So sit back and read along.

So what exactly is a BPA free essential oil diffuser?

Well, before we go any further into our list today, let us first take a look at something, which we think a lot of you would be curious about.

We all know about and are familiar with an oil diffuser, and how it generally works. Now, what is a BPA free one?

BPA essentially stands for Bisphenol A and is a sort of a chemical that is used to reinforce plastic in many industrial processes. They are quite commonly used in producing a variety of inorganic products such as compact discs, automobile components, paint coatings as well as adhesives. 

They are also utilized in making materials that can substitute the use of metal, glass, and even wood in a particular product. 

Resins and even varnish are also some of the things that BPA is used to make. And as it relates to phenols, they are used in the manufacturing of antiseptic products as well, along with polycarbonate plastic products. 

All in all, BPA can be very harmful when inhaled for a longer period of time, and that is exactly why there has been an ever-growing demand of BPA free essential oil diffusers in recent times. 

And here are our top 10 picks of the best BPA free essential oil diffusers in the market today:

1. SmartMist Aromatherapy Essential Oil Diffuser 

What do we love about it?

The SmartMist Aromatherapy Essential Oil Diffuser is one of the best when it comes to humidifying the air in your workspace and bedroom quickly and effectively. 

However, its best features lie in the aromatherapy that it’s able to provide and how effectively it can spread the mist throughout the room. 

No products found.

And unlike most other essential oil diffusers out there today, this model from SmartMist works without emitting a single noise. Maintaining the device and refilling it is quite easy as well, and it has the capacity to help you relax for hours on end. 

In terms of design, SmartMist has provided this diffuser with a very sleek and modernistic body.

It has a wood grain finish along with a chrome accent which helps it compliment any type of decor that it may be housed in, making it a very elegant decorative piece for your room.

What did we not like about it?

The SmartMist disappoints when it comes to the total volume and capacity of essential oil that it holds. 120ml is rather small in comparison, which in turn only works till up to 8 hours. 

  • One of the most effective BPA free essential oil air diffusers
  • Very easy to maintain and refill
  • Operates without a single noise; you won’t even know that it’s there 
  • Oil holding capacity is rather low in comparison, and can only give off scent up to 8 hours 

2. Nexgadget 400ml BPA Free Ultrasonic Essential Oil Diffuser

What do we love about it?

The Nexgadget 400ml diffuser is one of our absolute favorites and contains some of the best features that one can ask for in an air diffuser.

One of the diffuser’s best features by far is its amazing capacity. With 400ml of storage, it can effectively last for over 12 hours, where it breaks down and disperses a mixture of essential oil and water into a cool mist.

  • Timed Setting and Mist Control:4 timed setting options: 1...

It also comes with an auto-shutoff system which automatically turns off the machine once the water goes dry.

The body is made to support anti-corrosive abilities, which means that the diffuser will in no way get damaged or disintegrate when kept in contact with citrus oils and will ultimately last you a very long time. 

It also has a seven light option which helps it provide a very pleasant hue in dark rooms.

What do we not like about it?

When it comes to some of the cons of this machine, the first thing that comes to our mind is how it doesn’t work as effectively when the water level reaches below 250ml. 

Moreover, it also makes a sort of a trickling noise the older it gets.

  • Comes with a time and mist control settings for better convenience
  • Comes with an ultrasonic technology for better effectiveness
  • Seven light option for creating ambient hues 
  • Doesn’t work as well when the water level goes below 250ml
  • Makes a trickling sound after a few months of use

3. Essential Wellness Essential Oil Diffuser   

What do we like about it?

This diffuser model from Essential Wellness possesses one of the most advanced ultrasonic technology out of all the models on our list today.

And this is one of the reasons why the diffuser is able to perform a partially dual feature where it functions both as a diffuser as well as a humidifier. This will help keep your skin moist, and with the additional time duration settings, you can customize the hours on the device as much as you want.

The device also comes with a lot of different colors and lighting options, and you can switch your light mood preferences from white, green, purple, pink, blue, yellow, green and red whenever you want. 

In terms of operation, it’s pretty efficient and can diffuse across a standard room rather well.

What do we not like about it?

Even with the different hour settings, the lower capacity of this diffuser doesn’t allow it to run for long. It will need frequent refills, which might be a bit frustrating for those who are looking for a device that works for longer.

Moreover, the device lacks an auto-off system as well. 

