PLEASE NOTE: Katadyn items CANNOT be shipped outside of the USA.
Ceramic filters have a micro porous structure with impregnated silver which delays the growth of bacteria. The pore-size of Katadyn ceramic filters is 0.2 micron (0.0002 mm). Bacteria range in size from 0.2 to 5 micron and, like protozoa (1 to 15 micron), are efficiently filtered out. Ceramic filters can be mechanically regenerated and the filter capacity is measurable.
Activated carbon is used for its ability to reduce harmful organic and inorganic substances in the water. It removes unpleasant tastes, odors, chlorine, pesticides (lindane, DDT) and trihalomethanes (THMs). These substances adhere to the large surface area of the activated carbon. Activated carbon granulate cannot be regenerated.
