Ultra Slim

Handmade from stoneware clay and fired to 1305 degrees celsius this purifier has been glazed using non-toxic materials and is the perfect container for storing water. The 12 month/ 2000 litre Royal Doulton Super Sterasyl® which is standard on this system removes virtually all contaminants except fluoride; if fluoride is an issue please order with the SCP Fluoride Plus™ filter, also good for 12 months or 2000 litres, in the order box just below.

The ultra slim water purifiers come with a separate ceramic stand and holds approximately 10 litres. The inverted bell housing the filter at the top of the purifier holds about 3 litres so that at any given time about 7 litres can be accessed from the tap at the bottom. The ultra slim purifier is approximately 220mm wide and 550mm high including the stand.

How does it work?

Water is placed in the the top container, shaped like an inverted bell, which houses the ceramic filter which has a nozzle protruding through a small hole into the main body of the purifier (please refer to illustration). Water is filtered in three ways.

The outer micro-porous ceramic wall screens the water down to one micron to remove up to 99.99% of bacteria and suspended solids. The tiny pores of the cermic make it extremely efficient at removing particulate matter and fine sediment. The ceramic is also a highly effective barrier to bacterial pathogens and water-bourne cysts including e-coli, cryptosporidium, giardia and salmonella.

The water passes through the inner core of activated charcoal which removes chlorine, ammonia, fluoride and bad tastes and odors. Activated carbon works by attracting and holding certain chemicals as water passes through it; it is a highly porous material with an extremely high surface area for contaminant adsorption. (Adsorption is the phenomenon whereby molecules adhere to a surface with which they come in contact with).

The ceramic wall of this filter has been impregnated with silver ions to prevent the growth of bacteria in the filter itself and also in the stored water. The silver acts as a natural biocide inhibiting microbiological growth meaning that there is no need to sterilise the filter even when they are used over an extended period of time.

This design prevents any overflow problems common with two part systems. Each purifier is hand made on the potter's wheel and individually decorated in a variety of colours, many of which are uniquely Australian.

The purifier is fired to stoneware temperature of 1305 centigrade making it the perfect non toxic material to filter and store drinking water. Firing at this high temperature ensures your water purifier is waterproof and extremely resilient to cracking, crazing and chipping.

Unlike terracotta and earthenware systems, our stoneware system will not grow mould, become stained, deteriorate with age or leave a clay taste in your water. The inside of the purifier is glazed allowing ease of cleaning.

No fumes are given off as with plastics or metals allowing safer long storage. The insulating properties of stoneware will help keep your water naturally cool for drinking and ice may be added to the container for chilled water. There is no electricity or plumbing and the purifier is small enough that it can be moved easily from room to room.

Royal Doulton Super Sterasyl Filter

The Sterasyl™ Ceramic Shell

The Sterasyl™ grade ceramic is designed to remove suspended solids and pathogenic bacteria (>99.99%). 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 1,000º C. They are designed to operate with water flow going from the outside to the inside of the element. The ceramic shell exhibits a strictly controlled pore structure, so as to provide efficient sub-micron filtration, a proven defense against hard-shelled parasites such as Cryptosporidium as well as pathogenic bacteria. The ceramic also removes other less harmful, but equally unpleasant particulate debris such as rust and dirt.

Composition of the Sterasyl™ ceramic contains pure silver. This silver is a material designed to significantly inhibit bacteriological mitosis or grow through. The result is that bacterial growth is inhibited from occurring within the Sterasyl™ ceramic element (which is possible with the other ceramic filter elements). This silver content insures that filtered water contains levels well below those required by international standards. Because of the silver, Sterasyl™ filter elements do not require sterilization after cleaning.

The Sterasyl™ filter, when used in in-line housings, is certified by the National Sanitation Foundation (NSF) as meeting their Standard No 42 for materials.

