PURE is a 2-in-1 electric oral care kit that inherits Dyson's sustainability philosophy for long-lasting durability. PURE integrates an electric toothbrush and a water flosser to meet the needs of a wide range of users, simplifying operation and saving space. PURE has a removable toothbrush sterilization case for travelers. The toothbrush handle switches between toothbrush or water flosser modes by recognizing module replacements. A built-in airflow fan prevents moisture contamination of the brush head and avoids psychological discomfort.
