Filter water naturally! The pink ceramic beads EM® reactivate and restructure the water in a natural way to restore it to its original healthy and living state. Thanks to these beads, remove limestone, chlorine and impurities from tap water. Simply drop in your ceramic beads to keep your water clean longer. Pink ceramic beads have a more porous texture than gray beads, which adds mechanical filtration by adsorption and therefore improves their filtering power. The taste of water after filtration may seem strong to some people. It is possible to mix them with gray pearls to have a more neutral taste. Before first use, it is recommended to boil them for 15 minutes and let them dry in a dry place. Beads are sold in bulk (without packaging) by 100 units in a biodegradable bag. Original product from the work of Professor Teruo Higa Durability: 6 months. To be renewed beyond that.