The Super Sterasyl™ Water Filtration Element

The Sterasyl™ ceramic is the ceramic shell used for the Super Sterasyl™ filter element. Accordingly, this filter element will have, at a minimum, the filtration benefits of the Sterasyl™ ceramic. Additionally, the bore of the ceramic shell is filled with granular activated carbon, which enables the filter to reduce chlorine and organic chemicals while improving the color, taste, and odor of the source water. The re-cleanable Super Sterasyl™ filter elements remove suspended solids, parasites, cysts and pathogenic bacteria (>99.99%) and reduce organic chemicals, pesticides, herbicides, organic solvents, trihalomethanes, SOCs, VOCs and foul tastes and odors. The top of the Super Sterasyl™ element is closed with a unique ceramic dome. This prevents the possibility of breeching (leakage), which can occur with filtration elements that are closed with a plastic cap.

What’s Hiding in Your Drinking Water? Super Sterasyl™ Filters:

  • Remove Pathogenic Bacteria: Cholera, Typhoid, Salmonella, Serratia, E.Coli, Fecal Coliform > 99.99% removal.
  • Remove Cysts (>99.999%): Cryptosporidium Parvum and Giardia Lamblia - 100% removal (based on tests by Arizona State University).
  • Reduce Organic Chemicals: Pesticides, herbicides, organic solvents, SOCs, VOCs, trihalomethanes.
  • Reduce Chlorine > 95%
  • Reduce Turbidity, Sediment and Particulate:
    @ 0.9 micron> 99.99%
    @ 0.5 – 0.8 micron> 99.9%

Super Sterasyl™ ceramic filters are manufactured to the following international standards and have been tested and approved by the following independent bodies or agencies:

ISO-9000: 2000, Hyder Labs – UK, Spectrum Labs – UK, WRc – Mednenham UK, Clare Microbiology – UK, Loughborough University - UK, University of Arizona – USA, Thresh, Beale, and Suckling – UK, and WRc Gwent – UK.

Bacterial mitosis and “grow-through” Mitosis is the name for the usual method of bacterial cell division. This division is characterized by resolving the chromatin of the cell nucleus into a threadlike form that condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of the two new daughter cells. When conditions of growth (cell division) are right (proper environmental conditions, temperature, pressure, etc.) and sufficient nutrients, the “threadlike forms” can penetrate ordinary ceramic structure and create bacterial cells on the inside of ceramic elements. The Sterasyl™ grade filter elements incorporate pure silver into the porous ceramic shell, which inhibits mitosis or “grow-through”.

Benefits of Ceramic Water Purifiers

Our bodies are at least 75% water. Adults should drink a minimum of 8 glasses of pure water a day to prevent dehydration. Water is essential for our bodies to function properly as it facilitates nutrient absorption and removal of wastes.

The water from our taps is now heavily polluted with contaminants such as lead from petrol fumes, dirt, hair, rust, slime, hydrocarbons, algae, agricultural pesticides, industrial wastes just to name a few. Add to these the contaminants added by water authorities such as chlorine, aluminium and copper and you have a foul smelling and foul tasting toxic cocktail.

If you are drinking tank water the quality of the water may be worse. Birds, frogs, rodents, reptiles and insects can all get into rainwater tanks and their droppings can pollute the water. Material such as dust, leaves, twigs, cane ash, corroded metal, residues from roofing products, smoke, woodfire particles and remains of agricultural aerial spraying can also find its way into your tank and taint the water.

If your water supply comes from dams, springs, streams or underground bores you have the added concern of faecal contaminants leeching from septic tanks as well. The need for effective purification of drinking water has never been greater.


The Southern Cross Pottery Water Purifying system together with a carbon activated ceramic filter are extremely efficient at removing impurities such as bacteria, chlorine, amoeba, suspended solids, organic pesticides, heavy metals and cysts. Specifically laboratory test results show that the Royal Doulton Super Sterasyl® filter used in our pottery water filter system will remove up to:

  • Bacteria Reduction (E.coli, Cholera, Salmonella) 99.99%
  • Cyst Reduction ( Cryptosporidium & Giardia) 99.99%
  • Algae,Rust,Sediment Reduction 99.99%
  • NSF Turbidity Reduction std.53 99.69%
  • Chlorine Reduction 95%

Our new SCP Fluoride Plus™ filter removes everything mentioned above PLUS 97% of fluoride, 99% of chloramines, 99% of lead and 97% of glyphosate and lots more.
