British Berkefeld® Gravity Water Filters are intended for use in situations where a reliable supply of safe drinking water in unavailable.
Two models are available in the British Berkefeld® Gravity Filter range.
Both filters are compact, portable and simple to operate. Requiring no external plumbing, each filter takes only minutes to assemble and can provide up to 80 litres or 20 US gallons of safe drinking water each day.
This ease of operation combined with a proven effectiveness at eliminating water-borne diseases such as cholera and typhoid, has lead to the filter being specified for field operations by many of the worlds major aid and emergency relief organisations.

Model: LP
Manufactured in food quality, high density polypropylene, the latest LP model is lightweight, durable, virtually unbreakable and can be fitted with 7" or 10" candles to increase output.

Model : SS
This model is manufactured in high grade, polished Stainless Steel for maximum corrosion resistance, as Stainless Steel is hygienic, durable and easy to clean.

The filter consists of two containers. The upper container is filled with untreated water which then filters down into the lower container, through a number of ceramic elements

These ceramic elements are available in STERASYL and SUPER STERASYL grades.

Sterasyl ceramic elements consist of a fine microporous structure, which forms a complete barrier to all particles larger than 0.9 microns in size (1 Micron = 1,000th of a millimetre). All particles above this size become trapped on the surface and within the ceramic. Fine particles of silver are evenly dispersed within the structure of Streasyl, which prevents the growth of bacteria.

Super Sterasyl ceramic elements contain an additional activated carbon filling, which removes chemical and organic compounds from the water and improves the taste.

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, a number of times before replacement becomes necessary.

A rigorous programme of both inhouse and independent testing of British Berkefeld water filters ensures complete verification of all produce performance claims:-
Absolute filtration efficiency to 0.9 microns
For particles from 0.5 to 0.8 microns filtration efficiency is greater than 99.99%
Reduces turbidity by an efficiency greater than 99.7%
Independently tested to remove the following parasites and pathogenic bacteria
