Best Essential Oil Diffusers Reviews 2019

nnogear 200ml aromatherapy essential oil diffuser review

Our first stop is the InnoGear 200ml Aromatherapy Diffuser. What we like about this particular model is the design. While the whole unit is made of durable plastic, it aims to look like wood, making it a chic and stylish addition to any room. Additionally, this diffuser has a thin band of blue light surrounding it which gives it a more comfortable and relaxing feel. The light even has seven different settings so you can customize it to your preferences whenever you like.

The performance on this diffuser is excellent. Being an ultrasonic model, the InnoGear is super quiet and can operate for hours on end without you ever having to refill it. The tank holds up to 200 milliliters, which makes it one of the largest diffusers you can buy. That also means that it can provide continuous operation for up to eight hours.

Another great feature of this diffuser is that you can adjust the mist settings and the timer. This device has six-time settings for when you want it to turn on, including hourly, every four hour hours, every six hours, or continuous. The mist setting has two distinct levels so you can get the proper saturation that you desire.

The InnoGear also comes with an automatic shutoff feature for when the tank runs out of water, so that you need not worry about it shorting out or damaging itself by trying to disperse an empty tank. 


  • Whisper quiet operation
  • Elegant design
  • 2 misting options


  • Slight delay for steam to get going

Our next device is the InstaNatural Essential Oil Diffuser. This is a more compact model, meaning that it is ideal for bathrooms or bedrooms rather than living rooms or work spaces. That being said, though, you could easily have this on your desk and still reap the benefits of a diffuser without encroaching on anyone else's space. What we like about this model is that it can fit almost anywhere and it's both a night light and a diffuser. The top half of this device emits a soft blue light, making it an ideal choice for nighttime diffusion.

Due to its smaller size, the InstaNatural does not last quite as long as the InnoGear model, but it is still highly effective. It comes with a 100-milliliter tank that can disperse the oil up to 250 feet away, making it compact yet powerful. The tank lasts about four to five hours, depending on the setting you use. It does have limited customization options, however, so you don't get as much control as you would with the InnoGear.

As another ultrasonic diffuser, this unit also comes with an automatic shutoff function for safety just in case you forgot to refill the tank. In fact, there is an indicator light telling you when the tank is empty, so you get a quick reminder.

To add, it can work as a small humidifier. While not as effective as a traditional humidifier, it can provide some extra relief for those who want more humidity. Cleaning this device is a breeze, as you simply take the top off and wipe down the tank.

Overall this is a fantastic diffuser for small areas.


  • Sleek and modern design
  • Auto shutdown when empty
  • Humidifies the air as well


  • Pricier

Finally, we have the Aromatherapy Diffuser by Radha Beauty. This model is very similar to the InstaNatural unit in that it is compact and acts as a nightlight as well as a diffuser. In fact, this particular model offers seven different colored lights so that you can customize your ambiance even further. You can also set the light to move through the colors for more dynamic lighting.

This diffuser is a little bigger than the InstaNatural as far as water capacity. It can hold up to 120 milliliters, meaning that the usage can last up to eight hours. This is another ultrasonic diffuser, meaning that it has a whisper-quiet operation and creates a super fine mist that will provide relief without getting too foggy.

Overall, this compact device is excellent in small spaces like bathrooms or bedrooms, and its long-lasting function means that it makes a wonderful addition to your sleep schedule since you can leave it on all night.

This diffuser also has an automatic shut-off function to prevent any damage or electrical shortage that may occur with an empty tank.


  • Adjustable lighting
  • 6 color lighting options
  • Works with all essential oils


  • Low water capacity

Benefits of Using a Diffuser

As we mentioned the health benefits of essential oils are well documented. A diffuser simply makes it much easier for your body to feel their effects of these oils. Some of the top reasons to get a diffuser are:

  1. Aromatherapy  
    Simply put, aromatherapy is the entire purpose of a diffuser. The process is defined as using essential oils in the air to provide physical and psychological benefits to patients. Having a diffuser in your house is essentially performing aromatherapy on yourself, rather than going to a holistic healing center.
  2. Improved Sleep Patterns  
    One of the best benefits of these essential oils is that you can fall asleep faster and stay asleep longer. The reason for this is that the oils can have a calming effect on your body, using scents and plant extracts to help you drift off to sleep. Using a diffuser at night can have an incredible impact on your sleep cycle.
  3. Ambiance  
    There's nothing like coming into a room and smelling a divine fragrance. Diffusers allow you to create a tranquil and peaceful ambiance without having to burn candles or incense. In fact, you can set the mood in different rooms by using multiple diffusers at the same time.
  4. Insect Repellant  
    If you're in an area where bugs make their way into your home or living space, a diffuser is a fantastic way to help get rid of them. The oil in the air clings to insects and makes it harder to move around, so they avoid it at all costs. A well-diffused room is one that does not have any bugs or pests in it.
  5. Purifies the Air  
    Another thing that oil clings to in the air is pollutants and chemicals. For best results, you should run a diffuser for about an hour to cleanse the air first, leaving only pure cleansing atmosphere behind. The toxins in the air are removed by the oil, ensuring that you get deep, purified breaths.

    This effect can also help your breathing if you have asthma or other ailments. Congestion can also be reduced or eliminated by a diffuser as the oil will help break up mucus in your sinuses and throat. Overall, having a diffuser would reduce the interruptions that breathing difficulties may bring during your sleep.
  6. Safer than Candles or Incense  
    For many years, the best way to create a natural ambiance was through candles or incense. While these still are viable options, they can pose a fire hazard if left unattended. The best thing about diffusers is that they will not short out or cause any problems, meaning that they are a much safer alternative.

