REPLACEMENT FILTER FOR GRAYL GEOPRESS 710 ML BLACK

Here is a revised version, parallel to the UltraPress version, to maintain consistency on the site:

Replacement Purifier Cartridge — for GeoPress®

Extend the life of your GeoPress® purifier with this official replacement cartridge. Redesigned in April 2023, it integrates a new core and improved flow channels designed to accommodate the one-way valve, now allowing you to safely use your purifier with electrolytes, drink mixes, and other flavored liquids.

Please note: the GeoPress® one-way valve comes pre-installed in every GeoPress bottle.

Designed to last 350 cycles (65 gal. / 250 L) under normal conditions, the cartridge's lifespan may decrease when the treated water contains high levels of silt, sediment, or tannins.

When to replace your cartridge?

The pressing time gradually increases towards the end of its lifespan. When it reaches 25 to 30 seconds (or after 3 years of use), it's time to replace it. Good news: the cartridge continues to protect effectively against contaminants even when the pressing time increases — your safety is never compromised.
