Technical Features

Drip Filter Purpose and Action Microfiltration of water which may be contaminated by infective organisms. Katadyn filters were originally designed to meet Swiss standards for removal of all bacteria from natural untreated water sources such as rivers, streams, lakes, ponds, springs, reservoirs and wells. They are also used on dechlorinated water to remove bacteria which may pass through or incubate and multiply on the wet charcoal filters used to remove chlorine or chemicals. Giardia and other cysts, as well as, coliform and the smallest known bacteria were shown to be completely removed in many tests. Tests also demonstrated zero bacteria in the filtered water after idle intervals, demonstrating that no bacteria incubate within the filter. Contamination of the ceramic filter element by harmful bacteria is prevented by bacteriostatic silver which is dispersed and fixed throughout the ceramic material by Katadyn's proprietary manufacturing process. This protection lasts up to the end of the life cycle of the element. The Katadyn Drip does not remove 99.9% of viruses and does not remove dissolved minerals or chemicals. Therefore, sea water or brackish water is not desalinated. Nor is water softened by removal of the hardness, minerals, calcium, and magnesium, normally considered beneficial in water for drinking and food preparation. Parasites, algae, pollen, fungi, asbestos fibers, nuclear explosion debris, invisible dust particles, as well as, larger suspended particles and sediment are removed by Katadyn filtration. Therefore, water is clarified and often tastes better. The outside surface of the ceramic filter element may temporarily plug up by the particulate matter in water. The exterior of the ceramic is then wiped or brushed to restore the normal flow rate. The Katadyn Drip when used with the ceramic element (Ceradyn) does not remove chemicals. When used with the ceramic/carbon element (Gravidyn) unpleasant taste, odor, and hazardous chemicals are removed. The Gravidyn dual filtration element for the Drip offers ceramic and activated carbon filtration. (Microporous, silver incorporated CERAMIC with pore size of 0.2 micron. Retains suspended matter, all harmful bacteria and parasites such as cryptosproidium and giardia. Essential minerals remain in the water.The high performance ACTIVATED CARBON inside removes unpleasant taste and odor such as chlorine and hazardous chemicals. Once used the Gravidyn has to be replaced after 6 months.)
