Essential oils offer an affordable means of self-care for many of us: their soothing scents unlock positive memories and help us unwind, not to mention they make our homes smell amazing. Diffusers are one of the best ways to fill your home with the relaxing scents of essential oils, and they can double as humidifiers that keep your skin from drying out during the long, cold winters. The only trouble is that there are a lot of them out there to choose from. How do you know which is the best essential oil diffuser for you?

In this article, we’ll look at ten of the most popular diffusers to help you determine which is the best option for your home.

Best Essential Oil Diffuser FAQ

1. What Is an Essential Oil Diffuser?

Essential oil diffusers are devices that release essential oils into the air. They disperse the oils’ scent throughout a room and provide a bit of extra humidity, which can help ease dry skin. All you have to do is fill a tray with water and a few drops of the essential oil of your choice, place the tray back in the diffuser, and switch it on. Then it will do its thing, spraying a fine scented mist that will relax you and humidify the room.

2. Are Essential Oil Diffusers Safe?

Diffusers are perfectly safe for adults, but experts suggest keeping diffusers out of rooms that are highly trafficked by children and pets, as high doses of diffused essential oils can be harmful to them.
If you have kids or pets, be sure to keep your diffuser in a high place where they won’t breathe the mist directly and consider setting it to intermittent sprays rather than a continuous, steady stream of spray. You should also take care to clean your diffuser regularly to reduce the buildup of grime.

3. What Kind of Diffuser Do I Want?

Knowing your needs and wants is key. Are you looking for a high-end diffuser that can double as a showcase art piece for your living room? Or are you on the hunt for a compact diffuser that can sit unnoticed on the corner of your desk in your office?

Maybe you want one that’s easy to take with you anywhere and can run off of a USB cable. Perhaps you’re new to the world of essential oils and just want to find an affordable basic option to see if you want to invest further. No matter your preference, this list will have the best essential oil diffuser for you. Just take some time to think about what you want in advance.

4. Are Essential Oil Diffusers Good for My Health?

Some experts tout the healing abilities of essential oils, but that doesn’t mean that putting a diffuser in your home absolves you of going to the doctor. They can put you in a better mood, certainly, and some studies have shown they have some health-promoting benefits, but they are not a cure-all.

The biggest benefit of essential oil aromatherapy is as a mood-booster: making your home or office smell like your favorite scents is an easy, instant way to put yourself at ease in the spaces you spend the most time in. The humidification provided by the diffusers on this list will definitely help keep your skin from drying out during dry weather, too.

5. What Does “Ultrasonic” Mean?

Many of the essential oil diffusers on the market advertise themselves as “ultrasonic.” This means that, rather than using heat to turn the oil and water in the tray to steam, they use vibration. Ultrasonic vibrations keep the compounds in the oil intact so their scents and the benefits they provide are pure and clean.

The first thing you’re likely to notice about this InnoGear diffuser is its look: it has a beautiful wood grain exterior and a light running around the middle of it to tell you when it’s on; that light can turn one of six colors or you can set it cycle through all of them. Beyond its appearances though, this is an excellent diffuser.

It has four timed output settings: one hour, three hours, six hours, and a continuous setting. It can hold 200 milliliters of water, so it’s compact but not so small that you’ll have to refill it constantly. You can set it to high or low mist, and it will automatically shut down when its water level gets too low.

  • ROTATING COLORS. Add dramatic ambiance while using your favorite essential oils with a diffuser that rotates color....
  • USES SUSTAINABLE WOOD. Crafted from fallen trees in Thailand with our contributions to reforestation.


The SpaRoom Natura is one of the best essential oil diffusers for the environmentally conscious. It’s made entirely from reclaimed wood, giving it a warm, classic look, and its colored light which changes hues keeps it modern. It’s also easy to use and uses ultrasonic technology for strong misting that can cover rooms of up to 300 square feet.

Its water capacity is a little low at just 80 milliliters, but that still gets you four hours of continuous diffusing or eight hours of intermittent diffusing. If you’re in the market for a great-looking essential oil diffuser that provides a strong mist stream and is made by a company that cares about the environment, look no further.


SpaRooms offers a limited warranty of six months on all of their essential oil diffusers.

Whereas the previous two diffusers prioritized a natural look with LED accents, this ASAKUKI diffuser does the opposite. It comes in the form of a large cube, much of which is made up of an LED that provides soft, colored illumination in seven different colors.

It’s not a design that will fit seamlessly into every room, but it can easily double as a mood lamp with the right aesthetic. It’s also huge, with a 700 milliliter tank that makes it most suitable for large rooms. It can run for up to twenty hours continuously before needing a refill or switching off automatically.

