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.
