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.

GSS Series - Stainless steel portable gravity water filters.
Made from high quality surgical grade stainless steel for maximum corrosion resistance. Telescopes for easy transport, it is lightweight, durable and easy to clean. Systems supplied complete, ready to use, including SuperSterasyl self-sterilizing ceramic elements and tap.
GSS Series Stainless steel portable gravity water filters with two Doulton® Imperial SuperSterasyl™ 7 inch filtration elements (candles) can produce over 20 gallons per day (GPD) of safe delicious drinking water.
Each filter chamber holds 2.25 gal.(9 L). GSS2 portable gravity filter specifications>.
Used by many of the world's leading relief organizations
including US Military.
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. 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.
