Advanced Aromatherapy Essential Oil Diffuser Review

Advanced Aromatherapy Essential Oil Diffuser Review

Are you considering the Advanced Aromatherapy Essential Oil Diffuser/Nebulizer?

It’s certainly one of the more popular nebulizers you might have seen in the aromatherapy world.

So, the Advanced Aromatherapy Essential Oil Nebulizer was developed by Diffuser World. This nebulizer is also referred to as the Aroma-Ace.  Don’t think one of the other got discontinued or anything.

Diffuser World sells the unbranded Advanced Aromatherapy Diffuser to other wholesale companies. This allows them to sell the product without their customers coming directly back to Diffuser World. The branded version is called the Aroma-Ace. Diffuser World has also private labeled this unit to other larger companies. They are all the same unit just branded differently for each company.

So, don’t be surprised if you hear these words used interchangeably because they are the same product.

Diffuser World does sell a number of different nebulizers (see their unique story here).  Diffuser World specializes in atomizing/nebulizing diffusers. The owner, Earl Sevy, has over 25 patents with 3 patents pending all focused in the atomizing/nebulizing diffusers. Atomizing diffusers offers 100% therapeutic benefits of your essential oils. Their lab tests show that after atomizing essential oils with the Aroma-Ace for only 15 min, the essential oils are suspended in the air for 75 min.

Clearly, Diffuser World is one of the most notable brands in the industry that sells high-quality nebulizers and stresses how much better nebulizers are versus a diffuser.  I 100% agree with them that nebulizers are so much better than diffusers like the Dew Drop by Young Living and Petal by doTERRA .  Some of the ones they do sell are the Aroma Infinity, Aroma Whisper, and Aroma Express.  But, in this review, I am going to be talking about the Aroma-Ace.

Now, let’s get started and you can learn what to expect with this popular nebulizer.


  • One of the best essential oil diffusers/nebulizers on my list. (see for list)
  • Highly trusted company. (Diffuser World).
  • Lots of control and can adjust settings to your liking.
  • Super easy to use.
  • Hooks up to a bottle so you don’t need to keep adding drops.
  • Does contain polypropylene (PP) parts.
  • No Glass Parts.
  • 5 Year Warranty.


  • Louder than other nebulizers.
  • Not as visually appealing as other nebulizers.
  • Additional accessories cost extra.

The first thing I noticed when I opened up the package and held the Advanced Aromatherapy Essential Oil Diffuser was this thing was solid.

Meaning, it was heavier than other nebulizers that I used in the past. It came with 2 empty bottles (15 mL), 2 spout attachments, 2 atomizers, and a standard power cord (already attached to the unit). The power cord is AC 110v/60 Hz 6W. However, they do offer this unit with different power cords.  For example, this one is universal which you can use it in the United Kingdom, Australia, or most notably for in hospitals.

There is nothing to assemble other than put the top attachment (the spout) on and connect it to the atomizer. Then lock the atomizer into place (no tools are required). Also, you are going to have to screw the bottle into the atomizer. There is a tube that connects from the top piece.

Unlike a lot of nebulizers, you’re not going to have to put in 20-25 drops of essential oil.  Meaning, that other nebulizers that I have used had a glass reservoir and you put the essential oils in. As I have pointed out you just screw in a bottle and turn it on.  I really do like the convenience of the Aroma-Ace.  Not to mention, when you travel with a glass nebulizer you have to constantly worry about it breaking.

5 Color Options

You do have options in terms of colors with the Aroma-Ace.

The unit that I got was black. There are 5 color options available. You can purchase it in the following colors:

  • Black.
  • Blue.
  • Bronze.
  • Green.
  • Lavender.

Just to clarify the colors of the base unit is all white with each model. The color options are just for the dials and the atomizer.

How Does The Advanced Aromatherapy Essential Oil Nebulizer Work?

There are three different dials on the front of the unit. I am going to discuss exactly what they do in more details.

Run Dial

The first dial is called the “run” dial. This is the top dial.

