Best Essential Oil Diffusers of 2020 – Inside Look!

Best Essential Oil Diffusers 2020

Looking for the best essential oil diffusers on the market?

As of 2020, there are over 4,000 electronic diffusers to choose from. Since there are so many electronic diffusers to choose from it can be difficult choosing the right one for you. Truth be told each of these devices has different features that you need to consider before getting one. In this complete guide, I’m going to show you all about electronic diffusers (or ultrasonic diffusers).

I’ve spent hours researching them and I have composed a list of the top 9 best electronic diffusers. My roundup has something for everyone; no matter how big your room is and whatever specific needs you want. So, let’s get started so you can find the one that is right for you.

What To Consider Before Buying A Electronic Diffuser


Think of this as the capacity of water that your diffuser will hold. This is measured in milliliters. For example, some popular sizes are 100, 250, 500, and 1,000 milliliters. Typically, the bigger the tank the less often you will have to fill your diffuser up with water.


Being able to control how much of the mist that comes out of the diffuser is an excellent feature. There might be times when you don’t want a lot of mist coming out. There could be times when you want a lot of mist coming out. Each essential oil diffuser will have settings so that you can control the frequency that mist is dispersed and how much of it is dispersed.

Coverage Area

Believe it or not not every electronic diffuser will work in every room. Meaning, typically they are good for a specified sq. ft. room. You should consider the area of coverage before you purchase a diffuser.


Another important feature for a diffuser is a timer. For instance, you can have it set to run for 30-180 minutes. You could possibly want to diffuse it overnight while you sleep, in 10-minute increments, or indefinitely.


Believe it or not, some electronic diffusers are louder than others. This is measured in dB. Some diffusers will beep when they turn off, which you may or may not want. Ultimately, you don’t want a diffuser that is so loud that wakes you up at night or disrupts you’re thinking while you are working or relaxing in your home or office.


Nearly, all electronic diffusers have the ability to change colors. You can use them as a night light, cycle the colors, or turn the light off completely.

Ease of Use

It should be easy to add water and essential oils to your diffuser.  There shouldn’t be a lot of work needed before you fill your diffuser up.  As an added bonus some diffusers actually come with fill lines and measuring cups.


Always consider the warranty that is included with diffusers.  Some diffusers have a longer warranty than others.  If it breaks you can easily get a new one without having to spend any money out of your pocket.

Best Essential Oil Diffusers of 2020

Down below I have selected 9 essential oil diffusers that I feel are very solid purchases. I will go over the features of each of the diffusers down below.

Plant Therapy AromaFuse Diffuser

Plant Therapy is my number one trusted brand for essential oils.  (see my review here) So, it makes perfect sense that their AromaFuse is an awesome electrical diffuser. This diffuser will run up to 10 hours of continuous mist. It will cover 500+ square feet, which makes it perfect for larger rooms.

What I love about this diffuser are the timer settings. When you press it once it will diffuse until it completely runs out of the water. If you press the button twice it will run for 2 hours and then shuts off. When you press it three times it diffuses for 15 seconds and then shuts off for 30 seconds. When you press the button four times it diffuses for 15 minutes and shuts off for 30 minutes. Lastly, when you press it 5 times it diffuses for 30 minutes and shuts off for 30 minutes.

The AromaFuse diffuser by Plant Therapy comes in 3 different colors. The colors it comes in are rose gold, wood grain, and pearl white.

The plastic is made of BPA-free plastic. It’s coated so it the oils don’t deteriorate away at the plastic. It’s a more visually appealing diffuser than other diffusers, too. The quality of this diffusers is fantastic with lots of functionality.


  • It has a tank that is 380 milliliters, but last as long as other 500 mL models.
  • Covers 538 square feet, which makes it perfect for large rooms.
  • Has LED lights which can be dimmed or you can easily turn the light off.
  • Lid easily lifts off and you just add water and put the lid back on.

