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.
Gravity filters achieve extraordinary filtration due to the high amount of contact time the water has with the filter media. 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.
All portable water filtration systems are fitted with genuine Doulton® ceramic candles. Wing nut and gasket are included with every ceramic replacement element.

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.
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. For more information

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.