It’s pretty straightforward, but basically, it just turns the nebulizer on. Meaning, you will turn it clockwise to turn it on. Instead, of just staying on for 10 minutes and then turning off for a set time like the ArOmis Orbis Now Merus (see review) you have more control on how long the Aroma-Ace stays on.

The dial can be adjusted to run for 5,10,15, and 20 minutes.

Rest Dial

The second dial is called the “rest” dial. It’s the dial right below the run dial.

It controls how long the nebulizer will turn off after it emits the essential oils into the air. You simply turn it clockwise to turn it on. Just like the run dial you have the option to adjust it to run for 5,10,15, and 20 minutes.

Output Dial

The third dial is called the “output” dial. It’s the dial that is located at the bottom right below the rest dial.

What this does is control how much essential oil is emitted into the air. All you have to do is turn it clockwise more and it will start emitting more essential oil into the air.

Be very careful with the output dial if you turn it all the way to the max it can use your essential oils very quickly.

My Experience With The Advanced Aromatherapy Essential Oil Nebulizer

So, within minutes I was easily able to lock the atomizer and snap the top piece into the back of the Aroma-Ace.

Attaching Bottles

Unlike the Raindrop 2.0 by Organic Aromas (see review) you don’t have to keep adding drops to the glass tank. There is no glass tank with the Advanced Aromatherapy Essential Oil Diffuser. It’s all made out of polypropylene (PP).  Polypropylene is the same material they use for the lid on essential oil bottles. It’s very compatible with essential oils and safe.

At first, I tried to screw a bottle of peppermint (10 mL) that I had from Starwest Botanicals (see review). However, it wouldn’t screw into the atomizer.  Again, the Aroma-Ace comes with two 15 ml atomizer attachments.  The atomizer is designed to fit most 15 ml bottles. If you are like me you will find out that 10 mL won’t screw in.  So, the straw needs to be clipped so it will go into the bottle.

I would suggest using a glass dropper to get the essential oil into the bottles that are provided by Diffuser World. I did try it with my bottle of doTERRA (see review), Rocky Mountain Oils (see review), and Young Living (see review).  However, it didn’t work with my bottles by Plant Therapy (see review) because they sell their bottles in 10 mL, 1 oz, and 4 oz.  But, like I said it’s no big deal to transfer the oils with a glass eye dropper.

As I have stated, you will fill a bottle up with essential oils and screw the bottle into the unit. A plastic tube then will suck the essential oil up and disperse it into the air. I like to make my own synergies so I did make one with sweet orange, mandarin, and ylang ylang. It was a relaxing blend that I diffuse whenever I am stressed out and need to unwind for the night.

Also, I did make another synergy with peppermint, rosemary, and eucalyptus which I diffuse to help wake my body up so that I can focus on my daily task.

Third, I did mix bergamot and cedarwood for a night blend to help me sleep.  But, keep reading because I did need to install a silencer to make it quieter, which is an extra you are going to need to purchase.

But, I really do enjoy making my own blends and it might be worth it to buy a couple of extra bottles in case you want to have some already made blends ready to use whenever you want.

Also, I would highly recommend getting some glass droppers; it really makes transferring the oils from your original bottle to the bottles provided by Diffuser World easier.

Area of Coverage

A lot of nebulizers in the industry cover 600-1,000 sq. ft.  The Aroma-Ace actually covers more area.  It covers 1,500 sq. ft.

I have used mine in my office in my home which is about 200 sq. ft and I could smell the aroma in the living room.

Again, the main difference between nebulizers and diffusers is the potency and how the oils are dispersed into the air.  As I have already mentioned the oils stay in the air for up to 75 minutes when diffused for just 15 minutes.

Noise Level

Unfortunately, one of the drawbacks to using a nebulizer is the noise level. I’m not stating that they are unbearably loud. But, they are typically louder than a diffuser.

My experience using the Advanced Aromatherapy Essential Oil Nebulizer is that it’s louder than other nebulizers that I used in the past. For instance, it’s noticeably louder than the Organic Aromas Raindrop nebulizer that I have already reviewed. This can make it a drawback for people that need something quiet when they are using it for sleep.