  • Can’t spin the lid to control where the mist goes.
  • Higher price tag than other essential oil diffusers.

doTERRA Petal Diffuser

doTERRA is a respectable brand which I have already reviewed here.  See my full review of this diffuser here.  This diffuser by doTERRA is one of their most popular selling electronic diffusers. It acts as both a diffuser and humidifier. The first thing I noticed about this diffuser is the quality of this diffuser. It’s thought to be one of the more stylish diffusers on the market and doTERRA is a prominent name in the essential oil industry.

There is a timer set which you can set for 1,2 and 4 hours. It does act as a night light which can be either turned on or off. You can’t cycle the light colors because it only lights up as white.

The doTERRA Petal diffuser does cover 330 square feet, which does make it great for small to medium-sized rooms. Does produce mist at 37.5 ml per hour. This diffuser does last for 4 hours with continuous usage.

doTERRA is a trusted name in the aromatherapy world. They have a loyal customer base. If you can afford to pay more money it’s a great option.


  • Superior quality versus other cheaper electronic diffusers.
  • It’s a simple 3 piece diffuser which is very convenient to use.

Young Living Dewdrop Diffuser

I have already written a Young Living review which you can check out here.  Check out my full review of this diffuser here.  Most people that sign up with Young Living use the Dewdrop diffuser. It seems to be their most popular model. It does come in their “Premium Starter Kit”. It’s a simplistic but high-quality diffuser that not only diffuses essential oils it also humidifies the air.

It has one mode which runs continuously for up to 4 hours at a time before it needs to be refilled. The insert just lifts out and you fill it to the fill line. However, you can fill the water with tap water. Another popular model by Young Living the “Home” diffuser requires you to add distilled water only. Also, it does automatically shut off when it runs out of the water.

The Dewdrop diffuser can cover 320 sq. ft, so it’s perfect for small to medium-sized rooms. It can act as a night light and only has one button. The one light color is a blue color which does really look awesome at night.

The Dewdrop is quieter than the Home and Bamboo which are two other diffusers that are offered by Young Living.

If you can afford the higher price tag of the Dewdrop diffuser by Young Living I would say go for it. Young Living does have a strong loyal customer base and does sell high-quality essential oils and diffusers.

  • Good for small to medium-sized rooms.
  • Can hardly hear the diffuser when it’s turned on.

Edens Garden: Ceramic Ultrasonic Diffuser – Blue Ombre

Edens Garden is a highly respectable essential oil brand that I have used and recommend to others. You can see my full review of them here. The outer cover of this diffuser is ceramic while the interior parts are 100% BPA free.

There are several options for colors; blue ombre, mauve ombre, stone gray, and taupe ombre.

It has a 100 mL water tank. It does come with a measuring cup so you can easily fill the diffuser. Filling the water is as easy as twisting off the ceramic cover and pouring water into the tank. Then, you replace the cover and connect the device to an outlet.

The mist button controls if you want a continuous mist by pressing it once. If you press the mist button twice it will go into an intermittent mode which is 30 seconds ON/ 30 seconds off). It will automatically shut off when it runs out of water.

You can control the light by pressing the light button once, which will display the light brightly. When you press the light button 2 times it will make the light more ambient. Lastly, if you don’t want the light on you can press it again to turn it off.

  • Comes in 4 different colors.
  • Can light up at night.
  • 1-year warranty.


  • Small 100 mL tank.

SpaRoom AromaMist Ultrasonic Essential Oil Diffuser

SpaRoom makes a lot of quality diffusers. Truth be told, it was the first essential oil diffuser that I ever owned. For instance, if you go to Bed Bath & Beyond, Target, Walmart, and several other department stores you will see SpaRoom diffusers for sale.

One of the best things about this SpaRoom AromaMist diffuser is it can last for 10 hours with continuous use. But, if you use it at 15-second intervals it can last for a whopping 20 hours.

It does come in 3 different colors; black, white, and silver.

This one comes with a 300 mL water tank. It’s a very quite diffuser and shuts off automatically when the water runs out.

