So this is what we’re all thinking: how does an essential oil diffuser work? At the most basic level, the best essential oil diffusers work by using heat, sonic vibration, or steam to transform the oil’s aromatic molecules into pure vapor or micro droplets that can be distributed through the air.
Most diffusers also emit a pleasant scent into the air, releasing essential oils and purifying the air, killing bacteria and fungus. Another health benefit is the essential oils that act like a fine vapor throughout the air so they can be absorbed gently into the body through the respiratory system. Importantly, the aroma can prompt the nervous system to transmit signals to the limbic system in the brain which is responsible for emotion and memory. So, the best essential oil diffusers will give you the same feel as smelling your loved ones perfume or the smell of entering a childhood home.
It is only fitting that we add the best essential oil diffusers for home on our list so that you recall the scent of a cosy environment as you enter. We have also some diffusers for your car and office to let you remain calm and feel happy despite the stress involved at work or while driving.
