Aromatherapy Essential Oil Diffuser Best Buys

#10: Viva Naturals 200ml

Viva Naturals Ultrasonic Aromatherapy Essential Oil Diffuser, Large 300ml Tank - Vibrant Changeable...

This affordable little diffuser has three settings – continuous mist, intermittent mist, and lights only – and seven different light colors to choose from. It’s ideal for smaller spaces such as home offices and bathrooms.

With an auto shut-off safety feature, you have complete peace of mind without the need to keep checking up on the diffuser while it’s in use.

It is easy to clean though it can be a little tricky to open the unit to add water and oils. This Viva diffuser would not be effective in larger rooms.

Pros:

  • Auto shut-off feature
  • Easy to clean
  • Ideal for small spaces

Cons:

  • Not powerful enough for larger rooms
  • Difficult to open to add water, oils
  • Light transition can be too quick

Value For Money?

This is a very affordable model. If you only have a small room you’ll be using it in, it’s definitely a good buy.

#9: InnoGear 400ml Ultrasonic

InnoGear Real Bamboo Essential Oil Diffuser Ultrasonic Aromatherapy Diffusers with 7 LED Colorful...

An ultrasonic essential oil diffuser, this comes with a measuring cup to help ensure the correct amount of water is added.

It is an affordable, functional, and attractive unit, although it is hard to clean.

Pros:

  • Includes measuring cup
  • Affordable
  • Good for medium-sized rooms

Cons:

  • Difficult to clean

Value For Money?

If you don’t mind putting a bit of effort into cleaning it, this is a good basic diffuser for a good price.

#8: UrPower 200ml Wood Grain

URPOWER Essential Oil Diffuser, 200ml Wood Grain Aromatherapy Diffuser Ultrasonic Cool Mist Aroma...

Presented in a stylish blonde wood grain effect, this diffuser offers a simple, clean, natural focal point and is ideal for the minimalist home or a professional therapy room.

As well as the diffuser function, this item also offers a night light option (without diffusing mist), and a humidifier function. The humidifier helps purify the air of lingering smells and pollutants such as second-hand cigarette smoke.

The diffuser is easy to clean. It is important to note that it is NOT made of wood, but is high-grade plastic, coated in wood-effect vinyl. If you’re expecting a solid wood unit, this one will feel disappointingly cheap by comparison.

Pros:

  • Easy to clean
  • 3-in-1 functionality (diffuser, night light, humidifier)
  • Ideal for small rooms

Cons:

  • Feels cheaply made
  • Would be a disappointment if you had been expecting solid wood finish
  • No auto shut-off feature

Value For Money?

This is a high-priced diffuser for what it is. It isn’t wood finish, and the functionality is fairly standard. It is an attractive item, however.

#7: VicTsing 300ml Diffuser/Humidifier

VicTsing 400ml Aromatherapy Essential Oil Diffuser, Ultrasonic Cool Mist Humidifier with Wood Grain...

With a choice of three color options – light wood, dark wood, and dark cherry – this unit is designed to blend in perfectly whatever your personal style or décor.

The VicTsing is a large capacity diffuser in a compact design – it will sit neatly on a desktop whilst covering a large area with a pleasing, refreshing scent.

Although it is marketed as a diffuser/humidifier, the humidifier function is not particularly good.

Pros:

  • Large capacity in a compact design
  • Affordable

Cons:

  • Humidifier function is poor
  • No auto shut-off feature

Value For Money?

This is an excellent price, large capacity, stylish diffuser. As long as you’re not bothered about the humidifier function, this is certainly a purchase to consider.

#6: UrPower 300ml Ultrasonic

URPOWER 2nd Generation 300ml Aroma Essential Oil Diffuser Ultrasonic Air Humidifier with AUTO Shut...

Using ultrasonic waves to break down the scent particles in essential oils, this diffuser is one of the cheapest on the market. It offers the option of intermittent or continuous mist settings and a seven color light display.

It does have some drawbacks, most notably that it is prone to leakage. Also, even when the light display is turned off, there is residual glow which can be disruptive for those looking to use the diffuser while they sleep.

It also doesn’t offer particularly good scent coverage.

Pros:

  • Very affordable diffuser

Cons:

  • Prone to leakage
  • Residual glow can be disruptive, especially if using whilst sleeping
  • Prone to leakage

Value For Money?

