The robust Katadyn Pocket is a ceramic depth filter against bacteria, protozoa, and other pathogens. The pores of the filter ceramic (pore size: 0.2 micron = 0.0002 mm) are smaller than the microorganisms. Due to their size, these cannot pass through the filter element and are removed from the water.
Unlike disposable filters, the Katadyn ceramic, which has been proven a hundred times over, can be cleaned several times - regeneration is also possible without any problems when on the move.
With 1 liter/minute, the time saving is also a significant plus point with the silver-impregnated ceramic filter. The lifetime is up to 50'000L, depending on the water quality.
