Füm is an all-natural non-electronic wooden essential oil inhaler that doesn’t vaporize or change the state of the essential oils when you inhale. Therapeutic grade essential oils are infused on a pure therapeutic grade polyester insert called a Core, then placed into the end of a Füm. By breathing in on the mouthpiece and out through your nose, your olfactory system in your nasal cavity sends signals directly to your brain and body to release the natural benefits of essential oil much quicker and more naturally than other methods like vaporizing essential oils in a large room with a diffuser.
