Katadyn Gravity BeFree 6L Water Filter

The Katadyn Gravity BeFree 6L Water Filter is a sleek, foldable gravity system designed to provide fast, reliable drinking water for camping, hiking, and backcountry travel.

Using gravity instead of pumping, this system delivers clean water with minimal effort—simply fill the 6-liter reservoir, hang it from a tree or branch, and let the filter do the work. Its hollow fiber filter with a 0.1-micron pore size safely removes bacteria, cysts, and sediment, ensuring water you can trust wherever your adventure takes you.

At the core of the system is Katadyn’s EZ-Clean Membrane™, which maintains a rapid flow rate of up to 2 liters per minute and can be cleaned easily in the field by shaking or swishing it in water—no tools or backflushing required. A built-in water level indicator window lets you quickly see when it’s time to refill, while the practical carrying strap makes transporting a full bag back to camp effortless.

The Gravity BeFree 6L also features a quick-release hose with an automatic flow-stop valve to prevent contact with contaminated water during refills. Filtered water can be directed into bottles, hydration bladders, or separate containers using the included quick-connect fittings. With a total filtration capacity of up to 1000 liters (depending on water quality), this compact and lightweight system is ideal for solo trips or small groups looking for a simple, dependable water purification solution. If the filtered water is not to be used on the same day, use Katadyn Micropur tablets to preserve it.

Q: What are Katadyn BeFree bottles and Steripen UV purifiers used for?
A: Both systems provide safe, clean drinking water while on the trail, traveling, or fishing in remote areas. The Katadyn BeFree uses a physical filter to remove bacteria and protozoa, while the Steripen uses UV light to neutralize microorganisms, offering fast, reliable purification.

Q: How does the Katadyn BeFree water filter work?
A: The BeFree uses a 0.1-micron hollow fiber filter that physically removes harmful organisms such as Giardia and Cryptosporidium. Simply fill the bottle from a freshwater source, squeeze, and drink — no pumping or chemicals required.

Q: What are the advantages of the BeFree system?
A: It’s lightweight, compact, and easy to clean. The collapsible bottle design makes it ideal for backpacking or wading trips, and the fast flow rate means you can hydrate quickly without waiting for tablets or UV treatment.

Q: How does the Steripen UV purifier work?
A: The Steripen uses ultraviolet light to destroy the DNA of bacteria, viruses, and protozoa, preventing them from reproducing. It purifies a full liter of water in under 90 seconds — ideal for travelers and anglers who want safe water without filters or chemicals.
Q: Is UV purification effective on cloudy or sediment-filled water?
A: UV purifiers like the Steripen work best in clear water. If water is cloudy, pre-filter it through a cloth, coffee filter, or sediment screen before using the UV light to ensure full effectiveness.

Q: How long do the filters and UV lamps last?
A: The Katadyn BeFree filter lasts up to 1,000 liters, depending on water quality, and can be cleaned easily by shaking or swishing. Steripen lamps typically last for 8,000 activations, providing years of reliable use.

Q: Do these systems remove chemicals or heavy metals?
A: No. The BeFree and Steripen systems target biological contaminants. For chemical removal or taste improvement, pair them with activated carbon filters or bottled water in areas with known pollution.
