How does the cotton balls help clean water?

Cotton balls can help clean water by acting as a natural filter that traps impurities and contaminants. When water is passed through cotton, the fibers capture particles such as dirt, sediments, and some microorganisms. This simple filtration method can improve water clarity and reduce certain pollutants, making it safer for drinking or other uses. However, it's worth noting that cotton balls are not a substitute for more advanced water purification methods.
