Doulton Ceramic Filter Elements have been trusted by relief organizations around the globe for over 150 years. These filters were developed in 1850 to remove disease causing bacteria from London's Thames River. The bore of the filter ceramic candle contains granular activated carbon to reduce organic chemicals and improve the color, taste, and odor of drinking water. This filter element is suitable for gravity and low pressure filter systems and is not recommended for high pressure (high flow rate) systems. If used in pressure filters, the granules of activated carbon may shift and "channelize" which could allow water to flow through the filter without any contact with the GAC.
