Katadyn BeFree Gravity Filter System \u2013 Reliable Water Treatment Without External Power<\/h3>\n

The Katadyn BeFree Gravity Filter System<\/strong> provides safe and efficient drinking water treatment without pumps or electricity. Filtration is powered solely by gravity<\/strong>, making the system exceptionally low-maintenance, quiet, and reliable\u2014ideal for emergency situations, outdoor use, temporary camps, or off-grid water supply. <\/p>\n

At the core of the system is the EZ-Clean Membrane\u2122<\/strong>, a hollow fiber filter with a pore size of 0.1 microns <\/strong>that reliably removes bacteria, cysts, and sediment from the water. With a flow rate of up to 2 litres per minute<\/strong>, filtered water is available within a short time. The integrated water bag features a viewing window with a measuring scale<\/strong>, allowing the water level to be checked easily. <\/p>\n

The durable water bag folds down for compact transport. A sturdy carrying and hanging strap allows safe transport <\/strong>from the water source and secure suspension<\/strong> from trees or other suitable structures. The removable outlet hose features a quick-connect fitting and an automatic shut-off valve, significantly reducing the risk of cross-contamination during refilling. <\/p>\n

Filter cleaning is simple and suitable for field use. The EZ-Clean Membrane\u2122 is cleaned by shaking or swirling it in clean water<\/strong>, without the need for tools or additional equipment. Depending on water quality, the filter has a service life of up to 1,000 litres.<\/strong> <\/p>\n

Filtered water can be stored in separate containers, bottles, or water bags. For long-term storage, additional water preservation is recommended to prevent microbial growth. <\/p>\n