I was unable to find the actual dB level for how loud it is. I can tell you this without the silencer the Aroma-Ace was too loud for me to use while sleeping.

However, Diffuser World does sell a silencer. It’s called the Aroma-Silencer. What it does is muffles the sound of the nebulizer. It does help reduce the sound of the unit. It will lower the dB level by up to 6-8 dB. However, it doesn’t come with the Aroma-Ace, though. Instead, you will have to purchase it separately.

When I did use the Aroma-Silencer I was able to use it to help fall asleep. It really does help reduce the noise a lot. Since the device is going to keep turning on and off it’s a great extra to buy.

Extra Timer

One thing that I found myself doing time and time again is having to completely turn the output dial off. I would do this because I would go somewhere and didn’t want the Aroma-Ace to be running while I was gone. One time I actually forgot to turn it off and when I got home I saw that the nebulizer was running for 10 minutes on and 10 minutes off for 6-7 hours. It wasted a lot of my expensive essential oil I got from Rocky Mountain Oils (see review).

Diffuser World does sell a timer, though. It’s called the Aroma-Timer. It’s a mechanical timer. I heavily prefer mechanical timers over digital ones, though. It is a programmable daily-cycle timer. What is great is it can be programmed for 48 on/off hours instead of just 24 hours.

Also, here is a cheap timer you can purchase, which is one the one I actually use with my Aroma-Ace.

Cleaning The Advanced Aromatherapy Essential Oil Nebulizer

It’s important to clean your Aroma-Ace after every 7-10 uses.

Other nebulizers that I have used in the past have glass tanks that you need to use a pipette with. This one is different and there are no glass parts. Instead, it uses polypropylene (PP) parts.

The process of cleaning this nebulizer is pretty straightforward.

Here are the steps you need to take:

  1. Pour some rubbing alcohol, Vodka, or Everclear into an empty 15 mL bottle.
  2. Remove the essential oil bottle that you had hooked up to your nebulizer.
  3.  Attach your bottle of rubbing alcohol.
  4. Attach the atomizer and to the unit.
  5. Let it run for about 5-10 minutes. Make sure you have it in a well-ventilated room.
  6. Reconnect your essential oil bottle that you want to diffuse with.

If you want to clean the outside of the unit just use some rubbing alcohol with a washrag or paper towel and wipe it down.

Lastly, there is no need to let it sit and dry completely like you would with other glass nebulizers. You can instantly use it right after running the rubbing alcohol through the unit.  I really do like this and hate having to wait 1 hour to use my nebulizer after cleaning it.

Warranty & Replacement

If you are going to spend over $100 for a nebulizer it must have a warranty.

Thankfully, Diffuser World does have a great warranty. I say “great” because a lot of other brands will sell you a nebulizer or diffuser and you only get a 6 month to 18-month warranty. So, if your unit breaks after that time period your out your money and also out your nebulizer.

Diffuser World does it different than other companies, though. Instead, you get a 5-year warranty with the Aroma-Ace.

Warranty Replacement

If ever you Aroma-Ace should break within the 5 year warranty period there is a number of steps you need to take.

Here is a screenshot that you need to follow:

Diffuser World Returns

You will need to pay for the shipping back to Diffuser World, though.

Diffuser World Customer Support

Diffuser World Live ChatIf you are new to nebulizers or aromatherapy you might have some questions.

I certainly remember several years ago when I was new to essential oils I had a lot of questions.

Diffuser World does have customer support.  So, it isn’t just like you buy a product and then are on your own to figure everything out. A lot of answers to any questions you might have can be found on their resources section on their website.

You can go to their website and get help with their live chat feature. Also, you can call them between 10:00 A.M. to 5:00 P.M. at 1-855-276-6277 (MST). If you do fill out a question on their contact form it does take about 12-24 hours to get a response.

Overall, I would say I am very happy with Diffuser World’s customer support.

