Whether you’re deep in the backcountry or just need clean water on the go, the BeFree AC 1.0L is built to keep up. Its durable double-layer flask is lightweight, compact, and easy to stash in your pack without taking up valuable space.
The 2-stage filtration system delivers clean, great-tasting water with a fast flow rate of up to 2 liters per minute. Filling up from a clear mountain stream? Skip the activated carbon and enjoy it straight from the source. Dealing with less-than-great tasting water? Add the activated carbon pad to help reduce unwanted tastes and odors.
A rugged integrated handle makes the BeFree AC easy to grab, carry, or clip to your pack with a carabiner, while the durable flip cap helps keep water where it belongs—even when the trail gets rough.
The proven BeFree EZ-Clean Membrane™ also makes field maintenance simple. No tools or complicated cleaning process needed—just shake or swish the filter in water to clear out debris and keep it flowing.
Lightweight, fast, and easy to maintain, the BeFree AC 1.0L is a solid choice when dependable water filtration matters.
