Top 10 Best Oil Diffusers in 2024


Essential oils are all-natural and they smell wonderful – and that makes them one of the best ways to keep your home smelling clean and fresh without the use of dangerous chemicals. Spray air fresheners might contain things that you’d rather not exposure your kids or pets too, but an oil diffuser is the perfect way to lightly scent your home.

Of course, there are a lot of oil diffusers available and some work better than others. For that reason, we’ve taken the time to look at what’s available and try them out so that you can eliminate the guess work and choose the oil diffuser that’s best for you.

Before we reveal our picks, let’s talk about some of the major considerations to keep in mind as you shop.

What to Look for in an Oil Diffuser

The primary goal of an oil diffuser is to break down the essential oils used into a fine mist so that you and the other people in your home can reap the health benefits associated with them. Some diffusers run on electricity and some run on batteries. Some include extras like LED lights to add a soothing visual element to the mix.

It may help to know about the two most common types of diffusers available and how they differ from one another.

  • Nebulizing diffusers are powerful and they do not require water or heat to work. To use them, you can simply attach a bottle of essential oil and let it do its thing. The primary downside of nebulizing diffusers is that they aren’t as quiet as some of the other options. They also go through oil quickly since they diffuse pure oil.
  • Ultrasonic diffusers mix essential oils with water to create a fine mist. That means that they use less oil than nebulizing diffusers. They can double as humidifiers, and that makes them a great option for people who have respiratory problems. They tend to be less expensive than nebulizing diffusers.

It’s important to note that you cannot use citrus oils with ultrasonic diffusers because they can damage the machine. Ultrasonic diffusers must also be cleaned regularly. However, there are good options available in both types.

Some of the other things you may want to consider include:

  • Does the diffuser have a timer? In some cases, you may want to be able to control the amount of oil released.
  • Does the diffuser have a light? Diffusers with lights that can be turned off may be best if you want to use them while sleeping.
  • What sorts of oil can be used with the diffuser – and do you have to buy oil according to the manufacturer’s specifications?
  • Are there any extras included with the diffuser? Some come with starter oil kits and other goodies.
  • What is your budget? Some diffusers are more expensive than others.

Best Oil Diffusers in 2024

Now that you know which options are available and what to look for, let’s reveal our picks for the top 10 best oil diffusers.

10. BellaSentials Essential Oil Diffuser

No products found.

The first pick on our list is the BellaSentials Essential Oil Diffuser. This is an ultrasonic diffuser, so you can use it to humidify your home as well as the soothing aromas of essential oils. The dark walnut finish looks right at home with the most sophisticated décor. This unit has an LED display with seven soothing colors, and you can freeze it on your favorite color if you prefer.

There are two potential downsides to this product. The first is that while it has a very sleek look, it’s a bit difficult to open. People who don’t have long nails may need to use something to pry it open to replace the oil. The other issue is that the motor could be quieter. It’s not noisy, exactly, but it’s certainly not the quietest option available.

9. Art Naturals Essential Oil Diffuser 100ml & Top 8 Essential Oil Set

Art Naturals Essential Oil Diffuser and Top 8 Essential Oil Set

Our #9 pick is the Art Naturals Essential Oil Diffuser. We like this set because it comes with 8 essential oils included: Peppermint, Tee Tree, Rosemary, Orange, Lemongrass, Lavender, Eucalyptus, and Frankincense. The design is attractive and soothing to look at it, and the soft LED light display is calming as well. This is an ultrasonic diffuser, so it does use water.

If we could change something about this product, it would be the lights. While they’re very pretty, they also make it hard to use at night, especially for people who need total darkness to get to sleep. The other issue is that the oils included are really not kid-friendly for the most part – things like eucalyptus and frankincense are contra-indicated for use around small children.

8. Syntus 150ml Essential Oil Diffuser Portable Ultrasonic Aromatherapy Diffusers

Syntus 150ML Essential Oil Diffuser Ultrasonic Aromatherapy Diffusers with Adjustable Mist Mode and Waterless Auto Shut-Off for Home Office

Coming in at #8 on our list is the Syntus Essential Oil Diffuser. This is a very affordable diffuser with some nice features. For example, it holds 150 milliliters of water so you can run it all day or all night. It turns off automatically when the water runs out. It has two modes of use, continuous and intermittent. It runs very quietly. The 7-color LED display may be turned off for overnight use.