Final Verdict

So, do I recommend the Advanced Aromatherapy Essential Oil Nebulizer?

Yes! It’s an awesome nebulizer that I was so lucky to get to try out.

I use it every day and I will continue to keep using it.

What I really like about it is you have more control over the settings. Meaning, that you can customize 3 things instead of just the mist production which is standard with a lot of other popular nebulizers in the industry.

Again, the essential oils stay in the air for up to 75 minutes when you diffuse it for just 15 minutes.  This is more than 3 times as long as a diffuser.  The area of coverage is a whopping 1,500 sq. ft, too.

You can buy an Aroma-Silencer, which I highly recommend to help keep the noise level down some. Also, I highly recommend the Aroma-Timer (which I used a similar timer), which can be scheduled to come on daily.

It does cost a little bit more than other nebulizers and while the extras don’t come with it I do highly recommend them, too. You can get the whole bundle at once, which will save you money in the long run.

Lastly, It’s not as visually appealing as some other nebulizers in the industry.  For me, it wasn’t a dealbreaker at all.  However, some might prefer wood grain, black matte, etc. which isn’t offered at this time.  It does come in 5 different colors, though. You do have full control over it, which is a HUGE plus.

As you can see Diffuser World has gotten a lot of positive feedback.  They do have a very active Facebook page for their business, which also has lots of great information.  They are a highly respectable brand and have lots of happy customers located all around the world.

Overall, I am so happy with the Advanced Aromatherapy Essential Oil Diffuser. I highly recommend it!  I promise that if you get one of these you will throw your ultrasonic diffuser in the trash!

  1. Thanks for this review.

    Aromatherapy has proven to be very relaxing, I heard about this a while back and decided to try it out.  I have had great results, especially with helping me relax. Having the right essential oil diffuser makes a very huge difference. 

    Thanks for providing information about some of the pros and cons of this Advanced Aromatherapy Essential Oil Nebulizer and how it works, really useful information over here, thanks.

  2. Hello,

    Thank you for providing a very informative review,

    I have used aromatherapy in the past and found that it does help with relaxation and anxiety.  Personally, I love the smell of lavender and geranium.

    However, can you use thicker essential oils with this nebulizer?  I have heard that some thicker essential oils can clog a nebulizer.  

    1. Hey Louise,

      Good question. I was actually unsure of the answer and I did ask Diffuser World. They told me you don’t have to dilute it or anything. I would recommend doing a deep cleaning every so often, in order to clean out any thicker oil or residue that may begin to clog the atomizer. I would also recommend to any customer that knows that they are not going to be using their diffuser for a while, to do the deep cleaning before they store their diffuser.

      Other brands of nebulizers I have noticed that you have a higher likelihood of clogging the nebulizer. Mostly, ones that use glass do seem to clog more often, from my experience.

  3. I have a diffuser that I got for pretty cheap off Amazon.  It’s one from ArtNaturals.  However, I am not that happy with it.  I can hardly smell it.  But, it looks like this might be a much better option.

    I am considering getting one of these diffusers. From everything I have seen on them, it looks like most people are very happy with them. However, there is a plastic tube that sucks the essential oil up right? I have always heard that plastic and essential oils should be avoided?

    Can you explain it to me some?

  4. Wow, thanks for this review.  

    I am new to essential oils and realize there is so much to learn about them.

    However, I do have a question for you.  Is it recommended to use the nebulizer/diffuser all day long?  Maybe, there are some best practices I am supposed to follow.

    Sorry for the newbie question 🙂

    1. Hey Marshall,

      Don’t worry about the newbie questions. Years ago I didn’t know a thing about aromatherapy or essential oils either.

      It’s actually recommended that you use a diffuser for 60 minutes and then shut it off. As you can see from this Advanced Aromatherapy Essential Oil Diffuser once diffused the oils actually stay in the air for 75 minutes. You can learn more about using essential oils here:

      Also, here is a complete newbie guide to learning about essential oils:

      Hope it helps!
