Since 1928
Title
Katadyn is founded in Switzerland with a
clear purpose: applying science and engineering to one of life's most essential needs - safe drinking water. What begins with water treatment will become the
foundation for almost a century of specialist expertise, innovation and trust.
Inside the first field trial
With the Pocket Filter, dependable water treatment becomes truly portable. Built for demanding use and designed for longevity, the product helps define Katadyn's reputation for field-ready water filtration and becomes one of the most recognisable products in the company's
history.
Our expertise expands beyond water filtration.
Katadyn's expertise grows beyond portable
filtration. The company applies its knowledge to larger water-treatment challenges and develops capabilities in technologies such as ultraviolet disinfection - expanding the environments in which Katadyn solutions can be
used.
Katadyn enters the US market.
As demand for dependable water treatment grows internationally, Katadyn establishes a presence in the United States. It marks an important step in the transformation from a Swiss specialist into an increasingly international brand serving customers and missions around the world.
Beyond water.
The addition of Trek'n Eat broadens the Katadyn mission. Specialist outdoor and expedition meals add nutrition to the Group's expertise, reflecting a wider understanding of self-sufficiency: people operating beyond conventional infrastructure need more than safe water alone.
Adding fire to the mission.
With Swedish stove specialist Optimus,
Katadyn adds another essential capability: cooking. Water, nutrition and the ability to prepare a hot meal now come together within the Group - strengthening Katadyn's role in supporting self-sufficiency outdoors and in
demanding environments.
Expanding specialist nutrition.
Katadyn further expands its food expertise with AlpineAire Foods. The established American specialist in freeze-dried
meals strengthens the Group's nutrition portfolio and adds decades of experience serving outdoor users, emergency preparedness and other demanding applications.
From freshwater to the world`s oceans.
The addition of Spectra Watermakers takes
Katadyn's water expertise from freshwater sources to the sea. Advanced desalination technology strengthens the Group's capabilities for marine, remote and off-grid applications where producing fresh water independently can be essential.
Prepared for emergencies.
Katadyn strengthens its capabilities in emergency preparedness through MSI, adding specialist expertise in long-life food and special nutrition. The expansion supports humanitarian, civil-protection and emergency applications where dependable nutrition must remain available when normal supply systems are disrupted.
Strengthening our global presence.
Katadyn continues to build the international network needed to serve increasingly diverse markets and
missions. A stronger presence in Asia brings the Group closer to customers, partners and applications across one of the world's most dynamic regions.
Built for what comes next.
Nearly a century after Katadyn began with
one essential challenge - making water safe - innovation continues. In 2026, the BeFree AC Bottle brings fast, convenient filtration and activated carbon
into an everyday bottle format, while the Explorer Pro Purifier combines multiple treatment stages in a modular system designed for demanding backcountry use. Together, they demonstrate how Katadyn continues to evolve its water-treatment expertise while the wider Group brings together Filter, Food and Technology for the mission ahead.
