Quick Overview

Fits the Katadyn 'Ceradyn' Systems

Availability: In stock



The Katadyn 20743 'Ceradyn' replacement cartridge is a silver-impregnated ceramic. The ceramic filter cartridge of the Ceradyn Ceramic has a micro-porous structure with impregnated silver, trapping particles as small as 0.0002 millimeters and delaying the growth of bacteria. These cartridges can be used in two different systems: 1) In a system that does not require electricity or a pump, with three filter cartridges combined in a 'base camp' gravity-fed system OR 2) In a system for at-home applications, with the three cartridges combined in a 'domestic' line-pressure-fed system. In either system, the cartridges can last up to 40,000 gallons.
