Oil Diffusers Reviews


1. VicTsing Aroma

If you want to make your room smell fresh and clean, this oil diffuser made by VicTsing is exactly what you need. Just put in 2 or 3 drops of your favorite essential oil and your home will smell amazing. The unit looks very nice and comes with a generous water tank, so it is ideal for average to large rooms.

Design

The diffuser is made of BPA-free materials and it features a wood grain coating for a stylish design. It is available in multiple color options – light brown, black, cherrywood red, and redwood brown. The compact design allows you to place it on the nightstand or wherever else you want. On the bottom of the unit is the AC adapter, as well as the air intake and air outlets.

  • 2 controls: the left button allows you to set the light mode and the right button to select the timer.
  • Soft rubber feet: to increase its stability.

Functionality

The mist of this diffuser is very powerful, so it can effortlessly spread the scent around the entire room. A really nice thing is that the unit also doubles as a humidifier if you don’t add any oils. The mist button allows you to set the time -1 hour, 3 hours, 6 hours, or continuous mist while the light button gives you the possibility to choose the desired light mode – the first light setting runs through all the colors but you can also click through to choose a single color.

  • Can cover up to 320 sq. ft.: the 300 ml water tank is large enough to cover large areas.
  • Automatic shut-off: if the water level gets too low, it will shut off by itself after 5 seconds.
  • Silent operation: using advanced ultrasonic technology, the unit is very quiet – reaches a sound level of 23 dB.

Ease of Use

The diffuser is very easy to use. The lid doesn’t screw on, so you just have to put the cap on. There’s a line indicator inside the water tank and it also comes with a pitcher to make filling much easier.

PROS
CONS
  • You can also use the unit as a dehumidifier
  • User-friendly
  • Easy to use and maintain
  • Durable construction
  • When the unit is on, there is always a small light that may be rather disturbing
VERDICT

Due to the generous tank water capacity, this model can provide fragrance for approximately 10 hours. It features multiple time settings and 2 color modes. In case you don’t like the light brown color, you can opt for a black, brown, or reddish brown design. Also, we consider a great advantage the generous 12-month warranty.

2. Urpower Dark Wood Grain

Our favourite diffuser is the Urpower Dark Wood Grain Essential Oil Diffuser and here is why. This unit was specially made to cover small to medium rooms without any inconvenience. The 200 ml tank water allows up to 5.5 hours of continuous mist, while the auto shut-off function lets you know every time there’s no water left in the tank.

When it comes to features, the device is very innovative. It comes with 4 time settings, 2 misting modes, 3 color modes, and 2 brightness options. The more features, the better as this mean you can set the device according to your preferences.

As about the design, the natural appearance makes it perfect for any house. In case you don’t like the dark model too much, you can opt for a light color one. Both of them come with the same features and characteristics. As about the construction, the device is made to last for many years.

PROS
CONS
  • The control are easy to use
  • Compact design
  • When lights are off, it creates a soothing night light
  • Can be used as a dehumidifier
  • The laminate cover is rather thin
VERDICT

You can place this diffuser anywhere in the house, as it will immediately freshen the air. The 200 ml tank water is large enough to provide mist for up to 5.5 hours. You can choose from multiple time settings but you also have the possibility to opt between a low or high mist. Also, you can opt for a single color or changing colors. However, the laminate cover is quite thin, so it may easily get damaged.

3. Aromatherapy – Love in a Mist

Another great option to consider is the Aromatherapy Essential Oil Diffuser. In comparison to the first two diffusers, this one has a smaller water tank, maximum 100 ml. It can work up to 5 hours but it has a lower mist output, that is 20 ml/h. The auto shut-off function is a great addition as it helps prevent any unpleasant incidents that may occur when the water in the tank has finished. Unfortunately, it doesn’t have any time settings.

For a more user-friendly experience, you can choose between a continuous or intermittent mist (30 seconds on and 30 seconds off). Furthermore, you will surely enjoy the 7 LED lights which are very soothing. You can either choose a certain color or you can set the unit to automatically change them after a preset time. For more convenience, you can also choose the brightness level.

