We are often asked by people which diffuser is the best. Unfortunately, with so many different types of diffusers available (each with its benefits and downsides), we've found that the only way we can answer that question is—it depends on what you like in a diffuser.
There are four different categories of diffusers available on the market today. Each of these types of diffusers differs in the way that it puts essential oils into the air, and each has different benefits. These four categories include: nebulizing diffusers, ultrasonic or humidifying diffusers, evaporative diffusers, and heat diffusers.
