Best Ultrasonic Essential Oil Diffusers

If you are a regular user of extracts and their powerful oils, then you know that there are several ways that you can enjoy their many benefits. They can be applied topically, ingested in some cases, and can even be inhaled. Breathing in the aromas of certain essences can help you calm down or even ease any discomfort in your nasal passages.

The scents can be dispersed through your home via clay molds that hang on doors or around your neck, they can be put into a water bottle and spritzed through the air, and they can be diluted in water and put into an ultrasonic diffuser. With diffusers, the machine does the work for you. Of course, if you are not familiar with these zen machines, then keep reading. I’ll fill you in, or you can check out our list of best diffusers.

What Is An Ultrasonic Diffuser?

This little or medium-sized gadget is something that you put in the room where you would most enjoy breathing in your favorite essential oil blends. There is a basin where you place the water up to the fill line. This is also where you add drops of your favorite essence. At the bottom of the basin, there’s this little disc looking device. Now, this is the part where the science happens where I will explain in detail below. Throughout this process, a great of mists is produced and diffused in your surrounding area.

A light brown diffuser

When you plug your device in, the small disk I mentioned above begins to vibrate with high-frequency sound waves. Worry not, these waves are non-detectable by our ears. The power of the vibration breaks the water molecules apart and turns them into mists. When the mist moves through the air, the essential oils you added will move along with it. According to the Google Patent, this mechanism was invented by Hsuan-Yu Chao and Mei-Mei Tsai, although I couldn’t find out much more on these men nor any information on when the first one was used.

Why Are These So Popular?

Amazed man and woman looking in the laptop on the desk and a glass of water near the laptop inside a room. A woman with dolly ivory hair, wearinga black eyeglasses and a yellow dress. A man with havana brown hair wearing a blue eyeglasses and a blue checkered polo..

There are many reasons why folks are turning to these little mist machines when they are in need of some relaxation or some serious help with breathing. They are designed to work quietly so you can run them when you are sleeping. Plus, they come in what seems to be an endless array of designs. Not only that, many put on an amazing light show that can be entertaining and calming.

Should You Buy One?

That all depends on what you are looking to achieve what you want with your collection of scents. If you are a person who has been using plant extracts for a while, then odds are- you already own one of these little misters and are looking to upgrade so feel free to scroll down for my top picks. If you are a person who is new to the world of essential oils, then you need to consider the following things:

  • What are your goals?
  • Is this method right for you?
  • Do you have pets, particularly birds?

Let’s cover them one by one.

What Are Your Goals?

Do you have muscle pain? Well then, a diffuser isn’t the best way to cure that. You may want to check out some peppermint oil and a carrier oil so that you can make a blend that will penetrate and bring heat to that sore muscle.

Woman's back pain. Woman holding her swollen back in white background.

 

Are you having trouble focusing? This is where a diffusing may be the right move for you. Frankincense has the ability to help us stay focused when we breathe it in.

A man concentrating on his computer in a room or office. A man is wearing a gray polo shirt.

 

Do you want to improve your mood and relax? If yes, then you should consider purchasing a diffuser. This way, you can add your oil like lavender, chamomile, or ylang-ylang to combat your stress.

Is This Method Right For You?

There are several types of diffusers including cold air, burners, reeds, natural evaporation, terracotta, and plug-ins. Ultrasonic is the most popular choice for serious users. Whether or not diffusing is right for you, it is still a personal decision.

For me, I enjoy a little frankincense when I’m writing because I tend to let my mind wander. I keep one in my work area. I also like calming oils like lavender when I’m feeling stressed by deadlines. Still, I am a pet owner with a dog, two cats, a bird, and three fish. Which leads us to our next question–

Do You Have Pets?

While there are some things that are good for us, that doesn’t mean they are good for our pets. While these oils are derived from natural sources, there is no guarantee that your pet’s immune systems will deal well with it positively. Onions are natural yet can kill a dog. Diffusing around birds is not a good idea as well. That’s why we keep our diffusers in another room far away from our cockatiel because we love him and don’t want to bring him any harm.

So, you better start checking out which essential oils are good for pets and which aren’t before you start shooting them into the air. It’s always better to be safe than sorry.

Top 9 Ultrasonic Essential Oil Diffusers Product Reviews

InnoGear Upgraded 150ml Aromatherapy Ultrasonic Essential Oil Diffuser

I wanted to start with this one because I own and love it. The mist it creates can flow in a steady stream if you need it to, or you can put on the green light and the machine will decide when the room needs a break.  Larger than the original model, which was redesigned in November of 2017, this diffuser has room for 150 ml of water with as many drops of oil as you desire.

