts up to six hours on continuous spray mode. InnoGear even backs its products with a one year warranty.

A Buyer’s Guide to the Best Oil Diffusers
You have reached the end of our best aroma diffuser in the UK list. Now it’s time to examine what traits you should look for in the best scent diffuser so you can be sure the option you choose caters to your specific needs.
Benefits of an Oil Diffuser
The benefits of using an oil diffuser are many. First, the fragrance it emits can create a soothing and relaxing environment in the room it’s placed. This makes it extra useful in your bedroom where relaxing scents, like lavender, have even been known to improve your overall sleep quality.
Second, in the same way, oil diffusers can be relaxing, they can also be invigorating or increase focus when it comes to stronger, brighter fragrances like peppermint.
Third, an oil diffuser adds a small amount of humidity to your environment which can be nice in arid climates or during the warmer months of the year.
Types of Oil Diffusers
If you are wondering what type of essential oil diffuser is best, there are three main types you should be aware of when it comes to performance.
Ultrasonic diffusers use water and a chamber to build up pressure before emitting a fine, scented mist into the air. Ultrasonic oil diffusers are the most common because they are simple to use, often have advanced settings, add humidity to the air, and usually include a soft light as an added bonus.
In an evaporative diffuser, essential oil is put on a pad or other absorbing material and a fan is used to spread the oil scent around the room.
A nebulizing diffuser disperses essential oil rapidly without changing its chemical composition. They do not require heat or water to function and are also used for some types of medication. If you are asking, what is the best smelling diffuser? This might be the best type for you but really it depends on personal preference.
What to Look For in a Diffuser
What are the best room diffusers? It depends on the size of the room. If you want to use your diffuser in a large space you will want to look for one with a larger water capacity, something that holds about 500 ml of water. For a medium-sized room, a 300 ml capacity is usually sufficient. Anything with a capacity lower than 300 ml is best used in a small room.
The settings on an oil diffuser have a wide range. Some have only one spray setting while others have a light or strong mist mode and an intermittent or constant spray option. Another common setting includes timer functions that can be programmed in varying increments of time. The best aromatherapy diffuser for you will depend on how advanced you want the settings to be.
Whether or not you prefer your oil diffuser to have a light should also be a priority. Some prefer a diffuser that has no light at all for use in their bedroom while others enjoy a soft light to add to the ambience of a room. In addition, some diffusers have intricate lights that change colour. What type would you prefer?
How an oil diffuser is powered is also important. All of the products on our list are compatible with UK wall outlet power sources but some have the option to be battery operated or have a rechargeable power plug resulting in easy portability.
Now that you have a better understanding of what traits to look for in the best diffuser for the UK, let’s quickly review our Editor’s Choice – the Asakuki Premium 500ml essential oil diffuser, before you make your final decision.
Thanks to its 5-in-1 design, it not only provides you with the option of aromatherapy but is also able to purify and humidify the air of your home. We also liked that its large 500ml capacity lasts for up to 16 hours on the low mist mode and that it is made from BPA-free PP materials. With its seven LED light options, you can find lighting to suit your mood, and you can also use it without any light.
We know that was a lot of information to take in all at once but we are confident that you are now better equipped to pick the best oil diffuser in the UK that will suit your personal needs.
