Katadyn Ceradyn Ceramic Filter Element
0.2 µm, up to 50'000 litres
Flow gone despite brushing? This ceramic element returns the drip filter to full output – 50'000 litres and around 100 cleanings per piece.
Buy the Katadyn Ceradyn ceramic filter element – replacement for the drip filter
The Katadyn Ceradyn ceramic filter element is the replacement candle for Katadyn drip filters and for single and double housings in the Endurance series. Its microporous ceramic with a 0.2 µm pore size retains bacteria, protozoa such as Giardia and Cryptosporidium, algae, suspended solids and rust particles. Silver bound into the material inhibits bacterial growth inside the element itself – important given the long idle periods of a gravity filter. Each element filters up to 50'000 litres or withstands around 100 cleanings. Note: a drip filter needs three elements; this listing is for one piece.
A drip filter runs on three candles
Why you need three elements – and when all three are due
The Katadyn drip filter runs three ceramic candles in parallel. That split increases filter area and thus throughput to up to 4 litres per hour – with a single candle the device would be too slow for groups. Because all three elements see the same volume of water, they wear at roughly the same rate: when one is finished, the other two are usually close behind. In practice it therefore pays to replace all three together – that avoids a second change a few weeks later and keeps output even.
Depth filter rather than membrane – hence the long service life
The filtering effect of Katadyn ceramic sits not on a thin surface but throughout the cross-section of the material. When the outermost layer loads up with suspended solids, you brush it off and expose fresh filter material. Around 100 such cycles are possible per element, until the supplied gauge ring signals that minimum diameter has been reached. Up to 50'000 litres accumulate by then – a multiple of what a disposable cartridge manages, and the reason drip filters have persisted in disaster relief for decades.
Silver against contamination during idle periods
A gravity filter stands still most of the time – damp, at room temperature, in the dark. Those are ideal conditions for bacterial growth inside the filter body itself. Katadyn therefore binds silver firmly into the ceramic: it inhibits bacterial multiplication in the element and prevents the filter from becoming a source of contamination between fillings. Dry storage during longer breaks still matters: unscrew the elements, let them dry, store them dry.
What the element does not do
The 0.2 µm ceramic removes no viruses – they are an order of magnitude smaller – and no dissolved chemicals, heavy metals or salts either. To additionally reduce chlorine, lead or taste compounds, combine the ceramic in a double housing with a Carbodyn activated carbon element, or go straight for Gravidyn elements, which unite ceramic and an activated carbon core in one part.

Ceradyn, Gravidyn or Carbodyn – which element fits?
All three element types fit the same Katadyn housings but solve different tasks. Ceradyn is pure ceramic: maximum service life at up to 50'000 litres and around 100 cleanings, unbeatable cost per litre – the choice when microbiological safety and longevity matter. Gravidyn combines the same ceramic with an activated carbon core and additionally improves taste and chlorine levels, but must be replaced after six months at the latest. Carbodyn is a pure activated carbon element, combined with a ceramic in a double housing.

Who is the Katadyn Ceradyn ceramic filter element for?
The replacement element is for anyone running a Katadyn drip filter or a Katadyn filter housing: mountain and club huts, camps, holiday homes, relief organisations – and households keeping their emergency supplies serviceable.
