Super Sterasyl™ Ceramic Filter Elements


This product is currently out of stock and unavailable.


Note: We typically recommend using Black Berkey filters before the ceramic options so we no longer carry the ceramic models unless by specific request. Please email us if you have questions on the right filter for your model or a Berkey model you’re looking at purchasing.

The Sterasyl™ grade ceramic is designed to remove suspended solids and pathogenic bacteria (>99.99%). The filter elements are produced using the latest ceramic techniques to provide a hollow porous ceramic, which is fired at a temperature in excess of 1,000º C. They are designed to operate with water flow going from the outside to the inside of the element. The ceramic shell exhibits a strictly controlled pore structure, so as to provide efficient sub-micron filtration, a proven defense against hard-shelled parasites such as Cryptosporidium as well as pathogenic bacteria. The ceramic also removes other less harmful, but equally unpleasant particulate debris such as rust and dirt.

Bacterial mitosis and “grow-through”

Mitosis is the name for the usual method of bacterial cell division. This division is characterized by resolving the chromatin of the cell nucleus into a threadlike form that condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of the two new daughter cells. When conditions of growth (cell division) are right (proper environmental conditions, temperature, pressure, etc.) and sufficient nutrients, the “threadlike forms” can penetrate ordinary ceramic structure and create bacterial cells on the inside of ceramic elements. The Sterasyl™ grade filter elements incorporate pure silver into the porous ceramic shell, which inhibits mitosis or “grow-through”.