  • Comes with a very advanced ultrasonic technology
  • Is one of the more user-friendly models out there
  • Functions both as a diffuser and a humidifier
  • Works efficiently within a standard room size 
  • Doesn’t have an auto-off function 
  • Doesn’t run for a long duration of time 

4. URPOWER OD-A001 Real Bamboo Essential Oil Ultrasonic Diffuser

What do we like about it?

Now, what makes us absolutely love this diffuser from URPOWER is that it comes with an adjustable mist mode feature.

The mist mode has 2 specific working models: continuous mist and interval mist. The device will run for 3 straight hours in continuous mode and around 8 hours in interval mode. 


The ‘waterless auto shut-off function’ is what makes it so very efficient and allow it to diffuse for a longer time. And when you’re asleep or out, the feature will automatically switch off the device once the water runs out. This allows the diffuser to work for longer and not get damaged all that quickly.  

Additionally, the 7 light changing feature will allow you to provide your room with an ambiance that can help you relax after a stressful day.

What do we not like about it?

Much like most other diffusers, the URPOWER too is plagued by a lower capacity. The attractive natural wood design and finish restrict its overall oil storing capability as it can house only 160ml of it. 

So, you will have to refill it regularly.

  • Very attractive natural bamboo design that can fit any room setting
  • Has two working mist modes for better versatility
  • Waterless auto shut-off mode that increases durability
  • 7 light feature for customizable ambient settings 
  • Houses only a 160ml capacity and will require regular refills 

5. URPOWER 400ml Wood Grain Diffuser

What do we like about it?

This URPOWER model comes with a much higher oil storing capacity than the previous one. It is able to store around 400ml, and you will be able to enjoy an entire night’s worth of relaxation with each refill. 

This diffuser too comes with a high and low mist setting, and you can set the diffuser flow to 1H, 3H, and 6H setting according to your needs. The light features come with bright and dim modes as well and can help create a very soothing effect.

  • 400ml Large Capacity: Large water tank can hold 400ml water....

Another aspect of the diffuser which we absolutely love is its incredibly attractive dark wood grain design. It’s very pleasing to look at and can improve the aesthetic appeal of any room.

Each of its features is also easy to use, and by just ‘long-pressing’ the buttons, you can change between the different mist modes and meet your preferences. 

What do we not like about it?

Unlike the other models on our list today, this diffuser requires a lot of upkeep and maintenance as the nozzles tend to get clogged very easily.

Hence, you will have to empty out the tank and clean it thoroughly from the inside out with a soft, dry cloth every three to four days. 

  • Has a large 400ml capacity that can last for hours
  • Customizable diffusion settings to better meet your preferences
  • Appealing dark wood grain design can fit any room perfectly
  • Light options come with bright and dim settings 
  • Maintaining the diffuser is not as easy as you might like it to be 

6. InnoGear Ultrasonic Cool-Mist Aromatherapy Oil Diffuser, 150 mL

What do we like about it?

This cool-mist diffuser from InnoGear is a very popular model today, and it’s not all that surprising why.

Ths InnoGear is a 5-in-1 unit, which entails that it’s a diffuser, a small humidifier, an ionizer, an air purifier as well as a night light. It is capable of providing the perfect amount of moisture in the room and helps with certain conditions such as stuffy noses, sinusitis, dry lips, dry skin, etc.

  • Upgraded 150ml Capacity: Compact, optimized design with a...
  • Worry-free Safe System: The diffuser will automatically shut...

The auto shut off feature allows it to automatically turn itself off when it runs out of water, while the advanced ultrasonic system helps it to cover 100 to 150 square foot area of space very easily.

Moreover, the device comes with 3 operating functions as well, along with an intermittent mist of 30-second on and 30-seconds off, so that the effects last longer and the device doesn’t use up the oil all that fast.

What do we not like about it?

A 150ml capacity is again rather small in comparison, and the device may not work for all that long a time. So it might not be all that appealing if you want it to run overnight.

  • Is a 5-in-1 unit and provides some of the best value for money
  • Provides the perfect moisture level for helping out with stuffy nose and sinusitis
  • Has 3 operating functions for versatile usage 
  • Small capacity and might not be a good overnight diffuser option 

7. VicTsing Ultrasonic Cool-Mist Aromatherapy Essential Oil Diffuser, 300 mL

What do we like about it?

If you’re looking for an essential oil diffuser which has a very zen-like feel to it, then this model from VicTsing is precisely what you’re looking for.  

Its faux wood grain covering makes it a very attractive and appealing accessory to have around the house. It supports a liquid capacity of 300ml, which is just fantastic, and it’s capable of working all night long, to provide you with a very pleasant sleeping experience.