There are a few potential downsides to consider. First, this is an ultrasonic diffuser so you should be cautious using citrus oils with it as they may damage the machine. This is a small unit and it may not give as strong a scent as some of the other diffusers on our list. It is also worth noting that the small power light is very bright, and if you want to use it in the bedroom you may want to cover it with a piece of tape.

7. URPOWER Essential Oil Diffuser

URPOWER Essential Oil Diffuser, 150ml Wood Grain Ultrasonic Aromatherapy Oil Diffuser with Adjustable Mist Mode Waterless Auto Shut-off Humidifier and Diffusers for Essential Oils

The #7 pick on our list is the URPOWER Essential Oil Diffuser. This is another ultrasonic diffuser, and we like it for its sleek yet classic design. The LED light display is soothing, and the machine has both an intermittent and a continuous mode. When filled with water, you can expect to get about six hours of continuous use before it shuts off automatically.

The one thing we think could be better on this machine is the lid. It doesn’t attach securely – and if you have small children or pets in the house there’s a chance you could wind up with a puddle of water and essential oil on the floor. We recommend it keeping it out of reach. It’s also important to note that the LED display doesn’t turn off, making this unit less than ideal for bedtime use.

6. Raindrop 2.0 Nebulizing Essential Oil Diffuser for Aromatherapy

Raindrop 2.0 Nebulizing Diffuser for Essential Oil Aromatherapy Light-Colored Wood Base

Coming in at #6 on our list is the Raindrop 2.0 Nebulizing Essential Oil Diffuser for Aromatherapy. We like this diffuser because we love its elegant design. It’s made of plantation hardwood and hand-blown glass. Because it’s a nebulizer, it delivers a concentrated dose of essential oil for about two hours before automatically turning off. The LED light display can be turned off with the swipe of a finger, and the motor is quiet enough to be used by sleeping. It comes with a free sample of essential oil.

If we had a complaint about this diffuser, it would be that the price is high compared to the ultrasonic diffusers. However, we think that people who really want to smell the essential oils they use will appreciate this diffuser’s power.

5. Your Spirit Space 300ml Blue Marble Aromatherapy Essential Oil Diffuser

Your Spirit Space 300ml Aromatherapy Essential Oil Diffuser Portable Ultrasonic Cool Mist Humidifier - 7 Color LED Lights Auto Shut-Off Home Bedroom Baby/Room - Blue Marble

Our #5 pick is the Your Spirit Space 300ml Blue Marble Aromatherapy Essential Oil Diffuser. This diffuser has a different look from many of the others on our list thank to the marble finish. The 300 milliliter water compartment will diffuse scented mist for up to 12 hours. It has two intensities so you can control how much mist is released. The LED light display is soothing and attractive.

Our primary issue with this diffuser is the noise it makes when it automatically shuts off. It’s disturbingly loud and may even wake you up if you use it in the bedroom. However, if you fill it right before bed, it won’t wake you up unless you sleep longer than 12 hours. We also wish that the LED lights could be turned off.

4. VicTsing 300ml Aroma Essential Oil Diffuser

No products found.

The #4 pick on our list is the VicTsing 300ml Aroma Essential Oil Diffuser. We like this unit for its efficiency and its design. It runs quietly and efficiently, and it has four timing modes you can choose from to determine how long you want it to run – and an automatic shut-off feature. The LED lights can be set to stay on one color or switch, and you can also choose between a bright and dim display.

In terms of negatives, we really wish that it was possible to turn of the LED lights. While the display isn’t obtrusive, some people need a dark room at night. The lid on this is also a little loose which makes it tricky to move without it leaking at least a little bit. It does beep when it turns off automatically, too.

