Katadyn BeFree AC Bottle 0.7L Misty Red
drink without stopping

Anyone drinking while riding or running has one hand free – not two. The flip-top cap opens with that one hand, and the water is still filtered.

Buy the Katadyn BeFree AC Bottle 0.7L Misty Red – drink on the move instead of stopping

The Katadyn BeFree AC Bottle 0.7L in misty red is a rigid drinking bottle with an integrated water filter designed for use in motion: the flip-top cap opens with one hand, the textured outer surface keeps the body secure in the hand even when wet, and at 75 millimetres outer diameter the bottle fits common bike bottle cages. Filtration is two-stage: the EZ-Clean Membrane at 0.1 µm retains bacteria, protozoa, sediment and microplastics, while the activated carbon reduces chlorine along with taste and odour compounds.

Operation when the other hand is busy

Why the cap decides whether the bottle gets used

A filter bottle only helps if you actually use it – and in daily life that often fails on small things. A screw cap needs two hands: one on the bottle, one on the lid. On a bike, with poles in your hand or while running, that second hand is not free, so you simply drink later. The AC Bottle’s flip-top cap solves this: flip open, drink, flip shut – all with the same hand that holds the bottle. Added to that is the textured outer surface that grips even with wet or sweaty hands, and an integrated loop that lets you clip the bottle to the outside of your pack with a carabiner.

Misty red – visible where other things disappear

A drinking bottle is constantly being put down: next to the stove, in the tent porch, on a picnic table, in the side pocket of someone else’s pack. Dark colours reliably vanish in the process – especially at dusk or among leaves. Misty red is the most conspicuous of the four colour variants and makes the bottle recognisable from several metres away. If you travel in a group there is a further benefit: identical bottles cannot be mixed up when everyone carries a different colour.

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 safe – in a hotel, while travelling, at the office. 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.

Four colours, one product – and when the soft flask pays off more

The AC Bottle comes in smoke, misty red, moss green and slate blue. Technically all four are identical: same membrane, same carbon stage, same weight. Misty red is the most visible variant – useful if the bottle is put down often or several people in a group carry the same model. If, on the other hand, every gram counts and you want the empty bottle to disappear into your pack, a BeFree AC soft flask that rolls up serves you better.

Who is the Katadyn BeFree AC Bottle 0.7L Misty Red for?

The AC Bottle in misty red is for anyone who drinks on the move rather than stopping – cyclists and bikepackers, day hikers with poles, groups where everyone carries their own colour, and travellers facing chlorine taste in hotel water.

Frequently Asked Questions

Frequently Asked Questions – Katadyn BeFree AC Bottle 0.7L Misty Red

Answers around the Katadyn BeFree AC Bottle 0.7L Misty Red – from the flip-top and bottle cages to activated carbon, cleaning and Swiss shipping.

Can the Katadyn BeFree AC Bottle be opened one-handed?
Yes. The flip-top cap is flipped open, not unscrewed – which works with the same hand that holds the bottle. That is exactly what matters when you want to drink on a bike, with trekking poles, or while running.
Does the bottle fit a bike bottle cage?
Yes. The outer diameter is 75 millimetres, the common size for bike bottle cages. The rigid format was developed precisely for that – a BeFree soft flask does not fit there.
What does the «AC» in the name stand for?
AC stands for activated carbon. It forms the second filter stage behind the membrane and reduces chlorine along with taste and odour compounds. It has no bearing on microbiological safety – that is the membrane’s job.
How long do the membrane and the activated carbon last?
The EZ-Clean Membrane is rated for up to 1'000 litres, the activated carbon for around 200. Both figures depend on water quality: the more suspended and dissolved matter in the raw water, the sooner the capacities are reached.
Does misty red differ technically from the other colours?
No. Smoke, misty red, moss green and slate blue are identical apart from the colour – same membrane, same carbon stage, same weight, same dimensions. Misty red is simply the most visible variant.
What water quality does the bottle need?
Clear to slightly turbid water. Heavily silty or sediment-laden water clogs the hollow fibres quickly. In such cases let the water settle in a container first or pre-filter it coarsely.
How do I clean the filter?
Hold it in clean water and shake it vigorously – the deposited particles come off the hollow fibres and the flow is back. No backflush syringe or other tool is needed.
What is the loop on the bottle for?
For a carabiner. It lets you attach the bottle to the outside of a pack, a bike frame or a tent frame – useful when the main compartment is full or the bottle should stay within reach.
What happens if the filter freezes?
Freezing residual water can damage the hollow fibres without this being visible from outside. A filter that has frozen through should not be used further. Store the bottle frost-free and take it into your sleeping bag on winter trips.
How fast does Swiss-Sale.ch ship the Katadyn BeFree AC Bottle 0.7L?
Orders placed before 17:00 usually ship the same working day. We send with Swiss Post, and delivery within Switzerland takes 1–2 working days. Orders from CHF 100 ship free of charge.
Why buy the Katadyn BeFree AC Bottle from Swiss-Sale.ch?
Swiss-Sale.ch is an official Swiss dealer for Katadyn. You get fast shipping from a Swiss warehouse (no customs, no waiting), personal advice on the right format, and warranty handling directly in Switzerland.
What should I watch out for in use?
Keep the raw and clean water sides separate: if the drinking cap touches unfiltered water or the outside of the bottle, the filtration is void. Let the bottle dry openly after use before stowing it closed.
