The unique design of the Berkey system combines the age-old process of micro-porous filtration used by nature coupled with modern state-of-the-art technology and the highest quality materials to bring you virtually the finest water filtration system available anywhere.

To use, the upper chamber of the unit is filled with water. Gravity draws this water through the exclusive Super Sterasyl ceramic filters, where it then collects in the lower chamber.The two piece housing is portable and can be used virtually anywhere, anytime.

The Super Sterasyl filters reduce up to 99.99% of particulates, cysts, parasites and pathogenic bacteria including E. Coli, Cryptosporidium, Giardia and Salmonella Typhi. Additionally, these filters will reduce chlorine, rust, sediment and organic chemicals. With filtration rating efficiencies of >98% down to 0.2 microns >99.9% at 0.5 microns >99.99% at 0.9 microns (Spectrum Labs). Takes minutes to assemble and can provide many gallons of good tasting, sparkling, whole-some drinking water each day. Constructed of high grade, polished stainless steel making it hygienic, durable and easy to clean. Berkey® water filters are powerful and economical. The unique ceramic filters are impregnated with pure silver, which inhibits bacteria from colonizing within the ceramic. What's more, the durable ceramic filters can be cleaned many times with a soft brush or Scotch Brite pad.

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 pure silver. This silver is a material designed to significantly inhibit bacteriological 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). This silver content insures that filtered water contains levels well below those required by international standards. Because of the silver, Sterasyl filter elements do not require sterilization after cleaning.

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 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 leaking, 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 elements incorporate pure silver into the porous ceramic shell, which inhibits mitosis or “grow-through”.
