OVERVIEW

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. Compatible with One-Way Silicone Valve for electrolytes and drink-mixes.

New Grayl Filter and One way valve
I love my Grayl Geopress. The only draw back was having to carry another water bottle if I wanted to mix an electrolyte drink because of the risk of damage to the filter. Now with the new filter and one way valve I can lighten my load and use my Geopress
