Not all water sources are created equal, but fortunately neither are all filters. The Katadyn Explorer Pro is the first pump filter to combine ceramic microfiltration, activated carbon, and a hollow-fibre virus membrane in a single modular system – meaning you can configure it for the conditions at hand rather than being locked into a one-size-fits-all setup. Heading out on a Scottish bothy trip? Ceramic and carbon will see you right. Travelling somewhere where the water risk is higher? Slot the virus stage in and carry on. All three stages store dry between trips, so there's no mould, no faff, and no excuses for leaving it at home. A steel pump piston and Swiss-made quality control mean this is built to handle heavy use across years of expeditions. Output sits at 1 litre per minute, with ceramic capacity rated to 20,000 litres. At 630g it's not ultralight kit, but when the water source is genuinely sketchy, that's a trade-off most people are happy to make.

Katadyn portable water filters are the filtration equivalent of the iconic Swiss Army Knife: Multi-purpose functionality and time-tested reliability to ensure that no matter where you are or what you’re doing, you can guarantee clean and safe drinking water.
That makes Katadyn filters perfect for personal or group use when hiking, camping, backpacking and travelling – whether you’re drawing water from a river while walking in the hills or setting up a base camp for a trekking party in one of the world’s highest places.
Katadyn filters are built to the highest standards when it comes to quality, reliability and ease of operation. That reputation is why so many military forces and international aid organisations rely on Katadyn products for field use in the most volatile and challenging conflict and disaster zones.
