Diffusing essential oils is one of the best ways to enjoy all these natural wonders have to offer. It allows you to effectively have the oils working for you constantly wherever you are. Diffusing allows the aromatic and therapeutic properties of the oils to go to work while you get on with life.
The best essential oil diffuser will vary for depending on personal preference, usage and environment. There are several types of diffusers for essential oils and it may be that you decide on a few different models for a range of situations.
Some are more portable, require no water and can quickly fragrance a small space. While others require water and are better for larger spaces. Further, the way in which they disperse the oils varies which can slightly reduce the therapeutic effectiveness of the oils. This may not be a concern if you are primarily interested in the aromas.
To help decide which is the top essential oil diffuser for you, I have put together this list of the best on the market, along with an outline of the types of models available. From this, you will be able to start enjoying the smells of essential oils very soon.
But first, let’s get an understanding of diffusion and how diffusers work.
What You Need To Know About Diffusing Essential Oils
1. How Diffusion Works
When deciding on the best aromatherapy diffuser, it is important to first understand exactly what a diffuser does and how diffusion works.
Diffusion is a process that puts a fine mist of essential oils into the air, making them available for inhalation. Once dispersed, the oils can remain suspended for several hours and go to work freshening and improving the air quality.
As we breathe in the oils, they go to work on our mind, body and spirit by delivering a host of emotional and therapeutic benefits. These benefits will vary depending on the blend of oils used in the diffuser.
2. Why Diffuse Essential Oils
Diffusing essential oils is one way to make the properties of the oils available to our mind and body. Essential oils can also be inhaled and applied topically. Watch the video below to better understand why you should diffuse essential oils.
The fine mist from diffusion allows us to inhale the oils. Because our sense of smell is directly linked to the brain through the olfactory system, this is a powerful way to affect memory, emotions and hormones through the olfactory system. The incoming aromatic molecules enter the body via the nose with every breath and will enhance emotional wellness, relax or rejuvenate.
Inhalation also allows the essential oil molecules to enter the respiratory system. From here they are carried into the bloodstream and circulated to every cell of the body. Within the cells, the essential oils can activate the body’s ability to heal itself and improve health.
Apart from the benefits directly to our bodies, diffusing essential oils can help to reduce airborne chemicals, kill bacteria, reduce fungus and overall greatly improve the air quality.
3. Types of Diffusers
The best types of diffusers maintain the chemical makeup and therapeutic qualities of essential oils. Those that require an intense heat source e.g. light bulb ring, candle, can alter the essential oils and as a result are not ideal.
The recommended diffusers for essential oils are:
Evaporative (or fan) – air is blown over a pad containing the oil to create a mist
Nebulizer – burst of air breaks the oils into a fine mist of smaller molecules
Humidifier – vibration and air vaporize oils combined with water to create a cool mist
Ultrasonic – ultrasonic vibrations convert oil mixed with water into a fine mist
Each of these works slightly differently with some requiring water (humidifier, ultrasonic). Evaporative diffusers are the most portable and some models can run on batteries. While nebulizers are considered the best in terms of maintaining therapeutic benefits, they are the most expensive.
The most popular diffusers on the market are ultrasonic because of their affordability and the wide range of choices available.
4. Essential Oils to Diffuse
All essential oils can be diffused either alone or in combination with others. However, some of the more viscous oils e.g. myrrh, sandalwood can make some diffusers difficult to clean and are better avoided in those models.
When first starting to diffuse oils, it is best to start with those that have a variety of benefits and will form the basis of any aromatherapy kit. These include lavender, eucalyptus, lemon, peppermint and geranium.
Extending from this consider what you are trying to achieve with your diffusion. Is it to give your memory a boost? Fight coughs and colds? Or simply to make the house smell great? There are so many wonderful blends to experiment with and try. Keep it simple to start with and get more adventurous as your experience develops.
