All Doulton ceramic candles are bacteriostatic - that is, self sterilizing for bacteriologically safe cleaning and handling.
Choice of Sterasyl or Supersterasyl
candles. Sterasyl candle is designed for microbiological protection
whilst Supersterasyl is a Sterasyl shell packed with with selective
activated carbon for chlorine, bad taste and odor, pesticides, herbicides
and industrial solvents reduction. Due to the carbon exhaustion
change Supersterasyl candles every six months.
When not in use air dry the ceramic candle(s) for minimum of 24 hours
then store in dry place.
These candles provides: 100% rejection of cysts and >99.99% of pathogenic
bacteria such as cholera, typhus, amoebic dysentery, ecoli,
colibacillose or bilharzia, anthrax spores among others. Depth filtration of particulates >0.2 µm (dirt, asbestos, iron
etc). Test Results>>

Doulton ceramic drinking water filter elements utilize the natural properties of high purity
specialized diatomaceous earths to provide a range of strictly controlled
pore sizes giving maximum filtration efficiency together with high
porosity for maximum flow. Doulton ceramic filter elements can
be quickly and easily cleaned many times to prolong their working life.
The filter elements are produced using the latest ceramic techniques
to provide a hollow porous ceramic which is fired at a temperature
in excess of 1000 C. They are designed to operate with water flow
going from the outside to the inside of the ceramic element. A variety of
dedicated fillings can be placed inside the bore of the element
to combat specific water contamination problems. For more details
see Doulton drinking water filtration technology.
All the regular elements are produced in two inch (49 mm) nominal
diameter. Standard lengths are five inch (13 cm), seven inch (I
8 cm), and ten inch (25 cm). For mounting purposes all candle elements
are traditionally supplied with a food grade plastic mount which
terminates in a 1/4inch BSP male thread. There are two standard
length mounts; the long (L) mount is 1-5/8 inch (41 mm) long used in
gravity filters, the short (S) mount is 3/4inch (19 mm) long used in
pressure systems as well on most gravity filters.