Overall, I have been happy with Sparoom diffusers and their essential oils over the years. The AromaMist stands out because you can use it for an extended amount of time without having to refill the water. Not to mention, for under $25 it’s a bargain.


  • Comes with a 1-year warranty.
  • Last for 20 hours with interment usage.
  • Easy to use (only two buttons).
  • Comes in three colors.
  • Super quiet.


  • Not ideal for larger rooms.

ASAKUKI 500 mL (5 in 1 Diffuser)

ASAKUKI was originated from Japan. It means “air in the morning”.  It comes in a stylish wood grain base and the top lights up. This diffuser by ASAKUKI holds 500 mL of water. It’s a mister and humidifier. You can use it as a night light with 7 different colors and you can dim each one. The colors are white, pink, purple, blue, green, yellow, and red.

There is a timer setting on the ASAKUKI which goes for 60, 120, and 180 minutes. Also, it lasts up to 16 hours with continuous usage. This is several more hours than other similar ultrasonic diffusers. It automatically shuts off when the water runs out.

Additionally, you can control the mist that comes out of the diffuser. There is a high and low setting to control the mist. It puts out either 30 mL/h or 50 mL/h. You can easily spin the top around to direct where you want the mist to go.

  • Only covers 270-320 sq. ft which is less than other similar diffusers.

  • No intermittent mode to dispersing mist throughout the day.

URPOWER 500 mL Aromatherapy Essential Oil Diffuser/Humidifier

The URPOWER (see my full review here) aromatherapy essential oil diffuser is a humidifier as well as an ionizer. You can even use it as a nightlight. It will provide you with up to 10 hours of continuous mist. It does cover up to 430 square feet of space. This makes it big enough for large rooms and even smaller rooms.

You can use the high and low mode which will disperse either a higher amount of mist into the air or a lower amount of mist. I recommend using the higher mode for larger rooms and the lower mode for smaller rooms.

As I have mentioned earlier it even acts as a humidifier. The humidifier can cover up to 230 square feet.

One really cool feature about this unit is it has a timer. You can use it for 60 minutes, 120 minutes, 180 minutes, or until it runs out of water completely. It will automatically run out of the water so you don’t have to worry about the ionizer breaking.


  • It has a large capacity 500 milliliters tank. This allows you to run it for up to 10 hours.
  • It’s good for large rooms and small rooms because of the high/low setting.
  • This diffuser is fairly quiet and puts out noise at 39 dB.
  • The lid does lift off easily and you don’t have to take an insert out before placing your water and essential oils in the device.

  • Comes with an 18-month replacement guarantee.


  • It does beep every time it shuts off which some people might find annoying.
  • Every time you hit a button it does beep which can get kind of annoying. There is no setting to mute the beeping.
  • There is no intermittent mode for dispersing the mist for 10 seconds and shutting it off and on.

How To Use An Essential Oil Diffuser

It’s actually very simple to use an electronic diffuser. All you do is remove the top and put in a few drops of essential oil. Then you put the top on and run your diffuser. Depending on the capacity of your diffusers (measured in milliliters) will depend on how many drops you should add to your diffuser.

Here is a table for adding drops to your diffuser:

100 ml3-5
200 ml6-10
300 ml9-12
400 ml12-15
500 ml15-20

How To Clean An Essential Oil Diffuser

I recommend that you clean your diffuser after every 5-7 uses. This simply means that after you have used all the water and essential oils in the device. Not if you’re using it for 30 minutes 5 times each.

It’s a good idea to clean your diffuser if you are putting in essential oils that don’t mix well together, too.

Cleaning your diffuser:

  1. Fill the diffuser halfway with water.
  2. Add 10-20 drops of white vinegar. I have read you can use other kinds of vinegar, but I would recommend just using white vinegar.
  3. Turn the diffuser on for about 5-10 minutes. This will allow the vinegar to coat the plastic pieces, walls, etc.
  4. Dump the water out in the sink or toilet.
  5. Use a cotton ball to wipe the inside of the diffuser out.
  6. Rinse the diffuser with tap water.
  7. Use a paper towel or dry cloth to dry the inside of the diffuser.


