Essential oil diffusers come in a wide range of varieties. Some are better than others, and some are best avoided. Save your money and make sure that you buy a diffuser that will work well and won’t break down after a few uses.
To make sure that you get the best essential oil diffuser, here is a list of the top diffusers that have proven to be able to work well and deliver on their claims.
The Top 10 Essential Oil Diffusers
1. URPOWER 2nd Version Essential Oil Diffuser with Adjustable Mist Mode
Small bedrooms, hotel rooms, office cubicles, and other small spaces can benefit well from this URPOWER diffuser. It features whisper-quiet operation, which means it won’t produce a low whirring noise that other essential oil diffusers produce. This diffuser is thus perfect for those who like enjoying the benefits of an essential oil diffuser, but don't like the noise.
Furthermore, the URPOWER Second Generation Essential Oil Diffuser comes with a variety of great features. It can function as a lamp that can switch between seven different colors. There is also an automatic shut off mechanism that turns the diffuser off once the water runs out.
Dry air in living spaces can affect a person’s health. It can cause or exacerbate health issues like asthma, dehydration, skin irritations, and more. With the URPOWER Second Generation Diffuser’s extra mist, however, you can make sure that the air you breathe has sufficient moisture.
Pros and Cons
URPOWER produces a number of the best essential oil diffusers on the market and is a particularly prolific manufacturer of diffusers, humidifiers, lawn and garden products, and more. The brand thus has considerable experience in designing and manufacturing diffusers, which is a plus.
The URPOWER Second Generation Diffuser can run for up to 6 hours when set on the intermittent mist mode, and up to three hours when set on the continuous mist mode. On the intermittent mist mode, the diffuser will cycle between emitting mist for 30 seconds, then stopping for 30 seconds.
One drawback, however, is that this diffuser can accommodate only 100 milliliters of water max. This might be too little for some, but since it’s meant for use in smaller spaces and can still work for 6 hours, this smaller volume can work just as well.
2. URPOWER Ultrasonic Essential Oil Diffuser with Adjustable Mist Mode
Another URPOWER diffuser appears on this list of top rated essential oil diffusers, and for good reason. This ultrasonic diffuser is highly effective and works like a dream, but is also designed to be easy and uncomplicated to use. It comes with just two buttons: one for controlling the color-changing LED mood light, and another for controlling the mist.
The URPOWER Ultrasonic Essential Oil Diffuser produces ultrafine mist via vibration. However, though it vibrates, it won’t make much noise. Like the previous URPOWER diffuser, this one also operates quietly, and won’t be a noisy disturbance to coworkers or family members.
Simply add up to 150 ml of water and a few drops of your favorite essential oil, and the diffuser will do the hard work for you. With its seven-color LED mood light, you can set the vibe you want wherever you may be.
Like the previous URPOWER diffuser, this one has two mist settings. The continuous mode makes the diffuser emit mist continuously, while the intermittent mode makes the diffuser emit mist for 30 seconds on and off. Additionally, when the water runs out, the diffuser shuts off automatically to save energy.
Pros and Cons
This diffuser works much like the URPOWER Second Generation Diffuser, in that it also has adjustable mist settings and lighting settings. However, it can accommodate 150 ml of water, while the second generation diffuser can accommodate only 100 ml. Depending on your needs and usage, the URPOWER Ultrasonic Diffuser might be the better choice.
One thing to take into account, however, is that the Ultrasonic Diffuser needs to be connected to an electrical outlet in order to be able to run. It’s therefore not as portable as it could be since it would need to stay near a power source.
3. ASAKUKI Premium 5-In-1 Ultrasonic Essential Oil Diffuser
A capacity of 500 ml, the ASAKUKI 5-In-1 Ultrasonic Essential Oil Diffuser is among one of the larger essential oil diffusers on this list. Not only does this diffuser have a bigger capacity, but it also offers more features than its smaller counterparts. Additionally, it can also work for up to 16 hours.
