Air fresheners mask odors that cause unhappiness and irritability, but using essential oils with a car diffuser allows you to relieve stress-inducing odors naturally, opening up your sense of smell so that it does not interfere with your emotional state.

If essential oils are absorbed through the skin when applied topically, why wouldn’t they be absorbed through the nose when diffused in the air? The sense of smell is just as important to your well-being and health as touch and taste.

Avoiding Dirty Carpets

Carpets and seats absorb a lot of smells, especially if you have children or pets.

No More Pet Dander

If you’ve ever been around dogs or cats when they get wet or after going for a walk outside in the rain, chances are you’ve experienced their dander. The oils don’t have to be 100% pure, but they do need to be diluted so that you can diffuse them through your car or at home for this purpose.

As well as being uplifting, peppermint oil is also very energizing and stimulating – it’s one of the best ways to clear away any sluggishness you might feel or give yourself an energy boost when needed.