The design of this device is a little bit different as it comes with a beautiful flower pattern. Besides the Sappire Blue, you can also choose a Ruby Red model. According to the specifications provided by the manufacturer, the unit is made of aluminum alloy, porcelain, and PP.

PROS
CONS
  • Compact design that allows you to place it anywhere you want
  • Unique pattern
  • Easy to refill and clean
  • Comes with a 67-inch cord
  • The scent is not too strong
VERDICT

This diffuser features a 100 ml water tank, so we recommend it for small rooms. It has a beautiful design but is more fragile as is made of porcelain. You can choose from 2 misting modes and 2 color modes for a relaxing atmosphere. Unfortunately, you can’t set it to work for a certain time and the scent doesn’t resist for too long.

4. Coosa Aromatherapy

Next in our list is the Coosa Aromatherapy Essential Oil Diffuser. The unit is ideal for smaller rooms, such as the office or the bedroom. The 100 ml tank water allows a working time of approximately 4 hours, while the automatic shut-off feature is definitely a great addition. Using it is quite simple, you just have to add your favorite essential oil and let the great scent invade your home.

Some of the most convenient features this model come with include the 4 time settings and the 2 color modes. The 7 beautiful lights create a relaxing atmosphere, helping you release the stress at the end of the day. Unfortunately, you can’t adjust the light intensity.

This particular model features an interesting glass marble pattern that you will surely love. You can choose from 5 different patterns for a perfect match with your home decor. The base is made of PP and ABS, while the cover is made of glass.

PROS
CONS
  • Beautiful design
  • Quiet operation
  • Durable cosntruction
  • Easy to use
  • Rather heavy
VERDICT

Unlike the other models, this one is a little bit larger and heavier. It is made of multicolored glass, which gives it a stylish appearance. The 4 time settings allow you to customize the working time and you can set the lights to a particular color or to changing colors. However, there are no brightness options to choose from.

5. InnoGear Aromatherapy

The InnoGear Aromatherapy Essential Oil Diffuser is perfect for any small room, being very efficient and easy to use. Just add 100 ml of water in the water tank together with your favorite essential oil and enjoy the nice smell. In intermittent mist mode, the unit can work up to 6 hours. Additionally, for more peace of mine, the unit shuts off automatically, when there’s no water in the tank.

In terms of mist, you can choose between intermittent or continuous mist, according to your preferences. In what concerns the lights, you can either freeze one of the 7 colors, or you can run through all colors. Also, you can choose between bright and dim light to create the perfect atmosphere.

The unit has a simple, yet attractive design, being available in one color only, that is white. The upper is made of PP hard plastic to extend its durability and there are different buttons to set the time and the lights.

PROS
CONS

  • The lid may get stuck if not properly placed
VERDICT

This model is available only in white color, featuring a simple design that matches any modern home decor. Additionally, the unit is backed by a 12-month warranty.

6. ASAKUKI Premium

This is another great diffuser that caught our attention. Just like the other models, it uses ultrasonic technology. But it differentiates when it comes to the tank size. It has a capacity of 500ml, so is perfect for average to large rooms. Depending on the selected mist mode, this model can work between 10 and 16 hours. Additionally, it doubles as a humidifier. As a result, it can maintain the indoor humidity level at 50%. This will help eliminate bacteria and viruses, reduce the risk of developing allergies, improve your immune system, and so on.

As we’ve said before you can choose between 2 mist functions. The low mist setting has a rate of 30 ml/h, while the high setting can deliver a mist of 50 ml/h. Furthermore, there are four time settings available: 1, 2, or 3 hours, and a continuous mode. There’s even a LED function with 7 colors. You can adjust the brightness of the colors and you can choose between a fixed or auto color cycle. When the water runs out, the unit will turn off automatically to prevent overheating.

The diffisuer is made of environmentally friendly material to better enjoy the benefits of the essential oils. The PP material is not only safe but also durable. It comes in 2 color options, that is yellow and black and is warranted for a period of 1 year. In case you don’t like how it works, you can receive your money back within 6 months from the date of purchase.

