British Berkefeld® Filter Elements 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).

British Berkefeld® Filter Elements are powerful and economical. The unique ceramic filters are impregnated with silver, inhibiting mitosis.

What's more, the durable ceramic filters can be cleaned over and over, as needed, with a soft brush or ScotchBrite® pad.

British Berkefeld® Water Filters Elements
Ceramic Water Filter Element

The Sterasyl™ grade ceramic is designed to remove suspended solids and pathogenic bacteria.

Composition of the Sterasyl™ ceramic contains pure silver. This silver is a specially formulated self-sterilizing (bacteriostatic) agent. The result is that bacterial growth is prevented from occurring within the Sterasyl™ ceramic element. More importantly, bacterial 'grow-through' is inhibited. Because of the silver, Sterasyl™ filter elements do not require sterilization after cleaning.

The Sterasyl™ ceramic is the ceramic used for the Super Sterasyl™ filter element. Accordingly, this filter element will have, at a minimum, the filtration benefits of Sterasyl™.

Toxicological extraction is commonly the most difficult area of the NSF testing standards to satisfy. This shows that the filter does not re-contaminate the water. Many other ceramics have not passed and may not be capable of passing the NSF material extraction test. The Ceramic shell of our Super Sterasyl˙ element is an NSF Listed Component and is manufactured to meet NSF standard 42 for materials.

Super Sterasyl Candle Water Filter Element
This cleanable filter element is designed to reduce suspended solids, pathogenic bacteria, organic chemicals, and improve taste and odor. 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 1000C. They are designed to operate with water flow going from the outside to 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 removing other less harmful, but equally unpleasant particulate debris, such as rust and dirt. The bore of the filter candle contains granular activated carbon that aids in the reduction of chlorine, reduces organic chemicals and improves the color, taste, and odor of the source water. The Sterasyl™ element has a unique domed ceiling assuring that leakage cannot occur as may happen with capped filters.

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 the ceramic structure of other ceramic shells and create bacterial cells on the inside of the element.

Sterasyl™ grade filter elements incorporate silver into the porous ceramic shell to inhibit the occurrenceof 'grow-through'.
