Water Filters Elements
The Doulton ceramic filter is designed to trap bacteria mainly
on the outer surface of the ceramic element preventing them from
passing through into the drinking water.
Given favorable temperature and pressure conditions, the accumulated
bacteria could proliferate and grow unless prevented by some means.
To prevent this our elements (Super Sterasyl) are manufactured with
a small amount (about 0.07%) of silver in the ceramic shell. Silver
is a recognized bactericide, so when the bacteria comes into contact
with the silver impregnated ceramic, their growth is inhibited.
This self-sterilizing effect is known as the Bacteriostatic Effect.
The silver leach rate from the ceramic is very low and always well
below the national recommended limits.
