Best Essential Oil Diffusers in the UK (2017)

Last updated: August 10, 2017

Essential oil diffusers not only make your home smell nicer, they can also make you feel more relaxed. Essential oil diffusers are a more natural, healthy and eco-friendly alternative to artificial air fresheners, and they’re a good option if you react badly to artificial chemicals.

Most of the diffusers reviewed here produce a cool mist which can help reduce congestion and relieve cold and flu symptoms—an added bonus. Many diffusers also feature a lamp, so they can be used as a nightlight.

How to Choose the Best Aroma Diffuser

Essential oil diffusers can seem very similar to one another, so if you’ve never bought one before it can be hard to know which one to go for. Here are some tips for choosing the best aromatherapy diffuser.

1. Consider the size of the room

If you’re buying an essential oil diffuser for a large room you’ll want something with a water capacity of 500 ml or more, as this will allow the aroma to diffuse better throughout the whole room.

If you’re buying something for a small bedroom, a water capacity of 100-300 ml should be fine.

2. Do you want additional features?

In addition to creating a nice aroma, many essential oil diffusers feature coloured lights that can add to the ambience of a room or be used as a nightlight for children. These lights can almost always be turned off while the diffuser is running, so you can buy a diffuser with a light even if you’re not planning to use it.

3. Look out for fake reviews

Unfortunately, many products sold online have inflated user ratings due to fake reviews and incentives given in exchange for positive reviews. If you see that a diffuser has lots of 5-star reviews with similar wording, it’s quite possible that they are fake. This doesn’t mean that the diffuser will be poor quality, but it’s something to be aware of.

4. Try to get value for money

Since many diffusers have almost identical features and designs your final choice will likely come down to price. If you know what features and water capacity you want, look for the best value diffuser that meets your criteria (provided it has received genuine positive reviews). Look out for discounts and offers.

Essential Oil Diffuser FAQs

If you’re interested in buying an essential oil diffuser you probably have a few questions about how they work, what they can be used for and the potential health benefits and hazards of using them. We’ve put together a list of the most frequently asked questions about essential oil diffusers together with answers to each question.

Health and Safety

Are essential oil diffusers safe around babies and children?

Pure oils must be kept out of reach of children as ingestion can be very harmful due to the strength of the essence.

Essential oil diffusers are safe for use in a household with babies or children, as long as they are used correctly. Use fewer drops of essential oil in your diffuser if you have a small child or baby, but do not use them in the room where the child sleeps. A humidifier would be the better choice, as these can be beneficial, especially in winter.

If any of the family members suffer with a form of respiratory disease, such as asthma, the use of a diffuser is not recommended; the intensity of the oils can inflame respiratory tracts inducing an asthma attack.

Pregnant women are also advised to use essential oil diffusers with the utmost care and with very diluted oils. Always consult your GP if you have any queries.

Are essential oil diffusers safe around pets?

Dogs and cats are more sensitive to essential oils and so it is important to be careful in your choice of essence; some oils are safe to use and others are not. If in doubt or if you have any concerns, contact your veterinary clinic for advice.

An ultrasonic diffuser dilutes the oils, making them less likely to pose a problem with your dog or cat, but you must keep the pure oils out of the way of your pets.

Are essential oils healthy?

Bottle of essential oilEssential oils have many healing effects, but again, they must be used properly and safely depending upon who uses them. Different essential oils have healing traits for a variety of ailments, so it is best to do your research on these and consult your GP if you are thinking of using essential oils. You can find out more about the uses of essential oils here.

The miss-use of essential oils can cause seizures in children (and some adults) and are not recommended for use in a household where any residents suffer from respiratory diseases. Again, ask a GP for advice.

Are there any side effects to inhaling essential oils?

A diffuser creates the most practical and safe way to inhale essential oils. By mixing the oils with water, you can inhale the diluted strength of the oil and will gently receive the healing effects. Please see more about the health benefits of different essential oils in the Are essential oils healthy? section of our FAQs.

If you are not sure of your reactions to essential oils, heavily dilute the mixture you put into your diffuser, use less drops of oil and the recommended amount of water. Negative side effects can include asthma attacks or similar reactions when the person is affected by respiratory disease already.

Do essential oil diffusers help with allergies?

Essential oil diffusers can help with allergies when using specific oils. A small amount of drops can be placed into the diffuser and the mist can be inhaled to help ease the effects of an allergy. It is suggested that lavender oil is one of the most effective for this. Other effective oils include:

  • Eucalyptus
  • Tea Tree
  • Peppermint
  • Lemon

Essential oils can reduce any pain or inflammation caused by allergies as well as help the immune system to fight the allergens which trigger an allergic response.

Working and Using

How do essential oil diffusers work?

Most essential oil diffusers use a mixture of water and oil to create a gentle, cool mist which doubles as a humidifier. The fine mist released into the air is then inhaled or absorbed into the skin to provide the healing properties of the chosen essential oil.

There are some diffusers available which do not need water to diffuse the oils, they use only pressurised air; these are called Nebulizing Diffusers.

How do ultrasonic diffusers work?

An ultrasonic diffuser uses ultrasonic vibrations to break the oil and water into tiny micro-particles and a small internal fan blows these out as a fine mist.

Using vibrations means the mixture of water and oil does not need to be heated, leaving the resulting mist cooling and the benefits of the oils are unhindered by any heat.

What can you use an essential oil diffuser for?

On a basic use level, an essential oil diffuser can be used to create a gentle, therapeutic scent in your home. Due to the healing properties of certain essential oils, you can also use the diffuser to benefit your health. Essential oil diffusers are said to stimulate brain functions and can help to enhance your mood, relieve pain, increase your energy and much more.

Diffusers which use water, can also act as humidifiers for your home which can be very beneficial in winter to keep the balance of moisture in your home just right.

There are different types of diffuser to choose from including Nebulizer Diffusers, Ultrasonic/Humidifying Diffusers, Heat Diffusers and Evaporative Diffusers.

How many drops of essential oil should you put in a diffuser?

How much oil you use is down to personal preference, however, it is recommended that you start with around 2-10 drops. When using an ultrasonic diffuser, you may choose to add more, as the oils are diluted by the water and so the strength of the scent is decreased.

How long can I use an essential oil diffuser?

It is recommended to only use a diffuser for short bursts of time to get the most benefit. Certain models have timer functions which allow you get the most from your diffuser, the best being 10 minutes on and then 20 minutes off. Diffusing essential oils for long periods of time does not have any extra benefits or effects and is just a waste.

The longevity of your diffuser can be prolonged by avoiding certain oils, as there are some that can corrode the plastic and essentially break the device. These oils include clove, lemon and cinnamon.

How often do I need to clean an essential oil diffuser?

This can be down to personal preference as to how often and when you want to clean your diffuser. However, it is recommended that you only clean your diffuser when you know you will not use it for an extended amount of time, or if you are changing to a scent that is completely opposite to your previous i.e. energising to relaxing.

General

Are essential oil diffusers and humidifiers the same thing?

Essential oil diffusers which use water, for example the Aptoyu 120ml Aroma Diffuser, can double up as humidifiers, so in that sense they could be used in place of a humidifier. However, regular humidifiers are not made for using with essential oils.

Essential oil diffusers are used predominantly for their therapeutic effects in the home or to create a mildly scented ambience, whereas humidifiers are used to keep moisture levels in the home regular. See our Humidifiers FAQs page for more info.
