This new diffuser from vitruvi is unique for a few reasons: It does not need water or heat. It uses cold air technology and easy scent cartridges (pick from a crisp, piney scent or an uplifting, citrusy one ) —these are for you if you find oils to be too messy or fussy. There’s no cleaning required. You just lock in a cartridge, turn it on, and even a large, open space will be gently scented from there. (For the power of the mist, you can choose from five different scent strengths.) Like other beloved vitruvi diffusers, this one has an elegant ceramic matte finish. 5.1 x 5.1 x 8 BPA free plastic, ceramic cover
