Katadyn is a Swiss brand founded in 1928 and recognized as the global leader in portable water treatment systems. Created by Professor Georg Alexander Krause, the company has spent nearly a century delivering reliable filters, disinfectants, and desalinators that have saved lives during humanitarian disasters, military missions, and expeditions to the most remote corners of the globe. Under its guiding motto "Making water drinking water," Katadyn combines Swiss engineering precision with a global mission: providing safe drinking water to anyone, anywhere. Today the brand is part of the Katadyn Group — a corporation that also manages Trek'n Eat, AlpineAire Foods, Optimus, and Spectra Watermakers.
History and a Breakthrough Invention
The origins of Katadyn trace back to 1929, when Georg Krause developed the Katadyn Pocket Filter — a ceramic depth filter that remains the brand's flagship product to this day. Built from silver-impregnated ceramic and capable of purifying up to 50,000 liters of water, it was the world's first portable device of its kind and carries a manufacturer's 20-year warranty. Over the following decades, Katadyn advanced filtration technology by introducing hollow fiber membranes, gravity filters, Micropur tablets based on silver ions and chlorine dioxide, and compact desalinators for sailors and sea kayakers. In 2012, the brand joined a broader outdoor and survival products group while retaining full technological independence and manufacturing in Switzerland.
Technologies and Product Lines
Katadyn offers four main categories of water treatment solutions. Mechanical filters using ceramic or hollow fiber elements remove bacteria and protozoa without chemicals — all it takes is pumping, gravity, or squeezing a filter bottle. Purifiers (full-spectrum water purifiers) additionally eliminate viruses, which is essential in regions with low sanitation standards. Tablets and chemical products (Micropur) allow water treatment with no equipment whatsoever — simply add a tablet and wait 30–120 minutes. Desalinators enable the production of drinking water from seawater and brackish water. Flagship models include: Pocket Filter (ceramic, up to 50,000 L), BeFree (ultralight hollow fiber filter for squeeze or gravity use), Hiker Pro (field pump filter), Survivor 06 (manual desalinator for sailors), and BeFree Gravity (gravity system for groups). The lineup is rounded out by Micropur MP1 tablets, used by militaries, humanitarian organizations, and travelers worldwide.
Institutional and Military Users
Katadyn products are officially used or recommended by the armed forces of numerous countries, humanitarian organizations (Red Cross, UNICEF, Médecins Sans Frontières), and emergency services operating in natural disaster zones. The Katadyn Pocket Filter is standard-issue equipment for special forces units in several NATO armies. In Poland, the brand is trusted by the hiking and survival communities as well as professionals preparing for crisis situations. Swiss manufacturing quality, long-term warranties, and the ability to replace filter elements translate into products built to serve for decades.
