Imperial SuperSterasyl filters are 9" tall by 2.75" in diameter, thus having more surface area and carbon inside each filter compared to the standard slimline ceramic filters. The added surface area means that they will last longer and filter quicker than the standard filters. These are excellent for use in gravity filter systems.
The British Berkefeld ceramic filter has a Sterasyl ceramic shell that is impregnated with silver and will remove/reduce pathogenic organisims. The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria giving the ceramics self-sterilizing properties. Underneath the ceramic shell is granular activated carbon which removes/reduces chlorine, bad tastes and odors. The British Berkefeld ceramic filters do not remove the beneficial minerals from the water.
