First stage: The first stage consists of Doulton supercarb ceramic which provides genuine sub-micron filtration. The cartridge reduces fine particulate matter, bacteria, cysts and turbidity.

Second stage: The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilizing properties, preventing the growth of bacteria.

Third stage: An inner core of activated carbon block removes chlorine and organic compounds

Benefits: 
Supercarb™ has all the benefits of Sterasyl™ (removal of particles, pathogenic bacteria, cysts etc.) with additional chlorine & organicsremoval capabilities.
