Doulton Super Sterasyl Ceramic Filter Cartridge


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

The Doulton Super Sterasyl ceramic and GAC (Granular Activated Carbon) water filter cartridge is ideal for rain/tank water use or low water pressure area.

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

The Doulton Super Sterasyl is a two stage cartridge combining the highly efficient filtration properties of ceramic with the enhanced water treatment properties of activated carbon. It carries a filtration efficiency of 99.99% at 0.9 micron absolute and 99.9% efficiency at 0.2 micron nominal.

We recommend replacing this cartridge every 12-24 months dependent on water quality and usage. Suits all (standard) 10” housings.

2-Stage filtration process

Stage 1 – Doulton ceramic

This stage reduces fine particulate matter, bacteria, cysts and turbidity. The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilising properties.

Stage 2 – Carbon block 1 micron post filter

An inner core of activated carbon block removes chlorine and organic compounds.

Features & Benefits

  • Highly efficient bacteriological filtration.
  • The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria and gives enhanced bacteriostatic and self sterilizing properties.
  • Granulated form of carbon increases available surface area for effective filtration – providing fresh tasting water without unpleasant taste or odour.
  • NSF standards approved.
