We’ve all had a pine tree-shaped air freshener, dangling from the rearview mirror, spreading sweet forest odours around our car at some point in our lives. It’s a rite of passage for any car owner.

If you are anything like us you will have a fond attachment to this experience.

Even though having a sweet smelling vehicle is a pleasure on its own, modern aromatherapy technology has opened up a world of possibilities.

You can now diffuse essential oils in your car, giving you endless possibilities to fragrance your vehicle, as well as the associated health benefits.

Why Have An Essential Oil Diffuser In Your Car?

Stress Reduction and Circulation Improvement

Riding in a car can be a stressful experience, the space is small and claustrophobic restricting your movement for long periods. Sitting down for over an hour is bad for the circulatory system and can lead to blood clotting.

Having an essential oil diffuser spreading vapours can promote relaxation and reduce the stress of being confined for long period. Blends like lavender calm the heart rate and are perfect for this situation.  

You can also look at using ginger or black pepper in your blend as these improve circulation. Which helps to negate the effect of long-term sitting.

Enjoy Other Passengers Company

You may be wedged up in close proximity to other passengers, this can be particularly stressful if you have agoraphobia, using lavender in a blend is a great way to feel more comfortable in the company of others.

Or you may also be riding with passengers who are loud, smelly and opinionated (your annoying cousin for instance).

Reduce travel sickness

The movement of the car can induce motion sickness, this is a very uncomfortable condition to experience and can make traveling a nightmare.

But using a blend containing cardamom and grapefruit will help to stop you feeling travel sick.

Improve air quality

driving on busy roads means you’ll be breathing in a lot of air pollution. Air pollution has been shown to lead to breathing conditions, increased risk of Alzheimer’s and a shorter life expectancy.

Using blends such as eucalyptus oil can help reduce the impact of being in a polluted environment.

The particles in eucalyptus oil have been scientifically shown to attach to carbon dioxide particles and change them to less harmful by-products.

Indulge your sense of smell

The most obvious and instantly gratifying effect of using essential oils in your car is that they emit quite magnificent smells.

It cannot be overstated the simple pleasure of smelling a delightful aroma. Like slipping in to warm bath, or sipping a hot cocoa. Take the time to make sure your senses are given what they deserve.

There are a number of benefits to using essential oils in your car. From creating the desired atmosphere to improving physical and mental health or even just too pleasing your nostrils.  It really is a great way to help you get what you want out of life.

We highly recommend investing in one today. And we are going to help, by taking you through the best available options.

With that said, let’s get started. Here’s a list of the 10 best essential oil car diffusers and their reviews in 2019.

1. Mobile-mini

The mobile-mini is our stand out performer. It’s number one on our list and stands out in every category. A portable diffuser that boasts wireless charging, so there is no messing around with plugging cables in.

Its powerful lithium battery lasts for 18 hours, which is enough for even the longest stretched on the road.

The mobile-mini portable diffuser is a nebulizer diffuser, this is great for maintaining the integrity of the oils and for working in near silence.

The product is extremely well made. It is comprised of an anodized aluminum body and the reservoir is hand blown glass. It has a great substantial feel to it and an elegant silhouette.

The company are so confident of the quality of manufacturing the offer a one-year guarantee.

This diffuser is perfect for people who want a powerful diffuser to take with them on the go. It’s so effective that you can use it in larger spaces as well.

Perhaps you a yoga teacher taking lessons in different studios and like to treat your clients to aromatherapy, or your a masseuse that does home visits.

2. Nanum

The Nanum car essential oil diffuser is a product designed specifically to be used in your car. It connects directly to the charging socket so there is no need for an additional adapter.

It’s an ultrasonic diffuser with a 50ml tank that also doubles up as a humidifier. It triples up as a USB charging port, so you don’t have to choose between charging your phone or your essential oil diffuser.

The Namum diffuser has an appendage that extends from the charging port that can be filled with essential oils. It is made from plastic and coloured purple and white.

We really like the consideration the designers of this diffuser have taken to make it uniquely designed for a car setting, combining a diffuser, humidifier and USB ports.

It’s perfect for those who will only use the diffuser in their cars. Perhaps not the most elegant of visual designs, it is certainly one of the most functional products.

3. Tatuo

The Tatuo two-piece diffuser set is a very unique product. It is entirely non-electrical and does not need to be charged.

It clips into the air vent of your car and fits any model when you want a boost of aroma you just turn on the ventilation and it functions as an evaporative diffuser.

The Tatuo diffuser makes use of an absorbent pas that you will need to regularly replace. This set comes with 48 pads which should keep you going for a decent amount of time. You also get two in the pack making it a great value investment.

Made from stainless steel and resembling a badge the diffuser has a carved cloud and tree pattern, they are unusual and quirky.

The carvings spaces allow the aroma to come through and the felt pads come in a number of colour options to suit any car decor.

We really like the originality of the Tatuo car diffuser and how it makes use of the ventilation system in your car. Good value, but perhaps not most attractive car clip available.

4. Maroma Life

The Maroma life car oil diffuser is very similar to the Tatuo diffuser. They both clip into the ventilation system of your car and you get two in a pack with each. 4-5 drops of oil in this diffuser will last about 7-8 hours.

The main difference between the Maroma Diffuser and the Tatuo Diffuser is the look. The Maroma Life has a black matte metallic finish rather than the shiny polished silver finish of the Tatuo and we think it is less obtrusive and would more easily fit in with a car dashboard.

