Katadyn BeFree AC Bottle 0.7L Smoke
the filter bottle that also works day to day

A soft flask tips over on the table and fits no bottle cage. This one stands up, sits in a bike cage and still filters – in understated smoke grey.

Buy the Katadyn BeFree AC Bottle 0.7L Smoke – a filter in bottle format

The Katadyn BeFree AC Bottle 0.7L is a rigid drinking bottle with an integrated water filter – making it the most everyday-capable design in the BeFree range. Instead of a collapsible soft flask, this is a dimensionally stable polypropylene bottle that fits common bike bottle cages and cup holders. Filtration is two-stage: the EZ-Clean Membrane with its 0.1 µm pore size retains bacteria, protozoa, sediment and microplastics, while the activated carbon downstream reduces chlorine along with taste and odour compounds. The Smoke variant is the restrained smoke grey of the colour range.

Smoke – the understated variant

Of the four AC Bottle colours, Smoke is the most restrained: a neutral smoke grey that looks like outdoor gear neither on a desk nor on a bike. With a filter bottle that is an argument in itself, because it is rarely used only on the trail. If you carry the bottle daily to the office, on the train or to the gym and mainly need the filter function when travelling or hiking, a neutral colour serves you better than a signal shade.

Chlorine taste – the everyday benefit of the activated carbon

The second filter stage targets not pathogens but taste. Activated carbon binds free chlorine and organic compounds that can give tap water a distinct aftertaste depending on region and pipe age. That is why the AC Bottle also makes sense where the water is microbiologically completely safe – in a hotel, a holiday home, a city. The carbon stage is rated for around 200 litres; after that the membrane carries on, managing up to 1'000 litres.

What the filter does – and what it does not

The 0.1 µm membrane retains bacteria, protozoa, sediment and microplastics. Viruses are smaller and pass through – in regions with that risk you need additional chemical disinfection or UV treatment. Heavy metals and salt are not removed. The bottle is intended for clear to slightly turbid water; heavily silty water clogs the membrane quickly and should be left to settle or pre-filtered first.

AC Bottle or AC soft flask – the format decides

Both variants filter identically: same EZ-Clean Membrane, same 0.1 µm, same carbon stage. The difference is the vessel. The 0.5L and 1.0L soft flasks weigh less and roll up when empty – ideal when every gram counts and packed size is tight. The AC Bottle weighs 95 grams but stays dimensionally stable, stands on a table, fits a bike bottle cage and opens one-handed. If you use the bottle not only on the trail but day to day, choose the rigid format.
