Top 10 Best Essential Oil Diffusers 2020:

1. VicTsing 300ml Cool Mist Humidifier Ultrasonic Aroma Essential Oil Diffuser 

The VicTsing 300ml Cool Mist Humidifier Ultrasonic Aroma is the best essential oil diffuser we were able to find. It certainly has a lot to offer.

For instance, the capacity is 300ml which makes it suitable for most living rooms, bedrooms, offices and even for some studios.

On a single water filling, it can run up to 8 hours. Once water is gone, the diffuser will turn itself off within 5 seconds.

Each user has the ability to adjust the period of time he wants the diffuser to operate. The options are 1, 3 and 6 hours. There is an additional option in which the diffusor will run continuously as long as it has water in the reservoir.

The lights implemented are based on the new technology and there are 14 total combinations. In reality, there are 7 different colors, but each hue comes with the bright and dim mode.

2. URPOWER Essential Oil Diffuser 400ml Wood Grain Aromatherapy Diffuser Ultrasonic Cool Mist Humidifier

The unit we have here is similar to the first model, but it looks completely different. The design is probably the biggest difference and the main one why it is a popular model on the market.

It is paired with 400 ml reservoir, and it can be used for rooms up to 15x15 feet in size. The length of operation for each refill is 12 hours.

The diffuser will provide heavy or light mist, and a user can choose that by pressing the mist button. As such, the mist output varies between 30 and 80 ml per hour.

Of course, you can choose the length of the unit to operate. Available options are 1, 3 and 6 hours but the continuous mode is available as well.

Seven colors of the lights are included as well. The user can choose the desired one and can toggle between the bright and dim. The diffuser can be purchased in three color options, black, bright wood and brown wood.

3. VicTsing 19dB Super Quiet 130ml Mini Aromatherapy Ultrasonic Cool Mist Humidifier

VicTsing Essential Oil Diffuser looks modern and it is one of the most affordable models out there. In a nutshell, this unit is small and optimized for users who will want to use it in smaller rooms or to carry it while on the go.

The reservoir capacity is 160 ml, and it can operate for 3-5 hours, depending on which mist option you have selected.

The atomizer plate and the inner components are based on modern technology, and there are some advantages here. The unit may be small, but the atomizer plate will oscillate up top 3 million times to dissolve the water mixture.

It will produce up to 19 dB sound which is a decent result. There are 8 colors of the lights available. The mist output is 24-40 ml per hour.

The unit has just one button as you can see. It is used to toggle between the sleep, modes, mist, and lights. This is a bit confusing, especially for beginners and it requires some time to get used to it.

4. Diffuser for Essential Oils (400ml) - Super High Aroma Output - FREE Cleaning Kit 

We liked this model due to several reasons. First of all, it is strong, well-made and it looks special in the lack of a better word. The water reservoir is 400 ml which is slightly more than similar models have. This means that on a single refill the unit will operate up to 13 hours. You can choose the duration of each operation and the available options are 1, 3, 6 or continuous.

The mist output is between 30 and 50 ml per hour. You can choose the output you need at that particular moment. There are eight light colors of the LEDs implemented into the diffuser, and you can switch between them to adapt the unit to fit better in your space or to get a specific, color-related benefit.

There are two color options you can choose, and they are the black and standard word. The unit itself is solid and looks better in person. All future owners will get a cleaning kit included in the package. Sadly, all of this comes at a price so we can’t say that the unit is affordable. It is slightly more expensive than equivalent models.

5. VicTsing 3rd Version Oil Diffuser - Ultrasonic Diffusers Cool Mist Humidifier

It is small, appealing to use and it comes in one of a kind design. All of this is related to the latest VicTsing 3rd Version Essential Oil Diffuser. The capacity is 160 ml which makes it a smaller unit on the market. On a single filling, it can operate for 6 hours.

However, the atomizer plate and the design are all new, and they are improved compared to older versions. This means that you get noise level under 20 dB and the excellent quality of the mist.

Using the diffuser is extremely simple. All you have to do is to use the buttons at the lower part of the device. You can adjust the sleep mode, which will minimize the mist output between 12 and 30 ml per hour.

In full mode, the output is increased to 40 ml per hour. Being a new model, it merely has the best controls and the most desirable ones we were able to see.

The unit is made in such a way that when it changes color, it changes the exterior look completely.

You get 300 ml diffuser and you get the ability to own a piece of art. In other words, we present you the model that is special and you can see all about it right here. The first thing to add is the water reservoir which is decent in size. The diffuser will shut itself down in a case there is no water in the reservoir and therefore eliminate the risk of overheating.

Each user can choose between 7 different LED options. This also means that the brightness can be adjusted as well. Using the diffuser is simple, easy and appealing.

The design allows for it to change the color of the upper part as soon as you turn the LED. We liked this because diffusers of this kind look stunning at night and they are excellent to use when you want to create a specific mood.

The next best thing is how easy to clean this diffuser is. You will literally need a couple of seconds and you are done.

7. Metal Vintage Essential Oil Diffusers 250ML - Aromatherapy Ultrasonic Cool Mist Humidifier for Essential Oils

As you can see this is a diffuser and humidifier that looks like no other. There are 4 different variations available and there are two options when it comes to water reservoir capacity.

You can choose between 100 and 250 ml. We tested both versions and believe a bigger one is more desirable. It has an operating time of 8 hours, and it is suitable for larger rooms.

Some features are standard. For instance, the unit has seven color options of the LEDs, and all users can choose the one they like.

The unique design, paired with this advantage makes the diffuser looks strange and a masterpiece. The noise level is under 35 dB which isn’t the best possible result.

We also must add that the mist output is 30 ml per hour which is standard for diffusers of this kind and this size.

After all, it has all you will ever need and something more.

You will get 8 hours of low mist or impressive, 12 hours in high mist setting. Choosing the one you need is simple as a press of a single button.

There are 14 LED color options to choose from. However, this is slightly different than you may believe. There are seven colors actually, and they can change accordingly. But each color comes with a bright and dim mode which transfers them into two separate color options.

The unit is very quiet while creating beautiful mist and it can be used for smaller and larger rooms.

Of course, this isn’t a small diffuser that comes with basic options. It is a full-sized model that offers all the features you will need.

The tested model is advertised as 3 in one. This means that you get a night light, a diffuser, and a humidifier. All of the three characteristics actually work and you can enjoy them for a long period of time.

The water reservoir is the most significant advantage due to the fact it has a capacity of 500ml. This means that the unit will operate as long as you need it on a single charge.

Be free to set the timer on any setting you like. The supported options are one hour, two and three hours. The atomizer plate will vibrate over 2.45 million times per second to make an impressive blend of the water and essential oil.
