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 candle, when used in a Doulton HIP housing, is NSF listed and conforms to the requirements of NSF Standards for aesthetic (number 42) and health (number 53) benefits with respect to cyst, turbidity, particulate reduction, and self-sterilizing effects (model HIP/S) and it is registered with the U.S.E.P.A. (registration number 69096-1). The cartridge is open on both ends and fits in standard 10" filter housings.
| Maximum working pressure |
125 psi (8.6 bars) |
| Maximum working temperature |
100 °F (37.8 °C) |
| Minimum working temperature |
40 °F (4.4 °C) |
| Recommended cleaning frequency |
every 6 months or when flow rate is noticeably lower |
| Recommended change frequency |
every 12 months |
| Contaminant Removal |
The great majority of pathogenic (disease causing) bacteria and cysts are larger than one µ. The pore size of the ceramic filter element is controlled so that it will remove all suspended matter larger than 0.9 µ. |
| 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) |
Some restrictions apply to the sale of ceramic filters in the states of CA, WI, MA & IA. Call for details.