The large, square tank is also much easier to clean than some of its peers’ tanks. The tank is so large, in fact, that at a high mist setting this diffuser can double as a humidifier. If you have the space, this is among the best oil diffusers you can buy, and it helps that the ASAKUKI diffuser’s large size doesn’t translate to a large budget.


AKAKUKI has a lot of faith in this product, offering a one-year warranty on it as well as a six-month money-back guarantee.

Stadler Form Jasmine Essential Oil, Aromatherapy Dispenser Aroma Diffuser

Stadler Form Jasmine Essential Oil, Aromatherapy Dispenser Aroma...
  • POWERFUL DIFFUSER: This essential oil diffuser is powerful, easily filling a space with fragrance.
  • ULTRASONIC TECHNOLOGY: Blends water and pure essential oils (not synthetic oils) to disperse aroma.
  • CALMING FRAGRANCE: The soothing aromas of essential oils can help bring calm and relieve stress.


This small but powerful diffuser is perfect for those who want to fill up a large space with aroma but don’t want a big, bulky diffuser taking up space in their room. It’s equally at home on the corner of the desk in your office or on a bookshelf in the living room, fitting in well with today’s small, sleek tech gadgets like the Amazon Echo.

Even at only five by three inches, it can fill rooms of up to 540 square feet and run for a full 24 hours before needing a refill on its default setting, which will run it for ten minutes on and twenty minutes off. It can also run for up to eight hours continuously before needing maintenance. This is among the best essential oil diffusers for those who want all the aroma one can provide, but in a sleek low profile.


Stadler Form offers a one-year limited warranty on this and all of their products.

Vitruvi Stone Diffuser, Ceramic Ultrasonic Essential Oil Diffuser for Aromatherapy

Vitruvi Stone Diffuser, Ceramic Ultrasonic Essential Oil Diffuser for...
  • The stone ceramic diffuser cover is made out of the highest quality porcelain and doubles as a piece of décor
  • BPA free plastic internal water reservoir that holds 90ml and diffusers up to 500 sq.-ft
  • Two runtime settings: 7 hour interval (30 seconds on 30 seconds off) or 3 hour continuous


The Vitruvi Stone Diffuser is a high-end essential oil diffuser, and it’s also one of the best. Its simple design might not make it the centerpiece of a room, but its smooth ceramic exterior is elegant and the light strip along the bottom adds a great accent. It can also be turned off if you’d prefer the Vitruvi Stone Diffuser not call attention to itself.

It emits a solid stream of scent that’s never overpowering, and its 90 milliliter capacity can fill up a large room of up to 540 square feet. Because it uses ultrasonic vibrations rather than heat, it keeps its essential oils’ full integrity. It’s also easy to clean, and its plastic water tray is BPA-free.

The only discernible downside to this diffuser is how long it can run. It can go for three hours continuously or seven hours at its interval settings, which does not compare very well to some of the other diffusers on this list. Still, its elegant design and high-quality aromatherapy abilities make it one of the very best essential oil diffusers.


All of Vitruvi’s products, including this essential oil diffuser, come with a one-year warranty.

Young Living Essential Oils Aria Ultrasonic Diffuser


If the Vitruvi diffuser is high-end, this Young Living diffuser is downright luxurious. It also has a uniquely beautiful design that can make it a standout piece in any room, taking the form of a wood grain bowl with a round, bottle-like dome resting perfectly inside. As steam builds up, it fills the clear glass dome and seeps out through its top. It’s almost as pleasurable to watch as its scents are to inhale.

It has lights inside the dome to illuminate the steam and even emits soothing ambient sounds like babbling streams to add to your relaxation. The overall effect is mesmerizing all on its own, even before the aromas hit you.

It comes with a remote so you can change or turn off the sounds and light. Its 260 milliliter water tray can run for about one hour continuously or twelve intermittently and cover a room of about 430 feet. Overall, this is a uniquely beautiful and relaxing essential oil diffuser packed with unique features that put it high on the list of the best essential oil diffusers.


Young Living doesn’t reveal anything about their warranty unless you buy. We never like it when a company avoids standing clearly behind their product in a way that lets you take the warranty into consideration in your buying decision.

Everyone Aroma Therapy Ultrasonic Essential Oil Diffuser


This ultrasonic diffuser from Everyone Aroma Therapy looks like smart speaker and is designed to be easy to use, powerful, and small enough to move from room to room and place to place. It’s perfect for offices and living rooms alike, with a design that will fit in on a media shelf and a soothing light that can even double as a nightlight.

This is an especially great essential oil diffuser for travelers, as it can be powered by a USB cable. If you’re short an outlet and want some aromatherapy, just plug it into your laptop. Some users have even reported using it in their cars!

It’s incredibly simple to use too, with only two buttons: one to control the light, which can cycle colors, maintain a steady color, or be turned off, and one to change the stream from a three-hour steady stream to six hours of intermittent bursts. This might very well be the best essential oil diffuser for bargain-hunters who are looking for a product they can take with them wherever they go.