While the price might excite some people, this diffuser is proof of the saying that “you get what you pay for.”

There are far better diffusers on the market for only a few dollars more.

#5: ASAKUKI 500ml Ultrasonic

ASAKUKI 500ml Premium, Essential Oil Diffuser, 5 In 1 Ultrasonic Aromatherapy Fragrant Oil Vaporizer...

The ASAKUKI 500ml diffuser is a great choice if you want large amounts of steam for a longer period of time. It’s also ideal for bigger rooms and spaces.

If filled to capacity, it can last for 10 hours when used in strong mist setting and 16 hours if you only have it on weak mist.

Many repeat buyers of diffusers, especially this brand, find themselves buying for their children’s rooms.

The auto-switch feature is very reassuring as it will turn off on its own if it ever runs out of water or overheats.

On the style front, it is not as stylish as other models but the LED lights when lit are particularly entertaining to children.

Pros:

  • Medium size and capacity
  • Doubles as a humidifer
  • With other bells and whistles like LED lights and timers
  • Auto safety switch
  • Easy to clean
  • With 12 months warranty

Cons:

  • Plug is at the bottom of the stand making refilling awkward
  • Not as much mist coming out as the 700ml version

Value For Money?

Overall, the bigger size and capacity is a win for this diffuser. If you have the budget though and you have a big room, we recommend checking out the 700ml model.

#4: UrPower 500ml Ultrasonic

URPOWER 500ml Aromatherapy Essential Oil Diffuser Humidifier Room Decor Lighting with 4 Timer...

With a 500ml capacity, this diffuser offers 3-in-1 functionality, serving as a diffuser, a night light, and a humidifier. It is important to note that the manufacturer states that this unit requires weekly cleaning.

With four timer settings and an auto shut-off feature, this is a diffuser you really can “set and forget.”

Unfortunately, there has been little effort made on the design front, and, when not in use, the unit doesn’t look particularly attractive.

This is unfortunate, especially when there are stylish, albeit smaller, diffusers available more cheaply.

Pros:

  • Large reservoir
  • 4 timer settings
  • Auto shut-off

Cons:

  • Not particularly attractive when not in use

Value For Money?

This would be a good option for those looking to use a diffuser to help them get a good night’s sleep, as, on the right setting, it offers a ten-hour run time.

People looking for a diffuser to use in public areas of the home may prefer a smaller but more stylish choice.

#3: TaoTronics 300ml Diffuser

Diffusers for Essential Oils, TaoTronics 300ml Ultrasonic Humidifiers with Wood Grain, Cool Mist...

This is a large stylish unit, with the capacity to offer a pleasant aroma across larger rooms.

It features a cool mist stream and seven colors of light display together with an auto shut-off feature for safety and peace of mind.

Because the mist stream can’t be adjusted, the mist, if used regularly and for prolonged periods, can encourage the buildup of mold in smaller areas.

Also, the buttons on the unit are somewhat awkward to operate and the lid of the diffuser does not fit flush.

Pros:

  • Large capacity
  • Auto shut-off feature

Cons:

  • Potential issues of mold caused by mist stream
  • Buttons awkward to use
  • Lid doesn’t fit flush

Value For Money?

While this is a very affordable diffuser, especially for a larger capacity option, it does have a lot of drawbacks which are worth bearing in mind before making a purchase.

It is also definitely much better suited to larger rooms and open spaces.

With an option of a light or dark wood effect color choice, this diffuser is designed to complement any décor.

Offering an adjustable mist output, and a cycle of seven colored lights, this diffuser has something to suit every preference.

Pros:

  • Good for small rooms
  • Choice of colors
  • Responsive customer support

Cons:

  • Difficult to operate

Value For Money?

This diffuser is in the mid-range, price-wise, and the option of a light or dark unit color may sway some people to purchase this over others.

#1: UrPower 100ml 2nd Gen

URPOWER 2nd Version Essential Oil Diffuser,Aroma Essential Oil Cool Mist Humidifier with Adjustable...

If you are looking for a good diffuser for a small room, we recommend this UrPower model. I liked it so much that I wrote a detailed review and bought a second one.

It still has all the strengths of the original version but this 2nd version comes with more mist, a measuring cup to make sure you add the right amount of water, and an auto-shut off feature for safety and peace of mind.

The UrPower is a crowd favorite mainly for two things.