How to Choose a Good Diffuser

Now that you know the reasons why you should get a diffuser it is time to find out what to look for in a machine. There are dozens of different options out there, and each one has benefits and downsides that may not be immediately clear. When making your decision, you should pay attention to these six factors.

1. Price

As they say, you get what you pay for. By that, we mean that cheaper diffusers may seem like a good buy, but they are prone to breaking down sooner as well as not providing the same level of effectiveness. As we mentioned above, ultrasonic diffusers are better than the competition, but they can be a little pricier, depending on the brand. Overall, we suggest springing for something a bit higher end as it will offer much better results and should last a lot longer.

2. Type

We already informed you about the different types of diffusers, so it's your personal preference depending on your environment. Overall, ultrasonic and nebulizing diffusers seem to offer the best results, but that is not to say that there are not excellent evaporative or heated diffusers on the market. Choose a model that will make the most sense in your space.

3. Adjustable Options

When it comes to operation, it's better to have options than not. By that we mean some models allow you to set a timer on when the diffuser turns on, adjust the mist level, and even change the lighting effects. For our money, diffusers that give you customizable controls are far better than those that have only one setting.

4. Water Capacity

When measuring the water level in a diffuser, most units go by milliliters. The reason for this is that you don't want to oversaturate your room with too much oil or humidity so that the diffusers won't use so much water at any one time. With that in mind, however, you still want to get a unit that has enough water capacity to last for hours. Ideally, we suggest getting a diffuser that can last for at least six hours so you can have it on at night, but not all of them will offer such extended operation.

5. Room Coverage

Where will you be using your diffuser? In the bathroom? The living room? Your bedroom? Regardless of the space, you need to make sure that your unit can adequately fill the area with an oil mixed atmosphere. Most diffusers can maintain an area of about 150 feet, but some are designed for larger rooms and can go up to 250 or 300 feet.

What you do have to keep in mind, however, is that you don't want to get a diffuser that is meant for a large room and then stick it in a smaller one. The reason is that you could risk oversaturating the air and creating an unpleasant atmosphere.

6. Lighting

One of the most common accents to a diffuser is light. For some models, the light is a calm, serene glow that is similar to most electronics. For others, however, the diffuser can act as a night light or lantern. Another aspect of lighting is that some models offer multiple colors and brightness levels, meaning that you can use it as a soft ambient light or as a night light for your bedroom. Depending on where you will use the diffuser as well as the time of day it will be on, you may want to pick a model with matching light options.

What is a Diffuser?

In essence, a diffuser uses one of four different methods to disperse essential oils into the air around you. The way that most diffusers work is similar to a humidifier, in that they create a fine mist that is a mixture of water and oil. Although the process is similar, diffusers are much different than humidifiers, as their intended purpose is to lightly saturate the air with essential oil so you can breathe it in and feel its effects.

Different Types of Diffusers

When talking about diffusers, there are four distinct methods of operation. Each one has benefits and downsides, but for our money, we highly recommend ultrasonic diffusers as they usually have the best results. Nonetheless, here is how each device works.


As the name would suggest, these diffusers use high-frequency sound waves to create a fine mist. The waves break down the oil, so it mixes with the water and is emitted into the air. Ultrasonic diffusers are super quiet and can operate for hours without needing a refill. The mixture created is also ideal for most users as it doesn't use too much oil, making it more palatable.


This diffuser works in much the same way a humidifier does. A small fan blows cold air over the oil/water mixture and creates a mist. Because it has a constant flow of air, nebulizers are ideal for creating an atmosphere quickly, but that does mean that they don't last as long. Also, the fan can make more noise than an ultrasonic unit. The drawback to nebulizers is that they don't work for heavier oils as they don't get picked up by the fan as easily.


In this model, the essential oil sits on a pad, and a fan blows air through the pad so as to evaporate the oil. Lighter oils will evaporate much quicker than heavier ones, which means that you may have to replenish the supply more often.


If you want to get the smell of essential oils but don't necessarily want all of the effects, a heat diffuser is a great way to go. Heated coils warm up the oil, so it evaporates, making it faster and more efficient at filling a room than other models. However, some units can change the composition of the oil with the amount of heat used, which means that you could reduce other benefits in the process.

How to Use a Diffuser

For the most part, the best way to ensure that you're getting the most out of your diffuser is to read the instructions first. Different models can handle certain amounts of oil, which means that you don't want to overload the device and create a thick, greasy atmosphere as a result. Conversely, you don't want to use too little oil and dilute the air too much.

The basic operation of a diffuser is this: fill the container with water, and then place several drops of oil on top. The oil will sit on the water as a thin layer until it is completely evaporated. Some diffusers will remove the oil quickly, and others will take longer. Overall, the point is to create a fine mist of oil and water that will saturate the surrounding air.

For optimal results, we suggest that you start small by filling the container halfway and only using a tiny bit of oil. The reason is so you can test the effects of aromatherapy and adjust it however you like before committing to a full dosage. Some people prefer a thicker atmosphere than others, so you want to make sure you know how much oil is enough for your preferences.


So if you're ready to feel the benefits of an essential oil diffuser, be sure to find one for your home today. These handy devices can have a tremendous impact on night routine, bringing you to a well-rested state primed for a great night's sleep. Don't wait and buy one as soon as possible. You will be glad you did.​
