Best Diffuser Reviews – Top 8 Picks

Asakuki Premium (Editor’s Choice)

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
  • No intermittent mist function

Bobolyn Metal Scenery (Best Design)

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

Asakuki 700ml 5-in-1 Ultrasonic Aromatherapy (Long Running Option)

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
  • It may be a bother to flick through the colour options
  • May not include essential oils in the package

Tisserand Aromatherapy (Ultrasonic Choice)

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.


  • High quality
  • Ultrasonic mist
  • Super quiet
  • Auto shut off and intermittent modes
  • 2018 Baby Shortlist Mama & Baby Award


  • Not for large rooms
  • Small tank capacity
  • No warranty

InnoGear Adjustable (Quiet Choice)

The InnoGear essential oil diffuser is our top choice for anyone seeking a super quiet choice. This aroma diffuser has a cylindrical base with a slanted top and is available in three colours: white, light wood finish, and dark wood finish.

Each colour option of InnoGear’s essential oil diffusers features a light but only the white has a glowing body design. The two wood finished options only have a small light on top and are more ornamental. Each oil diffuser has a constant or intermittent spray option and features an automatic shutoff for safety.

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.

If you’re considering this option, be aware that due to its compact size it is not good for a large room, it does not have the option to be battery operated, and there is no timer function.

  • 1-year warranty
  • Constant or intermittent mist
  • Compact design
  • Ornamental or glowing light design

The compact tank on this oil diffuser holds 120 ml of water that lasts for up to four hours. The handmade cover is made from durable, thick glass so you shouldn’t have to worry about its fragility.

The smaller mist opening on this particular essential oil diffuser makes cleaning regularly a necessity. Also, it only has one mist strength that cannot be set to intermittent and its smaller size means it is not ideal for a home with large rooms.

Hence, you can increase the scent or prolong the operation time based on your preference. It also has a whisper-quiet operation, so it should not disturb you while you sleep.

The Criacr diffuser features an LED light with seven different colours and two different brightness levels, allowing you to change the ambience of a room with a push of a button. It also has anti-slip rubber feet to prevent accidentally knocking it over and an automatic shutoff to protect the motor.

Be aware; the Criacr diffuser lacks a timer function. It will run until the water is lower than the tank and will automatically turn off. It also has a trickier lid to screw on and off. Plus, it could spray droplets of water, creating a mess if the tank is accidentally overfilled.

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?

Power Source​

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.