PROS
CONS
  • Features an automatic shut-off
  • Made of PP material which is eco-friendly
  • Can also be used as a humidifier
  • Features a LED light function that works independently from the mist mode
  • A little bit noisy
  • The controls are not very user-friendly
VERDICT

Without paying too much money, you can have both a diffuser and a humidifier. The unit works pretty well and a full water tank can deliver mist for many hours. It looks nice and is made of safe materials. It doesn’t heat up and is easy to clean. The only major drawbacks are the fact that it is a little bit noisier than other units and the controls are not that intuitive.

7. ArtNaturals Aromatherapy Diffuser

Just like the other models, this one too uses ultrasonic technology, so you will be able to enjoy a smoke-free mist. The 150 ml water tank can deliver up to 5 hours of mist, depending on the selected mode. It is ideal for small to medium rooms, like the bedroom or the office.

You can control the mist output by selecting one of the 2 modes available: continuous mist mode or timed mode – 1 or 3 hours. Once it runs out of water, the diffuser will shut off automatically. It also features a 7-color LED function. The light mode is independent of the mist mode and you can set it to run through all colors or just one.

The diffuser is made of BDA-free materials and has a diameter of approximately 4.5 inches. You can purchase it separately or with ArtNaturals essential oils. This pack comes with 8 oils, including tea tree, lemongrass, rosemary, and others. The product is backed by a 1-year warranty.

  • Comes with 8 essential oils
  • You can opt for a timed mode or continuous mode

VERDICT

The diffuser is pretty small, so it works best in medium-sized rooms . It comes with basic features, like the automatic shut-off and the timer. Also it has a LED function and comes with various essential oils. The only disadvantage is that it is a little bit tricky to open it and it has a thin wood cover so its durability is questionable.

8. Pure Enrichment PureSpa

This diffuser made by Pure Enrichment features a simple and elegant design and a user-friendly operation. The water tank has a capacity of 100 ml, thus being able to provide a steady mist for up to 7 hours. It is ideal for areas of up to 250 sq. ft. and it can be also used as a dehumidifier – without essential oils.

In order to use it, you just have to add water – includes a measuring cup to add the desired amount of water – and add (if you like) several drops of your favorite essential oil – 3-5 drops are more than enough. Then plug the unit and turn it on. You also have the possibility to turn the LED light setting on enjoy the color changing lights – blue, green, red, yellow, purple.

This model is 5.2 inches long, 4.6 inches wide, and 8.2 inches tall and it is very lightweight. Additionally, it is made of BPA-free plastic and features an automatic shut-off function – turns off when the water tank is empty. The unit comes with an ETL certification and a 2-year warranty.

How Were the Products Rated


The main purpose of our comparison chart is to help you better differentiate the products in terms of performance, features, materials, and so on. For this, we searched all the relevant information about each of the 5 oil diffusers. While they may have some common characteristics, there are also things that differentiate them. Here are the most important characteristics explained.
  • Tank Water Capacity

    As you can probably guess, the larger capacity, the less frequently you will have to add water in the tank. This also means you will have more time to enjoy the scent in your room until the unit remains with no water. There are many units that can hold 100 ml, but we also chose some models that are more convenient from this point of view. Therefore, the VicTsing Aroma and the Urpower Dark Wood Grain come with a tank capacity of 300, respectively 200 ml. Of course, there are models that can hold more water but this automatically means a larger and heavier unit. A diffuser with a larger tank can diffuse water for more time, but this doesn’t necessarily make it appropriate for larger rooms.

  • Working Time

    The working time or operating time refers to the period of time the unit can work without having to add more water. The operating time differs from model to model, so you can find units that work for 3 or 4 hours and units that work for 9 or 10 hours. If you take a look at our comparison chart, you will see that the VicTsing Aroma features the longest working time, that is 10 hours. This makes it very convenient as you won’t have to add water too often. The other models can operate up to maximum 5 or 6 hours, depending on the mist output.

  • Auto Shut-Off Function

    All our models come with the auto shut-off function and for good reason. This feature prevents the unit from burning out when there’s no water left in the tank. Even if you let the device on during the night and the water runs out, you can be sure you will be safe, so there’s nothing to worry about. Safety is very important for many manufacturers and most of them consider this feature necessary for a risk-free operation.

