SuperSterasyl Ceramic Water Filter Replacement for Gravity Fed Portable Systems

This cleanable ceramic water filter element is designed to reduce suspended solids, pathogenic bacteria, organic chemicals, and improve taste and odor. The SuperSterasyl 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.

Higher flow rates can be achieved however, chemical reduction efficiency will suffer.
