What An Essential Oil Diffuser Actually Is?
To describe it in the simplest way possible, essential oil diffuser is a device that allows the essential oil to evaporate and give the air in the room a certain scent. They are a great aromatherapy solution, and can be combined with your favorite essential oil fragrance.
They can be pretty pricey, but there are also inexpensive options that can fit your budget. The most affordable option is the combination of diffusers and oils in a single package/product. They can come pretty cheap, if you consider that you get all-in-one type of deal.
You can find several types of diffusers; they vary by the way they diffuse the oil and by their purpose, and of course by the brand. So, you can see diffusers for kids, ultrasonic diffusers, heat diffusers and nebulizers. The ultrasonic ones are considered to be the best types because they don't need the heat for the oil to evaporate.
Some of the essential oil diffusers that do use heat tend to have a negative effect on the oil, so choosing the ultrasonic ones is a safe bet. Essential oils are mixed with the water which is vibrated and vaporized into the air. Because this process doesn't require the heat, oil's scent stays unchanged.
A lot of people want to know the difference between the diffuser and the humidifier because both use the water. The humidifier is made to be used just like that, and it's not cheap to use it to diffuse oils. The diffuser does a much better job in diffusing oils. And if you really want the aromatherapy and the humidity in the air, it's best just to use both of them.
Essential Oil Benefits
Essential oils have a lot of history. They were used in ancient times for a lot of purposes. They were used as a medicine, as a tool for rituals and for the aromatherapy, which is what they are used mostly for today. The benefits differ based on the types of essential oils, depending on what is used for the base of the oil.
- Eucalyptus scented oils are good for congestion and sore muscles. It's one of the most known scents for aromatherapy, and it can be beneficial for sinuses.
- Lavender is also one of the most popular options. And while it is used mostly for skin irritation treatment, the essential oils scented with lavender give the room a relaxing atmosphere.
- Peppermint is found in a lot of essential oils. And while you were able to see its use in beverages, it also increases the oxygen levels in blood, which is why it is used for essential oils. Its scent gives the room a refreshing atmosphere.
While these are the most popular picks, there are hundreds of other scents of essential oils. Pick the scent which you like the most. Some diffusers offer a possibility to change the different oils, and have in mind that even if they have the same scent, it may differ based on the brand.There is a lot of oils to choose from - see which are the best essential oils to diffuse.
Comparison Between Essential Oil Diffusers And Scented Candles
The first and probably the most important advantage of diffusers over scented candles is the possibility to choose over 100 different scents. Moreover, they are less expensive option compared to the candles, even when you take the electricity into account.
Some scented candles have health risks, while essential oils have health benefits. Even now it's a no-brainer that diffusers are the better choice. Add to that the ability to set the timer and turn the diffuser off automatically; you won't have to think even for a minute what is the better option.
Essential Oil Diffuser - Important Features To Consider
Considering that there are thousands of diffusers available today, some ground rules have to be set and features compared in order to differentiate the better diffuser from worse.
The first thing that will narrow down the search is the size of the room you want to put the diffuser in. Check the size coverage of the diffuser before getting it. There should be the estimated room size it covers listed on the description. The more coverage, the better; you can pick the one that covers even more than you need, since most of them have the ability to reduce the output.
The next thing that should be considered is the water capacity and the operating time. The operating time gives you the idea of how long will the scent stay noticeable in the room. The effective way to determine how long the air of the room will stay scented is to divide the water capacity by the operating time.
Check the diffusers' build quality as well. Some plastics can be damaged by essential oils, so diffusers that are made with cheap plastic won't last long. Diffusers which are of higher quality are mostly made of polypropylene or some other polymer.
Ease of use is the next thing that can make the diffuser stand out. Setup should be easy, replacement of the water and oils as well, and the maintenance.
The dimensions could also be important if you determined a certain spot in the room to put the diffuser on. They come in a number of different shapes and sizes.
Diffusers also have a certain noise level. Not all have the same. If you intend to use it in a quiet room, this feature might be important for you.
If a couple of diffusers come very close in all of the features above, then you can narrow the list down based on the additional features they have. Those can be a timer, auto-shutdown and ambient lighting.
Types Of Essential Oil Diffusers
Based on how they actually diffuse the essential oils, the diffusers can be found in several types. For you to get the idea how they perform, how they work, and their pros and cons, they will be listed below.
They are considered to be the most powerful essential oil diffusers. They don't require water or heat to diffuse the oil. Nebulizers use the atomizer to get the oil scent into the air. They can keep the continuous stream of oils in the room.
On the other hand, they can be quite expensive and quite loud. Nebulizers diffuse the oils by compressing the air and blowing it through the oil. They usually are made of wood and glass and are featured with ambient lighting.
With some models, you cannot then turn the light off, which is bad if you want to use it overnight and you don't like the lighting while sleeping. All of the nebulizer diffusers have the option to control the amount of oil being dispersed into the air. With most of them, you can control the intervals of spraying and the spraying time.
+ The oil is attached directly to the diffuser, and it's turned on only by one switch
+ They don't require any time to be set up
+ They are the strongest type of diffusers available
+ A lot of them come with timers
- They can be pretty loud
- They use up the oil much faster than other types
- The price to value ratio is not their best trait
Ultrasonic diffusers are quite similar to the nebulizing ones. They do, however, use water to diffuse the oil. They are not that strong like the nebulizing diffusers because the oils are mixed with water, but they do serve as a minor humidifier. It's important not to use citrus oils with these types because they can erode the parts.
Ultrasonic are the most popular type of them all. They feature a small tank of water where user puts a few drops of essential oil. They don’t use heat to diffuse the oil - instead, they have a diaphragm which vibrates and makes the water and oil mix and evaporate.
They are quite silent in operation, and the scent is a bit weaker when compared to the nebulizers. They are usually made of plastic, but there are wooden options available, which tend to be pretty pricey. Their water tanks go from 100 to 500ml.
The larger the water tank is, the more it will last, and you won't have to replace the water that often. Larger ones also come with the timer so they can be be turned on and off automatically. Some are advertised as real humidifiers, but they are not. They distribute only around 1l of water over 24h.
+ A lot of options available
+ Can be used as a minor humidifier
+ Pretty affordable
+ They don't use the heat to diffuse the oils
- Cannot be used to diffuse citrus oils
Heat diffusers use the heat to diffuse the essential oils. They function like the candle burners. This way of diffusing is effective but not the best one. Actually, it's the only type that doesn't leave the oil's scent intact. Heating the oils result in a slight change of their scent. They also cause the oils to evaporate quite fast.
You can see the details of oil burner vs diffuser battle in the following article.
+ The most silent diffusers of them all
- Fast oil evaporation
- Doesn't use electricity
- They change the scent of the oils
- No additional features available at all
Should People With Asthma Use Diffusers?
While you might come across some claims that diffused essential oils can help you breathe easier, this is not the case. If you have asthma, you should be careful, and the ultrasonic diffusers might be the best choice you have since you will be able to control the amount of oil they diffuse.
Although, there are no specific studies that show the effects of essential oils on symptoms of asthma. But, some oils can cause breathing troubles.
