Pump filters

Even clear surface water can be a breeding ground for many pathogens. Bacteria and protozoa are micro-organisms that can spoil your trip. Each of our mechanical pump water filters is adapted to your different needs, whether you're going on vacation, hiking or camping. Katadyn and MSR pump-operated water filters are suitable for use on their own, for wilderness activities, or with several people in a base camp, for example. They function simply like a sieve system, so that overly large micro-organisms (protozoa 1 to 15 microns, bacteria 0.2 to 5 microns) cannot pass through the micropores or meshes(0.2 microns). Mechanically treated filters are made up of either :

• -
• Ceramic filter, with a long service life, it can filter very turbid water, wear is measurable, also composed of silver which stops the development of bacteria in the filter, but the flow rate is lower -
• Fiberglass filter, light and economical filters with a high flow rate, but the service life is lower, the cartridge must be replaced when the filter is clogged.

Some of these expedition and trek water filters are also equipped with activated carbon. This component reduces pesticides and other chemical pollutants to improve the smell and taste of the water. To eliminate viruses, too small to be filtered (0.02 to 0.2 microns), present in water in populated areas, accompany your pump water filter with a chemical treatment such as Micropur Forte.