3. Nebulizing Diffuser for Essential Oils and Aromatherapy

Nebulizing Diffuser - Sage Core Series for Essential Oils and Aromatherapy with Gift Box (Core No Light, Ascend)

Our #3 pick is both a nebulizing diffuser and a work of art. The solid wood base and blown-glass diffuser combine for a graceful effect. This nebulizer has a timer that you can set to control the amount of oil it releases, and it can run as long as three hours without being refilled. It’s made of all-natural materials and it’s powerful enough to diffuse aromas over 900 square feet.

What we’d like to change about this nebulizer is the noise it makes when it’s running. The base vibrates slightly and if you’re sensitive to noises it may bother you. Like most nebulizers, it’s expensive compared to the ultrasonic oil diffusers. It’s also worth noting that this machine doesn’t have a light display, which may be a deal breaker for some people.

2. PECHAM 400ml Aromatherapy Essential Oil Diffuser

PECHAM 700ml Professional Water Dental Flosser for Home & Travel - Leak-Proof Electric Quiet Design Oral Irrigator -7 Interchangeable Nozzles

Coming in at #2 on our list is the PECHAM 400ml Aromatherapy Essential Oil Diffuser. We chose it because it’s a long-lasting, quiet diffuser that has just about everything you could want. The water reservoir holds 400 milliliters, more than most other diffusers on the market, and it can run for up to 10 hours continuously. It has a 7-color LED light display that gives you multiple options. You can choose one color, rotating colors, or turn the lights off completely. The wood exterior gives this diffuser a sleek look that looks great with any décor.

There isn’t much we don’t like about this diffuser. If we could change one thing, it would be the vibration plate, which does need to be cleaned periodically. However, that’s a minor quibble for a product that is really great overall.

1. NexGadget 400ml BPA Free Ultrasonic Wood Grain Aromatherapy Essential Oil Diffuser

NexGadget 400ml BPA Free Ultrasonic Aromatherapy Essential Oil Diffuser - Cool Mist Humidifier for Home,Office,Spa&More - Wood Grain-Wintech-US is The only Designated Authentic NexGadget Seller

Finally, our #1 pick is the NexGadget 400ml BPA Free Ultrasonic Wood Grain Aromatherapy Essential Oil Diffuser. We made this our top choice for a variety of reasons. First, there’s diffuser itself, which runs quietly enough to be used in a baby’s bedroom. It holds 400 milliliters of water and features four timed modes. The LED light display features seven colors with options to choose a steady color, rotate the colors, and choose between a bright and dim display – or to use no lights at all. This machine can be used as a humidifier, a diffuser, an ionizer, or just a night light. And finally, there’s the elegant tulip design. This is a gorgeous diffuser.

We really love just about everything about this diffuser. The one very minor issue you need to be aware of is that it is very important to clean it every few days by wiping it out with a cloth. Other than that, this is pretty close to perfect!


The diffuser you choose should be reliable, efficient, and soothing. Since it will be on display in your home, it also helps if it looks beautiful. The 10 diffusers on our list all fit the bill.

  1. 10. Calily Ultrasonic Essential Oil Diffuser

    Calily ultrasonic oil diffuser is one of the more affordable models due to obvious reasons. It is fairly simple with a candle-like shape and a plastic body. By no means it looks poorly made but there are models that seem a bit more fancy.

    The model works on batteries and uses a new ultrasonic system that does not generate heat. It emits a discrete mist that spreads the oil into the room. In terms of capacity the model can hold about 100 ml of fragranced oil while the batteries offer a continuous runtime of about 4 hours.

    9. QUOOZ Lull Ultrasonic Aromatherapy Essential Oil Diffuser

    The QUOOZ Lull ultrasonic oil diffuser is one of the more expensive models. Maybe a bit more expensive than it is really worth but nonetheless it is still a great option for the ones that seek to create a welcoming atmosphere. It is small, compact and looks quite well from a design perspective. It is made to look like a small lamp.

    It does not run on batteries which for some might seem like an advantage but it does limit its mobility and it can be difficult to move it around from one corner of the room to another. It has a capacity of about 200 ml of oil which is enough to up to 10 hours of continuous usage. The model includes a safety auto shut-off system that detects when the diffuser is low on oil.

