Essential Oil Car Diffuser Types and Models to Choose From, with Pros and Cons


An American driving survey from 2015 showed that a person spends 294 hours/year driving. That is the estimated average time. It would translate into 7 weeks of a normal working schedule (40 hours/week). Source (table 6, page 14) 


This survey also shows that most of the driving (66.2%) is done without passengers. Now, when you put together these facts, it seems quite a lot of time to spend driving.


Some people enjoy doing it more than others. After a while though, the majority drives out of necessity and less from pleasure.


Thankfully, today we have new means of making driving less of a nuisance. Aromatherapy is what you need to make time pass by faster behind the wheels. Whether you’re on your way to work or going shopping, or even visiting someone in another state, there are ways to make driving more pleasant.


Thanks to the many different benefits of essential oils, you can feel relaxed or energetic. The trick is to never diffuse/inhale essences with sedating properties. That is a definite no-no when you’re driving.


Don’t fret though; I will tell you more about the best essential oil blends for a car diffuser after the reviews. Now, it’s time to get acquainted with some of the most affordable car oil diffusers. Check out their pros and cons (and price) before making a decision.

Why Use a Car Diffuser (Blend Recipes and Options)


I’ve given you the pros and cons of some very good looking and efficient car diffusers. Now it’s time to shed some light on why they are popular and useful. Plus, why do they even go so well with essential oils?


I will start with the last question. Essential oils are very concentrated plant extracts. There are literally tons of plants that go into a few hundred ml of essence. Their chemical profile is very interesting, and each oil has its own dynamics.


The geographical area of an essential oil influences its properties and benefits. That happens because the soil and the weather change the oil’s chemical composition. Then we add the way they’re harvested and processed, which changes that composition too.


That is why each new bottle of oil must be tested for allergies!


The diffusion and inhalation of essential oils act fast on the human brain and body. Those tiny active molecules are volatile. They disperse into the air and get into our system through the nose.


The nose processes them as hormones and sends various signals to the brain. If a molecule’s main effect is to inhibit pain signals, that’s what it’ll do after inhalation.


Essential Oil Car Diffusers


While diffusing essential oils in a car diffuser or any other kind, you will inhale up to 70% of the active molecules. That is the greatest concentration a person can absorb safely into his/her system. The rest will simply evaporate. The rate of absorption through skin applications is much less.


An essential oil car diffuser will disperse essential oil molecules into the small space of the car. You must always keep a window open while diffusing.


Studies show that inhalations which last more than 60 minutes can elevate the heart rhythm. That leads to elevated blood pressure, which makes a person anxious, agitated and stressed. If you diffuse for 30 minutes, the diffusion will last under an hour.


The air can easily get saturated because the oils are powerful. This can cause headaches or nausea.


Besides its therapeutic benefits, a car diffuser can also:


  • Purify the air.
  • Change the atmosphere and smell inside the car.
  • Kill bacteria and viruses, and prevent viral seasonal infections.


For all these reasons, I would recommend the use of an essential oil car diffuser. With the right blend, you can make driving easier and more enjoyable.



How to Choose the Right Essential Oil Blend for Your Car Diffuser?

You can use just one single oil fragrance in your car diffuser if you like. But you can also mix them together and create some beautiful new aromas/perfumes.


Before making a blend, consider the following questions:


  • What is the intent of the blend (energy, focus, relaxation, anti-anxiety, etc.)?
  • What are you in the mood for?
  • Will there be kids in the car?
  • Will there be pets with you?
  • What about ill or elderly people?
  • Is it for a long or short trip?
  • If you travel with passengers, what kind of perfumes do they like?
  • Are you or anyone else car sick?


All these questions may help you decide what kind of fragrance or blends to diffuse while driving. Sure, if you’ll be travelling alone, things will be much easier.


Also, keep in mind that in a car, you should never diffuse essential oils with sedating effects!



Essential Oil Recipes for Car Diffusers

Let yourself caressed by the natural fragrance of essential oils while driving. Lift up tension and anxiety behind the wheels. Boost your energy levels and recharge your batteries for when you get to your destination.


Soothe a migraine or a sore throat on the go. Keep your mind and body alert and relieve the fatigue caused by long trips. The list of benefits can go on, of course.


Choose from the following recipes and enjoy them in your new essential oil car diffuser.
