This refill capsule is designed for the Hello Klean Rain Shower and Shower Filter to improve your water quality. It is formulated with KDF 55 to reduce water-soluble metals like lead, iron, copper, mercury, and nickel. Calcium Sulphite helps to reduce chlorine, while Granular Activated Carbon reduces trihalomethane (THMs) and odour. Ceramic Beads are included to boost filtration. Testing shows it reduces over 90% of chlorine, and 88% of users reported softer hair and skin after one month. Each capsule can purify 13,000 litres of water, typically lasting 4-5 months depending on household size.
