How to Choose a Car Diffuser in the UK - Buying Guide

To make sure you find the right diffuser for you and your car, there are a few different things to consider. We've put together this handy buying guide that's sure to come up smelling of roses - so read on to find out more!

Check the Dimensions to Ensure a Secure Fit

Most diffusers designed for vehicles are just the right size to fit comfortably into one of your car’s cup holders. This means that they'll stay upright and won't spill all over the interior.


If your car doesn’t have cup holders or if you'd prefer to keep them free for your morning coffee run, then you should check the dimensions of the diffuser. Knowing the size will help you to select one that'll fit elsewhere, like on the dashboard, and won't tip over while you're driving.

A Diffuser With an Intermittent Feature Allows You to Breathe Easy

Even scents we love can sometimes become overpowering, especially within the small confines of a car. Strong scents can cause headaches and sneezing, which is far from ideal when you’re driving about!


If you want to avoid feeling overwhelmed, opt for a car diffuser with an intermittent feature so that the fragrance isn’t continuously being released and you can have an occasional breather. This also prolongs the amount of time needed between charges, which is always a bonus!

Consider How Long You'd Like Your Diffuser to Run For

Some diffusers also have an automatic power-off function to prevent them from running for hours on end. This can be particularly helpful if your diffuser requires batteries, as leaving it on during a long drive may mean you'll run out of power!


The shut-off feature varies from product to product, with some turning off after just 30 minutes and others waiting up to 8 hours. If you tend to have a long commute or enjoy taking weekend trips where you'll be driving for hours at a time, this feature is a must! 

Picking a Diffuser That Uses Water Is Purely a Matter of Preference

Picking a Diffuser That Uses Water Is Purely a Matter of Preference

Whether you go for a diffuser with a water tank or not is purely down to your personal preference, as both types create a similar effect.


Diffusers with a water tank combine water and essential oil to create a lovely scented mist that'll keep your car environment smelling good and won’t dry your skin out. However, they need to be refilled regularly, as the diffuser will not be able to run without water.


Waterless diffusers blow air over essential oils and disperse this vapour around your car. While they don't require water, they produce the same kind of mist as products that do. Unfortunately though, they don’t add any moisture to the air in your car. 

Think About How Your Diffuser Will Be Powered

Think About How Your Diffuser Will Be Powered

Regardless of the type of diffuser you choose, it'll need a power source to work! The most popular option is the USB cable. This is used to charge the unit and can then be detached if you want to keep things wireless. 


If you don’t fancy having to remember to keep yet another device charged (phone, tablet.... the list feels endless!) then your car's cigarette lighter can be used as a 12V power socket. Products that are compatible with this type of power source are really simple to use, and the port tends to be tucked away on your dashboard which keeps things neat and tidy!

Tend to Travel With Your Pet? Be Aware of the Dangers of Essential Oils

Tend to Travel With Your Pet? Be Aware of the Dangers of Essential Oils

If you regularly travel with your cat or dog in your car, you should exercise caution when using essential oils in your diffuser. While a lot of essential oils are totally safe to use around pets, there are a few that you must avoid as they may cause your pet serious harm.


Potentially harmful oils include cinnamon, clove, citrus (d-limonene), eucalyptus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, ylang ylang, and thyme.


Exposure to these oils can cause health issues ranging from coughing and skin irritation to seizures and difficulty breathing. If you plan to take your furry companion on an adventure then definitely skip these oils in order to keep them safe!
