What Is a Diffuser Humidifier?

A diffuser humidifier is a combo between a humidifier and an essential oil diffuser. They work by combining a cool mist with your chosen essential oil. Consequently, they raise your humidity levels slightly and spread a fresh scent.

However, despite having a humidifying feature, these devices aren’t generally as effective as an actual humidifier. Thankfully, you can also find effective humidifiers with an essential oil option — if that’s your jam.

Diffusers are also commonly used to provide aromatherapy by diffusing essential oils into the air. Different scents and plants can make you feel different things. For example, lavender reduces stress and peppermint improves headaches.

Scented candles are another way to achieve some kind of aromatherapy. However, diffusers are more effective.

How Can It Benefit Me?

Humidity plays an important role in our environment and personal comfort. High humidity can cause dampness, clamminess, mold and health issues. On the other hand, very low humidity can cause dry skin, irritated mucous membranes and even increase the risk of viral infections (1).

It’s crucial to create a well-balanced home environment for you and your family’s health. If you live in a dry area or experience drier climates as winter approaches, a humidifier would be beneficial. A humidifier will put some of the lost moisture back into the air you breathe — easing your chapped skin and lips.

Many homeowners who suffer in dry climates often prefer to keep a humidifier running during the night. This can help to reduce snoring, stuffiness and even nosebleeds.

The added feature of an essential oil diffuser is only a bonus. Not only do you get to enjoy the lovely scent, but you can also benefit from their abilities.

Are There Any Risks of Using a Diffuser Humidifier?

Although a diffuser is a helpful device when it comes to spreading essential oils, there’s one thing to keep in mind. If you have pets, you might want to reconsider which oils you’re using.

According to the ASPCA, cats are especially sensitive to a variety of essential oils. It can affect them in numerous ways, including gastrointestinal issues, liver damage and even depression (2). Merely inhaling essential oils could cause aspiration pneumonia (3).

Experts thus advise that you should keep diffusers away from your pets. If you do want to use a diffuser, do so in an area where your pets don’t have access.

Finding the Best Diffuser Humidifier

There’s no doubt that diffuser humidifier combos are beneficial to our physical and mental health, but which is the best? That’s a personal question, since there are so many different diffusers available on the market. By knowing what you need to look for, you can quickly find the best diffuser humidifier for you.

Tank Capacity

As with any humidifier, tank capacity plays an important role. In short, the size of the tank will determine how long the humidifier can run before needing a refill.

However, diffuser humidifier combos generally have quite small tanks because they aren’t meant to humidify as effectively. On average, most combo tanks are around 20 ounces, with some being as little as 16 and others as large as a gallon.

Do You Have Room?

A larger tank will result in a larger device. Plan where it will stand to ensure it will fit.

When choosing a device, consider its tank size — most brands will give you an estimated running hour in different settings. For instance, if you’d like your humidifier to run throughout the night, choose a unit with a suitable tank size. On the other hand, if you need a device to improve the office environment, a smaller tank will suffice.


There are a few features we find essential for these types of devices to improve user-friendliness and convenience. Here are some helpful ones:

  • Auto-shutoff: If you want your humidifier to run through the night, this feature is essential. The auto-shutoff will automatically turn the device off a few seconds after the tank empties. As a result, it saves your humidifier from burning out and causing damage.
  • Timer: A timer enables you to conveniently set your preferred hours to run a humidifier. This feature is also excellent for night use since you can set it to turn off after a certain number of hours.
  • Sleep mode: If you like your beauty-sleep to be dark and undisturbed, sleep mode is essential. When in sleep mode, most devices will work on the lowest setting with or without dimmed lights.


Although most diffuser humidifiers are made of some form of plastic, the type is important. We highly recommend that you choose products that are BPA-free and preferably FDA-approved as well.

Essential oils are very potent and can leach plastic if exposed for long periods. However, as the mist and essential oils are dispersed in the air, so are any leached chemicals.

Take Note

Although there isn’t any scientific backing that BPA plastic diffusers are harmful, we like to avoid it when possible.

The Best Diffuser Humidifiers of 2022

As we searched for diffuser humidifiers, our goal was to find devices that were effective at diffusing oils as well as humidifying. We paid close attention to the materials to ensure your safety as well as your family’s. Here are the best diffuser humidifiers:

1. Asakuki Aromatherapy Humidifier Oil Diffuser

Best Overall Diffuser Humidifier

If you’re looking to create a zen-vibe in your home, this diffuser humidifier is for you. The Asakuki is the perfect addition to any space in need of some aromatherapy. It works very effectively and efficiently, creating a long-lasting fragrance with a single fill.

In addition, the humidifier function creates a cool mist that will increase humidity without dampness. The device also has a few smart features such as a timer.

The Pros

Single Fill Long-Lasting

With most diffusers, you’ll have to refill with essential oils constantly to maintain the desired scent. However, with the Asakuki diffuser, you’ll only need to fill it once with your favorite essential oil. The device claims to keep a lasting scent for 16 hours on low mode.

