About MICROPUR
MICROPUR focuses on water preservation and chemical disinfection, addressing how water can stand the test of time once it leaves a fixed water supply system.
When water is stored in bottles, tanks, buckets, or backup containers, it's not just the quantity that needs to be managed, but also its condition during storage.
People often interpret "preparing drinking water" as simply filling containers, but once water is stored, time becomes a new factor. MICROPUR, building on the legacy of silver ion water preservation technology, brings water storage management into contexts such as travel, boating, mobile living, and long-term backup scenarios.

Starting with Silver Ion Technology in 1928
In 1928, Alexander Krause in Switzerland developed a technique for preserving drinking water using silver compounds. This technological lineage gradually evolved into the water preservation and disinfection system represented by MICROPUR.
Its value lies not in dramatically changing water, but in helping users address often overlooked problems during water storage, under clear usage conditions.
Once Water Leaves the Supply System, Time Becomes Crucial

Boat water tanks, RV water tanks, remote locations, mobile water storage containers, and long-term backup water all share a common characteristic: once water is filled into a container, it doesn't stop changing just because it looks clean.
MICROPUR extends water treatment from "the moment water is obtained" to "the entire period of water preservation and retrieval," allowing users to establish a more comprehensive management approach based on water volume, container type, and estimated storage time.
Preservation and Disinfection are Two Different Tasks
Applicable to clear water that already meets drinking standards. The focus is on reducing the impact of microbial proliferation during storage.
For clear water from unknown sources, treatment must follow the product's active ingredients, contact time, and usage instructions.
Suspended solids affect treatment effectiveness. Water must first be settled or filtered for subsequent treatment to be more reliable.
Silver ions and general chemical disinfection methods do not treat salinity, heavy metals, or chemical pollution; source water risks must be assessed before use.
When It Succeeds, Nothing Happens

Some equipment demonstrates its work with flames, flow rates, or mechanical operation, but MICROPUR is entirely different. When it works correctly under the right conditions, the water doesn't suddenly change color, nor does it leave any noticeable traces.
The true achievement is that the water in the container remains in a manageable and usable state after a period of time. This is the most valuable, yet often overlooked, aspect of water preservation.
Responsible for the Time Aspect in a Complete Water Treatment System
Today, MICROPUR is one of the specialized brands within the Katadyn Group's water treatment solutions. Physical filtration, UV-C, chemical disinfection, and reverse osmosis each address different problems; MICROPUR's role is always clear: to ensure that stored water and disinfection can be correctly managed according to source water conditions.
It does not replace all water treatment technologies, but rather transforms the most easily forgotten period after water leaves a fixed supply system into a manageable process.
Making Drinking Water Stand the Test of Time
The story of MICROPUR is a lineage of water preservation extending from silver ion technology. From personal water bottles to large water tanks, the container size may differ, but the core problem remains the same: when water starts to wait, how do people continue to manage its condition?
