When water comes in contact with the media filaments inside the Bathball's fabric pouch, the chlorine ions in the water are converted into harmless zinc chloride. The toxic effects of chlorine, chloramine, and chlorine gas are eliminated with the aid of KDF Formula 73. More chlorine is removed faster if there is adequate circulation of the Crystal Ball in the water. The quartz crystals mixed with the media reduce the molecular structure of water into smaller clusters, thereby allowing enhanced sudsing and lathering of soap.
