Product image of doTerra Petal Diffuser

doTerra Petal Diffuser

DoTerra’s Petal diffuser is one of our favorites for its large capacity and ease of use. Read More

Pros

  • Large capacity
  • Easy to use

Cons

  • Doesn't output much aroma

If you're interested in learning more about aromatherapy or just making your home smell like a spa, an essential oil diffuser can come in handy. It can add joy or relaxation to your home, or just provide a pleasant scent.

However, choosing the right diffuser can be challenging.

This is why after several years of testing some of the most popular essential oil differs on the market, we think the Saje Aroma Om (available at Saje) is the best for your home. With its simple and easy-to-operate design, it’s perfect for an old hat or someone who is interested in trying one for the very first time. If you’re looking for something small, cheap, and mighty, we’d recommend the Asakuki Oil Diffuser 100ml (available at Amazon)

During our trials, we discovered the top models are simple to operate, do not overpower your home while diffusing, and that special features (such as flashy LED lights or fancy stone material) don’t always make for the perfect oil diffuser.

These are the best essential oil diffusers we tested ranked, in order.

The Saje Aroma Om aced all of our tests.

Best Overall
Saje Aroma Om
  • Material: Ceramic and cement
  • Settings: Continuous or interval
  • LED light: Yes
  • Capacity: 88ml

Our new Best Overall, the Saje Aroma Om diffuser, beat every other diffuser on this list. It is simply elegant, made of ceramic and cement with an angled spout, it provides an instant splash of lovely décor for your home. It also performed well on top of being stylish. We even got to use an essential oil made for the Om during testing that had lovely bright notes of citrus.

The Saje diffuser was whisper quiet and easy to use, clean, and store. It also comes with an LED light and automatic shut off for maximum convenience. It was quite easy to set up and produced a steady stream of delightful scent as it diffused.

The one downside is that its diffusing power may be too much for some people. It produced a very strong scent that filled the room quickly, which is surprising considering it has the smallest capacity of any diffuser that we tested. That being said, this would be useful for a larger room and may work fine for you.

Pros

  • Cool design

  • High-quality materials

  • Easy to operate

Cons

  • Nothing we could find

The Asakuki is simply the best diffuser on a budget.

Best Value
Asakuki Portable Essential Oil Diffuser (100ml)
  • Material: Polypropylene
  • Settings: Intermittent timer and automatic shut-off
  • LED light: Yes
  • Capacity: 100ml

Asakuki is a popular name in this space so we just knew we had to look for ourselves. We tested both the 100-milliliter and 500-milliliter models and the snazzy smaller model took our spot for Best Value. We loved how it creates a noticeable but not overwhelming scent during diffusing at an affordable price.

Despite having less water capacity, the smaller Asakuki diffused the citrus scent we used in testing evenly. There is beauty in simplicity and the smaller model provides a nice touch to the room with its simple white lid and wood grain bottom,and different light and mist modes.

We also liked how quiet the smaller model diffused during testing. It was little more than a whisper while it was running, compared to the occasional sputter the larger Asakuki emitted. Easy to operate and clean because of its basic plastic covering, this Asakuki is a solid choice for a first-time user who may not prefer the overpowering scent of the 500-milliliter mode.

Pros

  • Simple design

  • Quiet

  • Even diffusing

Cons

  • None that we could find


Other Essential Oil Diffusers We Tested

Product image of Kumi Stone Diffuser
Kumi Stone Diffuser
  • Material: Stone and ceramic
  • Settings: Continuous or interval
  • LED Light: No
  • Capacity: 100ml

The Kumi stone diffuser is a great little number if you’re looking for something super stylish without breaking the bank. Made with a white or black ceramic color, it is one of the more aesthetically pleasing oil diffusers that we tested.

Easy to use, clean, and store, the Kumi will fill the room with an invigorating but not too powerful scent. While there are no special features other than the stone and ceramic design, the Kumi would make a lovely addition to any home.

Setting up the Kumi was also really easy, just fill the tank with water, snap the shell on and you’re ready to go. The only drawback we can see about the Kumi is that it might be harder to clean the outer shell because of the material, but this is a small flaw considering all the pluses of using this diffuser.

Pros

  • Beautiful design

  • Strong diffusing

Cons

  • Nothing we could find

Product image of URPOWER Essential Oil Diffuser
URPOWER Essential Oil Diffuser
  • Material: Plastic
  • Settings: Continuous, intermittent, and automatic shut-off
  • LED light: Yes
  • Capacity: 100ml

The Urpower essential oil diffuser is a great diffuser if you want to scent a smaller room. The only setback is in the reservoir capacity, which is small but powerful.

On all other fronts—shape, lighting options, buttons, locking base, ease of use—it’s a great diffuser. The reservoir capacity can be a big deal, though, if you want a diffuser that will run all day. If this is true, we recommend choosing an oil diffuser with a later water capacity.

