What is ÖKO?
1
From NASA
NASA created this technology in 2002 to filter the water on the ISS.
This filter is capable of eliminating pollutants* potentially present in tap** and rural water, such as microplastics, bacteria, viruses, PFAS, heavy metals, chlorine, pesticides, fluoride and drug residues etc etc.
2
Tap water becomes ultra-safe again
3
Non-drinkable water becomes drinkable again*.
Whether you're hiking, trekking, traveling, taking the train or abroad, where the water is unfit for consumption, with ÖKO you can drink without fear, because the filter eliminates the pathogens most commonly found in freshwater sources around the world*, responsible for unpleasant gastric discomforts.
(*) Official list of the 120 countries concerned on our dedicated page.
Always select and judge the water you consume with care: each water source has its own composition and may require additional treatment.

Tested & validated by
Lille Pasteur Institute
One of the few laboratories in France accredited and equipped to handle pathogenic viral and bacterial strains.
The Institut Pasteur, in 2025, confirmed the results of past laboratory tests:
ÖKO effectively filters viruses* and bacteria* from water (99.99% and 99.999%)

🔍3 steps to understanding filtration🔍
01
Filter composition
The filter membrane consists of a natural mineral fiber(AIOHH pseudoboehmite), antibacterial ions and a microscopic sprinkling of activated carbon.
It is 8 mm thick and has over 400 pores.
02
Mechanical filtration
Its pores are calibrated to 1.25 microns, mechanically blocking all particles equal to or larger than this size, such as sediments and impurities.
03
Submicron filtration
On contact with water, the natural mineral fiber emits a positive charge field that surrounds the hollow volume of the pores. The water is thus freed of submicronic contaminants, attracted like a magnet to the membrane's retention surface. This is electro-adsorption.

For our children and our planet
The next generation
Let's teach them the right gestures from an early age.
Thanks to ÖKO!
For our planet
Less plastic pollution. For future generations.
Thanks to ÖKO!
Muddy water becomes perfectly clear and drinkable again
Why does ÖKO use plastic?
- Guaranteed free from BPA, phthalates, microplastics and other toxic substances.
- Compressible and lightweight : thanks to this flexible material, you can easily squeeze and propel water through the filter.
- Tough and durable: designed to last for many years, withstanding both high temperatures and daily use.
- Tasteless and odourless: preserves the natural, pure taste of your water.
- At the end of its life, your water bottle body can be 100% recycled.

Technical data
Technology
ÖKO's ultra-filtering flask combines unique alumina nanofiber technology, derived from the mineral pseudoboehmite, with mechanical filtration with medium-sized pores of 1.25 microns.
Flow
Up to 10x higher than equivalent filtration systems (2 L / min)
Material
Polypropylene (PP5) and Tritan (cap) - BPA-, phthalate- and microplastic-free.
Maintenance
The gourd, pipette and cap (without filter) can be easily washed at room temperature with soap and/or water.
NEVER clean the filter or put it in contact with anything other than water (if you have to filter muddy water: rinse the outside of the filter with water).
Bottle capacity
Available in 650 mL and 1 L versions
Filter life
Up to 378 L (with clear, low-sediment water). The more sediment in the water, the shorter the filter life.
Weight
147 g (650 mL bottle) / 172 g (1 L bottle)
Dimensions
H 23.3 cm (650 mL) / H 26.5 cm (1 L)
Diameters
Ø 71 mm (650 mL) / Ø 85 mm (1 L)
Included in the water bottle
Carabiner, nozzle cap and ÖKO filter
What do you think of our ÖKO filtering water bottle?
Je teste depuis 1 mois la gourde filtrante ÖKO 650 ml. Je suis plutôt satisfaite. Une prise en main rapide sur ce produit. Les explications concernant le filtre, le le protège-pipette, l'entretien sont claires. Le format 650 ml me convient parfaitement. Le système de pression pour propulsion mécanique (et non pas aspiration) est rapidement pris en main. Veillez à bien revisser la gourde sur le filtre afin d'éviter les fuites. J'apprécie également l'astuce du mousqueton pour caler le protège-pipette, bien pratique. En bref, bon produit qui permet de pouvoir s'hydrater partout sans soucis.
J’ai découvert cette gourde en voyage je l’ai donc acheter et c’est super efficace je l’ai même fait découvrir à mes parents ils adorent!
Hello !
La gourde est géniale et correspond parfaitement à mes besoins au quotidien. Seul petit bémol : dans un cadre plus aventureux (dernièrement, un trek d'une quinzaine de jour dans mon cas), même en faisant attention à la gourde, sa surface s'abime assez rapidement selon moi (même si cela reste léger, je pense au long terme au vu de l'achat d'une gourde relativement couteuse).
J'espère que mon avis sera utile au plus grand nombre ! :)
Merci OKO
je revis , enfin je bois sereinement sans me soucié de ce qu'il y a dedans
Je me sers de l'Oko 650 ml comme pompe filtrante à mon travail, en rando etc....
Je préfiltre souvent avec mon tour de cou afin d'optimiser la longévité de mon filtre.
Je remplis avec mon camel bag et ma gourde métal simple paroi au goulot large qui me permet d'apprécier alors la limpidité du breuvage!
