Try to imagine yourself walking on the morning grass, hearing chirping birds and smelling various flowers around you. How does it feel? It is amazing, isn’t it? Even being among the flower fragrances in the garden and smelling nature around you is a soothing experience for everyone. Obviously, if you spend some minutes in a garden, smelling fresh flowers, it will help you to become free from stressful thoughts, soothe both your mind and your body, relax your nerves and muscles, and thus regain your internal health. Considering the health benefits of the fragrances of flowers and other plants, alternative medicine practitioners have extracted the “miracle elements” from flowers, plants and even trees, and named them “essential oils”.

So, What Are Essential Oils?

It is the extracts taken from such natural sources as stems, leaves, barks seeds, flowers or even whole plants (fragrant oils) and equipped with the positive energies that a plant has itself. At the moment, these essential oils or magical fragrances, if you like, are widely used for providing the wellbeing and treatment separately or just as an additional component to other therapeutic processes catalyzing the improvement of general health.

Essential oils are considered a miracle alternative medicine for treating nerve problems, skin diseases, and many others that have been caused by constant strain on muscles or stress. The best way to use these essential oils is taking them as fumes dispersed into the environment. For this purpose, certain appliances are available on the market nowadays that are used to produce fumes by dispersing essential oils into the surrounding. We know these appliances as essential oil diffusing units. There are different types of these units available depending on the way of effecting the oils for fumes’ production.

Types of Essential Oil Diffusers

There are many different types of diffuser styles and brands available, but mainly they can be divided into following types:

• evaporative

• ultrasonic essential oil diffusers

• diffusing through heat

• nebulizer kits

• candle based diffusers

• reed oil diffusing kits

Of course, all these types produce the needed essential oil fumes. However, the fume nature can be affected by the way these fumes are produced. Thus, all these diffuser types differ in how the oil will affect you. Let us consider each of above-mentioned types of diffusers separately.


In such types of products, oil is evaporated into the environment due to heating of pads on which it rests. If you need only a light fragrance in the room, this type is the best one for diffusing oils. Since the heat may decrease the effectiveness of the produced oil fumes, this appliance may only be useful in making your room fragrant, and there may not be any health benefits of the essential oil in it.

The ultrasonic essential oil diffusers

In these machines, the essential oil put into it is diffused due to using ultrasonic energies. These waves evaporate the oils in the state of mist into the air. These appliances have been proven to provide a good aroma effect for those who are using aromatherapy. However, the essential oil health benefit may be lowered by breaking it down while diffusing with the help of these machines.

Heat diffusers

This type is simple in its function. The oil placed in it is just heated, and thus vapored and spread around the place. You can easily get sufficient fragrance in your room using these appliances. However, the chemical composition of the oil is affected due to heating so that you may not get the needed health benefits. These units are quite good in creating a calm atmosphere with soft aroma at your place.


This type of diffusers is considered the most effective machine for essential oils since they create oil microdroplets that are then sprayed into the air without any chemical change. These droplets last longer compared to the fumes produced with the help of heat based or ultrasonic diffusing appliances. Moreover, they contain oils in their natural form and have maximum health benefits you may get from any essential oil.

Candle oil diffusers

Thanks to their stylish design, candle oil diffusing units are often used as a piece of decor in rooms and spas for creating a soothing environment. The candle, under which the oil is placed, slowly burns and helps to release the fumes into the air. However, these appliances may not diffuse the aroma over a large area since they produce it in small limited portions.

Reed oil diffusers

As you can guess from its name, a reed diffusing appliance has reeds to disperse fumes into the air. These reeds are placed into the oil in the appliance and the oil flowing to the reed top is released into the air. These machines may not produce much aroma quickly around your room since this process is quite slow.

Why Is It Important To Have an Essential Oil Diffuser?

If you still do not know whether you need an essential oil diffuser or not, we will try to help you to get rid of this confusion. Of course, you may just have that fragrance bottle in the room and think that you will get all the aromatherapy benefits, but it is not right. If going through an aromatherapy is one of the parts of your medical treatment, you should take it seriously. Even going through an aromatherapy with required regular aromatic fumes, you should consider having an appliance that will meet your needs effectively. These are some reasons for buying an aromatherapy diffuser:

• You want to create a fresh and soothing environment at home.

• You want to relax using natural aromatic oils.

• Due to suffering from stress, you need to go through aromatherapy regularly.

• You need to clean up your surroundings from infectious viruses and bacteria.

How to Choose the Essential Oil Diffuser That Will Meet Your Needs the Best?

An essential thing that you should consider while buying a diffusing appliance is to decide which one is the best for your use. To do it, consider following important things:

• For what purpose do you need to purchase an essential oil diffusing appliance?

• How much area should it cover?

• Which oil will be used or is prescribed to use for medical treatment?

• What results do you need?

You should decide on these issues before choosing any product since it will help you to purchase the exact machine that will bring you the best results. You may get some idea here:

Nebulizer diffusing machines are the best for long lasting aroma and maximum health benefits.

Ultrasonic diffusing machines are the best for getting health benefits and a continuous and equal aroma distribution around a large area.

Vaporizing diffusing machines are efficient in providing light fragrances causing slow effects on your mood and good for small places.

Reeds and candles are the best when used around a very small area where you will relax or meditate

How Different Types of Essential Oil Diffusers Should Be Used?

Buying a diffuser for your essential oil is not all what you need. The most important factor in helping you get the desired effects is its correct usage. To use your appliance correctly, you should know its functions and features as well as the results you need. For example, if you need to fill a large room with your favorite smell, you need a nebulizer diffusing machine placed in the middle of your room. In contrast to it, you may use a vaporizing or candle oil diffuser if you need to fill a small area with the essential oil fumes. Consider these basic points of the right essential oil diffuser utilization:

• Always follow the guidelines that come with the appliance to use it properly.

• Always put a proper amount of oil into the diffusing machine.

• Place the machine in a correct position for getting the desired aroma spread.

• Never use it for long periods of time.

• Never leave the appliance turned on if it is empty or does not have a proper amount of oil in it.

The choice also depends on the needed effects. If you want to get all health benefits from any chosen oil, an ultrasonic oil or a nebulizer diffusion appliance should be used.

What Should You Avoid Wile Utilizing an Aroma Oil Diffusing Appliance?

The health benefits of these oils are significant and proven to be efficient in alleviating symptoms of mood disorder, side effects of medications, stress, and pain. However, using them continuously or in a wrong amount may be harmful to your health in many ways. Never leave the diffusing machine working for long. Otherwise, you will experience “olfactory fatigue” because of the constant exposure to the smell. Hence, you may feel insensitive to some smell or dizzy. Never use a unit regularly right from the start. Start using it in intervals. For example, one day you may use it for about 15 minutes only, the next day you may use it the same period of time but twice a day. Then use it according to the time and frequency prescribed you by the aromatherapy practitioner.

Where Can You Buy an Essential Oil Diffuser?

If you have made up your mind about which oil diffusing appliance is the best one for you, but still do not actually know where it is better to go to buy it, the best variant would be to look it up on an online store. You may find a great deal of online shops and stores offering and claiming to provide you with the best product you have chosen. However, always look for trusted shops that have plenty of positive customers’ feedback and offer the products of guaranteed quality. Of course, you can buy a diffusing appliance to be used as the aromatherapy partner, but be sure that it is not a blind decision. Be sure that you select the best appliance for you that will meet all your requirements perfectly. Choosing from a variety of diffusing machines online, keep in mind that each machine has different features that will cause a different effect on the health and environment depending on its function mode and used oil.
