It can work up to 5 hours but it has a lower mist output, that is 20 ml/h. The auto shut-off function is a great addition as it helps prevent any unpleasant incidents that may occur when the water in the tank has finished. Unfortunately, it doesn’t have any time settings.
For a more user-friendly experience, you can choose between a continuous or intermittent mist (30 seconds on and 30 seconds off). Furthermore, you will surely enjoy the 7 LED lights which are very soothing. You can either choose a certain color or you can set the unit to automatically change them after a preset time.

As you can probably guess, the larger capacity, the less frequently you will have to add water in the tank. This also means you will have more time to enjoy the scent in your room until the unit remains with no water. There are many oil diffusers that can hold 100 ml, but we also chose some models that are more convenient from this point of view. Therefore, the VicTsing Aroma Essential Oil Diffuser and the Urpower Dark Wood Grain Essential Oil Diffuser come with a tank capacity of 300, respectively 200 ml. Of course, there are models that can hold more water, but this automatically means a larger and heavier unit. A diffuser with a larger tank can diffuse water for more time, but this doesn’t necessarily make it appropriate for larger rooms.
The working time or operating time refers to the period of time the unit can work without having to add more water. The operating time differs from model to model, so you can find units that work for 3 or 4 hours and units that work for 9 or 10 hours. If you take a look at our comparison chart, you will see that the VicTsing Aroma Essential Oil Diffuser features the longest working time, that is 10 hours. This makes it very convenient as you won’t have to add water too often. The other models can operate up to maximum 5 or 6 hours, depending on the mist output.
All our models come with the auto shut-off function and for good reason. This feature prevents the unit from burning out when there’s no water left in the tank. Even if you let the device on during the night and the water runs out, you can be sure you will be safe, so there’s nothing to worry about. Safety is very important for many manufacturers and most of them consider this feature necessary for a risk-free operation.
The mist rate represents the quantity of water the unit delivers during an hour. The quantity is measured in milliliters per hour and the more mist output the unit releases, the more scented the room will be. In general, a unit which delivers more mist is recommended for larger rooms, such as the Urpower Dark Wood Grain Essential Oil Diffuser. In high mist mode, this unit has a mist output of 70 ml/h. The model with the lowest mist is the Aromatherapy Essential Oil Diffuser, being suitable for small rooms. Some units allow you to select the quantity of mist you want to be released or to set the unit to release the mist at certain intervals of time (e.g. once per hour, once per two hours, etc.).
Most of the available diffusers come with built-in lights. The lights can be used as entertainment, to boost your mood, or as night lights. The number of lights differs from one model to another, but all the products selected by us feature the same number, that is 7 lights. For more convenience, you have the possibility to stop the lights at one color or to set them to change automatically. Additionally, you can also opt to run the unit without any lights.
Each model presented in the table comparison chart uses ultrasonic technology to diffuse the water. In comparison to other available diffusers, they don’t use heat when producing the vapors. When it comes to essential oils, it was discovered that the heat has a negative impact on their composition and properties. So, instead of heat, the ultrasonic oil diffusers use vibrations that don’t damage the essential oils. The ultrasonic diffusers use electronic frequencies to make these vibrations, being measured in MHZ (megahertz). One MHZ represents one million hertz or one million cycles per second. As you can see, 4 of our selected models use an ultrasonic rate of 2.4 MHZ and only one, the Coosa Aromatherapy Essential Oil Diffuser uses an ultrasonic rate of 3 MHZ.
