Katadyn BeFree Gravity 10L



The Katadyn BeFree Gravity 10L offers the maximum ease of filtering water for a group: Just fill and hang - clean drinking water will be available without pumping.

The sleek, foldable Katadyn BeFree Gravity 10L filter system uses gravity to get the freshest, cleanest water you can always trust. The heart of the BeFree Gravity 10L is the EZ-Clean Membrane, offering a fast flow rate of up to 2 liters per minute. The water passes throught a hollow fiber filter which safely removes bacteria, cysts and sediment with its pore size of 0.1 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 effortleslly, where it can be hung in a nearby tree. The output 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 the water quality. To clean the EZ-Clean Membrane, just shake or swish it in water in the field 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 as small as possible to prevent dirt from getting in. If the filtered water is not to be used on the same day, use Katadyn Micropur tablets to preserve it.

NOTE: Pot is not included, it is for demonstration purposes only.
