Best Diffuser Humidifiers of 2020

Categories Humidifiers
Balancing humidity with some aromatherapy.

During dry weather, it can be uncomfortable even to breathe as you feel your lips becoming chapped and your throat drying up. However, you can make your home a little more comfortable by running a humidifier.

Humidifiers work by emitting water vapor or steam into the air to increase humidity. There are many different types of humidifiers, but lately, the best diffuser humidifiers have become very popular. These combine a cool mist with aromatherapy using your favorite essential oils.

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 2020

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. Anjou Essential Oil Diffuser

Best Overall Diffuser Humidifier

Essential Oil Diffuser,Anjou 500ml Cool Mist Humidifier,One Fill for 12hrs Consistent Scent & Aromatherapy, World's First Diffuser with Patented Oil Flow System for Home & Office
Check Price

If you’re looking to create a zen-vibe in your home, this diffuser humidifier is for you. The Anjou 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 uses ultrasonic technology that creates a cool mist that will increase humidity without dampness. The device also has a few smart features such as a timer and auto-shutoff function.

Why We Love It

Single Fill Long-Lasting

With most diffusers, you’ll have to refill with essential oils constantly to maintain the desired scent. However, with the Anjou diffuser, you’ll only need to fill it once with 30 to 40 drops of your favorite essential oil. The device claims to keep a lasting scent for 11 to 15 hours on low mode and six to 10 hours on high.

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.

Ultrasonic Technology

Increased dampness can cause issues to your furniture, floors and health. However, this humidifier uses ultrasonic technology which creates a fine and stable mist that increases the humidity without causing dampness. Also, you can adjust the speed to suit the room size — set it to high or low.

Timer and Auto-Shutoff

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

Moreover, as a safety feature, the device will automatically turn off in five seconds after running out of water. This feature will prevent damage to the humidifier.

Keep In Mind

Tricky to Restart After Timer

The timer is an excellent feature that enables you to go to sleep knowing the device will automatically turn off. However, this feature could also cause a few issues. After the timer is finished, you need to unplug it and then plug it back in to work. This can be very inconvenient and slightly frustrating.

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.

Why We Love It

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.

Keep In Mind

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.

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

The oil diffuser is able to work for five to 10 hours when on sleep mode. There’s no need to worry about getting up to refill or turn it off.


If a humidifier runs out of water, it can be damaged or burn out. However, to prevent this, VicTsing 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 eight 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.

Keep In Mind

Tricky to Get the Top Off

Why We Love It

Unlike the previous VicTsing on our list, this one has a very large capacity of 17 ounces. It can run for many hours at a time when on a low setting. Furthermore, the oil diffuser can work up to 20 hours non-stop on low mist mode.

Timer and Auto-Shutoff

Color Options

You get to choose between seven soothing colors to suit your mood. It isn’t as bright as the previous VicTsing model, but it features a very subtle LED display. As well as the seven colors, you can choose between bright and dim settings for each color — excellent for night or day.

Keep In Mind

Shallow Tank

The tank that holds the water is rather shallow, which causes a few problems when full. As you’re trying to move it after filling the tank, it can spill a little. Instead, use a watering can or bottle to fill the tank where the device will work.

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

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.

Keep In Mind

Smooth Texture

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.

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.
