This filter system is great for
everyday use but is especially designed to micro-filter a supply of
safe drinking water from cisterns, ponds, streams, and other sources
of questionable water. These 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 30 gallons of safe drinking water each day. The high-tech silver-impregnated
ceramic elements feature a nominal filtration efficiency of 0.2 microns and an absolute rating of 0.5 microns 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 filter elements remove rust and cloudiness, and the activated carbon
core removes undesirable tastes and odors. They are great for camping.
The ease of operation combined with
a proven effectiveness at eliminating water-borne diseases such as cholera
and typhoid has led to the filter being specified for field operations
by many of the world's major aid and emergency relief organizations.
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 = 1,000th
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. The British Berkefeld
elements also contain an additional activated carbon filling,
which removes chemical and organic compounds from the water and
improves its taste. The proprietary system produces not only
safe water but great tasting water!
