0 0


The Katadyn 20720 'Gravidyn' replacement cartridge is a silver-impregnated ceramic with activated carbon inside. The ceramic filter cartridge of the Gravidyn Ceramic has a micro-porous structure with impregnated silver, trapping particles as small as 0.0002 millimeters and delaying the growth of bacteria. Activated carbon is used in combination with the ceramic for its ability to reduce harmful organic and inorganic substances, like unpleasant tastes & odors, pesticides (lindane, DDT) and trihalomethanes (THMs). These substances adhere to the large surface area of the activated carbon. The system itself does not require electricity or a pump. Three filter cartridges combined in this 'base camp' gravity-fed system last up to 40,000 gallons.

  • 0.2 micron filter for ultra-pure, microbe-free water
  • Gravity filter used in wilderness settings
  • Activated carbon granules and ceramic filtration reduce harmful organic and inorganic substances from drinking water
  • Flow rate of about a gallon per hour
