As soon as you turn it on, it pretty much lets you escape from the daily stress and buzz of city life into a more relaxed and calm zone. The whisper quiet ultrasonic vibrations within convert the oil and water into a scented mist. It is no wonder it is a highly rated bestseller in its category.

It features a multi-color LED light that cycles through 14 different colors to add onto the relaxing ambience as it mists up the room. This light can of course be switched off independently or set to your favorite color. The faux wood finish has been done elegantly and looks classy as opposed to tacky.

2. Deneve Riverock

deneve riverock

Deneve Riverock Essential Oil Diffuser

The Deneve Riverock has an unique appeal to its presence and function thereby making it one of the most desirable diffusers for aromatherapy.

It obviously was designed to look like a river-sculpted pebble with its smooth rounded shape. I like to think they wanted to have a similarly relaxing effect with this diffuser and they seem to have achieved the effect they were going after. The Riverock if highly rated by thousands of satisfied buyers, and all in a very affordable package.

The Riverock is available in black or white and its coverage extends to an area of 250 square feet. That’s a relatively larger room so it can suit most living rooms. It has an auto shut off mode so you don’t have to worry about it burning your house down after the essential oils are used up.

The best aspect of the Riverock is that it is cheap as far as diffuser prices go. This guarantees you essential oil aromatherapy without having to break the bank. This would be ideal for beginners who are just dipping their feet into the world of essential oils and aromatherapy. This way you can test if it works for you inexpensively.

  • Very affordable
  • The LED band isn’t too bright and can be left on at night
  • It has a simple but effective design with one button to control functions
  • It is quiet in operation
  • It has a small time-frame of 5 hours as compared to other diffusers.
  • It has a shallow tank reducing the depth and increasing chances of water to spill out.
  • Available in less variety of shades.


3. GreenAir Spa Vapor

GreenAir Spa Vapor

GreenAir Spa Vapor

This diffuser is one of the most readily available and handy product.

It is another affordable essential oil diffuser that won’t make a huge dent on your pocket.

The Spa Vapor boasts a coverage of up to 400 square feet which is a medium to large living room. The effect may be too much for some in a bedroom setting. Of course, your mileage will vary.

This diffuser has a large tank which ensures continues freshening action for 8 hour before needing a refill. So you can let it run all night as you fight that cold. Or you can alternatively place it in your office for all day freshness.

Another brilliant feature of this diffuser is that it is resistant to corrosion from citrus-based essential oils. This is a unique advantage over most diffusers that cannot handle citrus and thus out of the box this diffuser proves to be more versatile than most.

The lighting fixture changes color every few seconds or just lights up a solid color continuously. This can of course also be turned of, to allow you to sleep for example.

  • It has various lighting display options
  • Very affordable and widely available
  • Lightweight and portable
  • Is not quiet in operation
  • Comes with extra parts which can be easily misplaced




4. Koko Aroma ZenMist Essential Oil Diffuser

Koko Aroma ZenMist

ZenMist Oil Difusser from Koko Aroma

The ZenMist by Koko Aroma is an excellent ultrasonic oil diffuser.

It comes with a 350ml capacity that gives you up to 12 hours of continuous misting action. This will give you all day guaranteed freshness.

Since it’s an ultrasonic diffuser, it lets off cool steam which adds to the refreshing qualities of the essential oils. It is also whisper quiet and you will be hard pressed to tell when it’s operating just from the sound. It comes with an LED lighting function which can rotate between seven colors, one continuous color or be switched off completely.

This unit has a mild misting function. So it’s the best unit if you want a subtle effect, not so much if you want a more obvious misting action. The lid of the unit my also need a redesign. It comes off easily as you handle the unit even when you’re doing something different. So if you’re the type that values such small touches, it may be better to seek  different unit.

  • Small size and very portable (good for traveling with)
  • Can double up as a simple humidifier without essential oils
  • It’s mild misting is perfect for those seeking a subtle effect
  • Extremely quiet in operation


  • Has a flimsy lid which may annoy some
  • Refilling requires extra care not to spill


5. Smiley Daisy “Love in a Mist” Diffuser

Love in a mist

Smiley Daisy’s beautiful Love in a Mist oil diffuser

This is the most unique of the diffusers we have had a chance to review.

It comes with a uniquely crafted porcelain outer cover with beautiful floral designs. When you turn on the light, it shines through the designs and casts light patterns which we absolutely loved. It options of two colors which are Sapphire Blue and Ruby Red. This unit would be perfect if you prefer a unit with ‘character’ as opposed to the sterile looking plastic or faux-wood diffusers that dominate the market.

The unit is an ultrasonic diffuser, meaning cool mist and low noise. It is a small diffuser and doesn’t have a long operation time (4-6 hours). It’s LED lights, like many others, have the options of cycling between different colors, one solid color or simply off.

The unit is slightly more expensive than many of the diffusers we have looked at but the quality its design and materials show its worth. It has an aluminum base, high grade plastic interiors and the aforementioned porcelain outer cover. The power adapter also works with voltages from 110v to 240v. It can therefore also work in countries that use different voltages from the USA.

