Product details

The Katadyn Gravity BeFree™ 6.0L water filter uses the concept of gravity. Simply fill it up, hang it, and enjoy clean drinking water outdoors without needing to squeeze or press. It's ready to use whenever you need it.
It features clear scale markings, a convenient strap for hanging and carrying, and an included adapter kit that allows you to directly fill a hydration bladder with filtered water, offering versatile and convenient use.

Ultra-micron filtration: Filters down to 0.1 microns, removing bacteria, cysts, sediment and microplastics; it does not remove viruses.
High flow rate: A maximum flow rate of 2 liters per minute means no more waiting for water.
Easy-clean filter cartridge: When the flow rate drops, fill the pouch with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water to clean it; untreated source water can be used. However, the outlet (mouthpiece) must not touch untreated water; keep it clean after cleaning. Hold the pouch end lightly while swishing — do not squeeze the filter itself.
Versatile use: Suitable for all outdoor activities, such as hiking, fishing, boating, family camping, group events, etc.
Lightweight and portable: Lightweight design ensures access to clean water anytime during your travels.
Convenient adapter: The adapter kit connects directly to a hydration bladder for easy refills.
Hanging storage: The adapter kit allows for convenient hanging storage of the soft tube.
Recommended for groups: Its capacity is suitable for group use.
Wide mouth design: The wide opening makes filling with water more convenient.
Collapsible water bag: A soft, lightweight, and collapsible water bag for easy storage.
Included shoulder strap: Can be hung on a tree or carried over the shoulder for more flexible use.
Transparent scale window: Easily monitor the remaining volume.
Water flow control valve: Built-in water flow control valve for precise and easy water flow management.
Product includes: Water bag body, BeFree filter cartridge, soft tube, water flow control valve, adapter kit, shoulder strap, storage bag.

EZ-CLEAN MEMBRANE FILTER Hollow Fiber Filter Cartridge Diagram

0.1 micron filtration can remove bacteria and protozoan cysts. Per the manufacturer's manual, it reduces bacteria (Klebsiella terrigena) by 99.9999% and protozoan cysts (Giardia and Cryptosporidium) by 99.9%, which the maker states meets the U.S. EPA microbiological water purifier standards for those two groups; it does not remove viruses.

Thoughtful Design and Efficient Filtration

Combining convenient adapters, hanging storage, water flow control, and efficient filtration, the 0.1 micron filter pore size effectively blocks bacteria. Coupled with a high flow rate of 2 liters per minute, you can quickly, safely, and conveniently refill and use water outdoors.

Filter Cleaning Made Easy

When the flow rate drops, fill the pouch with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water to clean it; untreated source water can be used. However, the outlet (mouthpiece) must not touch untreated water; keep it clean after cleaning. Hold the pouch end lightly while swishing — do not squeeze the filter itself.

Your All-Around Outdoor Partner: Economical and Eco-Friendly

Suitable for all outdoor activities, it helps you say goodbye to expensive bottled water, making it easy and practical.

Proper Use and Maintenance

After use, please clean thoroughly with clean water and allow all components to air dry completely to prevent mold.

Filter Cartridge Usage Precautions

Do not rinse the EZ-Clean Membrane filter cartridge horizontally under tap water. When opening or closing the Katadyn BeFree water filter, do not hold or squeeze the EZ-Clean Membrane filter cartridge with your hands, as this will damage the hollow fiber membrane within the filter.

Filter Cartridge Usage Precautions

Do not touch the hollow fiber membrane of the filter cartridge with tools or fingers.

FAQ

How many people is the BeFree Gravity 6.0L suitable for?

Capacity is 6.0 liters. The manufacturer's product page lists the group size as '1, >10, 2-5' for the 6L and 10L together, with no single recommended number of people, at up to 2 L per minute. It suits mountaineering, fishing, boating, family camping and group activities.

Can the BeFree Gravity 6.0L connect directly to a hydration bladder?

