Diffusing the Diffuser

What exactly is an essential oil diffuser? It is so simple, it’s genius. They have existed for centuries really. Historically, they were simple and less than visually appealing; utilized to cleanse a space or provide health benefits for families. Today, however, they range from aesthetically pleasing, to technologically advanced. A diffuser is a “tool” that is utilized to release essential oils into the air; such as those used in aromatherapy. We will dig into the types of diffusers a little later; so you can pick the best essential oil diffuser for your purposes. With our cultural trends leaning more toward natural and chemical free living; diffusers are rising to top of the list for many.

Best Essential Oil Diffuser Reviews

Diffusers versus Humidifiers

There is a vast difference between a diffuser and a humidifier. The most important difference between these two is the fact that a humidifier is used to keep the air moist. Diffusers emit a fine vapor into the air, which allows the essential oil to “cling” or be suspended. Diffusers are made specifically for essential oils; while humidifiers are used with water. While a humidifier requires the heating of water to develop the mist we associate with helping a cold or flu sufferer; diffusers do not all require heat to work. They are referred to as cold diffusers. Both have different goals as well. While a humidifier is designed to help with symptoms from cold, flu, or breathing issues due to dry air; diffusers work to combat problems ahead of time. They can help prevent problems ahead of time, by preventing fungus growth, eliminating bacteria, and generally improving mood and well-being.

What’s the Best Diffuser for You? Unlocking the Mystery

There are four types of oil diffusers on the market today.

Nebulizer Essential Oil Diffuser ReviewsNebulizing or nebulizer diffusers work by blowing air across the surface of the oil, creating a fine mist or spray. The essential oil is drawn up through a tube and the air does the rest of the work, dispersing the oil. Nebulizing diffusers are considered to be ideal for therapeutic purposes; they saturate the air in the most rapid fashion, achieving a quickly calming environment. Nebulizer diffusers do not use heat at all. This means that the essential oil particles are not altered in any way. They do use essential oils at a fast rate, due to the fact that the air is filled quickly by millions of fine droplets. It is smart to set a timer for this type of diffuser, it will prevent overuse of oils, and overwhelming your nose. This is a great choice for a large home or office; economical in that several diffusers are not needed to fill the space with the desired amount of essential oil.

  • Recommended for therapeutic use.
  • Best models offer timing settings to reduce use of essential oils.
Ultrasonic Essential Oil Diffuser ReviewsUltrasonic diffusers also create a fine mist but the creation of the mist is quite different. Ultrasonic diffusers create an ultrasonic vibration, through electrical pulses, to create rapid movement, usually under water. This vibration breaks down essential oils into particles that are then released into the air. Ultrasonic diffusers also require no heat to disperse its mist; thus, keeping the essential oil particles intact and unaltered. This type of diffuser releases more mist but only a small amount of essential oil. This is a perfect choice for someone who wants the benefits of a diffuser but who wants to be cost effective on the purchase of essential oils. It is comparable to a humidifier, in that it does produce a water based vapor. It is great for clearing lungs, works to prevent dry sinus, and can be very calming (some produce a gentle sound akin to water falling). They are great for bedrooms, especially if you like background noise as you sleep.

  • Best models create a soothing sound; perfect for those who require “white noise” to sleep peacefully.
  • Comparable to a humidifier, in that it creates a moisturizing vapor.
Evaporative Essential Oil Diffuser ReviewsEvaporative diffusers are very simple in how they operate; air is blown over a pad saturated in essential oils. The air blows the essential oil elements into the room and once the pad has dried, it is replaced with a new one. These diffusers are recommended more as healthy alternative to chemical based room deodorizers, rather than a holistic aromatherapy. The process, though simple, does not distribute the essential oil in its entirety. Lighter components are distributed, then heavier components, as the pad dries; this does not lend itself well to therapeutic use. It does however; make for an excellent source of inviting fragrance in one’s home. The scent is gentle and lasts much longer than non-essential methods. Evaporative diffusers also use a small amount of essential oil per pad, and pads do not generally require frequent changing. This is perfect for small spaces or to have in multiple locations through your home.

  • The most cost effective and simplistic in design.
  • Less therapeutic in its use, but still beneficial to all over wellbeing and relaxation.
Heat Essential Oil Diffuser ReviewsHeat diffusers do exactly that, they heat the essential oils, causing them to disperse and evaporate at a rapid rate. Heat diffusers that utilize candles for dispersion can be very aesthetically pleasing. They will rapidly fill any space with their aromas. They are generally not used for therapeutic purposes, as the essential oil particles are broken down due to the introduction of heat. This type of diffuser is best in small spaces; which can make for a beautiful addition to small intimate events. They do create a pleasant ambiance. They do “burn” through essential oils quickly but make up for that in the pleasant addition they can make to your home’s décor. They can be found in several varieties and sizes.

  • Not therapeutic in nature but can add significantly to the ambience of your home.
  • Comes in a variety of designs and sizes.
