An effort to make safe drinking water available to everyone. A wearable water purification device in the form of a bracelet. It purifies water for safe drinking in developing countries, where clean water supply levels are low. Droplet is designed for anyone to wear around one’s wrist. It contains a UV purifying light bulb that when placed in a container of collected water, the UV light emitted kills contaminants and disease-causing bacteria in minutes. Droplet is also data driven to help prevent future water-related issues by saving information about water contaminants, bacteria, amounts of water consumed, and location of where a specific water was collected. Droplet is worn on one’s wrist. It can be used individually or shared between multiple people or within a family.
