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.

These cleanable filter elements are designed to remove suspended solids and pathogenic bacteria. The ceramic shell composition and manufacture have been delicately balanced to control flow rate, the maximum pore size and element hardness.

The ceramic contains a specially formulated self-sterilizing silver compound and, therefore, the Sterasyl element does not require sterilization after cleaning. The silver content is precisely controlled to keep well within the maximum levels recommended by the World Health Organization and the E.P.A. The cartridge conforms to NSF Standard (number 53) health benefits with respect to cyst, turbidity, particulate reduction, and self-sterilizing effects.

The cartridge is open on both ends and fit in standard 10″ filter housings.

Larger, Imperial Sterasyl Cartridges are available. These larger elements fit in the same standard filter housing as the Sterasyl shown on this page.

Pathogenic Bacteria Chorela, Typhoid, Salmonella, Serratia, E. Coli, Fecal Coliform: >99.99% removal
Cysts Cryptosporidium parvum and Giardia lamblia: 100% removal (based on tests by Arizona State University)
Sediment Down to 0.9 µ, 100%; 0.5-0.8 µ with a filter efficiency of >99.99% (based on tests by Spectrum Laboratories, Minneapolis, MN)