This diffuser comes with a vibrating plate that helps produce a fine mist. It can cover an area of 270 to 320 square feet, which is roughly equivalent to a small studio apartment. If the air in your bedroom, office, or living space tends to be dry, this diffuser can effectively moisten the air for a longer time than other smaller diffusers for essential oils.
You can also set a timer to make sure that you don’t leave the diffuser running for longer than you want it to. The ASAKUKI 5-In-1 Ultrasonic Diffuser has four timer settings: continuous, 1 hour, 2 hours, and 3 hours. You can also choose between two mist settings: weak and strong.
With the way the diffuser is designed, it can also work as a lamp. You can choose among seven different LED light colors, and you can also adjust the brightness to your desired level. Furthermore, you can set the light to automatically and gradually change from one color to another. You can also set the lamp to stay with one light color.
This diffuser offers a 500ml capacity, making it ideal for small studio apartments and other similarly-sized spaces. It can work for up to 16 hours and can allow you to set a timer.Check price
Pros and Cons
This diffuser offers many of the benefits of essential oil diffusers. There are a lot of adjustable features, and it also operates very quietly. It won’t bother you no matter what time during the day you use it.
One drawback to this product, however, is that the power cord plugs into the bottom of the diffuser, under the base. You’ll thus have to plug the diffuser in first before you pour the water into the tank. It would have been better if it had been designed to have the power cord plug into its side.
All in all, is this the best oil diffuser on the list? That remains to be seen. It’s a bit more expensive than the URPOWER Ultrasonic Diffuser. However, it has a much larger capacity and also has more features.
4. InnoGear Ultrasonic Cool Mist Aromatherapy Essential Oil Diffuser
These top rated essential oil diffusers come in a variety of sizes, shapes, materials, and colors. The InnoGear Ultrasonic Essential Oil Diffuser, for example, has a plastic shell with a natural wood grain exterior. It can thus be decorative as well, though it can offer far more than its looks.
Like the ASAKUKI 5-In-1 Ultrasonic Diffuser, this one has a capacity of 500 ml as well, and also has a variety of features. However, the InnoGear Ultrasonic Diffuser has a much dimmer LED lamp, which can be a pro or a con depending on how much light you want your diffuser to emit. You can also choose to leave the light off entirely while leaving the diffuser running.
This diffuser can automatically cycle through seven different colors, though you can also set it to stay fixed at one color. You can also choose between four timer settings: continuous, 1 hour, 3 hours, and 6 hours. If you compare this to the ASAKUKI 5-In-1 Ultrasonic Diffuser, the InnoGear Ultrasonic Diffuser can run for longer without leaving it on the continuous timer.
This diffuser sports a natural wood grain, but it’s not just for appearances. It also offers a 500ml capacity, 7 rotating lamp colors, and 4 timer settings.Check price
Pros and Cons
It seems that some people who have bought and used this diffuser have found that it doesn’t last very long before it breaks -- 5 months at most. However, it’s also possible that these issues may have occurred because the buyers haven’t been cleaning the diffuser regularly.
Another issue is that it does emit a low noise. Some might find this soothing because it’s not too loud, but some might not like even a low level of noise.
5. URPOWER Ultrasonic Cool Mist Essential Oil Diffuser
URPOWER might be a contender for the best essential oil diffuser manufacturer, with three different diffusers for essential oils on this list. The URPOWER Cool Mist Essential Oil Diffuser has a larger capacity than the previous two entries from the same brand, and it also has more features and capabilities.
Shaped like a flower bud, this diffuser looks good and works well. Of course, it offers more than just its looks. It has a capacity of 400 ml, as well as a LED light that can cycle through seven different colors.
Not only can you set the atmosphere by diffusing your favorite scents, but you can also do so by choosing one of the seven LED light colors for some mood lighting. You can also choose a soothing light color, such as blue, if you plan on using the diffuser as you sleep.
Keep away dry air for longer with this mid-sized diffuser. It can produce a great amount of mist for 6 to 12 hours and can work well in an area up to 225 square feet. This diffuser works well for bedrooms, living areas, offices, and more.
