BeFree AC 1.0L Microfilter

Katadyn BeFree AC 1.0L Microfilter

A versatile, ultralight filter bottle that delivers clean, great-tasting water at up to 2 liters per minute with a two-stage filtration system that handles both pathogen removal and taste improvement in one compact package. The BeFree AC is the right tool for hiking, travel, and everyday hydration where you want clean water fast without carrying a separate filter and bottle.

Why We Carry It
It's the filter bottle we recommend for hikers and travelers who want a fast, easy-to-clean filtration solution that handles everything from backcountry streams to chlorinated tap water in one piece of gear.

Highlights

• Two-stage filtration with hollow fiber and activated carbon — The hollow fiber membrane removes protozoa and bacteria down to 0.1 microns while the activated carbon pad eliminates chlorine taste, chemicals, and odors. Use both stages for tap water or questionable sources, or skip the carbon for already clean mountain stream water.
• 2-liter per minute flow rate — One of the faster filter bottle flow rates available. Fast enough to fill bottles for multiple people at a water source without a long wait between turns.
• BeFree EZ Clean Membrane — Clean the filter by shaking or swishing in water without additional tools or disassembly. One of the more effortless field cleaning processes available in a filter bottle at this weight.
• Modular activated carbon pad — Remove it when the water source is already clean and delicious or add it back for tap water and treated water sources where taste improvement matters. A flexibility detail that extends the usefulness of one filter across multiple water source types.
• Integrated rugged handle — Clip it to a pack with a carabiner, pull it from a running vest pocket, or carry it by hand. A versatile carry option that works across different activity types without a separate bottle sleeve or attachment system.
• Robust flip cap — Keeps water in and contaminants out on active use without a separate cover to lose. Reliable closure for high-movement activities like trail running and cycling.
• 2.7-ounce weight — An ultralight filter bottle at a weight that justifies carrying it on any trip where clean water access is uncertain. Light enough for a running vest or a day hike without meaningful weight penalty.
• BPA-free TPU construction — A flexible, durable bottle material that handles compression and repeated use without cracking or leaching.
