The Katadyn BeFree Gravity 6L is a hands-free water filtration system scaled for small groups and family camping trips where a single fill needs to serve multiple people. Fill the 6-liter collapsible bag from any stream, lake, or river, hang it from a branch, pole, or anchor point, and let gravity filter your water while you set up camp, cook, or rest. The 0.1 micron EZ-Clean hollow fiber membrane filters out sediment and fine particles at up to 2 L/min flow with a total capacity of up to 1,000L. The collapsible bag stores flat when empty so it adds minimal bulk to a group pack, and setup requires no assembly or tools. To clean, simply shake or swish the filter element in water to restore full flow. No backflushing equipment required. BPA-free throughout and designed for group camping, family trips, and base camp use, the BeFree Gravity 6L handles drinking and cooking water needs for 3 to 5 people with ease. Pair it with the BeFree Gravity Upgrade Kit to route filtered water directly into any standard water bottle or hydration reservoir. Whether you are car camping, base camping, or building out an emergency water supply, the BeFree Gravity 6L is the reliable, no-fuss solution. Trusted by Katadyn since 1928.
