10 Best Car Diffusers UK 2024

How cute is this mini diffuser from DERSHARA? Aside from looking good, it works extremely well, providing a strong vapour stream of your chosen scent. Furthermore, it has an LED light function that can be turned on or off, depending on your mood.

While we love the pastel pink design, it's also available in black for those who prefer more muted tones. Perfect for use in your car or around your home, this affordable yet brilliant quality diffuser takes our coveted top spot! 

One button controls everything on this diffuser, making it effortless to use. It runs for an impressive 8 hours on a single charge and has a tilted nozzle so that you can angle it according to your preference.

If we're being really picky, it can sometimes be tricky to unscrew the lid to refill the water tank - but this also goes to show how leakproof it is! All in all, this is an excellent value diffuser that's sure to leave your car smelling amazing! 

This diffuser might be one of the smaller options on our list but it certainly does the trick when it comes to producing lots of fragrance. The buttons are easy to use and the device lasts for around 3 hours before it shuts off - assuming the water doesn't run out first!

The only thing to be cautious of is that the light function is quite bright, which some may find distracting when driving at night. It can be turned off though, so it's not a huge deal!

This diffuser has a long-lasting rechargeable battery which should provide you with 6 hours of mist on the intermittent setting. It has a huge 320ml water tank and a silicone non-slip base to ensure that it stays securely in place when you're on the move.

The only real fault we can find with this diffuser is that in some car models, it's slightly too big to fit the cup holder. Other than that though, it's a great buy!

We love the minimalist black and silver design of this diffuser by HoMedics, which delivers a fine mist of fragrance for 6 continuous hours or 12 hours intermittently. The colour-changing light will help you to relax - it should even prevent you from experiencing road rage!

Powered by a USB cable, this diffuser is uncomplicated and can be used in your home as well as your car. It doesn't really have any special features though, which is disappointing - especially since it's the most expensive product on our list!

This diffuser is compact in size but still offers 3 hours running time when left on the continuous setting. Although its main power source is a USB cable, it's also supplied with a 12V adapter which makes it great for charging on the move. 

Strangely, this diffuser occasionally interferes with DAB radio signal which may be worth taking into account if you like to listen to tunes while you drive. Moreover, it can become clogged with oil easily, so regular maintenance is essential if you want things to run smoothly!

This diffuser from Dricar has a good-sized water tank and a timer function, meaning that it automatically turns off after 4 hours. The 7 colour-changing light modes make this a fun product to use and the coffee cup design means it slots neatly into your car's cup holder. 

Sadly, this diffuser requires more essential oil than most to get a decent mist, so you may find yourself needing to buy oil more frequently. It also doesn't last very long after charging, so we suggest keeping it permanently plugged in via the USB cable. 

This 12V socket diffuser from MASO has a 2 hour run-time with an auto shut-off when the water level gets too low. In addition, the vapour outlet has a fully adjustable angle, allowing you to you position it exactly how you want it. It also features 2 USB ports which is a really handy extra - especially if you want to charge your phone or run your satnav as you travel.

Sadly, this diffuser doesn't have an intermittent function, so you'll have to turn it off when the fragrance gets too much. The head is also quite heavy when the tank is full of water, which can make it tricky to position properly. 

This diffuser from Sichy will last up to 3 hours wirelessly after a single charge or up to 8 hours if used with the cable. It automatically shuts off if the water level gets too low and it promises to be totally leakproof, so there's no need to worry about spills as you drive. It also features colour-changing LED lights which is a cool feature!

The only downside is that the charging cable supplied with the unit is fairly short, so you'll have to set up the diffuser right by the USB port.

This diffuser from Qrity spritzes 25ml of fragrance per hour and shuts off automatically after 2 hours, so that the unit isn't damaged when the water runs out. It's totally leakproof, with a swivel head that allows you to position the vapour stream at an angle that's just right for you.

While this is an affordable option, it's far from perfect - the controls are rather fiddly and the scent it produces is a tad weak. It's also worth bearing in mind that the essential oils used with this product must be water-soluble, otherwise the mechanism can become clogged.
