These two Katadyn Vario Carbon Replacement 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 the filter is so useful, that time will inevitably come round.

The Carbon Vario 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.

Replacing this carbon filter every 500 gallons is very important to keep your water tasting fresh and safe to drink.
