The tried and tested Katadyn Pocket ceramic water filter removes bacteria, protozoa and other disease-causing agents. The microorganisms cannot pass through the pores of the filter ceramic (0.2 microns) because of their size (greater than 0.2 microns = 0.0002 mm). 

Unlike disposable filters, the ceramic can be cleaned several times - even in the field. 

Quickness counts too with an output of 1 litre/minute through a silver-impregnated ceramic filter. The capacity is up to 50'000 litres, depending on the water quality. 

Made from top-quality, durable materials and with a 20-year warranty.

The Pocket is suitable for the toughest of conditions and is the first choice for extreme adventurers. Decades of military and emergency professionals around the world have put their trust in the Pocket's ability to deliver water free of bacteria and protozoa.
