Cartridge Installation

REMOVAL
Locate the Cartridge “lock tab” at bottom of Inner Press. Then pull out the “lock tab” and unscrew.

INSERT
Firmly grasp Inner Press, then insert Cartridge into bottom of Inner Press.

ROTATE AND LOCK
Firmly grasp Inner Press, then insert Cartridge into bottom of Inner Press.
CAUTION: Proper installation of Cartridge prevents cross-contamination.

PRECAUTIONS

PRESS WITH FRESHWATER ONLY.
Press with freshwater only (no other liquid). NO salt or brackish water. CROSS- CONTAMINATION.
Do not expose/fill the Inner Press with untreated water, cross contamination may occur. If this does happen, disassemble and wash GeoPress° (not Cartridge) with soapy water and rinse thoroughly. Alternatively, thoroughly dilute potential contaminants by pressing (and agitating) water through the cartridge 5-7 times. SOURCING THE BEST WATER. Always begin with the cleanest (least silty) water available. For instance, streams are generally better than lakes and bogs (which are often have higher levels of sediment and tannins).
CYANOBACTERIA, HIGH LEAD LEVELS, MERCURY, ETC. Cartridges are designed to remove trace levels of chemicals and heavy metals. The GeoPress° was NOT designed to protect against industrial disasters, coal ash spills, very high lead levels, mercury, nuclear disasters or toxic blue-green algae (cyanobacteria), etc. Find another water source in these situations.
CAUTION WITH TANNINS. Tannins are natural organic compounds that leach from decomposing vegetation and trees and can cause Cartridges to clog. In high concentrations, tannins are easily recognizable, as they turn water tea- colored and form blackwater rivers. Do no use GeoPresse in water with high tannins.
NO FREEZING. Cartridges are not significantly degraded after one freeze/thaw cycle. However, don’t use a cartridge after 3 or more freeze/thaw cycles. Protect your GeoPress° in freezing temperatures by keeping it full of water and insulate in a jacket or sleeping bag.
NO HOT (OR BOILING WATER) OR MICROWAVES. Do not expose Cartridge towater hotter than 120F (SOL), it will harm purifier media. Do not put the GeoPress` in the microwave.
DURABILITY AND ACCIDENTAL DROPS. Withstands drop tests (at full capacity) up to 6′. Activate.

CARE AND USE

WASH GEOPRESS° (NOT CARTRIDGE) BY HAND.
The Outer Cup, Inner Press, and Drink Cap can all be washed by hand with warm, soapy water. Do not put any components into a dishwasher. Do not wash Cartridge with soap or any cleaning agents.
LONG-TERM STORAGE. Thoroughly dry wet Cartridge by pressing into an empty (no water) Outer ReFill and dump excess water. Remove One-Way Silicone Valve and allow Cartridge to air-dry thoroughly (depending on humidity it will take 2-4 days to completely dry). Hand wash all other parts including One-Way Silicone Valve with warm, soapy water. Reassemble unit to create air tight seal for storage. Cartridges can last up to three years after opening if cared for properly between uses.
LIFESPAN OF CARTRIDGE. In clear water, a Cartridge will be effective for -350 cycles (65 gal/ 250L). Lifespan is shortened in water containing impurities such as mud, silt or tannins. As “press time” reaches -25 seconds (or three years have elapsed since first use) it’s time to replace the Cartridge. Regardless of flow rate, Cartridges are effective (no waterborne pathogens pass). PRO TIP: allow silt to settle out of silty water before pressing. A flocculation agent (such as Alum Power found in grocery stores) speeds up settling.
SHELF LIFE OF UNUSED CARTRIDGES. An unused (and airtight) Cartridge has a shelf life of 10 years.
ON AN AIRPLANE. As an airplane climbs to cruising altitude, cabin pressure drops, causing air to expand inside a Grayl. Prevent leaking by flying with the One-Way Silicone Valve (included with GeoPress”). as this will prevent leaking. Alternatively, fly with your bottle completely empty (no water to leak) or completely full (no air to expand). Once you’ve reached cruising altitude, use normally.
TESTING STANDARDS. Meets or exceeds the US EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers (April 1987).

CARE AND USE

CARE BETWEEN USES

INSTALLATION AND REMOVAL

INSTALLATION
Using your thumbs firmly press and seat the One-Way Silicone Valve into the cartridge. Insert finger into valve if needed.

SEATING & SECURING
Protect the cartridge media by double-checking that the valve is seated and secured. Check proper installation visually, by ensuring the rim of the silicone is flush with topside, and that the base of the Valve is flush with Cartridge floor.

REMOVAL
Using your fingers, firmly pinch the top of the One-Way Silicone Valve, then firmly grasp and remove the Valve from the Cartridge.
Installation and Removal

ONE-WAY VALVE

One-Way Valve

The pre-installed One-Way Silicone Valve prevents liquid from reversing direction and flowing back into the filter Cartridge. Allowing the use of electrolytes, drink mixes, and other beverages with your Grayl.

FILTER YOUR WATER
With a One-Way Silicone Valve installed, make clean filtered and purified water with your Grayl.
ADD YOUR DRINK MIX
Add electrolytes or a sport drink mix to your filtered water (only if One-Way Silicone Valve is installed). Alternatively, you can add any other potable (i.e. safe to consume) beverage vis a vis the Drink-Thru Cap.

WHAT’S A ONE-WAY VALVE?

A Grayl One-Way Silicone Valve consists of six “duck bill valves” that both prevent water (or other beverages) in your bottle from backflowing through the Cartridge and also allow clean filtered water to pass through the Cartridge into the Inner Press.
