Best Essential Oil Diffusers

Aromatherapy has been around for centuries, offering a long list of health benefits. Today, aromatherapy is used in many households to relax and rid the home of unwanted odors caused by smoking, pet dander, cooking, and the like.

By finding the best essential oil diffuser the market currently offers, you’ll no longer need to spray room fresheners in your home, which are often not recommended for use around young children or pets.

The best essential oil diffuser immediately shows the difference. When you have one in your home, you simply walk into a pleasant smelling room and immediately feel relaxed, just like you were visiting a spa.

When you use natural essential oils in your diffuser, you reap multiple benefits. In addition to a soothing sense of relaxation, you can also experience physical benefits when you inhale the essential oil mist and when it rests on your skin.

Now that your curiosity has been piqued, it’s time to find out how you can get the best essential oil diffuser in your home.

How to Choose the Best Essential Oil Diffuser

Because aromatherapy is all the rage right now, there are plenty of essential oil diffusers in the market to choose from. But you don’t want to settle for just any diffuser—you want to get the best essential oil diffuser out there. Here are some tips to help you find it.

The type of diffuser

Different models include nebulizer, evaporative, heat and ultrasonic diffusers. Check the diffuser’s label to find out which kind it is.

The most popular type of diffuser uses ultrasonic technology, which allows it to function super quietly.

The ultrasonic model uses vibrations to diffuse the essential oil into the air around you. Unlike heat diffusers, which destroy the molecular structure of your essential oils, the ultrasonic diffuser keeps the molecular structure intact, allowing you to reap both the aromatic and therapeutic benefits of the oils.

The function of your diffuser

Some diffusers purport to have multiple functionalities. These products not only diffuse essential oils, but also humidify and even purify the air around you, improving the overall air quality. But if you’re not looking for a humidifier or air purifier, you can settle for a product that only diffuses essential oils.

Where you use your diffuser

Essential oil diffusers vary in water capacity. The bigger the water capacity, the longer it can mist and operate.

If you want to sleep with the diffuser on for the whole night through, choose a larger capacity diffuser. But if you’ll be using the product in rooms where you are only spend a couple of hours at a time, then you can opt for the smaller capacity diffusers.

What to Look for in the Best Essential Oil Diffuser

Now that you’ve definitively decided to buy a diffuser, it’s time to look at the little details that set each product apart.


Yes, design matters. You don’t want your room to smell nice, but have a tacky-looking diffuser visible for all to see. You want a diffuser that looks just as good as it performs. Of course, your budget will play a role in which model you can afford.

Light show

Some essential oil diffusers emit light, making them even more attractive. The light is especially beautiful in the dark—these diffusers can even serve as night lights. You’ll probably want to find a diffuser that has a programmable light function.

Most essential oil diffusers allow you to cycle the colors in a loop, let the color stay fixed or simply turn it off without affecting the misting option. You also want a diffuser that allows you to adjust the brightness level, especially if you prefer sleeping in a dark environment.

The design of your diffuser will play a role in how bright its light will shine.


Your essential oil diffuser distributes the scent of your essential oil by producing a mist. The best diffusers have programmable mist functions. Most essential oil diffusers can be set to intermittent misting or continuous misting.

Noise level

Because you’ll most likely be sleeping with your essential oil diffuser on, you’ll want one that generates minimal noise. If you choose an ultrasonic diffuser, that won’t be a problem.

Make sure to watch out for essential oil diffusers that have alarms that go off before the unit shuts down, which might disturb you.

Safety and security. Since there’s a good chance you’ll fall asleep or go out while the essential oil diffuser is still on, you’ll want the assurance that it has a safety feature. Most diffusers have an auto shut-off feature when the water runs dry.

InnoGear 100ml Aromatherapy Essential Oil Diffuser

Perfect for small spaces, The InnoGear® 100ml Aromatherapy Essential Oil Diffuser is compact enough to bring with you when you’re doing yoga, off to the office or just want your children to sleep soundly in their rooms.

Small but definitely effective, the InnoGear does not disappoint when it comes to delivering therapeutic benefits to you and your household.


  • 100-ml water capacity lasts up to 3 hours on continuous mist and 6 hours on intermittent mist
  • Uses ultrasonic technology
  • Whisper-quiet operation
  • Humidifies the room, perfect for preventing dry skin and lips
  • 7 different light colors to choose from
  • Auto shut-off feature for added safety


One of the best things about the InnoGear® 100ml Aromatherapy Essential Oil Diffuser is its portability. And despite its small size, not a single function was sacrificed — this diffuser works perfectly well.

