Water Filter Bottle Katadyn BeFree AC with Flip Cap — black

The Katadyn BeFree AC with Flip Cap — black is a portable water filter bottle that pairs a flexible, lightweight bottle with the BeFree AC cartridge and a flip cap for easy access. Designed for everyday carry, outdoor activities and travel, the bottle delivers on-demand filtration by forcing water through the replaceable cartridge. The compact design and single-handed flip cap make it practical for hiking, commuting or short trips where clean drinking water is needed quickly and with minimal fuss.

Advantages

The integrated BeFree AC cartridge provides mechanical filtration and active carbon treatment in a single unit, reducing particles and improving taste and odour. The bottle’s flexible construction and low weight allow it to be stored flat when empty and carried without adding bulk. The flip cap enables fast, splash-free drinking and keeps the spout protected from dirt. The cartridge is replaceable, so the bottle can be used repeatedly with new filter elements as needed.

Suitable for

• Day hikes and short backpacking trips
• Travel where tap water quality is uncertain
• Urban commuting and gym use
• Emergency preparedness and outdoor events

How to use

Fill the bottle from a natural source or tap, close the cap if required for transport, then open the flip cap and squeeze the bottle to push water through the BeFree AC cartridge and drink directly from the spout. Follow manufacturer guidance for priming the cartridge before first use and for the recommended replacement interval. Rinse the bottle and cap with clean water after each use and allow components to dry to limit biofilm formation when storing between uses.

Usage recommendations

Use the bottle with visibly clear water when possible; allow cloudy or sediment-laden water to settle or pre-filter through a cloth to extend cartridge life. Replace the cartridge according to usage and local water conditions, and store the bottle with the cap open in a dry place to prevent odour buildup.
