Katadyn BeFree AC Bottle 0.7L Slate Blue
one bottle instead of a thousand

Buying bottled water abroad because you do not trust the tap? One membrane manages up to 1'000 litres – two thousand half-litre bottles from the kiosk you no longer need.

Buy the Katadyn BeFree AC Bottle 0.7L Slate Blue – refill instead of buy

The Katadyn BeFree AC Bottle 0.7L in slate blue is a rigid drinking bottle with an integrated water filter for travel, everyday use and day trips. 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. That lets you drink from the tap where you otherwise would not – and one membrane manages up to 1'000 litres. Slate blue is the series colour also carried by the BeFree AC 0.5L soft flask.

1'000 litres – what that means against single-use bottles

The membrane’s capacity is up to 1'000 litres. Converted to standard half-litre bottles that is around two thousand of them that do not have to be bought, carried and disposed of. For travellers in regions where the tap water is not trusted, that is the real line item: buy two or three bottles a day and the purchase pays for itself within a few weeks – while you carry considerably less along the way.

Slate blue – the colour that also comes as a soft flask

Slate blue is carried not only by the AC Bottle but also by the BeFree AC 0.5L soft flask. If you use both formats – the rigid bottle for everyday life, bike and travel, the collapsible one for fast, light trips – you end up with a matching set. That is practical less for looks than for sorting: two bottles of the same brand in the same colour visibly belong together when several people in a household have their own drinking bottles.

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.

Slate blue – and when another format fits better

Technically all four AC Bottle colours are identical; slate blue is the series colour also carried by the BeFree AC 0.5L soft flask, so the two combine into a set. Regardless of colour: if you want the empty bottle to disappear into your pack, a BeFree AC soft flask that rolls up serves you better. And if you fill several bottles at once in camp or prepare cooking water, choose a BeFree Gravity, where gravity does the work.
