Unknown or Phantosmia is the most intriguing home fragrance in the world. This home scent diffuser is itself an olfactory hallucination. It cannot be characterized by one or two aromas. The molecules of its perfume in the air are perceived differently by each person in your living room, according to the memories that are being rooted in your soul. Phantosmia’s fragrance is based around a feeling, a memory or an emotion.

Scent, emotion, and memory are intertwined. All due to the anatomical connection from the nose to the brain. One of the world’s most unexplainable phenomena, the smell, is also one of the strongest senses in influencing our attitudes.

Inhale. Hold your breath. What does Phantosmia smell like to you?