This enables you to sit back and enjoy your favorite aromas without needing to refill all the time. Consequently, it saves you time and effort.

Smart App

Asakuki had adopted the convenience of technology as this can be controlled using their Asakuki diffuser app and can be synced with Alexa. Moreover, you can adjust how concentrated you want your diffuser to be.

Timer Settings

As a convenience, you can set a timer to suit your needs. The diffuser humidifier will automatically turn off when time is up.

The Cons

Doesn’t Work with Google Assistant

I love how it gives me the liberty to choose from whatever essential oil I like to pair it with and how I can use voice commands. However, I find it a bit tricky to setup using the app, aside from that it is incompatible with Google Assistant. This can be very inconvenient and slightly frustrating but it is manageable.

2. Urpower Aromatherapy Oil Diffuser Humidifier

Best-Looking Diffuser Humidifier

If you’re looking for something more unique, the Urpower diffuser is right up your alley. It has a very unique square design that looks appealing in any setting. This model also features color-changing LED lights, so you can choose your preferred color.

The humidifier can run for a long time, thanks to the large tank capacity of 24 ounces. It does, however, tend to create condensation underneath the lid. All in all, this is an awesome diffuser loved by many customers.

The Pros

Unique Design

The first thing you’ll notice with this diffuser humidifier is the design. It has a modern cube design that will look unique and attractive in any room. In addition, the wooden base really adds to the zen vibe diffusers create.

The squared shape doesn’t only look attractive, but you can also change the LED light to your favorite color. Choose between seven colors to create chromotherapy along with your aromatherapy.

Large Capacity

Because of the design, this humidifier can hold up to 24 ounces of water. This enables it to go for longer without the need to be refilled. In fact, it can run for 20 hours straight on the low setting and more than 10 hours on high. Finally, once the tank empties, the device will automatically turn off to prevent damage.


We love the timer feature since it enables you to use the diffuser humidifier at night without worrying about shutting it off. Set the timer to one, three or six hours depending on your preferences.

The Cons

Creates Condensation in the Lid

Because of the humidifying feature, the diffuser produces a significant amount of condensation underneath the lid. This can cause a few leaks as you’re removing the lid.

Additional Specs

Working Hours on Low Setting 20 hours
Working Hours on High Setting 10 hours
Tank Capacity 24 ounces
Dimensions 6.5 by 6.3 by 5.7 inches
Weight 1.8 pounds

3. Earnest Living White Ceramic Diffuser Humidifier

Best Small Diffuser Humidifier

For smaller rooms and areas, we highly recommend the Earnest Living diffuser humidifier. It has a compact design with seven color-changing options to set the mood in the room.

Despite the small size, it has great power and is equipped with a high-performance ultrasonic plate. The plate creates a cool mist infused with your favorite essential oils. As a result, you get a thick, powerful vapor to enjoy — and show off when guests are over.

The Pros


This diffuser is an excellent addition to any small bedroom or area of the house. It has a very compact design that enables you to place it on a shelf or small coffee table. It’s easy to carry to where you might need it and looks stylish in any setting.

Minimalist Design

I personally love its uniquely crafted minimalist design that will suit as room decor. Unlike most of the diffuser humidifier that’s made of plastic, this one is made of ceramic material. If you would prefer a different design aside from this one, you still have five options left as the company had made several designs to match your home artistry.


If a humidifier runs out of water, it can be damaged or burn out. However, to prevent this, Earnest Living has equipped its diffuser with an auto-shutoff feature. Whenever the reservoir is low in water supply, it turns off automatically.


As a fun feature, you can choose between seven different bright colors to brighten the day. You can easily set a romantic mood or a dim light for movie night. In addition, it can be used as a night light if desired.


This can serve either as an oil diffuser, a night light, a humidifier, or even as home décor. You see, it comes with different uses and can be easily given as a get-well gift.

The Cons

Prone to Breakage

When not handled with extra care, this item is prone to breakage as it is made of ceramic material, that, as we all know it, is brittle.

Additional Specs

Working Hours on Low Setting 3 hours
Working Hours on High Setting 0.5 to 2 hours
Tank Capacity 3.38 ounces
Dimensions 4 by 4 by 7 inches
Weight 1.5 lbs

4. Pure Daily Care Ultrasonic Diffuser

Best Bohemia Diffuser Humidifier

Pure Daily Care is one of the prettier diffusers on the market. It has an earthy design with subtle color-changing mood lights that suit any type of home. Furthermore, it creates a strong mist of cool moisture and essential oils that can work for a long time on the low setting.

You can set the timer to suit your needs or set it to either high mist or low mist. It also includes ten pure essential plant oils.

The Pros

Complete Bundle

This bundle is a complete all-in-one package that not only includes the diffuser but also includes ten essential oils that are therapeutic in nature.