No products found.

The diffuser comes with four-time setting modes, which is one more than what most other standard diffuser models provide. You can choose from 1 hour, 3 hour, 6 hour, and continuous modes depending on your preference. 

There are 2 optional mist modes you can pick from as well; strong and standard mist, so if you’re having a bad sinus day, then you can just crank up the mist concentration.  

What do we not like about it?

Though the diffuser is easy to clean and maintain, it’s not as durable as some of the other models on the list. 

It can start to show signs of wear after just 2 years of use, and it mostly starts with leakage. 

  • Has a relatively large 300ml liquid capacity
  • 4 different time interval uses that helps it to meet any requirement
  • 2 optional mist features which are rather convenient
  • Easy to clean and maintain 
  • Not as durable as other models, and may start to leak 2 years in 

8. ASAKUKI™ Ultrasonic Cool-Mist Essential Oil Diffuser, 500 mL

What do we like about it?

The Japanese ASAKUKI essential oil diffuser is quite a new addition to the cool mist producing market. 

It is very fashionably made and comes with a faux wood-grain base, and an LED 7 changing color light that illuminates only the top portion of the device giving it a unique color hue.

The base holds around 500ml of water, which is great as it can then allow the diffuser to work for long hours. But when using water do make sure that you use purified and not tap as the limescale and minerals present in tap can clog up the mist exit point.  

The diffuser is also capable of humidifying a room using essential oils with aromatherapy up to 296- to 323- square feet and up to 269-square feet with water alone, which is quite a lot. 

What do we not like about it?

The ASAKUKI is not as potent of a diffuser as we would have liked it to be. The concentrated smell of the aroma oil in the air reduces rapidly after just a few hours, and all one is left with is a faint evaporated water like smell.

  • Has a unique design that can fit any room aesthetic
  • Holds up to 500ml, which can help it to work throughout the night
  • Can humidify a large room rather effectively
  • Not as potent a diffuser as some of the other smaller models

9. URPOWER® Ultrasonic Cool-Mist Essential Oil Diffuser, Remote, 1000 mL

What do we like about it?

This is a much higher-end essential oil diffuser model from URPOWER and comes with a whopping 1000ml of liquid storage. Needless to say, if you’re looking for a diffuser that can humidify your room all day long, then this would be it. 

At an average, the device will provide mists for around 23 hours straight, and on high-mist settings, it can effortlessly provide its service for 10 to 15 hours. 


The mist output is about 50 to 150ml each hour, and the device has the ability to cover a space which is as large as 430-square feet. 

Like the other URPOWER models, it comes with various timer settings of 3, 6, and 9 hours along with continuous. The auto-shutoff feature turns the device off once it’s out of water, making it a very convenient model to have.

What do we not like about it?

It’s true that it’s a very high-quality diffuser with a much higher effectiveness, but it does take a considerably long time to atomize. It can take up to several minutes to start working, and for the mist to finally come out, so you will have to be very patient with it.

  • 100ml liquid storage helps it to work for 23 hours straight
  • Remote control features allow you to customize the mist and timer settings from anywhere in the house
  • Can humidify a very large area 
  • Can take up to a very long time to work correctly and atomize 

10. URPOWER 2nd Generation Ultrasonic Diffuser, 100 mL

What do we like about it?

Though it supports a very small 100ml liquid capacity, the 2nd generation of ultrasonic diffusers from URPOWER is some of the most potent models out there today.

The diffuser is capable of humidifying a small space incredibly fast and provides an atmosphere of intense aromatherapy, which can be perfect for your daily yoga and pilates session. 

URPOWER 2nd Version Essential Oil Diffusers,Aroma Essential...
  • URPOWER New Version: The URPOWER Ultrasonic Aroma Essential...
  • Please use 100% pure essential oils with no corrosivity,...

The small and compact body makes it a very portable device, and you can carry it around with you even to your workspace 

Maintaining it doesn’t require much; all you have to do is add a little bit of water and wipe the insides with a cotton swab. You can then pour the water out from the other side, which is the air outlet so that you avoid getting water into the unit and risk damaging it. 

What do we not like about it?

The 2nd generation 100ml URPOWER diffuser is not suited for working long hours. The capacity is not all that much, and you will have to refill it periodically if you want to diffuse your essential oils for longer. 

  • A very potent essential oil diffuser
  • Portable and compact device which you can carry anywhere
  • Easy to clean and maintain, so it lasts longer 
  • 100ml capacity is not capable of giving service for more than a few hours 

Final Thoughts
