The GeoPress Grayl replacement filter cartridge restores your bottle to full performance and is compatible with the new one-way valve for electrolytes and beverage mixes.

It removes pathogens, reduces particles, chemicals, and odors, giving you clear, better-tasting water. With a lifespan of 350 cycles (250 liters), it remains effective even under demanding conditions. If the pressing time increases to approximately 25 seconds, replacement is recommended – however, the protective function remains intact.
