The Sterasyl™ Ceramic Shell
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.
Composition of the Sterasyl™ ceramic contains
silver. This silver is a material designed to significantly inhibit
mitosis or grow through. The result is that bacterial growth is inhibited from
occurring within the Sterasyl™ ceramic element (which is possible
with the other ceramic filter elements). Because of the silver, Sterasyl™ filter
elements do not require sterilization after cleaning.
The Sterasyl™ filter, when used in in-line housings, is
certified by the National Sanitation Foundation (NSF) as meeting their Standard
No 42 for materials.
The Super Sterasyl™ Water Filtration Element
The Sterasyl™ ceramic is the ceramic shell used for the Super Sterasyl™ filter
element. Accordingly, this filter element will have, at a minimum, the
filtration benefits of the Sterasyl™ ceramic. Additionally, the bore
of the ceramic shell is filled with granular activated carbon, which enables
the filter to reduce chlorine and organic chemicals while improving the color,
taste, and odor of the source water. The re-cleanable Super Sterasyl™ filter
elements remove suspended solids, parasites, cysts and pathogenic bacteria
(>99.99%) and reduce organic chemicals, pesticides, herbicides, organic
solvents, trihalomethanes, SOCs, VOCs and foul tastes and odors. The top of the
Super Sterasyl™ element is closed with a unique ceramic dome. This
prevents the possibility of breeching(leakage), which can occur with filtration
elements that are closed with a plastic cap.

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
silver into the porous ceramic shell, which inhibits mitosis or