  • Mist Rate

    The mist rate represents the quantity of water the unit delivers during an hour. The quantity is measured in milliliters per hour and the more mist output the unit releases, the more scented the room will be. In general, a unit which delivers more mist is recommended for larger rooms, such as the Urpower Dark Wood Grain. In high mist mode, this unit has a mist output of 70 ml/h. The model with the lowest mist is the Aromatherapy Essential Oil Diffuser, being suitable for small rooms. Some units allow you to select the quantity of mist you want to be released or to set the unit to release the mist at certain intervals of time (e.g. once per hour, once per two hours, etc.).

  • Lights

    Most of the available diffusers come with built-in lights. The lights can be used as entertainment, to boost your mood, or as night lights. The number of lights differs from one model to another, but all the products selected by us feature the same number, that is 7 lights. For more convenience, you have the possibility to stop the lights at one color or to set them to change automatically. Additionally, you can also opt to run the unit without any lights.

  • Ultrasonic Technology

    Each model presented in the table comparison chart uses ultrasonic technology to diffuse the water. In comparison to other available diffusers, they don’t use heat when producing the vapors. When it comes to essential oils, it was discovered that the heat has a negative impact on their composition and properties. So, instead of heat, the ultrasonic models use vibrations that don’t damage the essential oils. The ultrasonic diffusers use electronic frequencies to make these vibrations, being measured in MHZ (megahertz). One MHZ represents one million hertz or one million cycles per second. As you can see, 4 of our selected models use an ultrasonic rate of 2.4 MHZ and only one, the Coosa Aromatherapy uses an ultrasonic rate of 3 MHZ.

Miraculous Benefits of Essential Oils


An oil diffuser is not used only to provide fragrance and remove bad odors. When you add essential oils it comes with many other benefits for your health. Even though not many people know this, an this unit can eliminate stress or improve sleep quality just by adding oils that have special properties. The therapy that uses essential oils extracted from various plants, flowers, roots, and others is called aromatherapy. The origins of this therapy dates back around 3,000 years ago and it’s believed to have magical effects on our well-being. There are numerous health benefits of aromatherapy but we will only present you some of them. Each oil has certain therapeutic uses and there are many to choose from.

  • Antimicrobial Properties: You can use your oil diffuser to destroy microorganisms as viruses, bacteria or fungi. One of the most effective essential oils for cleaning the indoor air is the cinnamon. It has natural antimicrobial properties that keep you away from all sorts of diseases and allergies.
  • Reduce stress: Stress is very common for many people and it can have negative impacts on your health. It can be caused by different factors, including difficulties at work or school, significant life changes, financial problems, and so on. The best essential oils that will help you better handle the stress are lavender, chamomile, or bergamot.
  • Better Sleep: For those who have trouble getting asleep or suffer from insomnia, specialists recommend lavender and eucalyptus oil. Just by adding a few drops in the unit, your night’s sleep will be greatly improved and you will wake up in the morning full of energy.
  • Pain Relief: If you have headaches or other persistent pains, you can use oils like eucalyptus, rosemary, or ginger. Just a few drops in the diffuser will help you eliminate aches and pains in a natural manner.
  • Stronger Immune System: When you inhale certain oils you can boost your immune system. A strong immune system is crucial in fighting against diseases and infections, so you have to help it become more powerful. In many cases, a chaotic lifestyle can weaken the immune system and increase the chances of getting sick or develop certain diseases.

Trustworthy Brands


Gaining the trust of the customers takes time. The most important aspect in building a good reputation is to manufacture high-quality products that are both performant and durable. Unfortunately, not all companies succeed in creating a strong brand and there are many reasons why. From inefficient customer service to poor-quality products, some brands simply disappoint you and eventually they lose your trust. But we are not here to talk about these brands, on the contrary, when it comes to ultrasonic oil diffusers, we will present you the most reliable ones.

For a larger room, we recommend you VicTsing Aroma or Urpower Dark Wood Grain . The first one has a tank water capacity of 300 ml while the second one has a tank of 200 ml. The other 3 models are ideal for smaller rooms and we particularly like Aromatherapy Essential Oil Diffuser . It features a nice flower pattern design that you will simply love. Also, it is very compact and lightweight. However, for this model, you will have to pay more money, but we believe that is worth it.
