Sterasyl candles

The Doulton Sterasyl is a highly efficient ceramic micro filter which provides genuine sub micron filtration of drinking water.

Sterasyl is manufactured with the highly consistent and controlled pore structure necessary to remove a wide range of water borne contaminants over the life of the candle.

In addition to fine particulate matter, bacteria, cysts and turbidity are removed to a high level of efficiency.

The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria and gives each candle enhanced bacteriostatic and self sterilizing properties for safe handling and cleaning.
