Most water utilities use Chlorine as a primary disinfectant because of its effectiveness in killing potentially harmful organisms. Increasingly, in recent years, Chloramine has been introduced as a secondary disinfectant to protect the water as it travels from the treatment plant to the point of use.

Doulton Chlorasyl ceramic drinking water filter cartridges / candles are a continuation of the three stage ceramic cleanable filtration cartridges, designed to remove suspended solids, pathogenic bacteria, chlorine, organic chemicals and hydrogen sulphide in drinking water. In addition they will dramatically improve taste, colour and reduce odours.  This style of ceramic drinking water cartridge is available to fit not only Doulton water filter housings but a host of other manufacturers' drinking water filter housings.  This series is a direct fit for Pristine Water Filters and in the product catalogue a 'D' has been placed in front of the part numbers that fit Dynamic Stainless Steel counter top and under counter drinking water purifiers and an 'F' for Franke drinking water filters.