Timer and Auto-Shutoff

You can set the timer to one, three or six hours of continuous use. It’s such a handy feature if you like to keep the humidifier running as you fall asleep. In addition, to avoid any damage to the diffuser, the device will automatically turn off when the reservoir runs low.

Color Options

You get to choose between seven soothing colors settings to suit your mood. As well as the seven colors, you can choose between bright and dim settings for each color — excellent for night or day.

The Cons

Covers A Small Room

The humidifier can cover between 107 and 140 square feet at a time. It’s an excellent option for a bedroom or even a yoga studio. Moreover, the earthy design gives it a peaceful look, as if it was a little flower emitting essential oil mists. Should you want bigger area coverage, you may want to check Urpower.

5. Urpower Essential Oil Diffuser Cool Mist Humidifier

Best Design Options

Urpower 2nd version diffuser is a favorite among many customers and it’s easy to see why. It works like a dream when it comes to spreading essential oils along with a cool mist to help soothe your chapped skin.

This device is very user-friendly, as it comes with two options: intermittent mist and continuous mist. When in continuous mode, it will mist continuously for three hours at a time. However, in intermittent mode, it will mist on and off at 30-second intervals for up to six hours.

The Pros

High-Quality Materials

To ensure safety for you and your family, Urpower uses a very high-quality plastic that’s free of harmful chemicals.


The entire device lights up in bright LED lights and you get to choose between seven bright colors. These can be set at dim or bright, depending on your preferences. On the other hand, if you don’t like the amount of light this device creates, there are other options.

You can choose between a yellow wooden design, dark wood and grey and white design. Note, though, that these won’t light up similarly to the white design. They only feature a small LED light at the top of the device.

Helps You to Relax

When the weather gets dry, we’re left dealing with chapped lips, skin and even dry sinuses. This can be very uncomfortable. But with the help of this diffuser humidifier, you can enjoy a more comfortable environment without the risk of dampness.

The Cons

Smooth Texture

Although the material is high-quality, it can be rather slippery as you’re trying to move it around due to the smooth texture. We’d like it to have more texture to allow a better grasp.

Additional Specs

Working Hours on High Setting 3 hours

6. Raydrop KC-RD05 2.5L Cool Mist Humidifier & Essential Oil Diffuser

Easiest to Fill

If you’re looking for a humidifier that will last a long time, this is your guy. This is equipped with an extremely large tank that provides you with up to 30 hours of humidification. Furthermore, you can add a few drops of your favorite essential oils in the water tank and they’ll be emitted into the air.

This unit is very user-friendly and easy to fill by removing the lid at the top. In addition, it features an auto-shutoff when the tank is empty.

The Pros

Effective Humidifier

Unlike the previous models on our list, this little device is actually a humidifier. It’s designed to effectively increase the humidity in a room with up to 30 hours of continuous use.

Easy to Fill

Many humidifiers are tricky to fill since you have to take it apart to find the tank and then risk it spilling everywhere. However, this humidifier has a smart top-fill design that allows you to simply open the lid and fill the tank. There’s no need to take the device to the kitchen or remove any parts.

Large Capacity

The water reservoir can hold an impressive 84.5 ounces of water. This reduces the need to refill frequently and enables the unit to work for longer in both low and high modes.

Great Design

One thing that caught my atention with this unit is its simplicity and minimalistic feel. It’s also a huge plus that it does not occupy much space in my area which could be useful if you are living in a small apartment.

The Cons

Slightly Noisy

This humidifier tends to create a slight whine noise that can be annoying.

Additional Specs

Working Hours on High Setting 12 hours

7. Everlasting Comfort Humidifier With Essential Oil Tray

Best Humidifier with Essential Oil Tray

If you’re looking for a real humidifier with the additional option of a diffuser, the Everlasting Comfort humidifier is for you. This device is equipped with an impressive capacity that will last you up to 50 hours of continuous mist. In addition, it has an essential oil tray where you can add a few drops of your favorite oil.

To increase its efficiency, the air fan will distribute the cool mist as well as the scented oils through the air. Furthermore, it’s very effective at balancing humidity for an optimal home environment.

The Pros

Large Tank

This humidifier is able to run for 50 hours at a time thanks to its 1.6-gallon tank. Furthermore, it has a very high mist output due to ultrasonic technology. It can also cover large rooms of up to 500 square feet.

Essential Oil Tray

Instead of adding a few drops of essential oil directly into the water tank, you can add the drops to a special tray. This resembles that of regular oil diffusers. The oil is then circulated into the mist by the humidifier air fan.

Balances the Humidity

Too high humidity isn’t good, but neither is too low humidity. This humidifier works effectively at keeping the humidity to a balanced level above 30 percent. It won’t cause dampness or other issues caused by high humidity.


There’s no need to fill the tank with distilled or filtered water, simply fill it straight from the tap. Plus, there are no expensive filters that need to be replaced regularly — you save time, effort and money.

The Cons

Tricky to Refill

In order for you to refill the tank, you have to remove the top and flip it upside down. However, there can be a significant amount of condensation that flows out as you flip the device.
