There are many variations of the A ceramic pot filter: some are made entirely from ceramics such as the Potters for Peace filters, some have consists of a ceramic flowerpot-shaped pot hanging in a plastic container such as Filter Pure (Agua Pure), while others use plastic buckets and made from a porous ceramic candle (Ketadyne)material. Frequently, Water poured into a colloidal silver coating is added to the ceramic pot filterpercolates through the pot material, and is collected in a second container.

Ceramic pot filters usually have a diameter of about 30 cm by 25 cm deep, with an 8 litre capacity. Two There are many variations of the ceramic filter: some are made entirely from ceramics such as the Potters for Peace filters, flat-bottom and round-bottom, are currently manufactured.  The some have a ceramic pot typically sits or hangs hanging in the top of a larger plastic or ceramic container such as Filter Pure (20-30 litresAgua Pure), which is fitted with a tap at the bottom. A lid is placed on top of the filter to prevent contamination.  Ceramic pots are usually made from local clay mixed with a combustible material like sawdust, rice husks or coffee husks. The clay and combustible material are sieved through a fine mesh, and then mixed together with water until it forms a homogeneous mixture. The mixture is pressed into shape using a mold. When the pot is fired in a kiln, the combustible material burns outFrequently, leaving a network of fine pores through which the water can flow through.  Colloidal colloidal silver coating is sometimes applied added to the ceramic pot after firing or added to the clay mixture prior to firing. Colloidal silver is an antibacterial which: - Disables the enzyme that pathogenic bacteria and fungi use for oxygen metabolism, thus suffocating them. <br>- Destroys pathogens with an electric charge, causing their internal protoplast to collapse. <br>- Renders pathogens unable to reproduce. <br>- Kills parasites while in their egg stagefilter. Some ceramic pot filters also include activated charcoal in the clay mixture to improve odour, taste, and colour.  Pathogens and suspended material are removed from water through a combination of biological and physical processes.  Quality control on the size of the combustible materials used in the clay mix ensures that the filter pore size is small enough to prevent contaminants from passing through the filter. Colloidal silver aids treatment by breaking down pathogens’ cell membranes, causing them to die.