Everyone Aroma Therapy does not offer a warranty with this product, but it can be returned within two weeks of receiving it.

SpaRoom Mysto Ultrasonic Essential Oil Diffuser

SpaRoom Mysto Ultrasonic Essential Oil Diffuser and Aromatherapy...
  • UP TO 10 HOURS OF MIST. Continuous essential oil diffusion for up to 5 hours or switch to intermittent mode for 10 hours...
  • AROMATHERAPY PERFECTION. A powerful aromatherapy mister that provides a home spa experience when used with your favorite...


Simplicity is the name of the game for the SpaRoom Mysto, which has only a single button. It comes in either a marble finish or gleaming bronze, neither of which is particularly inconspicuous. On the bright side, this diffuser is small and won’t dominate a room like the Young Living Aria diffuser.

The single button allows you to cycle through the Mysto’s various mist and light settings with ease, making it a great choice for those who are busy or anyone who doesn’t want to fiddle with a ton of options. The only downside on the ease of use front is that the light, which offers varying brightnesses but only white as a color, cannot be turned off while the Mysto is in use.

This little diffuser has a surprisingly long duration. It’s able to run for up to five hours continuously or ten hours with intermittent spray. Its tray can hold up to 140 milliliters of water, and its auto-shutoff feature makes it safe for those who want to fall asleep to the soothing scents of aromatherapy.


SpaRoom offers a six month limited warranty on all of their essential oil diffusers.

  • INTELLIGENT&SAFE: Automatically turn off when the diffuser runs out of water. No worry about damaging the device itself...
  • UNIQUE AND COMPACT DESIGN: The URPOWER aroma diffuser is coated with wood grain, it can also be used to a decoration for...


The URPOWER Essential Oil Diffuser ranks among the very best values in the world of diffusers. It also happens to be one of Amazon’s top-selling essential oil diffusers, and it’s not just because of the bargain budget. Its 100 milliliter water tray can provide three to four hours of mist in a continuous stream or six hours with an intermittent stream and cover a room of up to 215 square feet. It’s not the most powerful diffuser on this list, but it’s a great pick for those looking for one for their bedroom or office.

It has seven different colors for its light and comes in a variety of colors, all of which mimic wood grain in a teardrop-like vase shape. It’s small enough to fit into any room, only about the height and width of your average iPhone, but the lights can only be dimmed, not turned off. That’s really the biggest downside for this diffuser, which is a real bargain and one of the best essential oil diffusers in its budget.


URPOWER offers a 90-day money-back guarantee if you’re unhappy with this diffuser for any reason, and one-year warranty should anything otherwise go wrong.

Homesick Ultrasonic Aroma Oil Diffuser

Homesick Ultrasonic Aroma Oil Diffuser, Black
  • Ultrasonic vibrations enhance your Homesick fragrance oil experience
  • Water tank capacity of 100ml (3. 3oz) for up to 6 hours of diffusing
  • Two operation modes - strong or standard mist


The Homesick Ultrasonic diffuser is a top-notch product that comes from a company that specializes in oils that smell like your hometown. If you want to smell the breeze through the trees in Central Park or the waves of the Pacific on Santa Monica Beach in Southern California, you’ll love their oils and this diffuser. Its 100 milliliter tank can provide up to six hours of diffusing, depending on whether you set it to strong or standard mist stream.

It has an LED light around its base that provides some soft mood lighting, but the design is otherwise a simple black vase-like shape that should fit in well with most decor. It’s more expensive than some of the options on this list, but it’s crafted from high-quality material that sets it apart from some of the more budget-friendly diffusers on this list.

Amazon also offers it packaged with some of Homesick’s essential oils, including a California bundle and a Tri-State bundle when available, so if you’re curious to try out their unique scents you can have them shipped alongside this, one of the best essential oil diffusers out there.


Homesick has a thirty-day return policy but no warranty, so if you purchase their ultrasonic aroma oil diffuser you should be sure to use it at least a handful of times within the first month to ensure it’s the right pick for you.

The Verdict

These are ten of the best essential oil diffusers out there, and it’s tough to go wrong with any one of them. Which is best for you will all depend on what you’re looking for out of a diffuser. If you want a diffuser than double as an art piece and money is no object, the Young Living Essential Oils Aria Ultrasonic Diffuser is easy to recommend thanks to its uniquely mesmerizing design and extra features like speakers, music, and ambient sounds.

If you want a diffuser that’s beautiful but is also for those on a budget, the InnoGear 200ml Aromatherapy Essential Oil Diffuser might be the right pick for you. If you travel a lot and want a compact product that can run off of USB power, the Everyone Aroma Therapy Ultrasonic Essential Oil Diffuser is a great pick.
