We looked at several different essential oil diffusers to help you choose one that would suit your needs. Our top choice is the Anjou 500ml Essential Oil Diffuser. The large capacity, quiet running and innovative essential oil reservoir made this a stand out. In addition to dispersing fragrance this also adds moisture to the air; perfect for dry winters.
Why use an essential oil diffuser?
People use them as part of their Aromatherapy regimen. Lavender is purported to help relieve stress and help to ease you into sleep. Peppermint is said to invigorate the mind with its bracing, clean scent.
They are wonderful to simply add fragrance to the air. Adding a scent to your environment can enhance your mood. Pick fragrances that you enjoy and see how even a subtle aroma can affect your frame of mind.
A diffuser turns essential oil into tiny droplets. They are dispersed into the air along with water vapor. There are several types of diffusers, we’ll be looking at the ones that work using ultrasonic sound.
An essential oil diffuser is a wonderful way to disperse the oils into the atmosphere. The essential oil floats on top of the water and gets turned to mist with the water by ultrasonic waves.
Benefits
Pure Fragrance
An ultrasonic diffuser does not alter the essential oils. Oils can be affected by heat. Diffusers vaporize the oils while leaving them in their pure state. They are distributed around the room with water vapor; clean and all natural.
No Residue
Unlike candles and incense, a diffuser does not create any waste or residue. No ashes to clean and no smoky remnants to build up. You get pure fragrance on a mist of water. Use your favorite essential oils.
Safety
There is no open flame to worry about. They automatically shut off if they run out of water. They can also be set to run for a predetermined time and then shut off.
Adds Moisture to the Air
All ultrasonic essential oil diffusers act as humidifiers to a degree. The larger ones can help add moisture to the air. The smaller ones don’t make much of a noticeable difference in humidity levels.
Lighting Displays
Most essential oil diffusers have lighting components. They are generally an option to be used if you like. They can be set to cycle through colors, or set to a color that you find relaxing. This can be helpful for people who can’t fall asleep in a completely dark room.
Our Choice
Our top choice is the Anjou 500ml Essential Oil Diffuser. We love the 500 ml capacity, it’s just right to run all day. The essential oil tube that slowly adds oil is a fantastic feature.
Here are the models that we had a look at:
- URPOWER 300ml Aroma Essential Oil Diffuser
- Himalayan Pink Salt Diffuser
- Anjou 500ml Essential Oil Diffuser
- ASAKUKI Smart Wi-Fi 700ml Essential Oil Diffuser
- Porseme 280ml Essential Oil Diffuser
URPOWER 300ml Aroma Essential Oil Diffuser
The Urpower is the most diminutive diffuser that we evaluated. It’s ideal for a small room. However, the 300 ml capacity means it will need to be refilled with water during the day. The manufacturer recommends this for a room up to 215 square feet. It has a timer for 1, 3, and 6 hours, but users report the water supply is depleted after 4-5 hours. The optional light can be set to 7 colors. This runs fairly quiet, but does beep when the water runs out. This one tends to run with more noise than others that we reviewed.
Pros:
Automatic shutoff when empty
Timer function
7 Color light
Easy to clean
Cons:
Smaller capacity
Not as quiet as others
Audible beep on shutoff
Himalayan Pink Salt Diffuser
The Himalayan salt diffuser has a 400 ml capacity. This makes it ideal for a medium size room. We like the clean lines and pod shape of this. Housed within a block of Himalayan pink salt, this diffuser adds a warm glow. The timer has 1, 3, 6 hour settings in addition to continuous mode. The optional light feature can cycle through 7 colors, or be set to a single color. It runs quiet, and is easy to clean. The remote control lets you turn the unit on or off and other functions.
Pros:
Intermittent setting
Automatic shutoff when empty
Timer function
Easy to clean
Quiet
Cons:
Mid size capacity
Needs to be refilled before 8 hours
Anjou 500ml Essential Oil Diffuser
The Anjou model is great for medium to large rooms. The 500 ml capacity can last 8-10 hours on high, and an impressive 10-15 hours on the low setting. This has an ingenious essential oil tube that slowly releases the oil for continuous scenting – up to 12 hours. The Anjou is one of the quietest models we tested. The timer has 1, 4, 8 hour settings in addition to continuous mode. The 7 colors can be cycled through, or set to a steady color, or turned off completely. This model is also easy to clean. People have reported that mist may collect around the unit.
Pros:

Automatic shutoff when empty
Timer function
7 Color light

ASAKUKI Smart Wi-Fi 700ml Essential Oil Diffuser
The Asakuki Smart Diffuser is Wi-Fi enabled. You can control this diffuser with an app on your phone. It is also compatible with Amazon’s Alexa smart home appliance. This diffuser has the largest capacity we tested. At 700 ml this diffuser will run for an impressive 14-16 hours, perfect for large sized rooms. The timer has 1, 3, 6 hour settings in addition to continuous mode. We were surprised that the timer did not include a longer time option considering the large water capacity. It does have an automatic shut off when the water does run out. This diffuser is also easy to clean, and runs relatively quiet. The 7 color lighting choices can cycle, or be set to one color. The Asakuki is also able to adjust the light from high to dim. People have reported that mist may collect around the unit. Some users initially had a difficult time connecting to Wi-Fi.

Porseme 280ml Essential Oil Diffuser
The Porseme has a handmade glass diffuser with a 3-D fireworks effect. It’s smaller capacity is ideal for a small room. The 280 ml capacity means it will need to be refilled with water during the day. It has a timer for 1, 3, and 5 hours. The optional light can be set to 7 colors. This runs fairly quiet. The glass diffuser is beautiful, but fragile. The coating on the diffuser is quite delicate, we recommend wiping it only with a dry cloth.
Pros:
Automatic shutoff when empty
Timer function
7 Color light
Striking 3-D effect
Cons:
Smaller capacity
Glass is fragile
