High-Capacity Filter for Global Water Purification in Field Conditions

The Grayl GeoPress® Replacement Purifier Cartridge provides powerful, fast, and reliable filtration and purification for international travel, remote deployments, and survival operations. Designed to neutralize threats in suspect water sources—from hotel taps in less developed regions to silty streams in austere environments—it ensures your team stays hydrated and protected across every mission.

Built for the Mission

• Proven Global Protection – Removes 99.99% of viruses, 99.9999% of bacteria, and 99.9% of protozoan cysts including Rotavirus, Hepatitis A, Norovirus, E. coli, Giardia, and Cryptosporidium.

• Advanced Contaminant Removal – Filters sediment and microplastics, and adsorbs heavy metals, PFAS, VOCs, pesticides, herbicides, and unpleasant tastes or odors using ultra-powdered activated carbon.

• Fast Press Time – Produces 24 oz of clean water in just 8 seconds (5L/min flow rate), even in challenging environments.

• One-Way Valve Compatible – Allows safe use with electrolyte drink mixes, critical for rehydration in hot climates or operational deployments.

• Rugged & Reliable – Each cartridge is rated for 350 presses (65 gal / 250L) and continues to function safely as press time increases, with a 10-year shelf life when stored properly.
