The Katadyn Pocket Water Filter is made of heavy duty materials is ideal for long lasting continuous use even under extreme circumstances. The silver impregnated ceramic element is effective against bacteria and protozoa. The Katadyn Pocket is the only water filter with a 20 year warranty.

The Katadyn Pocket Microfilter meets industry standards for reduction of bacteria (99.9999%) and protozoan cysts like Legionella, Giardia and Cryptosporidium (99.99%). The Pocket is Katadyn’s most rugged filter. Professionals trust its longevity. The Pocket is ideal for 1 to 4 persons while trekking, on journeys and on expeditions. Like the other Katadyn filters, the Pocket makes an excellent survival tool. There is a sense among several people that something catastrophic is about to take place and depending on who you talk to some believe it will be at the level of an extinction event or at least where organized governments no longer exists. People are stocking up on things like gold, but can you drink gold in a time of trouble? All the money in the world cannot buy a carrot when there is none left on the shelf.

  • The Katadyn Pocket is the first portable water filter. It is a classic and still a leader.

  • Made from top-quality, durable materials. This is why the Pocket is suitable for the toughest of conditions and is the first choice for extreme adventurers like Mike Horn.

  • The tried and tested ceramic depth filter removes bacteria, protozoa and other disease-causing agents. The principle: The micro-organisms cannot pass through the mini pores of the filter ceramic (0.2 microns) because of their size (greater than 0.2 microns = 0.0002 mm).

  • Unlike disposable filters, the ceramic can be cleaned several times - even in the field.

  • Improved, round pump handle for better ergonomics and an outlet hose which can be attached to water containers with a simple clip.


  • Top-quality, durable materials > unparalleled quality with a 20 year guarantee

  • Cleanable ceramic filter element > not only for clear but also for very cloudy water / can be used hundreds of times (not a disposable filter)

  • Few movable parts > simple maintenance

  • Long lasting > requires minimal maintenance

  • Improved hand ergonomics > even easier to pump

  • Measuring gauge supplied > indicates when the filter element should be changed

Katadyn Pocket Product Set up  (download manual)
The Pocket requires minimal set up. For best results, try out the Pocket before first field use to familiarize yourself with its operation.

1) Connect Hoses: Push the hose float on to the input hose (hose with prefilter). Position the float approx. 2 inches from prefilter. Attach the input hose to the input barb on the pump base. Push the bottle clip on to the output hose. Attach the output hose to the output barb.

2) Flush System: Important: Before first use, flush system by pumping approximately 0.5 litres of water through the unit to remove harmless ceramic dust. See following section on Normal Operation on how to filter water.

Normal Operation
1) Place input hose in untreated water source. Adjust the float to keep prefilter off the bottom
and away from sediment.
2) Attach the bottle clip on the output hose on to a clean water container*. (Figure 2 3)
3) Hold the filter upright and begin pumping the handle in a slow, steady manner. Make sure
the input hose is not kinked.
4) After filling water container with filtered water, remove bottle clip from container and input
hose from water source. Continue pumping to remove remaining water from pump body.
5) Store the unit in the carry bag. To prevent the possibility of cross contamination remove the output hose with the clip and store separately in the re sealable bag inside the carry bag.
*Note: Before each use, pump and discard a small amount (0.2 litres) of water to remove stale taste.

Field Performance Tips
The Katadyn Pocket is designed to remove bacteria and protozoan cysts such as Legionella, Giardia and Cryptosporidium. To extend ceramic life, always use the best water source available. Keep the input prefilter clean and off the bottom. In heavy sediment conditions, wrap a coffee filter or bandanna around the input prefilter. Where possible, place untreated water in container and wait for sediment to settle out until water appears clear then filter from
water above the sediment.

Maintain your Katadyn water system to keep it operating smoothly.
1) If handle is hard to push:
Clogged filter pores. If the filter pores of the ceramic are clogged, the ceramic needs to be cleaned. Never use force when pumping. Remove the element by turning it counterclockwise as far as it will go and lifting it from the housing. Regenerate the ceramic by brushing under running water with the supplied cleaning pad until the light, original ceramic colour appears again. When reassembling hold output barb towards logo on pump housing and turn clockwise as far as it will go while pushing down.
2) Lubricate pump handle o ring. Silicone lubricant is provided with your new unit. Remove handle collar and handle. (Figure 1 1) Clean excess build up from black rubber o ring on bottom of handle. Place a small amount of silicone lubricant all the way around the o ring. Re assemble.
3) If unit pumps easily, but no water flow: Make sure prefilter is submerged.
Make sure that input hose is not blocked or pinched. Hold the filter vertically until water flows.
4) Prefilter: Rinse the prefilter in water to remove any particles that may be caught in the strainer.
5) Storage: Your Katadyn water system comes with a carry bag for storage. To prevent the
possibility of cross contamination remove the output hose with the bottle clip and store
separately in the re sealable bag inside the carry bag.

Long Term Storage (After Your Trip Is Over)
Store the Pocket filter as follows:
1) Unscrew the pump base and clean the ceramic element by brushing with the supplied cleaning pad. Allow to air dry completely.
2) Rinse the blue plastic sleeve and remove any dirt.
3) Lubricate the o rings and the threads of the filter element and the pump base.
4) Re assemble the filter.
5) Wrap input hose around body and store Pocket inside the carry bag.
Note: When removing unit from long term storage, flush the system with one liter of water to
remove any stale tasting water.

Katadyn Ceramic Filter Capacity
Ceramic capacity depends on water quality. The dirtier the water the more often you will have to clean the element. This reduces the capacity of approx. 13’000 gallons (50’000 liters). If the gap of the measuring gauge fits over the ceramic it is time to replace the filter (Figure 2 3). Inspect the ceramic for cracks after cleaning, if you dropped the filter or if you had freezing temperatures. If the filter shows cracks it will no longer protect you from microorganisms.

Ceramic Filter Installation Instruction
1) Unscrew the pump base counter clockwise from the lower end of the filter housing and remove the plastic sleeve by pulling it downwards.
2) Unscrew the handle collar on the upper part of the ceramic element counterclockwise and
remove the pump handle. Lubricate o ring.
3) Remove new ceramic element from packaging
4) Insert pump handle into the new ceramic element and tighten the handle collar clockwise.
5) Push the plastic sleeve over the new ceramic element. Apply a drop of silicone lubricant to
the thread of the pump base. Tighten the pump base to the housing clockwise.
6) Flush ceramic element by pumping and discarding the first liter.

When You Travel Abroad, Camp or Backpack…
…you run a risk of illness ranging from the inconvenience and discomfort of diarrhoea to more serious illnesses caused by protozoan cysts (i.e., Legionella, Giardia, Cryptosporidium), viruses and bacteria. The microorganisms that cause these diseases are often found in the food and water you consume. Lakes, streams and the local water supply may be contaminated. To minimize the risk of contracting these illnesses, we suggest that you consult with your physician, state health department or traveler's clinic 4 6 weeks before you depart.

And while you are travelling…
• Make sure that prepared food is thoroughly cooked.
• Select non cooked foods (fruits, nuts, etc.) that have intact shells or skins, and clean your hands before peeling the food.
• Wash your hands with soap and water thoroughly and often, especially before you eat. Filter all drinking water with your Katadyn Pocket Water Microfilter.

The Katadyn Pocket Microfilter is an essential piece of outdoor equipment.

Should your Katadyn Pocket prove defective with in that period from the date of purchase, return it to the Katadyn retailer from whom it was purchased.
