How to Clean the Katadyn BeFree AC

Cleaning the BeFree AC Bottle

The BeFree AC Bottle is designed for quick and hassle-free cleaning—no backflushing or special tools required. Simply swish the filter in clean water to remove dirt and debris. Alternatively, fill the soft flask halfway with clean water, attach the filter and shake it thoroughly. Keep the cap closed during cleaning to protect the mouthpiece from contamination. Afterwards, discard the used water. Your BeFree AC Bottle is now clean and ready for your next mission.

Why regular cleaning helps

Sediment can slow the flow of a water filter. Regular cleaning helps the BeFree AC maintain a useful flow rate and keeps it ready for the next filling point. The right frequency depends on water quality and how often the filter is used.

Use the correct product guidance

The BeFree AC combines hollow fiber filtration with activated carbon. Follow the current instructions for the specific model and do not use aggressive tools or unapproved cleaning methods. Inspect the filter and bottle for visible damage before use.

Care after cleaning

Let the filter drain and store it as directed. Protect it from freezing temperatures, heat and sharp bends. If the filter remains slow after cleaning or shows damage, stop using it and check the appropriate replacement or service option.
