The Puressentiel Diffuse & Go Ultrashall diffuser ensures free breathing thanks to the vaporisation of pure essential oils. The micro-diffusion nebuliser has been developed with a blend of Ultrashall and atomisation and also includes an integrated colour change. With this new technology, it is possible to use the nebuliser without a cable. When the battery is fully charged, the nebuliser can be used for up to 40 hours in an energy-saving way.
