The Tom Dixon Scent Elements Diffuser - Air is part of a series inspired by the medieval quest to reduce matter into 4 essential elements. Here, the aromatic palette is a suitably light and crisp floral, with distinctive notes of honey sweet Neroli, pink pepper and orange flower. When placed within the mouth-blown glass flask, a stick of British-sourced charcoal gently diffuses the liquid scent for up to 10 weeks.
