Essential Oils are natural scent enhancers but can also add harmony, sleep stability, relaxation, freshness, focus, and have positive effects on our health from the inside too. We recommend purchasing Essential Oils from Reputable companies to truly experience the full power holistic plant smells. This Car Refresher is one way to eliminate toxic chemicals fromyou and your family's life.The most common Frangance boosters available are sheltered from disclosing the chemicals and products use to create their product fragrance. These hidden products are often found to contain harmful chemicals that can cause allergies and severe health problems. Sitting inside a car, often with the windows up, breathing these chemicals for extended periods of time can play a sneaky roll in the health of our families.