The Maroma diffuser also has a higher quality steel. That’s why we’ve given it a higher rating than the Tatuo offering. But functionally they are very similar and it really comes down to personal taste.

5. Royaroma

The Royaroma diffuser is a uniquely designed acorn shaped diffuser. It’s both ornamental and functional.

This diffuser functions more like the traditional air fresheners you fill the acorn with essential oil and then let the stopper absorb and then disperses the particles into the vicinity.

It is not electrically powered, which has the bonus of never needing to be plugged in, but it only offers a faint dispersion of essential oil aromas. Made from real wood, it is an eye-catching product.

This is a budget option that can be used anywhere. It would make a great gift for an aromatherapy enthusiast.

6. FreeZoo

The FreeZoo diffuser is an ultrasonic diffuser with a 50ml capacity. It’s charged via usb so you can plug it into your car charging socket. You will, however, need an adapter which is not included.

On a full charge, the FreeZoo diffuser can last up to six hours. The range the FreeZoo can cover is up to 30m which is ample for your car.

It’s modelled in a dark word and black metal combination, which would suit darker car interiors. It has a simple non-intrusive cylindrical shape and will fit into your car cup holder.

One of the better USB charged devices we have looked at and reasonable entry model for anyone looking to get into aromatherapy for their car. It’s well suited to use in a car or for taking on a weekend away.amazon button

It fits neatly into your car cup holder, keeping it well secured during bumpy journies. The shape of this diffuser is like a thermos flask and the copper coloured coating is very striking.

A well-made product, that fits in with a modern lifestyle, small enough to take anywhere, but big enough to pack an aromatherapy punch. This unit is great for new mothers and students.

This diffuser also boasts a 100ml capacity tank which is one of the largest we’ve seen for a portable diffuser.

The manufacturer also offer a one year warranty and a 40 day money back guarnattee. We really like that they offer this to their customers.

We really like the look of this model and the fact that it doubles up as a very effective humidifier. We’d recommend this product to those who would want a powerful portable humidifier to use in the car, office and at home.

What to consider when buying an essential oil diffuser for your car

Charging system

There are a few different types of essential oil diffusers that you could use in your car. One of the main differences between diffusers for your car is how the device is charged.

USB powered device

The first option is a USB powered device. This can be plugged into an adaptor that goes into your car charger. The advantages of this type are that it can be directly charged from the car.

You can remove it and take it with you, where you could power it from your computer, power bank or wall socket. This flexibility this gives you is a great bonus for selecting this type of charger.

We’d highly recommend getting this type if you are on a budget and looking to use your diffuser in places other than your car as well.

Powered by car charger

Another option available on the market is essential oil diffusers powered directly from your car charging socket. The plus side of these models is that you don’t have to fiddle about with adapters and they plug straight into your car.

It’s also worth noting that these types of diffusers are designed specifically to be used in your car, this makes them uniquely suited to the purpose.

A drawback of this type of diffuser is that it can only be used in your car and you can’t take it with you. We think this type of diffuser is best suited to those who know they only want to use it in a car.

Rechargeable/portable device

A further alternative option is to buy a rechargeable essential oil diffuser. A huge benefit of this type of diffuser is that it doesn’t need to be plugged in and you can take it anywhere with you.

That wooden cabin up by the lake? Take your portable diffuser. Going camping this weekend? Fill your tent with the scents of aromatherapy.  

These rechargeable diffusers come in various shapes and sizes, but we recommend a couple in this article that is specifically shaped to fit in your car cup holder.

Helping them be stable and secure and also in a prime location to spread evenly through your vehicle. These devices are either charged by a USB, which is great because you can charge them up from your car or from a wall socket.

The ones charged from a wall socket offer superior strength having more powerful batteries thanks to being charged from stronger electrical sources. Some of the upper-end versions offer wireless charging for ultimate ease of use.

We recommend portable devices to people who are on the go and like to take their aromatherapy with them, it’s the most versatile choice and the higher end versions offer the best quality aromatherapy.

We’ve explored a range of portable diffusers to suit any budget.

Analogue diffusers

The low tech offerings available are aromatherapy lockets that essentially work the same way as the pine cone air freshener. It’s basically the foam pine cone encased in a more durable shell.

The foam pad that absorbs the essential oil can be topped up with more oil or replaced when its use has been exhausted.

We recommend this type of diffuser for those on a budget and who want to explore the potential benefits of aromatherapy.

One innovative model that we have included in this list is an analogue diffuser, but it clips into the air vent of your vehicle.

Utilizing the airflow when you have the air conditioning or heating turned on. This turns it into an evaporative diffuser and vastly improves the efficiency of your diffuser.

It’s a really clever idea and a fine example of considered product design. We’d recommend this type of diffuser for car drivers who live in extreme weather environment and make use of their cars heating or air conditioning systems. These models are also very affordable.

What method of diffusion to use in your car oil diffuser

There are a number of different ways that diffusers work. We are going to elaborate on the essential information you need to know about different types of diffusers to be able to select one for your car.

Evaporative diffusers

This type of diffuser allows the oils to be absorbed into the air via evaporation. It uses increased airflow over an absorbent material to speed up the evaporation process

Nebulizer Diffusers

Nebulizer diffusers break down the essential oils into tiny particles which disperse into the surrounding area much more quickly.

Ultrasonic diffusers

This kind of diffuser uses vibrations to break down the oils and allow them to permeate into the atmosphere.

Analogue diffusers

These type of diffusers use an absorbent material and a large surface area to slowly dispense the oils into the air.