This diffuser produces a humid mist, sports a sleek design, and offers multiple settings for a more relaxing aromatherapy experience. It can also work in areas up to 225 square feet.Check price
Pros and Cons
There’s a chance that a pool of water may form underneath the diffuser. It can also soak the electrical cord, which can be hazardous. If you choose this diffuser, check up on it now and then to see if water is pooling under it.
It looks like not all models will have this same problem, but it’s best to keep an eye on your diffuser anyway.
6. ASAKUKI Premium Ultrasonic Essential Oil Diffuser
Even with its sleek, modern design, there’s more to the ASAKUKI Premium Ultrasonic Essential Oil Diffuser than meets the eye. It offers a variety of features, and can serve as both a humidifier and diffuser for aromatherapy. Compared to other diffusers, this one offers more features and has a larger capacity.
Perhaps the most remarkable thing about this diffuser is its capacity. It can easily accommodate up to 700 ml of water, but it’s still easy to clean despite its size. Additionally, more water means more mist and longer aromatherapy sessions.
Of course, that water will eventually run out. When this happens, the diffuser will automatically shut down to prevent overheating and to save energy. You can leave the ASAKUKI Premium Ultrasonic Diffuser running overnight or while you do various tasks during the day without ever giving it a second glance.
You can also set a timer on the diffuser. It has four different settings: continuous, 1 hour, 3 hours, and 6 hours. Add to this the seven different LED light colors you can choose from as well, and you have a large-capacity diffuser that is highly customizable while remaining easy to use.
Pros and Cons
While the ASAKUKI Premium Ultrasonic Diffuser is among the best essential oil diffusers out there, it also runs into the same pitfalls as many other diffusers. For one thing, it can also have the tendency to have water pooling underneath or around it. However, with the right precautions, this doesn’t have to be a problem.
All in all, however, the ASAKUKI Premium Ultrasonic Diffuser has a lot to offer. It has a lot of different options and can provide a thick mist for long hours.
7. Syntus Ultrasonic Essential Oil Diffuser with 7 Changeable Colored LED Lights
A compact essential oil diffuser can go a long way, as long as it’s designed and made well. The Syntus Ultrasonic Essential Oil Diffuser definitely packs a punch in a relatively smaller package. It won’t take up much space, but it can fill the air with mist, moisture, and the fragrance of your selected essential oils.
With a capacity of 150 ml, this is one of the smaller essential oil diffusers on this list. It’s therefore suitable for smaller areas, such as small bedrooms, study areas, offices, office cubicles, and more. Because it operates very quietly, it won’t be a distraction or disturbance in these small spaces.
Additionally, you can turn the diffuser on while leaving its LED light off. If you prefer, you can leave the light on and let it cycle automatically through the different available colors, or you can also set it to stay with one color of your choice.
With its sleek and compact design, the Syntus Ultrasonic Diffuser is a great addition to any space. It won’t take up too much space, and it can blend seamlessly into its environment.
Pros and Cons
The Syntus Ultrasonic Diffuser is a bargain compared to its counterparts with the same capacity. It's a strong contender for the best oil diffuser, and it definitely has a lot to offer.
However, it’s not without its issues. Reviews often mention problems with water leaking out of the diffuser itself, though the retailer is willing to replace defective items with ones that prove to be able to work properly.
Thus, issues like leaks are likely not caused by issues in the product design, but are often found in damaged products.
8. Anjou BPA-Free Cool Mist Essential Oil Diffuser
The Anjou BPA-Free Cool-Mist Essential Oil Diffuser is on the more expensive side, but it can prove to be worth every penny. It has a larger capacity and can thus run for a longer period than other diffusers for essential oils. With low noise and different time settings, you can use this diffuser at any time of the day, anywhere.
A 500 ml capacity gives a diffuser the ability to produce mist and fragrance for a long while. This diffuser, for example, can work for up to 12 hours. If the air where you live tends to get dry, the Anjou BPA-Free Cool-Mist Diffuser can help you prevent dry skin and other irritations caused by dry air.
