Doulton ceramic water filters have been continually manufactured for over 170 years. The first water filters were manufactured in the early 1800’s at Doulton & Co.’s Lambeth works on the banks of the River Thames, London.

Nowadays, Doulton offers a wide range of drinking filter systems, alongside their accredited various grades of candles and cartridges.

Filtration Process

Doulton Sterasyl is a highly efficient ceramic micro filter which provides genuine sub micron filtration to your drinking water.

In addition to fine particulate matter, bacteria, cysts and turbidity are removed to a high level of efficiency. The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria and gives each cartridge an enhanced self sterilising property.
