Unlike other diffusers, ultrasonic diffusers do not utilize heat to evaporate oils, which is why you can use any type of oil in them. This characteristic also makes them the safest to use in children’s rooms and provides the most effective therapeutic benefits as heat alters the chemistry of the oils that you’re diffusing.

These diffusers are unique in that they use electronic frequencies to disperse oil into the air instead of using heat.

The frequencies emitted by the diffuser create vibrations in the water, which are carried to the surface of the water where the essential oil floats. The oil is then vaporized by these vibrations and dispersed into the air.

As the essential oils in the water of the diffuser are broken down, they are released into the air along with natural ozone, which improves the quality of the air around you.

The scent remains in the air with the particles of oil for several hours.

As you can see, not all ultrasonic diffusers are created alike. The best ultrasonic diffuser is the one that will work best for you considering the space you want to use it in and various other aspects.

One thing is for sure though – whether you are drawn to the beautiful flower-shaped decorative diffusers, the basic portable diffusers, or the diffusers with loads of features and settings, they all provide the same set of benefits.

Every ultrasonic diffuser on our list will fill your room with the soothing scent of your favorite essential oil. They’re great for relaxation and meditation, or simply for purifying and deodorizing the air around you effectively.

They also all double as humidifiers, which makes each one ideal for dry air climates. The humidifying feature comes in really handy during winters when you have to keep the heat on full blast. It will also help relieve symptoms from colds and the flu and help keep your sinuses clear.

Ultrasonic diffusers are the ultimate aromatherapy devices with added features that no other diffuser can match.

We hope that this guide has provided you with all the information you need to choose the best one for you and your room.