Word of caution though. Poor vent placement means that internal circuits are exposed to the unit’s mist. This means that they corrode easily making the unit stop working. This can be mitigated by opening up the unit and insulating the circuitry.

  • Unique design that stands out from the pack
  • Continuous and intermittent modes for longer operation
  • Highly responsive customer care
  • It is off course fragile due to the porcelain sleeve
  • Design flaw makes it corrode easily



6. Sztrokia Aromatherapy Oil Diffuser

Sztrokia oil diffuser

Sztrokia oil diffuser with 3D starburst effect

This one product surely knows how to catch attention with additional and attractive features.

Just like the Smiley Daisy, this diffuser breaks away from the bland appearances of ordinary oil diffusers. It features a 3D starburst effect that looks awesome when its LED lights are switched on. If you like patterned lighting, you will love this diffuser.

The LED lighting, as is becoming standard, can cycle between 8 different colors, one solid color or be switched off completely. It also has 3 brightness settings; LOW, MEDIUM and HIGH. We felt this was an exceptionally nice touch.

It is an ultrasonic diffuser so expect  cool mist and quiet operation. It has a capacity of 180ml and runs for up to 10hrs on a full tank. It has auto shut off feature and options for timers. You also get options for mist modes. Strong for heavy misting and light for a more subtle effect.


  • Beautiful light show
  • Adequate running time
  • Gives good options in terms of light brightness and mist amount
  • Can be used as low level humidifier
  • Good for people looking for a smaller diffuser
  • Fragile due to glass outer cover


7. doTERRA Petal Diffuser

doterra petal

The DoTERRA Petal essential oil diffuser

doTERRA is a name that will forever be associated with essential oils.

They are among the biggest manufacturers of essential oils, if not the biggest. So it only makes sense that they would make an oil diffuser for us to use with their wonderful oils. So how does the Petal hold up?

The doTERRA Petal has a simple design that emphasizes ease of use. It’s very compact and can be used at home or in the office. It features a timer for 1, 2 or 4 hour operation. The Petal has a smaller capacity (150ml) so is not suited for all-day or all-night continuous use. You will have to refill it at least once. It has a coverage area of approximately 300 square feet.

The doTERRA Petal also features an LED light that lights up the entire top portion of the diffuser. This light can be dimmed to your preferred level. However, it cannot be completely switched off. This feature can be put to use as a night light. If you’re the type that needs total darkness to sleep then this wouldn’t be a good fit for your bedroom.


  • It is a compact product as compared to few diffusers out there.
  • The diffuser has a nice soft white light and acts as a legitimate light source as well.
  • It is again quiet and silent in its operation.
  • Simple design makes it easy to use
  • Assured to work well with doTERRA essential oils
  • It has a single white light option and doesn’t have color changing varieties like most of the diffusers in the market.
  • It has a relatively low time frame of 4 hours.
  • Considerably higher priced compared to similar diffusers


8. PureSpa Compact Diffuser

purespa diffuser

The PureSpa compact ultrasonic aromatherapy diffuser with Ionizer and color-changing light

From personal care product company Pure Enrichment, comes the highly capable PureSpa Compact Diffuser.

This diffuser has been popular among users ever since its debut approximately three years ago. This is proven by thousands of five-star reviews on sites like Amazon.

The PureSpa features a 100ml capacity which translates to 3-5 hours operation. This of course means it’s not suitable if you need an all-day or all-night diffuser. However, in that short time period it does a perfect job in ensuring a soothing atmosphere for your home or office. Being a compact diffuser, it is rated for small rooms of up to 250 square feet.

The PureSpa also features an LED light which bathes the room with a soft ambient light. This light rotates through different colors which gives it an interesting effect. Unfortunately this light cannot be set to just one color and either has to rotate through all the colors or be turned off.

This unit includes an ionizer which purifies the air of allergens. This makes it perfect for people suffering from allergies. You should be aware, however, that ionizers convert oxygen to ozone which is a pollutant. The ionizer should therefore not be run for too long.

  • It is cheap, easily available but at the same time it is made up of durable materials.
  • Gives a choice of 5 colors
  • It occupies less space and is easily portable.
  • It is very easy to understand and operate due to simple design
  • The cycling of the light colors may be annoying for some.
  • The small coverage area limits its use to smaller households


9. Lauco 450mL Cool Mist Ultrasonic Humidifier/Diffuser

lauco diffuser

Lauco 450ml Ultrasonic Humidifier and Diffuser

If you wish to experience an amazing combination of essential oils and music together then this is certainly your choice of diffuser.

As much as music can heal wounds of all kinds and much before time can do so, imagine what the result would be when its creatively combined with edible oil fragrances. Its a treat to all our senses, refreshing them instantly and charging them up in no time.

