Best BeFree Gravity Water Filtration System 10L Gravity Filters

Jump to: Our Verdict / Features / Specifications

Lightweight, hands-free water filtration for larger groups.

Katadyn says:

The sleek, foldable Katadyn BeFree Gravity 6L filter system uses gravity to get the freshest, cleanest water you can trust. The heart of the BeFree Gravity 6L is the EZ-Clean Membrane offering a fast flow rate of up to 2 liters per minute. The water passes through a hollow filter which safely removes bacteria, cysts and sediment with its pore size of .01 micron (0.0001 mm). Thanks to the water level indicator window, it is clearly visible when refilling is necessary. The practical carrying strap allows you to haul a full filter back to camp effortlessly, where it can be hung in a nearby tree. The ouput hose can easily be removed using a quick-release valve with automatic flow-stop, to prevent contact with contaminated water when refilling.

The capacity of the filter is up to 1000L, depending on water quality. To clean the EZ-Clean Membrane, just shake or swish it in water in the filed or at home.

Filtered water can be stored in a separate container, bottle or hydration bladder (using included quick connect fittings). The opening of the container, bottle or bag for filtered water should be small as possible to prevent dirst from getting in. If the filtered water is not to be used on the same day, use Katadyn Micropur tablets to preserve it.

Our Verdict

The Katadyn BeFree is now my filter of choice for when I’m hiking solo, and I’m pleased to say that if you are hiking in larger groups, this gravity filtration system is an ideal choice.

The reason I love my BeFree when I’m solo hiking is that the flow rate is so much better than other brands on the market and the 6l gravity filter is just as impressive, filtering up to 2 litres a minute.

Its very straightforward to use, simply fill the 10l dirty water bag, and hand it up with the straps provided.