Of course, this diffuser is also great for both short and long aromatherapy sessions. It comes with a timer with four different settings: continuous, 1 hour, 4 hours, and 8 hours. You can keep the diffuser running until it runs out of water, but you can also have more control over how much time it runs.
Additionally, the Anjou BPA-Free Cool-Mist Diffuser comes with an automatic shut-off once its water runs out. This means that you won’t have to worry about turning it off manually when it stops running. You can freely go about your day or let the diffuser run as you sleep.
Pros and Cons
The Anjou BPA-Free Cool-Mist Diffuser has a lot to offer and is highly regarded by many who have used it. However, it does have a couple of drawbacks.
One thing that you might find to be an issue with this diffuser is the price. It’s more expensive than other diffusers with the same or even bigger capacity. Additionally, it’s not built to be silent or whisper-quiet; it’s not loud by any means, but it will still emit a low yet audible hum.
Its best feature, which is perhaps worth paying extra, is that it can maintain the aroma of essential oils consistently for up to 15 hours. With other diffusers, you might have to repeatedly add more essential oil when the scent dissipates.
9. Viva Naturals Ultrasonic Aromatherapy Essential Oil Diffuser
Do you find that a 150 ml water tank is too small for a diffuser, but 500 ml or 700 ml tanks are too big? You might find a happy medium in the Viva Naturals Ultrasonic Essential Oil Diffuser, which comes with a 300 ml water tank. With its capacity and features, this diffuser can meet a variety of needs in a variety of settings and definitely belongs among the top rated essential oil diffusers.
For many people, this diffuser may be just right. It has a sleek, understated design with a wood grain exterior, which can fit right into any kind of decor. It also doesn’t take up much space, so it won’t be difficult to find a spot for it in your bedroom, office, or work cubicle.
This diffuser can produce mist until it runs out of water, but you can also choose a set time for it to run. You can choose to let it run for 1 hour, 3 hours, or 6 hours. The diffuser itself will automatically shut down, and you won’t have to worry about turning it off yourself.
If you let the diffuser run continuously, it can stay running for up to 12 hours. Furthermore, it can withstand the use of tap water, so you won’t have to use only distilled water.
This essential oil diffuser is a great purchase, and it’s already much cheaper than other diffusers with a 400 or 500 ml capacity. It’s great to use around the home, but it can also be a great gift for a friend or family member.
This oozes elegance with its rich wood grain. What makes it an easy choice of diffuser? Its mid-sized 300ml capacity and its ability to withstand tap water.Check price
Pros and Cons
Perhaps the best things about the Viva Naturals Ultrasonic Diffuser are its mid-sized capacity and its affordable price. Because of this, it is arguably one of the best essential oil diffusers on the market. However, it does have a couple of issues.
One thing that you might not like is the placement of the plug in adapter, which can be found at the bottom of the diffuser. This means that you’ll have to remember to fill the diffuser with water before you plug it in.
Users also report that the LED mood light does not turn off independently. This means that if the diffuser is running, the light will remain on as well. However, if you like having your diffuser double as a night light or a mood light, this won’t be a problem.
10. ASAKUKI Premium 5-In-1 Essential Oil Diffuser
With a 300 ml water tank, this is another mid-sized diffuser that can be great for various applications. From its interior to its exterior, the ASAKUKI Premium 5-In-1 Essential Oil Diffuser is designed to be able to help promote a soothing environment.
A lot of this diffuser’s functions are customizable to give you the exact experience you want. You can choose between two different levels of mist, and you can also choose between different mist diffusion modes. The diffuser allows you to choose between letting it run continuously until the water runs out, or setting a timer for 1 hour, 3 hours, or 6 hours.
It also comes with a LED lamp light that can display seven different colors. You can choose to let the lamp cycle through all seven of the colors, or you can set it to stay with one color for the duration of the session.
