ÖKO, c’est quoi ?

Une gourde filtrante efficace : pour les petits et les grands !

Facile d'utilisation : il suffit de presser pour filtrer instantanément !

Contenant en plastique PP5 : mou (pour pouvoir presser), sans BPA, sans phtalates ni microplastiques.

=> Il dure des années, il n'y a que le filtre à changer tous les 378 L (soit 1 an si 1L / jour ou 6 mois si 2L / jour) !

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.

(*) Those tested in laboratories

(**) Tap water is potable according to standards, and ÖKO makes it much healthier by eliminating a broad spectrum of pollutants that are likely, by 2025, to exceed standards and/or that are not filtered by treatment plants (which are not equipped).

Tap water becomes ultra-safe again

From "potable" to ultra-sanitary: no more unpleasant odors, no more chemical tastes, and a softer, lighter texture. Thanks to ÖKO, tap water is once again pleasant to drink and enjoy every day.

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 worldwide*, responsible for unpleasant gastric discomforts.

🔍3 steps to understanding filtration🔍

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.

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.

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.

Laboratory tests

Here is the range of contaminants filtered by ÖKO:

Virus

99.98% filtration

Those tested

Bacteria

99.9999% filtration

Those tested

Cysts, parasites

99.9993% filtration

Those tested

E. Coli

99.94% filtration

Endotoxins

83% filtration

Those tested

Chlorine

95% filtration

Drug residues

And chemical compounds (BPA...)

95% filtration

Those tested

Fluorine

The EU has set a threshold of 1.5 mg/L, but children should not exceed 1 mg/d ⚠️

No more visible traces

PFAS

Eternal pollutants that remain in our bodies for life

No more visible traces

Those tested

Heavy metals

Lead, Cadmium, Iron, Manganese, Copper, Nickel

Between 95% and 99

Those tested

Plastic

Microplastics are present in tap and bottled water

No more visible traces

Pesticides & herbicides

Groundwater contaminated by agricultural use

No more visible traces

Those tested

DISCLAIMER: Laboratory tests attest to the effectiveness of ÖKO filtration technology, developed by NASA (2002), against a broad spectrum of contaminants potentially present in tap or bottled water.

However, water can have an infinite number of different compositions. No filter in the world can be tested on all these variants.

At ÖKO EUROPE, we believe in transparency. Although our filter is efficient, its effectiveness will always depend on the quality of the filtered water.

Tip : use your water bottle with reasonably safe water sources whenever possible.

Why does ÖKO use plastic?

At first glance, you may wonder why we use plastic for our ÖKO water bottles?

ÖKO water bottles are made of special polypropylene (PP5), a food-grade material identical to that used for food storage containers and with ideal qualities:

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.

Why not glass or stainless steel?

Glass breaks and stainless steel is simply heavy!

To date, no alternative material offers the flexibility, lightness and practicality of polypropylene for a quality filter flask.

Only the filter needs to be changed regularly, reducing your ecological impact.

Fini les lourds packs d'eau....

Ah oui !, c'est vrai qu'elle est bien bonne l'eau de ma gourde Ôko qui ne me quitte plus ! Très pratique, et enfin une eau agréable à boire, et saine, le top ! Merci Ôko de l'avoir créée ! Il en faudrait à tout le monde ! Et super site en plus !

Très bon article avec un filtre vraiment efficace. Fini l'achat des bouteilles d'eau

Agréablement surprise par cette gourde de 650ml. Pratique, facile à utiliser, s'emporte partout.
Je l'utilise tous les jours pour boire l'eau du robinet. Le filtre est très efficace. Plus de goût de chlore, plus d'odeur.
L'eau à un très bon goût et reste fraîche quand elle passe dans le filtre. Je trouve l'eau filtrée de cette gourde bien meilleure que beaucoup d'eau de source ou minérale.
Je m'en sers également pour remplir mes bouteilles Sodastream.
Très bon produit que je recommande à tous ceux qui veulent boire une eau propre et agréable.

Cette gourde est magique

Je prends soin de ma santé grâce au filtre de cette gourde et je suis rassurée de ne pas boire des restes de médicaments ou de métaux lourds présents dans l’eau du robinet. De plus elle est très facile d’utilisation. Je vais en commander une pour mon fils également. Merci Oko!
