Doulton Sterasyl™ 10 Candle

Doulton ceramic filter screws into the Doulton housing with a closed bottom end.

The Ceramic

The Sterasyl grade ceramic was designed to remove suspended solids, turbidity, parasites and pathogenic bacteria, it is cleanable to provide a longer service life than non-ceramic filter elements. The ceramic utilizes the natural micro-porous properties of diatomaceous earth in the ceramic along with careful monitoring of the firing schedule, to provide strictly controlled filtration efficiency together with optimum pore distribution giving maximum flow.


The incorporation of our EPA registered silver in the Sterasyl ceramic prevents the growth of bacteria on the ceramic and eliminates the need for boiling that is necessary with the Standard filter elements. The silver content and the amount of silver leached into the drinking water during use is well below the levels recommended by the World Health Organization and the EPA.

NOTE: The Sterasyl ceramic is the same ceramic as is used for the shell of the following filter elements:
Supercarb, Ultracarb, Super Sterasyl
