Katadyn BeFree User Manual Download Page 2

Using the Katadyn BeFree™ improperly or drinking untreated water can result in 

exposure to harmful microorganisms and an increased risk of diseases. Reduce 

your risk of becoming sick by following the warnings and instructions in this 

manual and by educating yourself on backcountry/travel illness prevention.  

YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY AND THOSE IN YOUR 

GROUP. PLEASE USE GOOD JUDGEMENT.

Improper use of the Katadyn BeFree™ or use of a damaged or contaminated 

EZ-Clean Membrane™ expose you to harmful microorganisms and increase 

your risk of contracting a gastrointestinal illness. Read this entire manual before 

assembling or using the Katadyn BeFree™ and follow all instructions carefully. If 

you have any questions, contact Katadyn North America at 1-800-755-6701 or 

email us at [email protected] or visit our website at www.katadyn.com

 - The Katadyn BeFree™ does not remove viruses.

 - Never use the Katadyn BeFree™ to filter seawater or brackish water or 

chemically contaminated water, such as water from mine tailing ponds or 

near large agricultural operations. The Katadyn BeFree™ does not make 

drinkable water from these sources and does not remove chemicals and 

radioactive materials or particles smaller than 0.1 microns.

 - Do not use in freezing conditions (a frozen EZ-Clean Membrane™ could lead 

to microorganism bypass, resulting in illness)

 - Improper threading of cap to the Hydrapak

®

 SoftFlask™ could cause fluid 

leakage and result in illness.

 - Do not hold or squeeze the EZ-Clean Membrane

TM

 with your hand while 

opening or closing the Katadyn BeFree

TM

 (as showing in the diagram on the 

next page). Carefully hold the top part of the flask when opening or closing 

the Katadyn BeFree

TM

, allowing the EZ-Clean Membrane

TM

 to rotate freely 

inside the flask. Holding or squeezing the EZ-Clean Membrane

TM

 while 

opening or closing the Katadyn BeFree

TM

 could result in damage or breakage 

to the filter membrane, thus compromising/damaging the filter (which could 

allow harmful microorganisms to bypass the filter, leading to illness).

IMPORTANT SAFETY MESSAGE

WARNINGS

WARNINGS

Read before using Katadyn BeFree™

When you travel abroad, camp or backpack, you run the risk of illness ranging 

from the inconvenience and discomfort of diarrhea to more serious illnesses 

caused by protozoan cysts (i.e., Giardia, Cryptosporidium), viruses and 

bacteria.

The microorganisms that cause these diseases are often found in the food and 

water you consume.

Lakes, rivers, streams and the local water supply may also be contaminated.

To minimize the risk of contracting these illnesses, we suggest that you consult 

with your physician, state health department or travel clinic 4-6 weeks before 

you depart.

And while you are traveling, make sure that prepared food is thoroughly cooked 

according to its specified instructions. Select non-cooked foods (fruits, nuts, etc.) 

that have intact shells or skins, and always sanitize your hands properly before 

peeling the food. Wash your hands with soap and warm water thoroughly and 

often (and use hand sanitizer), especially before you eat or prepare food. Also, 

in groups encourage everyone to wash their hands frequently.  Microorganisms 

can spread to communal gear from one group member not sanitizing their 

hands properly. Do not share personal items (i.e. lip balm, eating utensils, 

toothbrushes, water bottles or bite-valves on hydration bladders). Make sure all 

food is properly prepared and thoroughly cooked. Filter all drinking water with 

your Katadyn BeFree™, including water used for brushing teeth, washing your 

face, etc. according to the instructions in this manual.

If there is any risk of viruses in the water, use an EPA-registered disinfectant such 

as Katadyn Micropur Tablets in combination with the Katadyn BeFree™  (Note: 

Follow all instructions for proper use of Micropur and wait the appropriate 

treatment time) or boil your water (must bring to a rolling boil for approx. 1 

minute) (Note: The Katadyn BeFree™ does not remove viruses).