Although it only carries up to 100 ml of water, the diffuser can give you up to 6 hours of aromatherapy when set to intermittent misting. This also saves your precious essential oils from depleting too quickly.

It works very quietly, so it can be placed on your bedside without disturbing you. You can let your children have fun with the changing the mood lights, or simply let it stay on one color if you want. You can even brighten or dim the light according to your preference.

And no worries about the unit burning out — it shuts off automatically when the water level runs dry.

Things to be Aware Of

The InnoGear® 100ml Aromatherapy Essential Oil Diffuser’s small size is one of its great advantages, but its size also limits the length of time you can use it for. You won’t be able to keep this unit running for the entire night.

You do have the option of letting it run for up to 6 hours, but only when it’s set to intermittent misting. At this setting, the diffuser mists for 30 seconds, then rests for 30 seconds.

Bottom Line

This is a great unit for small rooms, or if you want to take your aromatherapy along with you wherever you go. But if you’re looking for a long-lasting essential oil diffuser, the InnoGear® 100ml Aromatherapy Essential Oil Diffuser may not be the best choice for you.

The best thing about it? It’s small enough to bring with you to your office or move around from room to room at home.

It’s equipped with ultrasonic technology that helps you experience the full therapeutic benefits of your essential oils.

To top it off, this unit doesn’t make a loud sound when it’s diffusing or when the night light is on. It’s whisper-quiet when turned on, so it won’t disturb you even when you’re sleeping.

The diffuser also comes with thoughtful features such as an auto shut-off mechanism, so that the device turns off when it runs out of water. It comes with a measuring cup that makes it easy to fill the tank, and lastly, it has programmable light and misting functions.

You also get the benefits of humidified air with this small device. It can sufficiently humidify a small room so that you won’t suffer from the effects of dry air, especially during the winter season.

Things to be Aware Of

Taking off the cap or cover to fill the URPOWER 2nd Version Essential Oil Diffuser can be a little tricky at first, but it’s simple enough once you get the hang of it.

This is also a rather small device, with only a 100-ml water capacity, so it won’t last throughout the night. But if you’re diffusing a small room, this is more than enough to do the job.

Bottom Line

The URPOWER 2nd Version Essential Oil Diffuser is worth getting excited over. With more misting power than the earlier model, you can look forward to more aromatherapy benefits.

URPOWER 500ml Aromatherapy Essential Oil Diffuser

If you’ve enjoyed using the smaller URPOWER Essential Oil Diffusers, you’ll love the URPOWER 500ml Aromatherapy Essential Oil Diffuser even more. It’s not only bigger, but has more beneficial functions for you and your whole family.


  • Large, 500-ml water tank capacity
  • 5 in 1 function: essential oil diffuser, humidifier, ionizer, air purifier, night light
  • Uses advanced ultrasonic diffusing technology
  • Whisper-quiet operation
  • Works for up to 10 hours
  • Programmable misting and light functions
  • Covers larger spaces than smaller models


The URPOWER 500ml Aromatherapy Essential Oil Diffuser doesn’t disappoint. As a night light, the whole device is illuminated thanks to its opaque material. If you prefer not to sleep in the dark, the device can sufficiently light up even a large room.

It also has 500-ml water capacity, which can last you up to 10 hours. You can also choose from the misting programs depending on your aromatherapy preference.

You can even use the device without the night light, or use it purely for its lights without the misting function turned on.

In addition to using advanced ultrasonic diffusing technology for aromatherapy, the URPOWER 500ml Aromatherapy Essential Oil Diffuser can humidify a large room, which is particularly useful during the dry seasons.

It can also purify the air, letting you enjoy better air quality at home. Its ionizing technology helps capture even the smallest allergens. Gone are the days of allergy attacks with this device in your home.

Things to be Aware Of

Since this is a multi-use device, it needs to be cleaned regularly, particularly due to its air purifying function. It’s recommended to clean the device once a week, which some people might find to be too much maintenance for an aromatherapy device.

This diffuser uses ionizing technology, which is known for producing ozone. Although the ozone produced is very minimal, ozone is not recommended for patients with respiratory diseases like COPD.

Also, since the unit is quite large, it produces a bright light that may be disturbing for some people, especially if you prefer to sleep in the dark.

Bottom Line

This beast of a diffuser delivers on its promises. If you dislike how smaller diffusers don’t work throughout the night, you’ll be delighted to use the long-lasting URPOWER 500ml Aromatherapy Essential Oil Diffuser. And as an added bonus, it gives you cleaner air.