Pros

  • Lightweight

  • Works great in smaller rooms

Cons

  • Difficult to open

Product image of doTerra Petal Diffuser
doTerra Petal Diffuser
  • Material: Plastic
  • Settings: Continuous and interval mode
  • LED light: Yes
  • Capacity: 150ml

We liked doTerra’s Petal Diffuser for its large capacity and ease of use. A bright red water level marker makes it easy to keep from overfilling the unit, while mist, light, and time interval buttons on the front are clearly labeled. It is immediately obvious how to use this diffuser and adjust its settings.

The Petal’s design is not obtrusive, and the built-in light emits a soft white glow, though it doesn't give you the opportunity to change colors or use the light without the mist.

While it can’t output as much aroma as others we tested, the scent it diffused lingered as long as any of the other standard diffusers we tested.

Pros

  • Large capacity

  • Easy to use

Cons

  • Doesn't output much aroma

Product image of HoMedics Connect Ultrasonic Aroma Diffuser
HoMedics Connect Ultrasonic Aroma Diffuser
  • Material: Plastic
  • Settings: Continuous and intermittent
  • LED light: Yes
  • Capacity: 140ml

The Homedics diffuser is a solid little number. It isn’t the most attractive of any diffuser that we tested, but it would make a nice addition to your room if you’re looking for something simple. It has a color-changing nightlight and is not too noisy as it diffuses. It is easy to use and clean, all you have to do is rinse the inside with water once you’re done using it. The scent production is also very good and will easily fill a room.

A few drawbacks to note: The company suggests putting the diffuser in a baby’s nursery, but the jury is still out on whether or not diffusers are safe for children, so exercise caution.

Pros

  • Nightlight

  • Quiet diffusing

  • Easy to clean

Cons

  • May not be built to last

Product image of InnoGear Upgraded 150ml Diffuser
InnoGear Upgraded 150ml Diffuser
  • Material: Polypropylene
  • Settings: Continuous, intermittent, and automatic shut-off
  • LED light: Yes
  • Capacity: 150ml

The Innogear Upgraded 150ml just didn’t hold up against the newer models we tested, although it is still a great diffuser. The features we loved initially, such as the measuring line, built-in measuring cup, and built-in LED lights are still big pluses for us, but its diffusing power was lower than others we tested.

Despite its lower score in our third round of tests, the Innogear still has unique features that make it a good purchase. For example, the top of the Innogear locks into the base for an automatic close instead of just lifting off like most models.

The locking feature made it easier for us to take it from room to room without spilling the water and the oils inside. The LED mood lighting also rotates so you can choose the color you want easily, and the Innogear could easily function as a night light.

Pros

  • Great price point

  • Doesn't spill easily

Cons

  • Design is a little boring

Product image of Vitruvi Stone Diffuser
Vitruvi Stone Diffuser
  • Material: Ceramic
  • Settings: Continuous
  • LED light: No
  • Capacity: 100ml

The Vitruvi is a simply gorgeous diffuser, made with a high-quality stone casing that will add style to any home setting. It was beautiful to look at during testing and we would love to have it in our homes.

Despite how lovely the off-white stone looked in my bedroom, it was very slow to dry after I cleaned it and the diffuser requires more essential oil per milliliter to operate at its highest level.

The added expense of more essential oils over time, cleaning difficulties, and the high price could be a deterrent for a first-timer, but the investment could be a great option for an experienced user.

Putting the drawbacks aside, the Vitruvi is a beautiful piece of decor that will match any room and a fantastic diffuser when given enough essential oil, it is just a little more high maintenance.

Pros

  • Beautiful design

  • Even diffusing

  • Sturdy construction

Cons

  • High-maintenance

  • Requires more essential oil

Product image of Airomé Serenity Medium Diffuser
Airomé Serenity Medium Diffuser
  • Material: Glass
  • Settings: Intermittent, continual, and automatic shut-off
  • LED light: Yes
  • Capacity: 100ml

The Airomé Serenity checked most boxes during our testing. It's easy to transport, attractive, quiet, and simple to operate and clean. To get the most accurate results possible, our tests focused on running each diffuser for eight hours, while popping our heads in each hour to check on their progress.

The ultrasonic Airomé diffused a fine mist evenly into the room and continuously created a pleasant but not overpowering scent. Plus, it comes in a lot of different colors and aesthetics.

The Airomé had no special features, but this diffuser offers a simple, elegant design and even diffusing power. While not extravagant, it has a clean design, with a polished porcelain lid ringed with gold.

The Airomé did not disappoint during diffusing. It adds a simple elegance to the room and dare we say the even stream of diffused lavender made us feel a bit more relaxed during the process.

