What are Essential Oils?
Made from the parts of plants, essential oils are typically distilled from the petals, leaves, or stems. Although technically not in the scientific category of “oil” because they are actually a concentrated hydrophobic liquid that comes from the “essence” of the plant. Essential oils give off the strong aroma of the plants they are made from, and they are often used for various natural health purposes. According to many aroma therapists and natural medical practitioners, essential oils can help with dozens (if not hundreds) of different ailments, symptoms, and injuries. Most essential oils are used topically, some can be taken orally, and almost all of them can be diffused into the air for the benefits of aromatherapy. Whether looking to relax with lavender or clear a stuffy nose with peppermint, diffusing essential oils can bring a plethora of benefits to mental and physical health. Essential oils have micro-molecules which make them easy for them to be absorbed by the skin or projected into the air.
Why Do I Need an Essential Oil Diffuser?
In order to get the most out of your essential oils, you’ll want to be able to diffuse them into the air so that you can breathe them in to absorb the benefits into your system. The benefits of aromatherapy are many, including effects on the mental health as well as the physical and even the spiritual. Although scented candles have been the aromatherapy choice for many people, there are many reasons that this is not ideal based on concerns about toxins as well as the safety of an open flame around smaller children. A much more effective way to make your home smell good—and get the added health benefits of essential oils—is by using an essential oil diffuser.

Types of Diffusers for Essential Oils
Usually when people talk about purchasing an essential oil diffuser, they often mean an electric one. These are the most popular, and typically the most effective, and there are four different kinds of them. There are also two other types of tools that are used for diffusing essential oils into the air and those are either in the form of a Reed Diffuser or a Necklace Essential Oil Diffuser. Useful and effective in differing circumstances and for different reasons, information about all of these essential oil diffusers will give you a better grip on how to choose what will meet your needs.
Electric Essential Oil Diffusers
Three different types of essential oil diffusers exist that run on electricity of some sort. Most of them work by plugging into the wall, although there may be travel sized options which are battery powered or even plug into the electricity source in your vehicle. The three main types of electric essential oil diffusers are Ultrasonic, Heat, and Nebulizer.
Ultrasonic Essential Oil Diffuser
Creating a fine mist which is diffused with water into tiny particles in the air, an ultrasonic diffuser is one of the most effective essential oil diffusers for the cost. This type of diffuser also provides humidifying effects because of the water particles that are emitted into the air with the essential oil. This is particularly beneficial in winter months when the air is dry and needs moisture. There are a variety of brands, colors, and style options to choose from in the category of Ultrasonic essential oil diffusers. Do be careful in making a purchase of an ultrasonic diffuser because many of them have lights and if you plan to use them at night then you’ll want to make sure that the lights can be turned off.
Many fans of ultrasonic diffusers find that they disperse negative ions in the air, which are believed to be healthful by reducing stress, increasing the flow of oxygen, increasing concentration, and even eliminating headaches.
Nebulizer Essential Oil Diffuser
Most likely running on the pricier side of the list as diffusers go, a nebulizer offers the ability for the molecules in the essential oil to be broken down into even smaller particles in order to allow them to be absorbed by the body more easily. Nebulizers have a base that holds the motor which releases the oil particles into the air, as well as a glass container which holds the essential oils throughout the process. The extra money may be worth it if you are die hard essential oil fan, because these models can be well worth the cost as they are exceptionally effective.
While nebulizer essential oil diffusers are effective and convenient (because they don’t use water), they are also louder than ultrasonic or other diffusers. In addition, nebulizer diffusers use essential oils more quickly than others so there is a higher cost of usage, however, with the longer lasting results this may balance out the cost.
Heat Essential Oil Diffuser
Using heat to diffuse essential oils into the air is not the most effective form of diffusing, but some people do like them. The good thing about heat diffusers is that they are completely quiet, and the heat might help the oil to diffuse more effectively throughout the air. However, if a heat diffuser gets too warm, it can damage the effectiveness of the essential oil which means you must be very careful with the type that you buy. One somewhat effective heat essential oil diffuser is the kind that can be used in the small space of a car. When you use a diffuser that will plug into your car lighter, there may be less heat emitted and you’ll likely find that it works much better than any kind of car air freshener on the market.
Other Types of Essential Oil Diffusers
For those who want to get “unplugged” whether you are going camping or you simply want to never be without your oils, try these types of essential oil diffusers which do not rely on electricity in order to get the job done. Certainly less effective overall than the electric models, they will do well in a pinch when you are away from home, and they are likely to be significantly less expensive than their more powerful counterparts.
Evaporative Essential Oil Diffuser
Sometimes referred to as “Reed” essential oil diffusers, Evaporative diffusers are very simple and have likely been used for years even before electricity existed. Simply placing a few drops of essential oil onto a porous surface, or placing the bottom parts of porous reeds into a jar filled with essential oil. Sometimes a fan is used to send the scent into the air more effectively. Although simple and requiring very little maintenance, this probably one of the least effective forms of diffusing essential oils.
Working in the same evaporative way as the reeds, this fashionable jewelry is designed for you to be able to carry your healthful essential oils around with you wherever you go. Typically these necklaces are made in the style of a locket that hold a small pad on which drops of essential oil can be placed. This allows you to wear your oils around your neck and experience the benefits of your own personal essential oil diffuser. Essential oil diffuser necklaces come in all shapes and sizes.
