These two Katadyn Replacement Carbon Packs mean you can always have a fully functioning cartridge on the go. Generally, the cartridge will filter around 500 gallons of water before it needs replacement but because people find it so useful, that replacement time will inevitably come round again.

The Carbon Replacement Filter is designed to ultimately remove chemicals and micro organisms to make your drinking water safe, simultaneously creating a more natural taste and a nicer smell.

It is really important to replace this carbon filter every 500 gallons to keep your water tasting fresh and safe to drink.
