The Katadyn BeFree AC Bottle 0.7L is a filtered water bottle built for the way modern travelers actually move - commuting, traveling internationally, running errands, and hitting the trail, often all in the same day. Unlike the collapsible softflask BeFrees, the 0.7L features a rigid, hard-sided bottle designed to fit standard cup holders and bike bottle cages, making it as at home on a daily commute as it is on a trail. Its 2-stage filtration system combines a 0.1 micron hollow fiber EZ-Clean membrane with activated carbon to remove bacteria, protozoa, and microplastics while simultaneously reducing chlorine, odors, and bad taste. This makes it uniquely suited for tap water sources, hotel sinks, airport fountains, and urban refill points - not just backcountry streams. The bottle fits in carry-on bags, side pockets, and backpack pockets. Empty it before security, refill at the fountain on the other side, and go. Maintenance requires no tools or backflushing - just shake or swish in water to restore full flow. BPA-free and built for high-frequency daily use, the BeFree AC Bottle 0.7L is the filtered water bottle that keeps up with a life that does not slow down.
