Essential oils have been around since the dawn of time, and today are one of the easiest and most pleasant ways to improve your overall wellness. Early Egyptians, Persians, and Greeks discovered many uses for essential oils, including for rituals and healing, as did people in other parts of the world. Back then, healers would prepare essential oils by infusing flowers, roots, and leaves in fatty oils, and apply the oily results directly to their skin or clothing.

While applying the oils on your body and belongings can work, the aroma and effects of the essential oils tend to wear off quickly, and the oils may leave a greasy residue. Fortunately, engineers have since learned how to deliver essential oils into the air, providing a long-lasting and convenient way of enjoying the benefits of essential oils.

What are essential oil diffusers?

Diffusers have revolutionized the way we use essential oils. Today’s diffusers make using essential oils easier and more convenient. Some diffusers convert essential oils into gas, while others use ultrasonic vibrations to break up the oils and disperse them like a mist into the air. With so many sizes and color options, there’s bound to be one that fits your needs.

What does an essential oil diffuser do?

Essential oils are broken down into smaller molecules by an oil diffuser, which then disperses these particles into the air. The smaller molecules permeate the air, filling it with delightful aromas – these tiny molecules also aid in the delivery of essential oils’ beneficial effects. Diffusers of today disperse molecules at a comfortable concentration that is easy to breathe and does not overpower the room. Back to top.

Do you need an essential oil diffuser?

No! You don’t need a diffuser to use essential oils. Here’s how to use essential oils without a diffuser.

Types of Oil Diffusers

Retailers offer four main types of oil diffusers. Each works in a slightly different way to diffuse essential oil molecules into the air, giving consumers a variety of choices based on the intensity of the desired effect and the specific limitations of their space.

Nebulizing Diffusers

Nebulizing diffusers use pressurized air to create a fine mist of oil. They feature a vacuum that pulls oil to the surface of a distribution tube to introduce a burst of aroma into the air. Nebulizing diffusers do not need heat or water, so they are low maintenance.

Ultrasonic or Humidifying Diffusers

Most popular are humidifying diffusers or ultrasonic diffusers. They use ultrasonic vibrations to break up oil molecules, thereby creating a fine, aromatic mist. To use an ultrasonic diffuser, simply dilute the essential oil with water. Because they use water to create the mist, ultrasonic diffusers work like cold humidifiers to add moisture to the air, which is particularly helpful during the cold, dry weather of winter. They are very easy to clean, allowing the user opportunities to use a wide variety of essential oils to support good health with confidence.

Evaporative Diffusers

Evaporative diffusers feature a small fan that helps turn oil into gas, which helps the oil evaporate into the air. On the downside, the oil loses some of its potency as it evaporates. Evaporative diffusers are a good choice for consumers who use essential oils only occasionally but want a fast, easy way to enjoy an aromatic sensation.

Heat or Electric Diffusers

Heat diffusers use heat instead of a fan to turn essential oils into a gas. Heating oil in this way can change its chemical properties to make the oil more or less intense, depending on the specific properties of the oil. Heat diffusers are quieter than diffusers that use fans. A number of different types of heat diffuses are available, including electric heat diffusers, candle diffusers, and lamp ring diffusers.

Manufacturers are now adding cool features, such as ambient lighting and sound. Automatic shut-off features improve safety, especially for consumers who use their diffusers for extended periods or in bedrooms or other living spaces where the users may fall asleep.

Engineers are creating diffusers that look as good as they work. Ceramic diffusers give the space a wellness vibe, for example, while diffusers with bamboo or marble-like finish add a dash of sophistication and elegance. USB diffusers plug into computers and laptops to infuse a pleasant aroma throughout the workspace. There are also diffusers that fit neatly into a cup holder, plug into a wall outlet, or sit unobtrusively on a desk or shelf. Some even work well for travel. Back to top.
