Did you know that over 2 billion people worldwide don’t have access to clean drinking water? Contaminated water causes diseases like cholera, dysentery, and hepatitis, which kill thousands of people every year—many of them children.

How Did We Test It? Simulated contaminated water (using dirt, food coloring, and small debris) was poured through the filter. Water quality was assessed before and after filtration based on clarity, odor, and physical debris removal. Specific metrics such as turbidity levels (using a turbidity meter) and odor intensity were recorded. Photos were taken to visually compare the effectiveness of the filtration system, and additional tests were conducted to measure the filter’s durability over repeated use. Simulated contaminated water (using dirt, food coloring, and small debris) was poured through the filter. Water quality was assessed before and after filtration based on clarity, odor, and physical debris removal.

Key Observations:

• Turbidity: Significant reduction in cloudiness.
• Odor: Improved taste and smell after charcoal filtration.
• Debris Removal: Large and small particles successfully filtered out.

The "Filtering the Future" project demonstrates that clean water can be made accessible through innovative, low-cost filtration systems that leverage simple materials and scientific principles. By combining natural filtration methods with modern techniques, this system offers a practical and scalable solution for improving water quality in communities with limited access to safe drinking water.

Our testing showed clear improvements in water clarity, odor, and safety, confirming that the filtration system is effective at removing a wide range of contaminants. The system’s ability to significantly reduce turbidity and improve water quality highlights its potential as a reliable and affordable solution.

This project supports global efforts to address water scarcity and improve public health, demonstrating that affordable innovations can make a significant impact. With further refinement, the system could help provide clean water to communities worldwide.
