About British Berkefeld - Big Berkey PURCHASE British Berkefeld water filters are also compact, portable, and simple to operate. Requiring no external plumbing, each filter takes only minutes to assemble and can provide up to 24 gallons or more of safe drinking water each day. The high-tech silver-impregnated ceramic elements feature a nominal filtration efficiency of : 0.2 microns >98%, at 0.5 microns >99.9%, and at 0.9 microns > 99.99% which effectively blocks waterborne pathogens and clarifies the water. The British Berkefeld uses 4 replacement elements included with purchase of water filter. Introduction Safe drinking water is often taken for granted, and provision is seldom made for a safe backup supply. During emergency situations, a piped water supply may not be available, and surface water from rivers, streams, or ponds may present the only sources of water. In this case, the water may appear unclear and have an unpleasant taste, but more importantly it could be a source of disease. Even clear and apparently fresh water may be polluted with disease-causing pathogens... This filter system is especially designed to micro-filter a supply of safe drinking water from cisterns, ponds, streams, and other sources of questionable water. These very reliable filters are manufactured of high grade, polished stainless steel for maximum corrosion resistance, and are hygienic, durable, and easy to clean. |

British Berkefeld water filters are also compact, portable, and simple to operate. Requiring no external plumbing, each filter takes only minutes to assemble and can provide up to 24 gallons or more of safe drinking water each day. The high-tech silver-impregnated ceramic elements feature a nominal filtration efficiency of : 0.2 microns >98%, at 0.5 microns >99.9%, and at 0.9 microns > 99.99% which effectively blocks waterborne pathogens and clarifies the water. These filters are in common everyday use in households across the country, and are particularly effective on private well systems. The replacement filter elements have an activated carbon core and are designed to remove undesirable tastes, odors, and many organic chemicals. The ease of operation combined with a proven effectiveness at eliminating water-borne diseases such as cholera and typhoid has led to the British Berkefeld Filter being the preferred unit for field operations by many of the world's major aid and emergency relief organizations.
What the filter will remove Absolute filtration efficiency to 0.5 microns (U.S.) For particles 0.2 microns, efficiency is greater than 98%;from 0.3 to 0.5 microns, filtration efficiency is greater than 99% Independently tested to remove the following parasites and pathogenic bacteria:
*(University of Arizona-Sterling) How the filter works The special ceramic elements are manufactured specifically for use in this gravity filter. British Berkefeld ceramic elements consist of a fine microporous structure, which forms a complete barrier to all particles larger than 0.5 microns in size (1 Micron= 1/1,000th of a millimeter). All particles above this size become trapped on the surface and within the ceramic material. Fine particles of silver are evenly dispersed within the structure of the filter element, which prevents the growth of bacteria (mitosis) within the ceramic wall. The British Berkefeld elements also contain an additional activated carbon filling, which removes chemical and organic compounds from the water and improves its taste and odor. After passing through the filter elements, safe, filtered water then collects in the lower chamber to be drawn off from a tap. The structure of the ceramic material is designed to be cleanable, and regular cleaning of the element will allow its filtration efficiency to become regenerated. The elements may be cleaned over 100 times before replacement becomes necessary.