Pros

  • Portable

  • Attractive design

  • Even diffusing

Cons

  • None that we could find

Product image of SpaRoom PureMist
SpaRoom PureMist
  • Material: Plastic
  • Settings: Automatic shut-off
  • LED light: Yes
  • Capacity: 100ml

The SpaRoom PureMist is a solid diffuser for its price. Several Amazon commenters claim that it won’t run without the light being on. That would indeed be a problem, especially for those who like to run a diffuser as they sleep instead of in their living room.

But the unit we tested ran with the light on or off. The PureMist doesn’t have any bells and whistles and the design isn’t as appealing as some others we tested, but the price tag is.

Pros

  • Inexpensive

  • No bells and whistles

Cons

  • Simple design

Product image of Stadler Form Jasmine Aromatherapy Diffuser
Stadler Form Jasmine Aromatherapy Diffuser
  • Material: Plastic
  • Settings: Interval mode and continuous mode
  • LED light: No
  • Capacity: 100ml

If you’re looking for a diffuser that will blend well with modern, minimalist decor, the Stadler Form Jasmine has you covered. It comes in your choice of black or white, and if it weren’t for the barely-noticeable power and interval buttons on the front, it could be mistaken for a simple bowl. Its diffusing capabilities were about the same as the others we tested except that the mist wasn’t as dense.

While that means it took a little longer for the aroma to build up in our test room, it also means that it can run for many hours longer than other diffusers. In continuous mode, the Jasmine can run for about seven hours.

Switch it to interval mode, and it can last for 21 hours. If you’re looking for a small but steady stream of oils, you’ll like the Jasmine diffuser.

Pros

  • Minimalist design

  • Steady stream of oils

Cons

  • Takes a bit longer for aroma to build up

Product image of Organic Aromas Raindrop 2.0
Organic Aromas Raindrop 2.0
  • Material: Wood and glass
  • Settings: Timed intervals
  • LED light: Yes
  • Capacity: Unspecified by manufacturer

The Raindrop 2.0 is a waterless nebulizing diffuser, so there’s no measuring required, and there’s no messing with the water-to-oil ratio. Just fill the bottom with 10 to 20 drops of essential oil and turn it on. This diffuser filled the room with an aroma very quickly, and at full blast would be great in larger rooms and open floor plans.

The Raindrop is also very pretty. True to its name, the wood-grain base and glass bottle combine to make an elegant droplet shape that looks more like art than a diffuser. The color-changing light isn’t especially bright, and can’t be paused on any particular color, and it actually looks better without it on.

The glass bottle looks delicate yet feels very sturdy seated in the wooden base, and the bottom is covered in a rubbery material to keep it stable. Cleaning is slightly more work than with a regular diffuser, but it’s not a big deal.

A few drops of rubbing alcohol diffuse for five to 10 minutes and it’s back to being clear and spotless. In our first round of testing, we named the Organics Aroma Raindrop as our top nebulizing model, but because it’s difficult to set up, it scored poorly in our recent testing.

Pros

  • No measuring required

  • Gorgeous design

Cons

  • Cleaning takes some work

Product image of Aroma Outfitters 3D Galaxy 230ml Essential Oil Diffuser
Aroma Outfitters 3D Galaxy 230ml Essential Oil Diffuser
  • Material: Glass
  • Settings: Automatic shut-off
  • LED light: Yes
  • Capacity: 200ml

Aroma Outfitters was probably the most disappointing oil diffuser we tested and not worth all of the excitement it caused with its flashy galaxy color-changing LED light advertisement. I couldn’t wait to receive and test it, envisioning a lighted galaxy on my wall combined with a calming lavender smell.

A “Most Wished For” diffuser on Amazon, it was surprising that the Aroma Outfitters fell so flat during testing. The design was cool, but it simply wasn’t functional, as we could only smell the faintest scent during testing. While the LED lighting turns your room into a virtual galaxy, you’d be better off just purchasing a regular blacklight and skipping out on the diffusing altogether.

Pros

  • Cool design

  • Advanced LED lighting

Cons

  • Weak diffusing

  • Delicate construction

Product image of Urpower 150ml Wood Grain Essential Oil Diffuser
Urpower 150ml Wood Grain Essential Oil Diffuser
  • Material: Wood
  • Settings: Continuous and intermittent
  • LED light: Yes
  • Capacity: 250ml

The Urpower Wood Grain essential oil diffuser was a solid little number if you’re looking for something inexpensive. The dark wood is aesthetically pleasing and the diffuser is compact and cute, making it easy to store if you live in a small space. It is very quiet when it runs and has some special features like an LED light and different diffusing settings that make it stand out, but not too much. It is easy to set up and has good scent production, filling the room well.

The only reason this diffuser didn’t score higher was its flimsy construction. The Urpower seems like it would do the job, but it might not last very long. That being said, if you’re looking for something cheap and aren’t interested in longevity, this oil diffuser might be for you.

