ÖKO, what exactly is it?
🧢 ÖKO is not just a simple water bottle.
The filter is screwed into the cap.
✋ You squeeze the water bottle.
The water passes through the filter.
⚡ Instant filtration.
Water is improved the moment you drink it.
🧪 Contaminants are left behind in the pores.
As in any water filtration system.
🚀 Powerful filtration technology available to the general public.
Developed from work carried out for NASA.
Based onelectroadsorption.
⚽ Olympique de Marseille.
Players drink tap water filtered with ÖKO,
on a daily basis to stay hydrated.
♻️ Direct consequence.
Fewer single-use bottles.
A concrete CSR approach linked to actual usage.
✨ A filter used by the elite of the sport.
For the general public.

Official Partner & Supplier of OM
All OM teams drink tap water that has been filtered through ÖKO filters.
A trusted choice: we don't provide random solutions to elite athletes who are monitored at the highest level.
2
Very economical to use
Tap water is one of the cheapest everyday resources.
ÖKO improves this already drinkable water at a very low cost,
without changing your habits or your water source.
3
Everywhere, simply, just by pressing
Whether at home or on the go,
ÖKO can be used anywhere, without electricity or complex installation.
The tap becomes your ally again... even when you're away from home.
Your hands allow you to squeeze.

COFRAC laboratories, for reliability
The performance of ÖKO filters is measured by COFRAC-accredited laboratories(
) according to strict protocols governed by the international standard ISO/IEC 17025.
A factual, rigorous, and transparent approach, without excessive promises.
The full reports are available on the Lab Tests page.
⚠️ Important information – visual demonstration
👁️ This video deliberately showsimpressive instant filtration:
Visibly very dirty water enters the filter
and immediately comes out clear.
This is the basic principle of ÖKO direct flow filtration.
⚡ The speed observed is normal.
The water is filtered at the precise moment you drink it,
with no reservoir, no storage, and no waiting.
💧 Unlike gravity-fed systems,
there is no standing water.
Clarity is therefore immediate and visible.
Tap water is normally clear and safe to drink.
In rare cases (construction work, network flushing),
it may temporarily appear brownish.
🧪 As with any water filter,
the result depends solely on what passes through the filter media.
⚠️ Any deliberate reproduction of extreme tests,
carried out knowingly to "test" the product,
will result in exceptional strain on the filter.
👉 ÖKO Europe accepts no liability for misuse.
✅ This demonstration is visual and illustrative only.
It does not represent standard everyday use,
but allows the immediate effectiveness of the system to be seen.
3 steps to understanding
01
Filter composition
The filter membrane is composed of a natural mineral fiber (pseudoboehmite AIOHH), antibacterial ions, and a microscopic sprinkling of activated carbon.
It is 8 mm thick and has more than 400 pores.
02
Mechanical filtration
Its pores are calibrated to 1.25 microns, mechanically blocking all particles greater than or equal to this size, such as sediments and impurities. This allows it to filter mud, for example.
03
Submicron filtration
When it comes into contact with water, the natural mineral fiber emits a positive charge field that surrounds the hollow volume of the pores. The water is thus stripped of submicron contaminants, which are attracted like a magnet to the membrane's retention surface. This is electro-adsorption.

Concrete action before anything else
🧢 What you buy at the beginning
You're not just buying a simple water bottle.
You're buying a complete reusable water bottle, designed to last:
the bottle, the filter cap, the straw protector, the carabiner,
and a filter already included to get you started.
👉 All these components are reusable over time.
👉 Only the filter needs to be replaced, nothing else.
💰 The cost in the first year (budgeted)
which is then stored for years.
👉 On average, this represents approximately €7 to €8 per month,
including bottle, cap, and filter.
👉 By adding a replacement filter from the outset,
you are at ease for approximately 12 months,
without surprises or emergency repurchases.
👅 When to replace the filter
When the taste or smell of tap water reappear,
This simply means that the filter is reaching the end of its capacity.
👉 At that moment, you rebuvez tap water,
exactly as before using ÖKO.
The water remains drinkable.
All you need to do is change the filter.
💧 What a filter actually does
An ÖKO filter can filter approximately 378 liters of water
on clear, drinkable tap water.
👉 This corresponds to an average of 2 liters per day,
or approximately 6 months of use,
but it always depends on what you actually drink.
📉 The cost in subsequent years
They are not replaced every time the filter is changed.
👉 In subsequent years, you only replace the filter.
based on your personal consumption.
Result: the monthly cost naturally decreases,
🔄 A simple gesture, without obligation
To replace it, simply unscrew/screw it back on.
⏱️ Less than 30 seconds,
without tools, without complicated handling.
Why does ÖKO use plastic?
- Food grade.
- Compressible and lightweight: thanks to this flexible material, you can easily squeeze and push water through the filter.
- Resistant and durable: designed to last for several years, withstanding both high temperatures and daily use.
- Taste and odor free: it preserves the natural, pure taste of your water.
- At the end of its life, your water bottle can be 100% recycled.

What do you think of our ÖKO filter bottle?
J’ai acheté la gourde OKO avant de partir en voyage et je suis très satisfait je filtres l’eau de montagne et de puits depuis une semaine vraiment efficace j’ai acheté le modèle 1L qui me convient parfaitement merci OKO 😉
J’utilise ma gourde OKO au quotidien en remplacement de mon ancien système (bâton de charbon) qui n’est pas assez efficace. Avec la gourde l’eau a un très bon goût, et je n’ai pas peur de m’intoxiquer avec métaux lourds, résidus médicamenteux, ou autre. Je suis très contente de cet achat en 1L et j’aimerais bien en avoir une en 650mL pour les occasions ou j’ai besoin de partir « plus légère ». Merciiii !
Un peu déboussolé par le fait de boire sans aspirer, j’ai eu du mal à m’habituer mais du coup l’eau est très très bonne et j’ai une grande confiance dans ce système de filtration donc et ben quand je l’ai plus ou que je l’oublie, elle me manque petit plus avec l’application qui vous rappelle de laver les embout et qui vous donne la date de changement du filtre. J’ai 650 ml qui convient très bien à mon sac, donc je peux l’emmener partout.
Après 2 ans de voyage en van de la France au Népal, on a sans hésiter investi dans 2 gourdes ÖKO car même si nous avions un système de filtration d'eau dans notre van, on s'est souvent retrouvés en bivouac ou en randos de plusieurs jours où la gourde ÕKO nous a bien manqué.
Être autonomes à l'autre bout du monde même en sacs à dos sans devoir acheter de l'eau en bouteilles : le top pour nous, comme pour la planète ! Avec nos 2 gourdes et notre réserve de filtres, nous sommes prêts à repartir en tour du monde !
La gourde filtrante OKO est pour nous une compagne de voyage inséparable: à la mer, à la montagne, en avion, à moto ou au travail, elle est toujours avec nous.
Nous n’avons plus besoin d’acheter des bouteilles en plastique, ni de chercher où les recycler.
Son filtre de 378 litres est pratiquement inépuisable et nous n’avons plus à nous soucier de la qualité de l’eau du robinet: il élimine les bactéries et les contaminants.
Nous l’utilisons même à la maison, à la place des lourds packs de bouteilles d’un litre et demi.
Bref, nous ne pouvons plus nous passer de la gourde filtrante OKO !
Merci pour cette invention fantastique !
