PotaVida's Smart Solar Purifier consists of a 10 liter hydration bag with an electronic dosage indicator that shows when the water is safe to drink and records usage data. Our technology uses the process of solar disinfection (SODIS) to reduce the cost of water treatment and eliminate the need for replacing filters and chemicals. Each batch of water is ready in about 5 hours in sunny conditions, or up to 2 days during the rainy season. Our product has a shelf life of 5 years and design lifetime of 1 year, making it an ideal disaster relief supply. To use, simply fill the bag with water, place it in the sun, push a button, and wait for the indicator's green LED to show that the water is safe.
