An electric diffuser comes in a variety of shapes, sizes and colors, so it's important to find one that will fit your needs. Some popular models include the Soothing Mist Diffuser, which comes with four different settings and the ultrasonic aroma diffuser, which uses high-frequency vibrations to create a more relaxing atmosphere. Before purchasing an electric aroma diffuser, it's important to consider your room size, desired mood and preferences. Some people prefer diffusers that are quiet while others prefer ones that produce more noise. Additionally, some people prefer diffusers that use heat or cold while others prefer them without any added features.
