Reusable water bottles are popular, but most don’t come with an integrated way to ensure water purity. My idea is to design a water bottle with a built-in filtration system that can adapt to different water qualities. The bottle would have a replaceable multi-layer filter, combining activated carbon, ceramic, and UV-C light sterilization. The user could adjust the filtration strength based on the water source—lighter for tap water and more robust for river or lake water when outdoors. This would be ideal for travelers, hikers, or people living in areas where water quality varies. The bottle could also include a built-in TDS (Total Dissolved Solids) meter, giving real-time feedback on the quality of the water being consumed. While the challenge would be keeping the filtration process efficient without reducing the flow rate, this solution could provide a portable and convenient way to access clean water anywhere, promoting sustainability by reducing reliance on single-use plastic bottles.