Yes. The product description lists an included adapter kit that lets you put filtered water straight into a hydration bladder. It also comes with a soft hose, flow control valve, shoulder strap and storage bag.

Where does the filtered water go with the BeFree Gravity 6.0L?

The manufacturer says you can fill another container, bottle or pouch (using the included quick-connect fitting). The receiving container should have a small opening to keep dirt out. The outlet hose has a quick-release valve that can be detached when refilling to avoid contact with dirty water.

Can the BeFree Gravity 6.0L filter viruses?

The product description does not list viruses. The listed targets are bacteria, protozoa, cysts, sediment and microplastics, with a 0.1 micron filtration pore size. It should not be relied on for virus protection; if virus contamination is a concern, the water needs separate treatment.

What does the BeFree Gravity 6.0L filter out?

The cartridge is a 0.1 micron hollow fiber membrane. The product description lists removal of bacteria, protozoa, cysts, sediment and microplastics, at up to 2 L per minute.

How long does the BeFree Gravity 6.0L cartridge last?

The specification lists a cartridge life of about 1,000 liters, depending on source water quality. When the flow rate drops noticeably, first clean the cartridge: fill the pouch with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water to clean it; untreated source water can be used. However, the outlet (mouthpiece) must not touch untreated water; keep it clean after cleaning. Hold the pouch end lightly while swishing — do not squeeze the filter itself.

How do I clean the BeFree Gravity 6.0L cartridge when the flow slows down?

Fill the pouch with water, reattach the cartridge and shake it vigorously, or hold the cartridge and swish it in water to clean it; untreated source water can be used. However, the outlet (mouthpiece) must not touch untreated water; keep it clean after cleaning. Hold the pouch end lightly while swishing — do not squeeze the filter itself. Do not rinse it horizontally under tap water, squeeze it by hand, or touch the hollow fiber membrane with tools or fingers.

How do the BeFree Gravity 3L, 6L and 10L differ?

Capacities are 3, 6 and 10 liters. On group size, the manufacturer's product page lists 2–5 people for the 3L, and no single recommended number for the 6L and 10L. The cartridge specs are the same: 0.1 micron and about 1,000 liters.

Can the BeFree Gravity 6.0L be used in freezing conditions?

No. The manufacturer's manual warns against using it in freezing conditions, because a frozen membrane could let microorganisms bypass the filter and cause illness. If the cartridge has frozen, been dropped hard or may be damaged, stop using it and run the manual's integrity test: with the membrane wet, try to blow air through the output hose; if you cannot blow through, the fibers are intact, and if you can, the fibers are broken, so stop using it and replace the cartridge.

How should the BeFree Gravity 6.0L be prepared for long-term storage?

Before long-term storage, follow the long-term storage procedure in the manufacturer's manual: clean and disinfect the filter, hoses and bag, then disassemble all parts, rinse them with filtered or treated water, air dry them completely, reassemble and store them in the carry bag; the manual has the detailed steps. When taking it out of long-term storage, flush it with 2 liters of filtered or treated water to remove stale taste. Do not put the membrane or filter cap in a dishwasher or microwave.

What does the manual say about viruses and chemically contaminated water for the BeFree Gravity 6.0L?

The manufacturer's manual states that the BeFree does not remove viruses, nor chemicals, radioactive materials or particles smaller than 0.1 microns, and that it must never be used on seawater, brackish water or chemically contaminated water (for example water from mine tailing ponds or near large agricultural operations). If the water raises these concerns, use a reliable drinking water source instead, or treat it separately.

Can the BeFree Gravity 6.0L filter cloudy water?

The manufacturer's two documents differ: the fact sheet says 'Also for cloudy water', while the product page lists the water source type as Clear Water. The manual's advice is to always use the best fresh water source available and to avoid still water or water in areas of heavy human or animal use, to extend membrane life; when the flow slows, clean it by shaking or swishing, and replace the cartridge if that does not restore the flow.