So, there you have it these are the best essential oil diffusers in 2020 to choose from. Now you can enjoy the health benefits which come along with owning an electronic diffuser.

My #1 recommendation for the best diffuser of 2020 is the AromaFuse by Plant Therapy. It is more expensive than some of the diffusers I have shown you in this article, but it’s really worth it. However, if it’s out of your price range the URPOWER 500 mL diffuser is an excellent option and it’s half the price of the AromaFuse.

Lastly, any of the diffusers I have mentioned in this article I am confident in recommending.  They really aren’t in any particular order, but I it should make it easier to pick one that meets your needs.

Do you have any questions about the products listed in this guide? I would encourage you to leave a comment down below.

  1. Hello there, 

    Thanks for such a thorough article on essential oil diffusers. I am an essential oil lover and I love the smells as well as what these oils can do for the spirit and environment.  My favorite one is lavender!

    The part of your article that I found very useful was how to clean the diffuser. I have a diffuser and I admit, I never really thought about ‘cleaning it’, and now, thanks to you, I now do I know how to, but the need to do so.

    The ‘dosage’ was also good to know…I usually just ‘put some in’ and allow it to do its thing…lol…boy, am I needing to have this ‘essential oils 101 class’…lol

    But, I do have a question?  Am I supposed to diffuse it all day?  I work from home.  Is that good for you?


    1. Hey Michelle,

      It’s very important to clean out the diffuser after 5 uses or so. It helps the device stay in good working order. Also, if you mix up the scents sometimes there are some scents that really don’t blend all that well together.

      I wouldn’t recommend using your diffuser all day long though. It’s recommended that you use it for 30 minutes and then shut it off. Go with the 30 minutes on and off cycle.

  2. Wow, I have heard good stuff about Plant Therapy over the years and used their essential oils.  I knew they sold a diffuser, but I looked at the price and was a little put off.  I did buy a cheap one by InnoGear and it’s been alright.  However, I am not all that thrilled about the mist production from the unit, though.  

    I can see that I will be trying out the AromaFuse in the near future, though!

    Thanks so much!

    1. Hey Ruya,

      I know what you’re saying you get what you pay for sometimes, though. The AromaFuse is an awesome diffuser. Also, you can get it for cheaper during the Christmas season. Plant Therapy is running all kinds of Christmas deals right now.

  3. WOW! You’ve really done your research…
    I’m a Massage Therapist and I use Essential Oils in my Practice. I absolutely love using oils during a session.
    Have you ever heard of Oreganol P73? It’s The Strongest Essential Oil for Immune System Support taken Internally.
    I only ask because it’s something you can add a few drops of with another Essential Oil and create a diffuser that can help eliminate pathogens in the air and the lungs.
    It’s something to ponder, but Oreganol P73 is Quite Expensive as well.

  4. Some diffusers are definitely more noisy than others.  The first one I got as a gift, and it was so loud I couldn’t keep it in my room because it disturbed my husband.  Thinking all diffusers were equal, I stopped using it and didn’t get another one until I actually got another one as a gift again.  LOL.  Not sure what that’s all about, maybe my house is stinky?  Ha ha.  No, it was a great diffuser and so very quiet that my husband didn’t even notice it.  There was a huge difference.

    1. Hey Babsie,

      I know what you are talking about! I have bought diffusers in the past that were so noisy that I couldn’t use them while going to sleep or throughout the day because of the sound.

      You should certainly start using a diffuser again. It can do so much more than just make the house smell nice, though. For instance, the Thieves blend when diffused can actually kill airborne germs.

  5. Yes, I agree some diffusers are really annoying and wake you up at night…This is definitely good. I would consider buying it and recommend it to everyone !.. I always have them at home but mine is making noise .. so I appreciate you by sharing this, I have five boys at home so I Have to have it Lol! This is also great for a Christmas present! Happy holiday!

