CLEAN : Students develop cheap lead filter to bring clean water for everyone

The video discusses a course developed to create a simple and inexpensive filter to remove lead from water. It highlights the challenges faced, such as calcium filtration, and explores innovative designs using 3D printing. The course emphasizes practical skills over traditional testing, leading to student achievements recognized at conferences. The filter design is versatile, capable of removing various toxins, and is particularly useful in disaster scenarios. The instructor expresses pride in the students' work, which is comparable to graduate-level research.
