Safe drinking water is often taken for granted, yet in many parts of the world reliable supplies of clean water are at a premium.
In many circumstances a piped supply is not available and surface water from rivers, streams or water holes present the only source of water. In this case the water may appear unclear and have an unpleasant taste, but more importantly is often a source for disease. Even clear and apparently fresh water may be polluted with disease causing pathogens.

Portable Gravity Fed Water Filters with Doulton ceramic filtration elements.

These units are intended for use in situations where a reliable supply of safe drinking water is unavailable. Ideal for outdoor travelers, hikers, expeditions, missionaries, etc. Due to their effectiveness at eliminating water-born diseases such as cholera and typhoid, they are being specified for field operations by many of the worlds major aid and emergency relief organizations.

A recent study by a leading UK University showed that use of Doulton/British Berkefeld drinking water filters in a community in Zimbabwe slashed cases of potentially fatal diarrhea (a common problem in Africa caused by pathogenic bacteria and cysts in the water supply) to virtually zero. Doulton/British Berkefeld filters have been proven to work in the most demanding conditions.

Water filtration efficiency:

0.2 microns silver impregnated ceramic shell of SuperSterasyl™ candle (Sterasyl™) effectively remove pathogenic bacteria such as E.coli, cholera, salmonella, shigella, typhoid etc with greater than 99.99% efficiency, 100% removal of pathogenic cysts such as cryptosporidium parvum, giardia lamblia, guinea worm etc.

Inside the ceramic shell is packed bed of coconut shell granular activated carbon ( GAC) for removal of chlorine, VOC's, industrial solvents, bad taste and odor etc. For microbiologically effectiveness the ceramic shell is self-sterilized (no need for boiling) and can be cleaned up to 60 times before is worn off.

NOTE: It should be clearly understood that during tests performances the concentration of bacteria fed to the filtration element is artificially high in order to simulate a challenging test for the ceramic element. The most aggressive "real life" condition would normally be at least 1000 times less severe.
