Types of Essential Oil Diffusers
The essential oil diffusers are divided into four major types, including nebulizing diffusers, ultrasonic diffusers, evaporative diffusers, and heat diffusers.
This type of essential oil diffusers requires you to dilute the oils in water which it releases into the air as a mist. It turns the water into mist by using electronic frequencies to produce ultrasonic vibrations that break down the molecules, allowing it to be distributed into the air as a fine mist.
These diffusers are the most commonly available type, with many models having advanced features like automatic shut-off and changing lights. However, this type needs frequent cleaning, and the scent might not be as potent due to the oil being diluted in water.
This type is available in tow variants. They include one with a fan and another one with existing air current. Evaporative diffusers come with a small fan blowing the air past the oil. As a result, it evaporates at a faster rate.
The fact is that the heavier components will disperse slower compared to the lighter components. Therefore, it’s not easy to utilize essential oil benefits fully. Although these models are less expensive and portable, they are not good choices for large space.
This type of diffuser relies on heat to distribute the essential oil into the air. Some examples of this kind are steam inhalers, candle burners, and electric heat diffusers. They are relatively simple to use and inexpensive. However, the heat can alter the composition of the essential oils and affect or even reduce their associated health benefits.
And, you needn’t worry about altering the nature of the essential oil. These models are just perfect for personal space. You shouldn’t consider it for a large space.
Unlike the other types of diffusers, nebulizing diffusers are seen as the best type of diffusers as they don’t require water or heat and use glass instead of plastic components. They work by using pressure to vaporize the oil into fine absorbent particles before distributing them into the air. With nebulizing diffusers, you get a higher concentration of essential oils, allowing you to fully experience their benefits.
However, the downside with this is that, compared to the others, it can be costly and difficult to clean.
This is one of the most favorite diffusers today because it doesn’t require heat or water. It comes with zero plastics. Actually, this unit works with pressurized air and oil.
This diffuser offers a small tube that allows a stream of air blows to go through. It pulls the oil to the surface into a fine mist. Therefore, the fragrance can reach anywhere of your space.
Benefits of Essential Oil Diffusers
Although there are other methods for using essential oils such as mixing it in with carrier oils to make lotions or sprays, using diffusers is still the most recommended way for maximizing the potential of your essential oils.
Some of its other benefits are as follows:
Creates your desired environment
Using an essential oil diffuser can help you achieve the environment that’s conducive to your particular goal. Diffusing lavender oil at bedtime, for example, can create a soothing and relaxing environment that will help you sleep better.
Purifies the air
Some essential oils have antibacterial and disinfectant properties, and the best way to maximize their potential is by diffusing them. Moreover, as it purifies the air, it can also help with respiratory issues like allergies and colds.
Effectively repels insects
There are also essential oils that are effective insect repellents, and diffusing them in your home helps clear it of disease-carrying insects like mosquitoes.
Frequently Asked Questions
Which type of diffuser is the best for large rooms?
The best types would be either a nebulizing or ultrasonic diffuser. When it comes to maximizing the effects of essential oils, the best option would be nebulizing diffusers. However, since they use pure essential oils, they can only run for a short time before you need to replace the oil.
Ultrasonic diffusers, on the other hand, don’t have this problem. They can come in large-capacity tanks so the scent lasts longer. They’re also easier to maintain compared to nebulizing diffusers.
What tank size is best for large rooms?
You will need a diffuser that can handle at least 300ml of water to properly cover a large area. However, if you want something that can last longer, there are diffusers with a capacity of almost 5 liters.
What is the proper essential oil-to-water ratio?
The recommended ratio of essential oil to water is around 3 to 5 drops of oil to 100ml of water. Any less would make the oil less effective and adding more can make it too overwhelming and do more harm than good.
An essential oil diffuser is often considered the best way to make the most out of your preferred essential oils and the health benefits they bring. While they come in many types, the most commonly found and best type for large rooms is the ultrasonic diffuser which uses water and electronic vibrations to diffuse the oils into the air.
Moreover, they also often double as humidifiers which can help with maintaining the air quality of your home, office, or other preferred space. With an essential oil diffuser, you can enjoy all the benefits of your preferred oils conveniently and hassle-free.
