Best Ultrasonic Essential Oil Diffuser Reviews

1. InnoGear 2nd Version Essential Oil Diffuser

InnoGear 2nd Version Aromatherapy Essential Oil Diffuser Ultrasonic Diffusers Cool Mist Humidifier with 7 Colors LED Lights and Waterless Auto Shut-off for Home Office Bedroom Room

The InnoGear 2nd Version Essential Oil Diffuser is a unique but reliable type of ultrasonic essential oil diffuser that uses cool mist to disperse oils. It is a small yet straightforward diffuser that works best in small or medium-sized spaces.

Review

This is an inexpensive product that is made out of plastic and has its fair share of manufacturing issues, but the way that the manufacturer handles those problems and how most of the product holds up makes it worth the investment.

This product has three different working modes (intermittent, light only, and continuous) that you can easily switch between. While the tiny reservoir makes it hard to use this effectively in a large space, that same small size makes this compact diffuser perfect for small spaces or even for your office.

When the water is out on this model, it will automatically shut off. Since the mist produced is very fine, you will notice the scent almost immediately if you use this in a small space.

The simple design of this model is also worth mentioning. While there are seven different colored lights and a few lighting modes, changing between these modes is still easy to do. Once you check out the user manual, you’ll find that you can work with this product easily without much of a learning curve at all.

Pros

  • Easy to use
  • Shuts off automatically
  • Compact and lightweight
  • Quiet operation
  • Not too bright

Cons

  • Continuous mode only lasts three hours
  • Not good for large rooms
  • “Mode” indicator light cannot be turned off, just the big light

2. URPOWER Essential Oil Diffuser

URPOWER Essential Oil Diffuser 150ml Wood Grain Ultrasonic Aromatherapy Oil Diffuser with Adjustable Mist Mode Waterless Auto Shut-off Humidifier and 7 Color Changing LED Lights for Home Office Baby

The URPOWER Essential Oil Diffuser is an ultrasonic essential oil diffuser that can be used in small to medium-sized rooms with good effectiveness.

Review

The first thing that you are likely to notice about this diffuser is the unique design that it offers. Available in three different color palettes, the rounded edges and a unique misting portion will help it become more than just a diffuser. You could almost consider it a type of home decoration.

The water reservoir on this model is relatively small at 150 milliliters, but the diffuser can effectively humidify and scent rooms with a size of up to 215 square feet with ease. The mist on this model will run in two different modes: intermittent or continuous. Depending on what mode you choose, it can run for up to eight hours.

The light on this model only comes out of the top and bottom, so it’s not as glaringly bright as the LEDs on some models. That is nice if you want to use this while sleeping, but the color change still gives off a nice aura throughout your usage time. You can also easily adjust the color and timing of the lights, which is very convenient.

Additionally, URPOWER really wants to be sure that you like this diffuser if you purchase it. That is why the model comes with a limited one-year warranty in addition to a 100% money-back guarantee for 90 days. If you hate it, they’ll do their best to make it right ASAP, so what is there to worry about?

Pros

  • Light can be turned off completely
  • Compact size
  • Runs quietly
  • Easy to clean
  • Available in different colors
  • Can work as a decor

Cons

  • The power cord connects at the bottom.
  • Can only use a few drops of oil at a time
  • Cannot humidify large rooms effectively

3. DLIUZ 550ml Essential Oil Diffuser

DLIUZ 550ml Essential Oil Diffuser, Ultrasonic Cooling Spray Humidifier, 7 Color LED Changing Lights Adjustable Mist Mode Waterless Auto Shut-off (Brown)

Next, let’s discuss the DLIUZ 550ml Essential Oil Diffuser. This model is another circular-type diffuser that functions very quietly and can be used in any type of room.

Review

The DLIUZ 550ml Essential Oil Diffuser is a small-sized diffuser that can work in rooms up to medium sizes, but it isn’t quite strong enough to properly humidify large rooms even if it does have a larger reservoir tank than many models. That reservoir tank mainly helps in extending how long this model can run without being refilled.

Depending on what type of settings you are using while operating the diffuser, you can expect this product to last for 10 hours on high fog settings. This fog is great at filling large spaces with a scent but is less effective at humidifying if you are looking for something that does both.

The modernly finished diffuser uses ultrasonic technology to diffuse the essential oils, so you can be sure that any added benefits that the oils have will not be destroyed by heat while they are being dispersed. You should also know that a single mist button helps you to set both the timer and the strength of the mist. This can be confusing at first, but once you learn that you must long press to change the strength and press quickly to change the timer, you’ll be able to operate this diffuser with relative ease.

Pros

  • Unique, wood grain design
  • Light color and brightness can be adjusted
  • Easy to operate
  • Automatic shutoff feature
  • Operates for a long time

Cons

  • Setting the timer can be confusing at first
  • Too small for a very large room
  • Can be hard to refill

4. Lissetti Aromatherapy Diffuser

Lissetti Diffuser for Essential Oils Aromatherapy Diffuser Ultrasonic Aroma Diffuser Wood Grain Cool Mist Humidifier for Bedroom Kids Room Living Room Study Yoga Office

The Lissetti Aromatherapy Diffuser is our next product, and it has a similar wood grain design as the last option. However, this model differs in the features and functionality.

Review

The Lissetti Aromatherapy Diffuser is an ultrasonic essential oil diffuser which has BPA-free, 300mL reservoir. This reservoir is in the middle-range when it comes to sizes available for essential oil diffusers, but it is big enough to ensure you can run the diffuser for up to 10 hours depending on the mist setting that you are using.

The light on this model is sleeker than it is overpowering. While some diffusers have a light that takes up the whole diffuser, this one only has a small light strip that can be rather soothing. If it is still too bright for you, you can use the buttons to change it to a dim mode for a more relaxing atmosphere.

We also want to point out that this model has a 30-day money-back guarantee and a one-year limited warranty. If you receive a faulty product, hate the design, or it doesn’t last as long as it should, the company will be there to help fix this problem for you. This can make a huge difference in how it performs!

Pros

  • Light can be turned off
  • Automatic shut-off feature
  • Mist intensity can be changed
  • Quiet operation
  • Stylish
  • Risk-free purchase

Cons

  • Condensation can drip while refilling water
  • Too small for big rooms

5. TaoTronics Black Essential Oil Diffuser

TaoTronics Black Essential Oil Diffuser, 300ml Aromatherapy Diffuser with Triple Mist Outlet ( Natural Candle Light Aroma Diffuser, Ultrasonic Humidifier, Diffusers for Essential Oils) - Coffee

The last option of ultrasonic diffusers that we have today is the TaoTronics Black Essential Oil Diffuser. It is a great model that offers full-touch controls and a candle-flicker lighting option.

Review

The design of this diffuser from TaoTronics is very unique, and you probably haven’t seen anything like it before. The pyramid-like light top can be alternated in color very easily, and you can even set it to a unique candle setting, which we had never seen before. When running on candlelight mode, the light will give a soft flicker just as a candle does, and this is a very comfortable and warming feature.

This has a 300mL capacity reservoir, and it can be run for up to 12 hours depending on the mist setting that you choose. There are three different mist options with this diffuser. They can be easily adjusted using the full touch buttons on the front of the product.

Finally, this model is very quiet! You don’t have to worry about the operation sounds keeping you up at night, as the only sound it makes is a gentle hum, which is very soothing.

Pros

  • Unique, sleek design
  • Candlelight setting
  • Runs a long time without refills
  • Easy to set up
  • Very quiet operation

Cons

  • Scent diffusion not strong enough
  • Can be turned on accidentally while filling
