Aromatherapy Diffusers

When I was looking for my very first aromatherapy diffuser, there were several to choose from but no direction in which diffuser to choose.  Once I had purchased multiple diffusers, I was determined to put together a guide for others to follow to ensure you buy the right diffuser for you.

BELOW you will find my Aromatherapy Diffuser Reviews and Selection Guide which were created to make it as easy as possible for you to determine which would be the best aroma diffuser for you.  There’s a lot to learn about diffusers and it’s not only easy to get lost in selecting one, it’s also easy to buy one that you’re not happy with.

Not only are there four different types of aromatherapy diffusers, but it’s important the to note the differences in them, how they work, the sound level, etc.

The four types of essential oil diffusers:

  • Ultrasonic
  • Evaporative
  • Nebulizing
  • Heat

The most important variables in diffusers are:

  • Aroma Coverage
  • Therapuetic Value
  • Ease of Use
  • Noise Level
  • Appearance – while appearance isn’t that important to the results, you might care how it looks in your home :)

On this guide you will find multiple columns to help you make your buying decision.

So, which type of aromatherapy diffuser is the best for you? This is where this page comes in handy. I have built a review of each diffuser and rated the most important aspects of each diffuser and applied that to a rating system. The result of this is the most comprehensive rating system of diffusers I’ve personally seen. I only wish this were available when I first began..