Personally, I put about 15 drops of oil in mine when I plan on using it, and it lasts for hours. If I haven’t mentioned before, it is recommended to diffuse no longer than an hour at a time and only three times per day. With this diffuser, you can put it on the green setting, and it will pause mid diffusion for you, which means you can leave it on longer.

PROS

  • Powerful scent
  • Quiet
  • Easy To Use
  • Portable

CONS

  • Reports of it not working after a short time
  • Not for folks looking for a larger basin
Who Should Purchase This Diffuser?

This model is great for anyone who travels a lot or is looking to diffuse in small spaces. It doesn’t take up much space. Even though the basin is bigger than the original model, it is still quite small, which makes this device easy to pack and simple to clean.

What People Are Saying?

For the most part, buyers love this product. It’s small but packs a powerful punch. However, some say they didn’t enjoy using it much because they received a defective device.


Young Living Desert Mist Diffuser

Young Living Essential Oil Home Ultrasonic
  • Weight: 2.2 lbs
  • Material: Polypropylene
  • Dimension: 10 x 8 x 6 in
  • Water Capacity: 400ml
  • LED: 11 individual light settings
  • Modes: High, Low, Intermittent
  • Timer: 5H, 8H, 10H

The creator of this product is one of the most reputable companies that created and distributed essential oils. That alone gives us a sense of assurance that it will be a good buy for anyone who wishes to diffuse essential oils because that’s all Young Living does- create and distribute what they feel are the best products available in aromatherapy.

It also functions as a humidifier and atomizer. Moroccan trellises are the inspiration for the design. The ultrasonic device generates 1.7 million waves per second. The strength of the vibration breaks up oils and water into mist particles. These particles are then dispersed throughout your room effectively. There are three modes of control: low, high, and intermittent. It also offers eleven different light settings which include a candle-like flicker. This is the first and only device that features that on our list.

PROS

  • Easy to use
  • Plenty of timer options
  • Plenty of lighting options
  • Candle flicker light

CONS

  • Expensive
Who Should Buy This?

I don’t think this is a diffuser for just one kind of person. But if I had to pick one out, I would say that anyone who desires to diffuse essential oils will thoroughly enjoy it.

What Are People Saying?

Everyone who reviewed the product had nothing but positive things to say. There were a few complaints about the price, but for the most part, consumers were happy.

Leknes didn’t miss the waterless shut-off, which seems pretty standard. It also works as a humidifier and has a running time of ten hours. When you purchase this, you get a 40-day money back guarantee, a warranty for 18 months, and customer service available for your questions 24 hours a day.

This next diffuser is different than the ones I’ve talked about thus far simply because it is square. While a circle is a calming design, this is a positive choice when creating a device that will be used to calm. Moreover, the square design sets this one so far apart that it’s one of my favorite designs of all the diffusers I’ve ever seen.

Of all the diffusers we’ve discussed thus far, this has the largest basin at 700 ml. It claims advanced ultrasonic technology and comes with the usual features. A 7 color interchangeable LED light that can be stopped at one color or shut off altogether. Whisper quiet technology and auto shut off are among their many attributes.

Our next diffuser has a design that resembles others with the round bottom and thin top, which makes it resembles a drop. Mostly covered with a light wood finish, this machine has the same 7 color LED light system, which glows from a thin strip around the belly of the dewdrop.

They claim their technology is cutting edge, and you will be able to use less oil with this diffuser. The company also claims the tank is “ultra-large”, but as we’ve seen already, there are other diffusers with much larger tanks. If you’re not happy with your purchase, they will send a replacement or give you a full refund.

PROS

  • Full refund if not satisfied
  • All in one diffuser, humidifier, air purifier, and ionizer.

I would say that this is a great starter diffuser because it’s a good value for the size. Also, with a small tank like that, it would be good for someone looking to diffuse a small space.

There are plenty of positive reviews for this product. One consumer felt the lights could be brighter while another said their device barely produced a mist.

The final diffuser on our list comes with four time settings and the standard waterless shut off option. The light flows through the seven colors of the rainbow. The tank is 300 ml and is covered in wood grain.

As for the design, it is rounded like most of the diffusers on the market, but it kind of looks like an egg that is changing colors, sitting in a wood grain basket. Like the others, it can work well as a night light, and it comes with a 40-Day Money Back Guarantee and an 18-month hassle-free warranty.

PROS

  • Large amount of light surface
  • 40 Day Money Back Guarantee
  • 18-month warranty

To Conclude

Now you have nine diffusers to choose from, I’m not afraid to report that my favorite of the group is my InnoGear Upgraded 150ml Aromatherapy Ultrasonic Essential Oil Diffuser.
