1. Prime - Fill the bottle with water to the fill line (indicated on outside of bottle). Insert
cartridge/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 system 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.

Important Notes
1. To be purified, water must pass through the ViruStat® cartridge. The flow rate is
slower than an ordinary sports water bottle to ensure complete purification.
2. New and stored units must be preconditioned. See “Preconditioning the System” section.
3. Squeeze and sip using continuous pressure. Do not pump. You will notice a 2-4 second
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
(Before First Use)
1. Rinse inside of bottle
2. IMPORTANT! Flush Prefilter
Attach Carbon Prefilter to bottle cap. Fill bottle with tap water. Install bottle cap on bottle
and tighten. Firmly squeeze bottle 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 cartridge
into the bottle cap (Figure 3).

Directions For Use
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Katadyn Exstream personal water purification systems eliminate the need to carry or locate safe
drinking water, whether you are hiking, traveling or in an emergency situation. Only Katadyn
Exstream personal water bottle purifiers place the advanced technology of a microbial purification
cartridge into a standard water bottle. The result is a personal hydration system that provides
antimicrobial 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 and 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 purification cartridge. The ViruStat® uses
iodide resin to kill 99.9999% of waterborne bacteria, including Klebsiella terrigena, and 99.99%
of viruses, such as Poliovirus type 1 and Rotavirus Strain SA-11. The ViruStat® employs a patent-
ed 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 99.9% of pathogenic cysts, such as Giardia. A Prefilter is
installed below the Cyst filter to remove sediment and organic contaminants.
Please carefully read the following instructions for maximum performance of your Katadyn
Exstream personal water purification system. Failure to follow the instructions found in this manu-
al may result in unsafe drinking water.
