Berkey Ceramic Water Filters


Super Sterasyl Ceramic Filter Elements

SKU: N/A Category:


The Berkey ceramic water filters are designed for use in all systems except for the Go Berkey.

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 Sterasyl Berkey ceramic water filters, when used in in-line housings, is certified by the National Sanitation Foundation (NSF) as meeting their Standard No 42 for materials.
