The Best Essential Oil Diffuser Overall
Pilgrim Anton Essential Oil Diffuser
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.
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.

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.

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.
Seneo 300ml Aromatherapy Essential Oil Diffuser
This product is another great essential oil diffuser for large rooms. With a 300ml tank size and 2 different mist settings, you are sure to get what you want. A week setting can allow you to adjust this to a smaller room, while the strong setting will fill a banquet hall.
This essential oil diffuser gives you the most color options of any other on this list. It has 7 dimmable colors that can be used in 15 different light modes. It is completely customizable and allows you to get the look you want!

Capacity – This product had the largest storage capacity of all the units we tested. Holding a ridiculous 300 ml of your favorite essential oil mixture, you should every have to refill!
Great Lights – We thoroughly enjoyed all of the colors and color functions this diffuser has to offer. No matter what look you are going for, the Seneo 300ml Aromatherapy Essential Oil Diffuser should be able to pull it off. If it can’t, then you might want to invest in some strobe lights!

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.

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

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.