The Lauco is the poster child for multitasking. It doubles up as a Bluetooth speaker, LED lamp, essential oil diffuser and humidifier. It features a Bluetooth 4.0 connection to enable you to play audio from your phone, computer and other Bluetooth-enabled devices. So you have the option of playing soothing sounds as you enjoy its aromatherapy mist.

The Lauco also has the distinction among the diffusers on our list of having the ability to be controlled via app. It comes with an Android/iOS app that acts as a remote control to control the light changes and audio controls.

  • It is available in 7 mood changing colors to suit the atmosphere. It has both bright and dim mode as per one’s choice.
  • Controllable via mobile app
  • It has easy and simple functions.
  • It can run for 8-10 hours
  • Also, one can play music for about 8-10 hours and relax while enjoying both the music and the fresh aromas.
  • It is a little bulky which might not suit some.
  • The egg shape mean care must be taken to avoid spilling of oils or water.
  • Being a jack of all trades makes it a master of none. The speaker quality for example, suffers as a result


10. ZAQ Allay Essential Oil Diffuser

ZAQ Allay diffuser

ZAQ Allay LiteMist Ultrasonic Aromatherapy with Ionizer Essential Oil Diffuser

The ZAQ Allay is another evergreen favorite.

It’s a durable oil diffuser that simply does its main function effectively. It is no wonder it has amassed thousands of five-star reviews on Amazon with very few complaints of broken units after a couple of months.

As with nearly all diffusers, it features a soft LED light which can act as a night light. The top section comes in 4 different color options of blue, orange, pink or white.

The diffuser section is highly effective. However, since it’s a medium sized diffuser it is rated for rooms up to 300 square feet in size. This is a typical bedroom or medium sized living room.

This unit comes with a capacity of 80ml. This translates to vapor action of up to 4 hours. So it is not a good all-night diffuser. It comes with an auto-shutoff function for when the water runs out so you don’t have to worry about it burning up in case you forget it.

The ZAQ Allay keeps it simple and doesn’t come laden with lots of unnecessary extras. It’s a diffuser first and foremost and does this function exceptionally well. You can be assured that with an Allay you will have consistent vapor distribution for many years to come.

  • It is easy in operation and simple in design.
  • It is highly durable and will last you years
  • Very quiet
  • Cheap and affordable but high quality
  • Effective diffusion means you need less oils


  • Not suitable for larger rooms
  • Runs for a shorter time than other diffusers


Buying guide – Best essential oil diffusers of 2019

Oil Diffusers are gaining huge popularity in this rapidly progressing world due to their health benefits, as a major source of ambience and decor with them being the focal point and obviously as insect repellents.

Oil diffusers introduce you to the concept of natural living with the help of natural scents around that are both beneficial for health and ambience friendly. Of course after a busy day at work they do help you release your stress. But that’s just not the only thing they do. They instantly have the ability to escalate your mood. Whether its an office meeting or a peppy party with friends or a quiet pleasant family get-together, they energize your mood and help create a positive atmosphere around.

But with such a wide spectrum of oil diffusers all over the place, how can we pick the best oil diffusers for your use?

Heat diffusion versus cold misting

Some diffusers work by evaporating the essential oil mixture into vapor, much like boiling a liquid. The vapor then spreads round the room as warm mist. However, the problem with this approach is that the heat affects the potency of the essential oils. In some cases even, it can lead to harmful by-products. So avoid heat diffusers as much as possible.

Nebulizing versus ultrasonic diffusers

Of the cold mist diffusers, you have 2 broad categories with a little bit of overlap. Nebulizers turn the essential oil mixture into an aerosol mist, usually using compressed air. This releases a quick jet of essential oils in the form of tiny droplets that spreads into a fine mist. Ultrasonic diffusers on the other hand turn the essential oil using a rapidly vibrating baseplate. These vibrations are minute and of a higher frequency that most most people can’t hear thus giving the impression of quiet operation. Our preference is for ultrasonic diffusers for the quiet operation and generally cheaper price. Nebulizer ultrasonic diffusers also exist but they tend to be more expensive.

Extra considerations

Apart from the essential guts of the diffuser, there are other individual considerations and preferences that will vary among users. This will of course include things like aesthetics, coverage area, running time, size and portability among others. You should ideally list the reasons why you need a diffuser before you start shopping around for one. This will help you weed out unsuitable units much faster.


Final Thoughts

These were the Top 10 Best Essential Oil Diffusers available in the market in various range and a spectrum of varieties.

They are desirable, they are soothing, they are relaxing and they undoubtedly are your source of peace and happiness at all times. Be it your slumber at house, or a nice peppy party place, or a quiet corporate office environment, they truly serve as your best friend and help you relax yourself while inhaling beautiful scents that have mood changing and medicinal properties within them.

Do try them. Each one of them have an unique appeal to them and you never know which one shall suit you best. They are multi-functional in their use and can be used to their full potential. After a tiresome day at work, who in the right mind wouldn’t wish to come back home and be greeted with this trending and beneficial aromatherapy. Long Live the Scents!
