Ceramic water filters remove bacteria + protozoan cysts
Ceramic filters - How they work
The Ceramic filter has a fine pore size of less than 1 micron which acts as a physical barrier against pathogenic bacteria and protozoan cysts in your water. The filter also acts as a pre-filter to the Carbon Filter and helps to prolong it's efficiency. The removal of Turbidity leaves your water sparkling clean and clear.

What does a Ceramic filter remove?
The filter can remove more than 99.99% of bacteria such as E.Coli, Shigella, Salmonella Typhi and other Bacteria. It can also remove over 99.99% of Giardia Llamblia, Cryptosporidium and other Protozoan Cysts leaving your drinking water pure and safe to drink.
Why remove Bacteria and Protozoan cysts?
Bacteria and protozoan Cysts can cause severe diarrhoea & sickness which can be extremely unpleasant for those in good health. They can also cause chronic illness for the young, the old and the immuno-compromised.
