Doulton Super Sterasyl Micro Filter 10" is a standard 2" x 10" replacement filter candle with a 3-stage filtration process designed to reduce suspended solids, iron, hydrogen sulfide, trace contaminants, bacteria, cysts, turbidity, chlorine, as well as improving taste. The Doulton W9121750 Gravity Ceramic Candle is designed for use in gravity filter systems for Big Berkey and Doulton: Doulton HIP, Doulton HCP, Doulton HIS gravity water filters.

Super Sterasyl filter element is produced by filling Sterasyl ceramic shell with Granular Activated Carbon(GAC) as core. A ceramic has a small and complex pore structure, making it an ideal filter medium. The pore structure of Doulton's ceramic drinking water filters is accurately controlled to remove fine particulates while the ceramic shell is impregnated with oligodynamic silver, as a disinfectant, which inhibits the growth of bacteria on the filter.

This expertise gives the candles the highly consistent pore structure necessary to remove a wide range of water borne contaminants over the life of the filter. With its Absolute filtration rating (defined as >99.99%) of 0.9 microns, Super Sterasyl is highly effective against particulate contamination, pathogenic bacteria, cysts etc., with additional chlorine and organics removal capabilities.

All Doulton ceramic candles and cartridges are bacteriostatic - that is, self sterilizing for bacteriologically safe cleaning and handling.

Key Features & Benefits:

  • 3 stage filtration in one cartridge.
  • Self sterilizing and cleanable filter element.
  • Highly effective barrier to particles and pathogens at 0.2 microns.
  • Long Life/Long term value due to it's washable features.