Pros

  • Different mist settings

  • Easy to store

Cons

  • Cheaply made

Product image of SpaRoom Seascape
SpaRoom Seascape
  • Material: Glass and plastic
  • Settings: Continuous mist and auto shutoff
  • LED light: No
  • Capacity: 150ml

The SpaRoom Seascape Essential Oil Diffuser was a personal favorite of mine, and one of the prettiest diffusers we tested. Its glass overlay was relaxing and reminiscent of gentle waves upon a shore. You have the option to light up this diffuser, creating a beautiful seascape. While its diffusing power was decent, there were drawbacks to this product that made us pause before buying it.

While its glass design is pretty, it also makes the diffuser delicate and not very portable, as it would be easy to break. The material it’s made of also makes it harder to clean. The Seascape might make a beautiful addition to your room, but beware of its fragility if you choose to buy it.

Pros

  • Beautiful design

  • Strong diffusing power

Cons

  • Fragile

  • Harder to clean

How We Tested Essential Oil Diffusers

One important testing factor was how easy each diffuser was to operate and clean.

The Testers

Hi, I’m Cailey Lindberg, the Updates Staff Writer here at Reviewed and a full-time dog mom to a basset hound named Sandor. Scented candles, sage, and incense are basically a religious experience for me, so I wanted to see how essential oil diffusers stacked up.

Our initial round of testing was done by Reviewed’s accessibility editor, Sarah Kovac, who has used essential oils for aromatherapy and skin care off and on for years. In addition to testing products, she's covered a broad range of topics—from neuroscience to parenting to disability issues.

The Tests

To find which products to recommend, we looked for ease of assembly, use, and cleaning, as well as strength of diffusion, portability, mist output, aesthetics, noise level, special features, and overall experience.

For testing, we used an upstairs bedroom and chose a cheerful blend. Each diffuser was shut in the bedroom and turned on to continuous mist (except the nebulizers, which only operate intermittently). We popped our heads into the room at scheduled intervals to check the aroma’s strength.

How to Choose the Best Essential Oil Diffuser for You

When deciding which product to buy, it is important to know the difference between the four different types available. Each offers unique features and has pros and cons that can be weighed before purchasing.

  • Nebulizing diffusers work by using a pressurized airstream and jet nozzle, which diffuses the oil into smaller amounts that can be beneficial for aromatherapy when you inhale them. They use no heat or hot water when diffusing, but they are also the noisiest (and cost the most) of all of the oil diffuser types.

  • Ultrasonic essential oil diffusers work by using a small underwater disk to break up the essential oils so that they can be evenly diffused into the air. They’re also quiet, use no heat, and can act as a humidifier during ultrasonic diffusion.

  • Heat essential oil diffusers act by using a heated plate to diffuse the essential oils into the air, using water mixed with heat at low levels. These models are an economical and silent alternative.

  • Evaporative essential oil diffusers release the oil in segments, relying on airflow to push the scent into the room quickly. They hit the mark for speed, but the essential oil can often become diluted because it is diffused in segments.

We tested different kinds of diffusers to see which ones reigned supreme.

How To Use An Oil Diffuser

The best place for an oil diffuser is in the center of the room so that the oils are evenly distributed. Place it on a flat surface and plug it into a nearby power outlet. The type of casings varies between different designs, but generally, the top will need to be lifted off in order to fill it with water.

Use room temperature water when filling your diffuser and only fill it to the line marker. Most diffusers use 3 to 10 drops of essential oil per use, but you can consult manufacturer information for more specific instructions. After filling the water tank with the correct amount of essential oil, simply replace the lid and flip the switch to begin diffusing.

Are Essential Oil Diffusers Safe To Use?

There have been few scientific studies on essential oils and the industry has not been regulated by the FDA. David Stukus, a pediatrician and associate professor of pediatrics at Nationwide Children’s Hospital in Columbus, Ohio told the New York Times that oil diffusing may be most concerning for children with underlying conditions such as asthma and allergies, saying that that essential oils are “really good at infiltrating the upper and lower airways, which can cause irritation, especially in people with underlying chronic medical conditions such as asthma or allergies.”

Are Oil Diffusers Safe For Pets?

Oil diffusers may also be harmful to your pets. ASPCA lists the issue as complicated and recommends caution if you plan to use essential oils around your pets.

The oils are thought to be the most dangerous in their most concentrated form before diffusing and your pet could suffer if the concentrated oil is ingested or gets directly on their skin. Cats are reported to be more sensitive than dogs and the risks associated with diffusing around them can be more serious.

If you decide to use an oil diffuser with pets in your house, taking which scents you use into account is important to keep your dog or cat safe. It's worth doing some research on which scents can be toxic to pets as well before diffusing. For this guide, pets were kept out of the room we tested in, which is probably the best approach to keeping your best friend safe and healthy.
