Grayl GEOPRESS Replacement Purifier Cartridge

Replacement purifier cartridges for the GEOPRESS are designed to last 350 cycles (65 gal. / 250L). Lifespan will decline when purifying water with high levels of silt, sediment or tannins.

Cartridge press time increases towards the end of the cartridge lifespan; when press time reaches 25-30 seconds, the cartridge should be replaced. Cartridge continues to protect, even as press time increases.

Add a GB2 Millbank Bag to greatly extend the life of your Grayl Geopress Purifier.

    Initially out of stock and they let me know by a message they were back and I could order then. Above and beyond customer service, for sure!!!

    We needed two, they only had one left in stock, however, they let us know when they restocked, we order one and it was sent immediately. Outstanding customer service.
