REMOVAL
Locate the Cartridge “lock tab” at
bottom of Inner Press. Then pull
out the “lock tab”and unscrew the
Cartridge
counter-clockwise (lefty
loosey) until it separates from the
Inner Press.
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.
Proper installation of Cartridge
prevents cross-contamination.
CAUTION:
FRESHWATER ONLY.
Use 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 UltraPress® Titanium (not
Cartridge) with soapy water and rinse thoroughly. Alternatively, thoroughly dilute
potential contaminants by pressing (and agitating) water through the
UltraPress® Cartridge 5-7 times.
CYANOBACTERIA, HIGH LEAD LEVELS, MERCURY, ETC.
Cartridges are designed to remove trace levels of chemicals and heavy metals. The
UltraPress® Titanium 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 prematurely clog. In high concentrations,
tannins are easily recognizable, as they turn water tea-colored and form blackwater
rivers. Do not use UltraPress® Ti 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 UltraPress®
Titanium 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 to water hotter than 120F (50C), it will harm purifier media.
Do not put the UltraPress® Titanium in the microwave.
DURABILITY AND ACCIDENTAL DROPS.
Withstands drop tests (at full capacity) up to 6'.
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).

WASH ULTRAPRESS® COMPONENTS (NOT CARTRIDGE) BY HAND.
The Outer Cup, Inner Press, Drink-Thru Cap and One-Way Silicone Valve should
regularly 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 ~300 cycles (40 gal/ 150L). 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
UltraPress® Ti) 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.
