Best Diffuser Reviews – Top 10 Picks

VicTsing 300ml (Editor’s Choice)

The VicTsing ultrasonic oil diffuser is one of our top choices for the best oil diffuser in the UK. Its sleek onion-shaped design is available in two stylish wood grain finishes.

When it comes to essential oil diffusers, this one has quite a few advanced setting options. The VicTsing electric diffuser has 15 light colour changing modes with seven different colours to choose from! You can also decide between a steady or sporadic mist option and four timer settings. It also features an automatic shutoff when the tank empties for extra safety.

VicTsing’s aroma diffuser comes with a two-year warranty backing its durability. It has a 300ml water tank and can run continuously on low for up to 10 hours.

While VicTsing boasts that its ultrasonic diffuser is whisper-quiet, consumer reviews indicate otherwise. Also, it is not portable and the lid does not securely fasten. Instead, it simply rests on top making it less secure.


  • 2 natural wood grain finishes
  • 4 timer settings with auto-shutoff
  • Lasts up to 10 hours
  • 2-year warranty
  • 15 light modes


  • Not silent
  • Lid doesn’t fasten
  • Not portable

Anjou Set (Luxury Choice)

The Anjou essential oils diffuser sports an onion-shaped design with a cloudy opaque top and a light wood-finish base.

We chose the Anjou as one of the best essential oil diffusers because it comes with 12 different essential oils to either get your collection started or give it a major boost. We also like it because of its advanced setting options which include seven colours of LED lights that can be on high or low, including four timer settings, as well as an automatic shutoff function.

The water tank on the Anjou essential oil diffuser has a 300 ml capacity and can run continuously for six to eight hours.

Like many high-quality products, the Anjou should provide you with some long-lasting durability but it does not come with a warranty. This essential oil diffuser does require regular cleaning due to the smaller mist opening but our only other complaint is that it doesn’t feature an intermittent mist spray mode.


  • Elegant design
  • Comes with 12 essential oils
  • 7 colours of LED lights
  • 4 timer options
  • Strong mist


  • No warranty
  • No sporadic mist
  • Requires regular cleaning

VicTsing 150ml (Best Value)

VicTsing makes our list again as the best value choice with their smaller, half-size essential oil diffuser. This diffuser has an aesthetically pleasing stand up cylindrical design with a curved top and comes in white or with a wood-finished base.

This version of the VicTsing oil diffusers has a three-hour timer setting, an automatic shutoff, and eight LED light colour settings that can cycle through or can remain constant depending on your preference. VicTsing also gave this model a Sleep Mode option which turns the light off and reduces the mist output which minimizes the sound and allows it to run for longer.

This aroma diffuser has a smaller 150 ml water tank capacity which enables it to run for up to nine continuous hours when set to Sleep Mode.

Due to the compact size of this VicTsing essential oil diffuser, it only has one timer setting and it is not suited for scenting larger spaces. Also, it does not come with a warranty.


  • Sleep mode
  • 8 colour LED lights
  • Compact design
  • Automatic shutoff
  • Whisper quiet


  • Only 1 timer setting
  • Not ideal for a large room
  • No warranty

Tisserand Aromatherapy (Best 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 (Best 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.


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


  • Insufficient for a large room
  • No timer
  • Not portable

Asakuki Premium

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

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

Bobolyn Glass Fireworks

Bobolyn features in our search for the best essential oil diffuser again with their unique diffuser which has lights that have been made to resemble a stationary fireworks display. It has a handmade vase-shaped glass cover.

This Bobolyn diffuser features an auto shut off when the tank empties, four timer setting modes, and seven colours which can cycle or stay fixed. The unique light pattern makes this oil diffuser a beautiful addition to any room

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 a 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.


  • Handmade glass cover
  • Fireworks light design
  • 4 timer options
  • 7 light colours
  • Vase-shaped design


  • Requires regular cleaning
  • Only one mist strength
  • Not suited for a large room or home

Aimason Ultrasonic

The Aimason also makes our best essential oil diffuser list. It has a wide cylindrical shape and a wood-finished base with a large light dome on top.

The Aimason essential oil diffuser features 7 colour changing or static light modes, includes an auto shut off function, and has an adjustable mist that can be set with a timer. Additionally, it has a high or low output mode to make your oils last longer.

The large 500 ml water tank lasts for up to 16 hours on this essential oil diffuser. Unlike the other diffusers on our list, the Aimason comes with a handy remote control for easier access.

On the down side, some consumers report the Aimason has an awkward way of opening and it being noisier than they expected. Also, it is not portable.


  • Remote control access
  • Adjustable mist
  • Works up to 16 hours
  • Good for a home with large rooms
  • 7 light colours


  • Noisy
  • Awkward grip to open
  • Not portable

VicTsing Homasy 500ml

The VicTsing Homasy oil diffuser has a stylish rounded design with a flat top and a large lighted area. It is available in white or white with a light wood grain finished base.

The Homasy by VicTsing offers advanced settings that give you plenty of options to enhance your room’s environment. It has a soft and strong mist mode, a timer that can be set for up to 10 hours at a time, an automatic shutoff when the tank empties, and a convenient sleep function. When activated, the Sleep function turns the light off, reduces the noise it produces, and emits a finer, more subtle mist. However, it’s still super quiet on the strong mist output mode so you shouldn’t anticipate any disrupted sleep.

In addition to all of the settings, the Homasy features eight different light colours that can either be set to steady or to cycle through the spectrum continuously. It has a large tank capacity of 500 ml meaning it will work well in larger spaces. On low mist mode, the Homasy will run for as many as 20 hours at a time.

This VicTsing oil diffuser does have some negative feedback involving water leakage so it’s important you don’t overfill the tank accidentally. Additional criticisms include a tricky lid closure that takes some getting used to and it not being portable. Finally, there are some discrepancies about whether or not it comes with a warranty so we would recommend checking with the manufacturer before making a purchase.


  • Up to 20 hours of use
  • Good for large rooms
  • 8 light colours
  • Timer function
  • Sleep mode


  • Reports of leakage
  • Tricky lid closure
  • Not portable

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, an 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 their 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.


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 number one Editor’s choice before you make your final decision.

The VicTsing 300 ml capacity essential oil diffuser has a medium size that will scent a fairly large-sized room in your home. It is available in both a light and dark wood grain finish, has four timer settings and an auto shut off function for safety. What’s more, it can run for up to 10 hours of use and even comes with a two-year warranty. We love the versatility that it has to offer with the 15 varying light colour modes, and the option to set it to spray continuously or intermittently.

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. So what are you waiting for? Make a decision and you too can start enjoying the benefits of an essential oil diffuser in your home.
