The laundry ball is made of eco-friendly TPR plastic and filled with 3 types of ceramic beads. The beads can remove chlorine from water, kill bacteria, odor, and mold. It can increase the pH level above 7, where it can bring water to a better condition to clean clothes. Also, with negative ions and without infrared beads, it cleans clothes equally well or even better than any market detergent, without any chemical substances!