    8. BellaSentials Aromatheraphy Oil Diffuser

    There are very few other oil diffusers that look as good as the BellaSential. It has a wooden texture that makes it look more like a stylish decorative element with rounded edges and a bright blue neon light. The model looks extremely well and it is fairly affordable.

    The model has a large capacity that offers it about 8 hours of usage or 12 depending on the mode selected. When it runs out of oil the model will shut down on its own to save batteries. The LED lights can be changed as there are 7 available or the diffuser can alternate between them.

    7. Calily Eternity Ultrasonic Essential Oil Diffuser

    The Calily Eternity oil diffuser is an amazing little device. It is even more impressive when looking at the price. It is well built with metal elements and a bright neon light that provides a soothing experience.

    Its only downside is the fact that it has a 90 ml capacity which should last for about 3 hours. The model runs on batteries and in order to save power it features an auto shut-off system that prevents it from running without any oil. Like most other models it has a quiet operation mode and does not require any maintenance except for the oil refill and the eventual battery swap.

    6. ZAQ Dew Essential Oil Diffuser

    ZAQ Dew Essential oil diffuser is a great option for the ones that need to add a bit of personality to a room for a special occasion. It is not the most affordable model but it has plenty to offer as it is well built and comes with a modern design that makes it work as a decorative element in any room.

    The model is available in a white glossy finish with a glowing top and glowing button. It has a 80 ml capacity which is enough to run for four hours and it is energy efficient. Like all the previous models listed it has a safety system that detects when the oil is low and turns off the diffuser until it is refilled.

    5. PureSpa Essential Oil Diffuser

    The PureSpa essential oil diffuser is one of the more basic models. It looks like a small lamp with four colors to choose from and a pleasant design. It can be used in any environment as long as the room is no larger than 250 feet in order to provide a decent coverage.

    Its diffuser system uses an ultrasonic system that helps heat up the oil and spread it into the room. This means that it is quiet and it does not get hot. When filled with oil the large capacity recipient makes it run for about 7 hours continuously which is quite decent when compared with similar models from the same price range.

    4. InnoGear Aromatherapy Essential Oil Diffuser

    The InnoGear essential oil diffuser is one of the most popular models available. Rated as a best seller the model is not only affordable but also quite efficient. It might not have the most appealing design but it is an excellent choice for the ones with a limited budget.

    The model has two control buttons that control the humidity and the light. Using ultrasonic technology the model does not heat up and does not generate any kind of noise. The oil is diffused in a controlled manner and when the level gets low the diffuser shuts-off automatically. It features two operations modes which gives it a runtime of about 6 hours.

    3. Deneve Essential Oil Diffuser

    Deneve’s essential oil diffuser is one of the smallest models in our pick list. Designed to look like a rock the model is both elegant and easy to use. Its design is modern while its price tag places it in the more affordable range. The build quality and attention to detail does make it a great decorative object but there are better models out there.

    Its capacity is fairly modest but it is a highly efficient model with a runtime of about 5 hours until it gets empty. Using ultrasonic technology the model does not heat up and it is completely silent when running.

    2. Now Foods Ultrasonic Wood Grain Oil Diffuser

    The Now Foods oil diffuser is a gorgeous device. Almost its entire body is covered with a wood-like texture that gives a more distinct and pleasant look. Very few other models can even be compared to it.

    It uses an ultrasonic diffuser that does not generate heat and does not affect the properties or scent of the oil. This also makes it extremely quiet and high efficient. It runs an average of 8 hours before running out of oil when it will shut-off automatically. One of the more important features is the fact that it runs on batteries and can be charged. This means that the model is easy to more around the room without having to worry about a power source.

    1. Urpower Essential Oil Diffuser

    The Urpower essential oil diffuser is one of the best models to get. Its design with the wooden body and discreet lights gives it finesse and turns it into a great decorative object. The buttons are barely noticeable while the top offers a bit of illumination.

    The model works as an ultrasonic diffuser with almost no heat generated and zero noise. Its biggest asset is the fact that it has a 300 ml capacity that can last up to 10 hours. It is one of the few models in our pick list that last this long. Unlike other models it does not run on batteries which eliminates the worry to change then or having the device stop working due to low power.
