KATADYN Switzerland | Since 1928, leading the world in mobile water purification with silver ion technology
Water source does not equal drinking water.
When people leave stable water supplies to venture deep into forests, sail across oceans, travel to remote areas, or face infrastructure breakdowns after a disaster, the truly important question is not just "where is there water," but how to treat the available water into reliable drinking water.
For nearly a century, KATADYN's development has consistently answered this question.

Brand Key: Starting with silver ion drinking water preservation technology in 1928, KATADYN entered the portable water filtration field in 1952. Since then, it has continued to develop personal water filtration, group water supply, and manual desalination equipment, truly bringing water treatment to the water source itself.
1928: Starting with Drinking Water Preservation
In 1928, chemist Alexander Krause applied silver ion technology to drinking water preservation. The core of this treatment was not to find more water, but to inhibit microbial reproduction after water was acquired, keeping drinking water usable during storage.
The name KATADYN combines the concepts of catalysis and trace dynamics. The brand initially addressed the problem of how to maintain drinking water safety when people leave stable water supply systems.
This starting point determined KATADYN's subsequent direction: water treatment must be adaptable to real environments, rather than existing only in fixed equipment and ideal conditions.

1952: Making Mobile Water Purification Possible
In 1952, KATADYN further launched portable drinking water filters, shifting the brand from drinking water preservation to mobile purification.
This shift meant water treatment no longer relied entirely on fixed equipment. From hand-pump filters, cleanable ceramic filter elements, to later lighter filter bottles and gravity-fed filtration systems, KATADYN transformed various technologies into tools that users could carry and operate.
Product forms continuously evolved, but the core remained consistent: even at the water source, people could establish their own drinking water supply according to the environment and their needs.
Different Solutions for Different Water Sources
The stream water by a mountain path, long-stored emergency water, daily supply for remote villages, and seawater around a life raft all present entirely different problems.
Therefore, KATADYN did not just develop a single type of filtration equipment, but established a comprehensive product line covering personal filtration, ceramic microfiltration, gravity-fed group supply, and manual desalination equipment.
Lightweight systems handle immediate water replenishment during journeys; cleanable, maintainable classic equipment addresses long-term use; and manual desalinators allow for drinking water to be obtained at sea or during emergency missions without electricity. This design logic, starting from water conditions, number of users, and mission requirements, is KATADYN's long-established expertise.

The World's Smallest Manual Desalinator, Adopted by the German Air Force Rescue Equipment
KATADYN's factory case records show that the Survivor 06 Titan, customized for the German Air Force, is the world's smallest manual desalinator. It uses manual reverse osmosis technology, designed specifically for pilots in open-sea survival situations after ditching.
This equipment is deployed in life rafts of some German Air Force transport aircraft, early warning aircraft, and helicopters, and also serves as backup drinking water treatment for Army special forces. The Survivor 06 Titan can produce approximately 0.89 liters of fresh water per hour, with a desalination rate of 98.4%, and has NATO Stock Number 4620-01-448-6409.
Its value lies not in maximum output, but in enabling users to convert seawater into drinking water by hand when at sea, without electricity, and without external resupply. This is KATADYN's answer to extreme mission environments.
From Personal Water Collection to Humanitarian Water Supply Sites
KATADYN's technology is also brought to places where safe drinking water needs to be established long-term.
In Wasa and Lumuli, Tanzania, World Vision Switzerland's safe drinking water program distributed 1,626 KATADYN Rapidyn filtration systems, serving 11 villages, schools, health posts, and 1,500 households. In addition to equipment distribution, local training on operation and maintenance was also completed, making safe drinking water a part of daily life.
A factory case in a remote Thai village recorded 120 households receiving KATADYN Drip Filters. These situations illustrate that when stable water supply is insufficient, equipment that can be used long-term, is easy to maintain, and adaptable to local conditions is truly effective in establishing water treatment.

Why the Brand is Trustworthy
From silver ion drinking water preservation technology in 1928 to portable filtration and desalination systems, the brand has consistently focused on drinking water safety.
Personal filtration, ceramic microfiltration, gravity-fed supply, and manual reverse osmosis each correspond to different water qualities, missions, and usage scales.
The Survivor 06 Titan entered German Air Force rescue equipment, bringing mobile drinking water treatment into true no-compromise open-sea survival situations.
From cases in Tanzania to Thailand, KATADYN not only provides equipment but also leaves operational and maintenance capabilities in communities that need safe drinking water.
A Brand That Always Brings Water Treatment to the Field
Today, KATADYN is a leading brand in the global mobile water purification field. It is remembered not just for one classic filter, but for its consistent focus since 1928 on one thing: enabling people to re-establish reliable drinking water sources when supplies are unstable, far from infrastructure, or facing extreme missions.
Technologies and products continue to change, but the question KATADYN answers has never changed: how to transform the available water into reliable drinking water.
