Cars are like magnets for bad smells. If you’ve ever been in a car after a wet dog sat on the backseat you’ll be able to smell that musty scent for a long time afterwards. It’s also easy to guess what the driver last ate in the car, as those burger smells just ain’t going away, even if he or she left the windows open. A car is essentially a small metal box with smell-absorbing materials such as plastic and fabric, so it’s always a bit baffling why people choose to mask nasty old smells with chemical air fresheners.
Enclosed spaces provide the perfect opportunity for pleasant smelling products, and there is no better way to make your car smell better than to use natural essential oils. Essential oils are best used with an aromatherapy car diffuser. Not only are these products specifically designed for this purpose, but they look great in your car too – which means no more stinky magic trees hanging from your mirror! There are hundreds of car essential oil diffusers on the market, and not all products are created equal. So, we’ve taken on the task to find the very best products for your car and present them to you with the best features highlighted.
Here are our best car essential oil diffusers:
The Best Car Essential Oil Diffuser
This car diffuser has been designed with the perfect shape in mind. The handy vehicle cup holder design means that it’s simple to keep in place while you’re on the move. The car essential oil diffuser works with a USB connection so you simply plug it into your car to create beautiful scents in your vehicle and maintain a super fresh environment, free of moisture and odors. Unlike essential oil diffusers that are designed for the home, this particular model has the mist modes and switch buttons on the top so it’s easy to operate while driving. There are two modes on the diffuser: continuous and intermittent. This is a BPA-free product, which means that it does not contain bisphenol A – a harmful chemical that is often used in plastics. It also has a nice safety feature: the intelligent automatic off switch, which means that the machine won’t keep working “dry” when the liquid runs out. There are seven color-changing LED lights that can relieve fatigue driving or can be switched off if they are a distraction.

There is an automatic shut-off feature to stop the diffuser once it’s dry, and it’s easy to use in your car. We also like that this product has seven mood lights that can be used while driving – they’re super subtle too.

Best Car Essential Oil Diffuser Buying Guide
There are lots of different types of diffuser and it can be difficult to know which are the best car essential oil diffusers to buy. Below, we have written a guide giving you tips on what to look for when buying a new car diffuser. We’ll also tell you how to safely use essential oils and answer your most commonly asked questions.
What to Look for In a Car Essential Oil Diffuser
There are several things that make a good car essential oil diffuser. This is what we believe are the most important features:
No doubt the most important feature. If you are planning to use the essential oil diffuser inside your car then you are going to have to find a product that is portable and designed to be used in cars. No use buying a traditional oil diffuser that has a standard plug connection. Look for portable diffusers that use a USB connection. These are easy to use in cars and are versatile to be used in the home and office too.
Opt for a BPA-free diffuser. This means that the materials used in the design are less toxic and safe for family use. If you are planning to use this in a car then the last thing you want to be doing is pumping chemicals into the space. Look for safety features such as an automatic shut-off too which turns the machine off when the liquid reaches below the low-water level.
The larger capacity the more time you will get before you have to refill the diffuser. But look out for the measurements on the larger capacity products to make sure they will fit comfortably in your vehicle cup holder.
Not only should your oil diffuser perform well, but it should look good too. There are lots of nice sleek designs out there to choose from. From a practical perspective it’s good to opt for a design that will fit into your vehicle cup holder.
Some car oil diffusers feature lights and many provide a button which can make the colors change. This can be a really nice feature in your car if the effect is subtle. Otherwise it can be a distraction. So, as a general rule, the brighter the lights are, the more suitable they are for your home and not your car.
- Ease of Use
There’s no point in buying an oil diffuser if it impossible to use, or worse still…fiddly. Look for diffusers with simple buttons on the top so that they are easy to use whilst driving.
Don’t buy the cheapest on the market, whatever you do! Always go for the mid/top range products that offer value for money and a robust design.
Why You Should Use a Car Diffuser
There are many reasons why you should use a car diffuser. Firstly, standard air fresheners are full of chemicals and often make bad smells in your car smell worse. Using a car essential oil diffuser means that you can add your favorite scents and fill your car with natural smells. Essential oils have medicinal benefits too. To wake you up in the morning you could add orange oil drops mixed with grapefruit and if you need to wind down after work, why not try lavender? Be careful though as essential oils are strong and lavender can make you sleepy!
Using an oil diffuser also improves the air quality. By adding moisture into the air you can prevent dry skin and eyes and prevent a cough.
How To Use Essential Oils
Aromatherapy has been around for a very long time and it is no longer seen as a “hippy” thing to do. More and more people are coming around to the idea of essential oils and using products which are natural and organic. We’re all a bit over chemical products. The power of essential oils should not be underestimated. If you’ve ever smelled orange oil or peppermint oil when you’ve felt tired then you’ll know how it can instantly make you feel awake. On the contrary, lavender can really relax people and help with stress and anxiety.
There are many different ways to use essential oils. Traditionally they have been used for massaging and are always mixed with a carrier oil such as almond oil. However, when you use essential oils in oil diffusers you must only need to add a few drops to water – unless you have a waterless diffuser.
Do your research first and find out what are the best types of oils for your needs. Are you looking for something to give you more energy? Perhaps you need something to help you feel calm? Find out what the oils do before you add them to your diffuser and only ever use a few drops at once.
Best Car Essential Oil Diffuser FAQ:
Q: How long does an essential oil car diffuser last?
A: The answer to this question depends on a number of different factors. Firstly, how much does the diffuser cost? If it is a bargain basement product then it’s not going to last very long. Buy the best quality you can afford and look for a product with a warranty. If you take care of your diffuser and make sure you don’t clog it with cheap oils, you should have it for a good while.
Q: How can I make my car diffuser last longer?
A: There are a few things that you will need to do to make sure you give your diffuser the longest life. Firstly, only use essential oils and don’t even think about using cheap fake oils or even worse…perfume. Never fill water over the water mark and clean them around once every couple of months. To do this, fill your diffuser halfway with clean water, add ten drops of white vinegar, allow the product to run for about five minutes and then drain, use a cotton swab dipped in vinegar to clean any oily bits and then rinse thoroughly.
Q: How long do essential oils last in aromatherapy car diffuser?
A: This is entirely dependant on the product – usually a few hours until the water has run out but this depends on your diffuser’s capacity.
Q: Do I have to use distilled water in car essential oil diffusers?
A: Nope. You don’t have to use distilled water. Room temperature tap water is just fine. However, distilled water will prolong the life of your diffuser – so, your choice!