The first is the convenience of the two diffuse settings. It can be set to green, which will alternately turn it on and off for 30 seconds each, and red, which will make it run continuously until it runs out of water or is shut off.

The green setting is particularly convenient for night time and when you wake up, it will still be doing its job.

The second is that it operates quietly. This is ideal for night time use and for light sleepers.

A common complaint with this model though is that it is tricky to open.

This is Amazon’s Choice for best diffusers for essential oils.

Pros:

  • Good for small rooms
  • Diffuse settings are convenient
  • Easy to use
  • Quiet
  • Auto shut-off feature
  • LED lights are actually pretty

Cons:

  • Difficult to open
  • The button light indicators can be bothersome at night if you want full darkness
  • Some reported reliability issues (which we didn’t experience)

A good basic diffuser for smaller rooms at a very good price. If you have a big space though, check out our recommendation below.

Best Essential Oil Diffuser For Large Spaces

If you have a big room or high vaulted ceilings, then you need an essential oil diffuser for large spaces. A single 100ml diffuser won’t do in this situation.

#1 Pick: UrPower 1000ml Ultrasonic

URPOWER 1000ml Essential Oil Diffuser Humidifiers Remote Control Ultrasonic Aromatherapy Diffusers...

It probably comes as no surprise but everybody’s pick (not just ours!) for big space use also comes from UrPower.

For roughly a ten dollar bump, you get cool features like a wireless remote and a water tank that’s 10x bigger.

One big difference between the 100ml versus the 1000ml version are the mist settings. The UrPower with the smaller 100ml water reservoir has settings for either continuous or intermittent mist.

In the bigger 1000ml version though, the settings are for high mist or low mist mode. So whereas the first has settings for intervals, the large version has settings for how much mist you want diffused.

With such a large amount of water in its water tank, it can run up to 15 hours on high mist mode and 20 hours on low mist mode.

It is Amazon’s Pick for large diffusers for essential oils.

Pros:

  • Ideal for big spaces
  • Ideal for users who want their diffusers running for long periods of time; can run on high mist mode for 10-15 hours and on low mist mode, 15-20 hours
  • Very quiet
  • Auto shut-off feature when the water rank nears empty

Cons:

  • May be difficult to open or close
  • If you like total darkness at night, the green light that indicates it’s on will bother you

What is an Aromatherapy Essential Oil Diffuser?

If you’ve ever been to a spa, you’ll know that one of the things that spas or massage rooms have in common is soothing music and scents. The latter is associated with aromatherapy, the practice of creating a particular mood or feeling – relaxation, peacefulness, joy – through the use of scents.

These scents are usually provided by quality essential oils from plants such as lavender and eucalyptus, fruits such as orange and lemon, trees such as sandalwood and cedar wood, and even spices like cinnamon and clove.

An aromatherapy essential oil diffuser combines these essential oils with water to create a fine mist which causes the chosen aroma to spread and linger, pleasingly, throughout a given area. Many diffusers also have colored lights to provide an additional level of relaxing stimulation.

Who Would Benefit from One?

Anyone who is sensitive to scents and who respond to pleasing smells would benefit from an essential oil diffuser. In the home, it combats the smell of lingering food, smelly laundry, and sweaty teenagers.

It provides a fresh, clean scent throughout the home, and even has the surprising benefit of helping children fall asleep more easily. Yes, even the fussy ones!

Adults and elders who experience trouble sleeping find that using an essential oil diffuser with an oil such as lavender overnight can help them drift off comfortably.

Diffusers are also useful in office spaces, waiting rooms, and consulting areas.

Things to Bear in Mind

  • Some people are more sensitive to essential oils than others. If you start to feel nauseous, or experience headaches when using a diffuser, it may simply be that you need to decrease the amount of essential oil you’ve used. Use fewer drops and see if it helps. If it doesn’t stop your symptoms, you may have to discontinue its use entirely.
  • You should only use natural essential oils as those that involve chemicals can cause damage to the inside of the diffuser. The chemicals involved can also trigger sensitivities.
  • When using a diffuser, the less water you use, the more mist is created. (I know – this seems counter-intuitive, but it is the case!)
  • Consider the size of the area you want to use the diffuser in: for a larger area, you’ll want to make sure you select a diffuser with a bigger reservoir.
  • As much as possible, try to get a diffuser that has an auto-shut off feature – it’ll shut down on its own when the reservoir empties.
