Product Performance

All Doulton® and British Berkefeld® ceramic filter elements are manufactured under International Standards Organisation (ISO) conditions. They have the highly consistent and controlled pore structure necessary to provide genuine sub micron filtration.

Fairey Industrial Ceramics Limited (FICL) takes its product performance claims very seriously. Where drinking water filters are concerned, it is of vital importance that manufacturers’ claims as to the effectiveness of their products at removing contaminants are fully supported by proven test data.

All FICL’s major claims with regard to the performance of Doulton® and British Berkefeld® filter elements and systems have been verified by independent laboratory testing.
