The Best Essential Oil Diffuser Overall

Pilgrim Anton Essential Oil Diffuser

GreenAir Spa Vapor

Here it is, the best essential oil diffuser on the list.  After testing the top 32 diffusers sold on the web, we came to the conclusion that this unit was number 1.

The first thing we noticed when we opened the Pilgrim Anton Essential Oil Diffuser out of the box was quality.  This unit is not made from the flimsy cheap plastics that most of used are used to seeing.  It is built using a thicker rubber-like plastic that you just don’t see in any of the other diffusers we tested.

The high quality plastic is also going to help this unit stand up to more abrasive essential oils.  It is better protected than the other units you will see.

Next we noticed how clean and compact the design is.  It is very stylish and there are no excess buttons or labels.  It has a very simplistic look and feel.


Great Design – The design of this unit solidifies it as the best essential oil diffuser on the market in 2017.  It is very simplistic and will fit in great in just about any environment.

Long Run Time – Even though this oil diffuser has a storage tank in the middle of the pack, advanced technology allows it to run over 8 hours.  It easily ran through the night using just the 140 ml of liquid.

Power – When you first turn this diffuser on, it will create a fountain of mist.  It will fill the room with the aroma of your choice in no time at all.


Capacity: 140

Operating Time: 6 – 8 hours

Coverage: 250 sq. ft.

Pros: It fills the room quickly and runs for an extended period of time (for the tank size).  We also loved the sleek design that fit just about any situation.

Cons: None

The Best Diffuser For A Large Room

BellaSentials Woodgrain Cold Mister

BellaSentials Woodgrain Cold Mister

The Woodgrain Cold Mister is everything you want in a large capacity essential oil diffuser.  You can fill it up with 350 ml of your favorite oils and it will run for up to 12 hour without you needing to refill.

It is also one of the quietest diffusers on the list.  You will only hear a slight hum when this unit is running and not annoying beeps when it runs low.  With 2 available speeds, you can decide whether you want a little aroma or alot.

We chose this as our favorite essential oil diffuser for large rooms because of its size, capacity, overall look, and relatively silent operation.  This diffuser has it all and is still very competitively priced.


Lifetime 100% Satisfaction Guaranty – It is unlikely that you will not be satisfied with this diffuser, but BellaSentials will replace the product.  This also means that they will send you a new until if anything goes wrong at any time!

Long Run Time – This great diffuser has one of the longest run times on this list!  It will run 8 to 12 hours on a full tank, depending on your settings.  The large tank and long runtime make this product a great large room essential oil diffuser.

Aesthetically Pleasing – We are all a huge fan of the woodgrain look, so we might be not be impartial, but this diffuser looks great.  You can put is just about anywhere and it will fit right in.  While most of the word is looking to create products that are more modern and futuristic, BellaSentials went oldschool on us with this one.

Complete Silence – If you are looking for something that runs in complete silence, this could be the best essential oil diffuser for you.  The entire process runs in almost complete silence.  It even shuts itself off in silence when empty, instead of beeping to let you know.


Capacity: 350 ml

Operating Time: 8 – 12 hour

Coverage: 500 sq. ft.

Pros: Builds up and fills a room quickly.  It has the largest tank and longest running time of anything else on this list

Cons: Because of its large capacity, this is a large unit.  We were letdown when we opened this box and found that it was not actual wood but plastic designed to look like wood.

The Best Oil Diffuser For An Office

PureSpa Deluxe

PureSpa Deluxe

Before we write a post like this one, we search online for the best reviewed products.  This gives us an idea of which products people like so that we know what to review.  During this process, the PureSpa Deluxe stood strong as the best rated essential oil diffuser on the market.  When it arrived, we quickly found out why!

This diffuser has the ability to run for an impressive 10 hours on a fairly small reservoir.  It was very easy to fill thanks to a clearly marked fill line so you don’t need to measure beforehand.

