Water filter cap Katadyn BeFree AC Flip Cap — compatible Katadyn, blue/white, 1 pc

Katadyn BeFree AC Flip Cap — compatible Katadyn, blue/white, 1 pc is a replacement flip cap with integrated activated carbon designed for use with Katadyn BeFree hydration systems. This cap serves as the user-replaceable interface between a soft collapsible reservoir and the BeFree hollow-fibre membrane, combining particulate and bacterial filtration with carbon-based taste and odor improvement. Supplied as a single blue-and-white unit, the cap is intended for outdoor, travel and everyday portable filtration where a compact, lightweight solution is required.

Advantages

The combined cap integrates filtration and dispensing into one compact component that keeps the system lightweight and easy to pack. The hollow-fibre membrane allows fast flow for convenient drinking and quick filling, while the activated carbon element helps reduce chlorine and unpleasant tastes and odors. The flip-cap design permits hygienic, one-handed access and reduces the risk of spills, and the overall construction is suited to backpacking, travel and emergency use where rapid deployment is needed.

Suitable for

• Day hikes and trail running where low weight and small pack size are important
• Travel to regions with uncertain tap water quality
• Emergency preparedness kits and evacuation bags
• Outdoor sports such as cycling, climbing or canoeing

Key specifications

• Filter type: Hollow-fibre microfilter membrane combined with an activated carbon component
• Contaminant reduction: Removes particulates and bacteria; activated carbon reduces chlorine and improves taste and odor
• Reservoir compatibility: Designed for use with soft, collapsible BeFree reservoirs
• Cap design: Flip cap for single-handed operation and spill reduction
• Portability: Lightweight construction suitable for backpacking and travel
• Flow characteristics: Fast flow rate for drinking and filling through the BeFree membrane
• Intended use: Single-user portable water filtration for outdoor and travel scenarios

How to use

Attach the flip cap to a compatible BeFree reservoir according to the reservoir and cap connection instructions. Fill the soft bottle from a suitable water source, close the cap and drink directly through the integrated mouthpiece or squeeze the reservoir to push water through the membrane and carbon component. Avoid filling from heavily sediment-laden sources without pre-filtering; allow large particles to settle or use a cloth pre-filter if necessary. The activated carbon element improves taste and odor but does not disinfect chemical contaminants; continue to follow any additional water treatment requirements based on local water quality.

Usage recommendations

After each use, rinse the reservoir and flush the cap and filter with clean water to clear debris. Allow components to dry partially with the cap open for storage to reduce microbial growth. Monitor flow rate and taste; replace the carbon element or membrane following Katadyn’s maintenance guidance or when performance declines.
