Maifan stone helps reduce bacteria, impurities, residual chlorine, and heavy metals in tap water. It also offers antioxidant properties that may help restore skin balance and reduce excess oil secretion to rejuvenate the skin. Zeolite is a natural crystalline material that helps remove fluoride and various heavy metals while allowing beneficial minerals to remain in the water. It contains minerals that are easily absorbed by the skin. Negative ion balls help increase water alkalinity (pH) by releasing negative ions, which can ionize water and adjust its pH to slightly alkaline. This process may help reduce scale buildup, improve hair smoothness and shine, and support softer, more balanced skin. This filtered shower system includes three types of mineral stones in two sizes, allowing customizable combinations. Designed as an ionic filter shower head, it offers a simple replacement for standard shower filters with bio-active mineral elements. Guarantee: We value every customers shopping experience.
