Katadyn Exstream® personal water purification systems eliminate the need to carry or locate
safe water, whether you are hiking, traveling or in an emergency situation. Only Katadyn
Exstream personal water bottle purifiers place the advanced technology of an EPA-registered
microbial purification cartridge into a standard water bottle. The result is a personal
hydration system that provides anti-microbial protection against cysts, bacteria and viruses.
When To Use
Katadyn Exstream personal water bottle purifiers are designed for use with untreated fresh
water sources, such as lakes, rivers and streams. They also provide protection against
waterborne pathogens that may still be present in the tap water of many foreign countries.
Exstream systems are also effective in emergencies, such as floods, hurricanes, earthquakes
or any time service from a municipal water treatment plant fails.
Katadyn Exstream personal water bottle purifiers provide a convenient alternative to pump-
style water purifiers. Because they are designed for personal use, Exstream systems are not
suitable for situations when large volumes of water must be treated.
How They Work
Katadyn Exstream personal water purification systems utilize a multi-stage, modular system.
At the heart of the system is the ViruStat® microbial water purification cartridge. The
ViruStat® uses PentaPure® penta-iodide resin to kill over 99.9999% of waterborne
bacteria, such as Klebsiella terrigena, and 99.99% of viruses, such as Poliovirus type 1 and
Rotavirus Strain SA-11. The ViruStat employs a patented ion-release technology that
dramatically reduces residual iodine, and a special layer of coconut-carbon that further
minimizes any residue. The ViruStat cartridge is preceded by a replaceable 1-micron filter
that removes more than 99.9% of pathogenic cysts, such as Giardia. A Prefilter is installed
below the cyst filter to remove sediment and organic contaminants.
Please read the following instructions carefully for maximum performance from your Katadyn
Exstream personal water purification system. Failure to follow the instructions found in this
guide may result in unsafe drinking water.

Important Notes
1. In order to be purified, water must pass through the ViruStat® cartridge. The flow rate
is slower than an ordinary sports water bottle in order to ensure complete purification.
2. New and stored units must be preconditioned. See section on Preconditioning the
System.
3. Squeeze and sip using continuous pressure. Do not pump. You will notice a 2-4 sec
ond pause after squeezing, like using a long straw, before water flows.
4. Always hold bottle upright when drinking. Water will not pass through the cartridge if
bottle is upside down or at an angle.
Product Set-Up
1.
Rinse inside of bottle
2.
Flush Prefilter
Attach Carbon Prefilter to Bottle Cap. Fill bottle with tap water. Install Bottle Cap on bottle
and tighten. Squeeze bottle firmly with both hands until 1/2 bottle of water has been run
through the system. Remove Bottle Cap.
3.
Assemble the cartridge
Remove the red label from the top of the Virustat (Figure 2). Attach
the Cyst Filter to the bottom of the ViruStat and the Prefilter to the
bottom of the Cyst Filter. Gently twist each component while pushing
it on. Make sure ALL O-rings and components are fully seated and
assembled. The cartridge must be assembled in this way to ensure
purification in all water conditions. Firmly twist and push the car-
tridge into the bottle cap (Figure 3).
1. Prime - Fill the bottle with water to the fill line (indicated on outside of bottle). Insert car-
tridge/bottle cap into bottle. Turn bottle cap clockwise until tight. Squeeze bottle firmly with
both hands to start water flow. Repeat until two bottles of water have been run through the
system. While priming, keep bottle as full as possible. Flow rate will improve once the sys-
tem is fully primed.
2. Again, fill the bottle with water to the fill line. Insert cartridge/bottle cap into bottle. Turn
bottle cap clockwise until tight. Allow to sit for two hours prior to use.
1. Fill the bottle with water to the fill line (Figure 4). Remember, the clearer the water, the
longer the Cyst and Prefilter will last.
2. Insert cartridge/bottle cap into bottle.
Turn bottle cap clockwise until tight.
3. Open bite valve. Note: The bite valve has two
positions. Pull the bite valve out to open. Push
it in to close (Figure 5). Do not remove bite valve.
4. Hold the bottle upright when drinking. Squeeze and
sip using continuous pressure.