Among the benefits of essential oil diffusers, the ASAKUKI Premium 5-In-1 Diffuser can improve your sleep, prevent dry air, and enjoy a fresh and soothing atmosphere. You can turn it on while you work, make dinner, read books or magazines, and more. You can also leave it on while you sleep because it will automatically shut down when its water runs out.
Pros and Cons
The ASAKUKI Premium 5-In-1 Diffuser is a great starter diffuser, though it can also last for a long time with proper care and use. However, you might find that the water tank is a bit too shallow, and you might find it difficult to move the unit or fill it with water without spillage.
Additionally, it doesn’t run for very long on continuous mode. However, it works well when it comes to improving air quality in the area immediately surrounding it.
Essential Oil Diffuser Care and Hazard Guide
Like any other device, even the best essential oil diffusers will likely break down and stop working if not treated and maintained properly. Taking care of a diffuser is simple enough, but it needs regular cleaning. Every use leaves behind some residue, which can build up over time and affect the inner workings of the diffuser.
Here are the things you have to do to keep your diffuser clean:
- Make sure to turn off and unplug the device before you clean it.
- After each time you use your diffuser, wipe away excess moisture.
- Deep clean the diffuser once or twice a month. Fill the water tank halfway, then add some vinegar, maybe about 10 ml. Once the vinegar is in there, simply run the diffuser. This will dissolve any water residue.
- Diffuse the water-vinegar solution outdoors so your house or office won’t end up smelling like vinegar.
- Wipe down the whole diffuser with rubbing alcohol after the vinegar diffusion.
Using the Right Essential Oils
Are essential oil diffusers safe to use with any kind of essential oil? The short answer is no. Even the best oil diffuser will see some damage if you use oils that are unsafe for diffusers.
It’s important to remember to use only pure essential oils with your diffuser. If an essential oil has been mixed with other unknown oils, this might affect the way it is diffused, or it can leave a large amount of residue in the diffuser. Make sure that your essential oils are indeed pure before using them.
A simple way to check for purity is to drop a small amount of the essential oil on a piece of white paper. If there is no residue left behind on the paper after the essential oil evaporates, then the oil is pure. If there is residue, it is not pure and has probably been diluted with other agents.
It’s also important not to use corrosive or very thick essential oils with diffusers. Lemongrass, citronella, oregano, and cinnamon leaf are all known to be examples of corrosive essential oils. Make sure to do some research to see which essential oils are safe to use with diffusers.
Also, make sure to buy essential oils only from reputable sources. Aroma Foundry, for example, is an essential oil brand that guarantees purity and quality. It has a range of different essential oils you can choose from to set the stage for your next aromatherapy session.
Essential Oils, Pets, and Kids
Are essential oil diffusers safe to use in general? As with most things, these diffusers are safe to use, as long as you take the necessary precautions.
If you plan on diffusing essential oils with pets or other animals around, you might want to take the time to do some research first. Some essential oils can be very harmful to pets. For example, high concentrations of tea tree essential oil can be harmful to dogs, and diffusing the oil can cause worrying health issues in your pet.
It’s also important to make sure that the essential oils you choose are safe for small children if there are any in the vicinity. Essential oils like eucalyptus and peppermint contain a compound called phenol, which can irritate a young child’s developing respiratory tract.
To avoid these issues, make sure that you choose safe essential oils. You can also make sure that there are no pets or kids around when you diffuse essential oils if there are “unsafe” oils that you’d like to try out.
Finding the Right Diffuser
With so many diffusers for essential oils on the market today, it can be difficult to figure out which one is worth your money. After all, most of them work in much the same way, and only differ in terms of water capacity and a couple of other features. How, then, do you make the right choice?
You can always start with figuring out how much you’re willing to spend on a diffuser, and how big that diffuser’s capacity should be. Once you’ve figured out a budget and your preferred capacity, it will be easy to take it from there and narrow your choices down to find the best oil diffuser on the market.
Look through the essential oil diffusers on this list to see if a couple of them have caught your eye. You can compare them with the other items on the list to see how they stack up against each other.
