The Sterasyl® ceramic is fitted with an activated carbon block insert which contains lead removal media to produce the Ultracarb®. Among other things, activated carbon is very effective at removing chlorine and organics from water. Ultracarb® is designed to be used in pressure filters (on a mains water supply), not in gravity filters.
Ultracarb® has all the benefits of Sterasyl® (removal of particles, pathogenic bacteria, cysts etc.) with additional chlorine, organics and lead removal capabilities.
A scale inhibitor version, Ultracarb SI® is also available upon request...
