We have often been asked which diffuser is the best; but with so many different types of diffusers available (each with their benefits and downsides), the best answer we can give is—it depends on what you like in a diffuser. There are many different diffusers on the market today, so it is important to know the differences so you can choose one that will work best for you.
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.
