Katadyn Expedition Ceramic Replacement Element
the heart of the Expedition Filter
When a filter sits unused in base camp for months – and then has to deliver safe water immediately: silver quartz gravel keeps the element under control even during idle periods.
Buy the Katadyn Expedition ceramic replacement element – up to 100'000 litres from one element
The Katadyn Expedition ceramic replacement element is the filtering heart of the Katadyn Expedition Filter – the unit that treats large volumes of water in base camps, at relief organisations and in disaster response. The microporous ceramic with a 0.2 µm pore size and firmly anchored silver retains bacteria, protozoa and suspended solids, and can be brushed clean when flow drops. Up to 100'000 litres are possible per element – the highest filter capacity in the Katadyn ceramic range.
Protection while idle
What happens when the filter stands still for months?
That is the critical question for any emergency and base camp filter. A damp filter element left unused for weeks or months is an ideal breeding ground: pathogens settling on the clean-water side would go straight into supposedly clean water on the next use. Katadyn addresses this on two levels in the Expedition element. First, the silver is firmly anchored in the ceramic structure – so it is not washed out. Second, inside the element there is silver quartz gravel that acts as a disinfectant and controls recontamination particularly during longer periods of disuse. The filter therefore stays ready for service even after a long pause.
100'000 litres – what that means in the field
The figure sounds abstract until you convert it. Using the 15 litres of drinking water per person per day common in humanitarian work, a single element covers roughly 6'600 person-days – a camp of 50 people for around four months. That is exactly what the Expedition Filter is built for: not for a backpack, but for stationary water supply where a filter unit has to deliver reliably over long periods. The volume actually achievable depends heavily on water quality – heavily turbid raw water shortens service life noticeably.
Clean instead of replace – as long as the wall holds
Like all Katadyn ceramic elements, this one is cleanable. When flow drops, the surface is brushed: the filter cake of suspended solids comes away and the pores open up again. Each cleaning removes a wafer-thin layer of ceramic – so the element becomes measurably thinner over its life. It is replaced when wall thickness falls below the minimum, when cracks are visible, or when the element has been exposed to frost.
Fitting with a seal – and why it belongs in the box
The replacement element is supplied together with the matching seal. That is not an accessory bonus but functionally necessary: a hardened or deformed old seal can let raw water past the ceramic onto the clean-water side – the filter would keep flowing but no longer filter safely. Such a bypass is not detectable from outside. Replacing the seal is therefore a mandatory part of replacing the element.

Replace in good time – the spare element belongs with the unit
An Expedition Filter rarely stands somewhere you can quickly pick up a spare. That is exactly why a reserve element belongs to the basic equipment of every unit – particularly at relief organisations, in base camps and in emergency preparedness, where the filter has to work immediately and without procurement time when it matters. The element is cleanable and lasts up to 100'000 litres, but grows thinner with each cleaning and is sensitive to frost and impact. The supplied seal is always renewed along with it.