  6. We just bought a diffuser and I have to say it works okay, but nothing like what you have posted here. It’s really noisy which is really disruptive while sleeping. The hissing sound can be pretty annoying, but it sounds like you have found some which are rather quiet. 

    My favorite one is Smiley Daisy 120 mL Aromatherapy Diffuser as it seems to provide the qualities which I am looking for as the one I have is rather clunky. Thanks for some great information.  Sadly, the winter months bring flus and colds and make it hard to breathe.

    1. Hey Jag,

      There are a lot of diffusers on the market. I know what you are talking about. Some of them can be very noisy.

      Smiley Daisy does make great diffusers, though. It’s certainly one of the quieter ones, too. I am confident that you will be happy with it.

  7. Never realized there were so many diffusers to choose from!

    I have used a couple cheap diffuser in the past.  However, I did have a question on fragrance oils?  Are they the same as essential oils?  I have seen that term “fragrance” on a few bottles over the years.  Really confused on what it means.

    Can you please elaborate?

  8. Wow! I was not really aware of how essential oils assist in not only sleep but overall health. My wife has a tough time sleeping and uses teas, Melatonin and bath oils, but never essential oils or a diffuser. Been looking around for a Christmas gifts, and diffusers and essential oils came to mind. The VicTsing diffuser seems like the best one for me to buy for her and will consider ordering in time as a gift along with some oils for sleep.

    1. Hey Bill,

      Essential oils are great for helping people get to sleep. I have actually written an article on sleeping issues at:

      As far as tea is concerned Roman chamomile tea is great for helping you fall asleep at night. But, also taking a bath with 7-10 drops of lavender can also help your mind and body relax and fall asleep easier.

  9. I’m a firm believer in doTERRA and their petal diffuser is truly a blessing.  I actually made the switch from Young Living to doTERRA a year or so ago.

    For years I used Young Living, but I actually found that doTERRA is much better.  I do recall my diffuser breaking and Young Living did replace it, though.  

    However, my petal diffuser has been running strong and I am much happier with doTERRA.  

    Cool site by the way.  Lots of great information on here!

  10. I’ve been using Young Livings products for several years.  I can honestly say that I have used cheaper diffusers that I got off Amazon and they don’t even compare to the quality you get with Young Living.  Meaning, the mist production was so low in the cheaper models.  However, with Young Living’s diffusers you will notice the quality right away.  

    I do have several friends that also swear by Young Living, too.  We always use their oils in our diffusers. So, I know that cheaper ones you only get what you pay for with them.  Clearly, their oils are top notch, too.  I see that you have found out the hard way that ArtNaturals isn’t pure essential oils.  I too discovered that and got my money back from them years ago.

  11. I’ve been using Edens Garden essential oils for several years.  Been very happy with them.  They aren’t as expensive as Young Living or doTERRA.  Honestly, I have used both of them before and I believe the quality of essential oils is the same with Edens Garden.  You just don’t have to overpay with them.

    However, I do have a question for you.  How big of an area does this diffuser by Edens Garden cover?  I am considering getting it.  I want to make sure it will cover my living room which is about 350 sq. ft.

    1. Hey Holly,
      I agree that their prices are on par with doTERRA and Young Living. I believe a lot of people actually start out with those companies and then discover cheaper brands that are just as good.

      I did contact Edens Garden’s customer support on your questions. This is what Amy told me, “Our Ceramic Ultrasonic Diffuser- Blue Ombre covers 300- 500 sq.ft.”

      Hope this helps!

  12. I absolutely love my petal diffuser from doTERRA. I specifically like the timed settings. Meaning you can set it for 1, 2, and 4 hours. It’s a very simple diffuser and it covers my entire living room which is actually bigger than 330 square feet.

    I believe doTERRA states that it covers only 330 square feet. But, then again doTERRA essential oils are the best! I’ve tried other brands and no one else has as high quality essential oils as doTERRA does.

    I actually have 3 doTERRA petal diffusers, though.
