2.2 billion people don’t have access to safe drinking water. They get their water from unsafe sources such as springs, wells, or water posts and store it in hazardous containers – increasing the risk of contamination.

This results in increased illnesses such as diarrhea, cholera, typhoid, which results in increased medical expenses as well as sickness and death.

Today attempts to clean the water are done through boiling on indoor stoves that use coal or wood, causing severe health issues. Further, this also contributes to deforestation.

SolarSack is a household water purification system that is easy to use and can provide safe drinking water for two people for a full year. It kills harmful bacteria and viruses, ensuring that the water is safe to drink.

Fill the sack, put it in the sun, and when the water is ready, an indicative smiley face will tell you when it’s ready to drink. You’ll have 4 liters of clean water in 4 hours. Simple and effective.

Each sack costs 2$ to produce, making it 30 times cheaper than charcoal. Exchanging the charcoal for a SolarSack also saves 500kg of CO2 and two trees.
