This filter’s enhanced catalytic functionality has 4 times the capacity for reducing chloramines than standard carbon blocks and 2 times the capacity for reducing chlorine over standard activated carbon.

Chloramine, an alternative to chlorine, is widely used as a residual disinfectant to maintain water safety. Chloramine is formed by mixing chlorine with ammonia, creating a more stable and less reactive compound than chlorine alone. While this stability reduces the formation of Disinfection By Products (DBPs) and provides longer-lasting disinfection, chloramine is dif­ficult to remove using conventional ­ filtration technology. In addition, because chloramine is a more stable chemical, systems designed for reducing chlorine are not effective with chloramine. Effective reduction of chloramine requires catalytic carbons, or surface-modi­fied carbons with active catalytic sites of nitrogen groups attached to the vast surface of the activated carbon.