InnoGear 200ml Aromatherapy Essential Oil Diffuser, Wood Grain

Bring the spa experience to your home with the InnoGear 200ml Aromatherapy Essential Oil Diffuser, which comes in a wood grain finish.

There’s something so relaxing about a space decorated with a bamboo wood grain finish, and the InnoGear 200ml Aromatherapy Essential Oil Diffuser gives that extra aesthetic pleasure.


  • 200-ml water tank capacity
  • Programmable misting options: 1 hour, 3 hours, 6 hours and continuous
  • Programmable lighting options: 7 changing mood lights
  • Uses ultrasonic technology for whisper-quiet operation, and reliable essential oil diffusing technology
  • Auto shut-off mechanism prevents your device from burning out


One look at the InnoGear 200ml Aromatherapy Essential Oil Diffuser Wood Grain is enough to make you fall in love. And once it starts working, you’ll know that you chose the right product—it works just as beautifully as it looks.

The wood grain finish allows it to easily blend in with your home décor, instantly giving your room a spa-like look and feeling.

It’s also super easy to open and fill with water. Close the cap back on, and you’re left with a small band of light coming through the middle of the device, as well as through the misting mouth. This feature will particularly appeal to those who prefer a dimmer night light.

The light and misting buttons work separately, allowing you to operate each individually — purely as a diffuser, or purely as a night light. It’s also easy to use. You only need to press the button once or twice to select the desired function.

Finally, the diffuser features an auto shut-off mechanism, so you don’t have to worry about your house burning down while you’re sleeping with the diffuser on. It automatically shuts off when the water runs dry.

Things to be Aware Of

The unit is not chargeable, which means that it needs to be plugged in to work.  As long as you have an outlet adjacent to where you want to enjoy aromatherapy, this shouldn’t be a problem.

A 200-ml water capacity diffuser may not be enough for those who want to enjoy the benefits of aromatherapy for more hours at a time.

Bottom Line

The InnoGear 200ml Aromatherapy Essential Oil Diffuser Wood Grain is just as beautiful as it is efficient. This product is the picture of the successful marriage of design and function.

URPOWER 300ml Aroma Essential Oil Diffuser, Frosted Glass Exterior

There’s definitely something different about buying an elegantly made aromatherapy essential oil diffuser compared to buying any old ordinary one.

Why settle for something plain, when there’s an eye-catching essential oil diffuser like the URPOWER 300ml Aroma Essential Oil Diffuser, Frosted Glass Exterior out there?


  • Beautiful, frosted glass upper dome with wood-grain finish lower dome
  • 300-ml water tank capacity
  • Humidifies the air to prevent problems that come with dry climates
  • Also works as an air purifier for better air quality
  • Uses quiet ultrasonic diffusing technology
  • Beautiful play of colors through the frosted glass dome
  • Works up to 10 hours at low mist setting, and 6 hours at high mist setting


The uniqueness of the 300ml Aroma Essential Oil Diffuser Frosted Glass Exterior by URPOWER is what really sets it apart from other diffusers in the market. Why settle for an ordinary, common design when you can choose this?

Since the device is divided into two parts — the frosted glass upper dome and the wood grain finish lower dome — you get just enough light for the benefits of a night light, without making the room too bright to sleep.

Thanks to the ultrasonic diffusing technology, you enjoy quiet misting operation while reaping the full benefits of the essential oils, as their molecular structure remains intact, as opposed to diffusers that use heat.

It’s just large enough to be able to diffuse, humidify and purify a master bedroom or a large bedroom. In terms of safety, the device shuts off automatically when the water runs dry.

Things to be Aware Of

The 300ml Aroma Essential Oil Diffuser Frosted Glass Exterior by URPOWER has a unique alarm system.

The unit beeps before it shuts off. If you prefer a diffuser that doesn’t send out an alarm, then this device may not be for you. However, the beeping sound isn’t loud enough to wake you up in the middle of the night.

The unit does require regular cleaning, since it also acts as an air purifier, but cleaning is easy. However, if you don’t want to perform that much upkeep, you may want to purchase a unit without the air purifying function.

Bottom Line

The 300ml Aroma Essential Oil Diffuser Frosted Glass Exterior by URPOWER doesn’t disappoint. It has an eye-catching design, blends perfectly well in your home and works efficiently to keep your air clean and your rooms smelling fresh.