Operating Time: 8 – 10 hours

Deneve Riverock

The Riverock is one of the most stylish diffusers on the list.  Its sleek design is the perfect additional for a modern workspace or office.  You can place it in a visible location without having to worry about the way it looks.  The tank is smaller than a lot of the other units on this list but it will still do the job on a room 250 Sq. Ft. or less.

It is very easy to use, utilizing a single button do everything you could possible need.  Use the button to turn on the unit, change the color scheme, and then shut if off.  No need to worry that you will get confused about anything with this unit.

The LED’s on this unit were also a strong point.  They were just bright enough to set the mood without being overwhelming.  You also have the option for no lights, a solid colored light, or a rotation of colors.


Sleek Look – Everything about this great essential oils diffuser looks sleek and modern.  From the dark egg shape to the “equator” ring of light in the middle.  People can’t walk by this unit without making a comment about how cool it looks.

One Button Controls – In a world where things get more difficult by the day, it is rare for anything to operate with a single button.  It makes this unit very simple and helps it stay on par

Very Quiet – Some might argue that this unit is too quiet.  It is so quiet that you can hear the splashing/slurping of the water coming out of the tank.

Size – This is a very small diffuser, so it can fit just about anywhere.  It makes for a great essential oil diffuser for office settings.


Capacity: 100 ml

Operating Time: 4 – 5 hours

Coverage: 250 sq. feet

Pros: Our favorite part about the Riverock was the design.  It is small and can you can make it work just about anywhere.

Cons: You have to be careful of the two scrawny legs that hold it from rolling away.  When you are pressing down on the buttons, you need to be careful not to snap those legs.  It also only has one power setting, when most models have at least two.

We included this unit as the runner up for the best essential oil home diffuser because of the top of the line technology.  It is able to provide you with a finer mist than any other diffuser on this list.

This was one of the first unit we tested here in the office.  We were quickly impressed by the new technology but were blown away by the fact that we could redirect the mist in any direction.  None of the other units on this list had that ability!

The lights on this unit were just enough to make an impression without distracting anyone.  Some of these units can get too flashy but the GreeAir Spa Vapor is just right.  This one produced a beautiful glow that can really make a difference in your mood.  You can also put it into blackout mode at night if you prefer to sleep in complete darkness.

Pros: Very fine mist that fills the air and stays there longer than any other diffuser we tested.

Cons: This unit is a bit on the loud side.  The white noise is what landed this product in a respectable second place.

What Is An Essential Oil Diffuser?

Essential oil diffusers are a staple in the health and beauty field.  They are what we use to diffuse essential oils into the air so that they can be inhaled.  While you can use other methods with essential oils, oil diffused are the most popular.

This alternative treatment method has been used for thousands of years in in the form of traditional aromatherapy.  Natural healers would collect natural plants and burn them while the sick inhaled the fumes.

The first historical reference to modern essential oils can be found in ancient China, Egypt, and Rome.  They were used to cover up the less than desirable smells of the times, while disinfecting the air around them.

Today, we use them in the same manner but on a larger scale.  We also have a better understanding of the benefits of each oil and how to use them now.  In fact, they are a huge part of the health and wellness of many people in modern society.

Benefits Of Essential Oil Diffusers

  • It purifies and disinfects the air around you. Removing viruses, pathogens, and bacteria before you inhale it.
  • They can change and improve your mood
  • Reduces stress and anxiety (with the right choice of essential oils)
  • They spread a desirable fragrance in any room you could possible desire.

How Do Essential Oil Diffusers Work?

Essential oils work by surrounding you with the diffused oil.  This causes the oil to permeate your body and give you the fastest results possible.  Researchers have shown that the oils inhaled this way will make their way to your brain almost instantaneously, improving mood

The diffuser itself uses heat or electricity to create mist from the essential oil mixture of your choice.  It when pumps that mist into the air around you with a small fan.
