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.

This cleanable ceramic water filter element is designed to reduce suspended solids, pathogenic bacteria, organic chemicals, and improve taste and odor. The 10" Super Sterasyl ceramic element is available only as a "candle" (fitted with a threaded plastic cap on one end).

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; it is not recommended for high pressure (high flow rate) systems. If used in pressure filters, the GAC granules may shift and "channelize" which could allow water to flow through the filter without and contact with the GAC.
