What does ÖKO mean in concrete terms?

An ultra-filtering water bottle for young and old alike
NASA Spinoff filtration

1

From NASA

La NASA a créé cette technologie en 2002 pour filtrer les eaux de l’ISS.

This filter is capable of eliminating molecules potentially present in tap and rural water, such as microplastics, bacteria, viruses, PFAS, heavy metals, chlorine, pesticides, fluoride and drug residues etc. etc.


Tap water filtration system

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.

L’eau non-potable redevient potable*

En randonnée, en trek, en voyage, en train, à l’étranger où l’eau est impropre à la consommation, avec ÖKO, vous pouvez boire sans craintes, car le filtre élimine les agents pathogènes les plus communément présents dans les sources d’eau douce du monde entier*, responsables des désagréments gastriques, peu agréables.

Sélectionnez et jugez toujours avec soin l’eau que vous consommez : chaque source d’eau possède sa propre composition et peut exiger des traitements complémentaires.

Only one filter to change

Only 1 filter to change

BPA-, phthalate- and microplastic-free, the bottle body and cap can be used for many years. One filter = 379 L of filtered water, with no expiration date and no obligation to change every month (like filter jugs).

3 steps to filtration🔍

Öko filter under the microscope

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.

1.4 micron mechanical filtration

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.

Submicron nanofiltration

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

DISCLAIMER: Laboratory tests attest to the effectiveness of ÖKO filtration technology, developed by NASA (2002), against a broad spectrum of contaminants found in tap and 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.

Filtre Nouvelle Génération

J’apprécie beaucoup la Société Oko, qui sont à votre écoute , service rapide, et un très Bon Service Après Vente.
Comme je vous l'ai dit dans mon précédent courrier, je trouve la bague de comptage est ridicule car la gourde de 1 litre on la remplis 400 fois et que la bague de comptage est de jusqu'à 12. quand j'ai acheter le filtre avec la bague de comptage, je pansais que c'elle si serais graduer jusqu'à 50 ou 100 avec au dessus une autre bague graduer de 1 à 8 pour le graduée ou de 1 à 4 pour le gradué à 100 50 comme ça la grande bague arriver a 50 ou 100 la seconde montais d'un chiffre jusqu'à arrivé a la fin de vie du filtre. je pense que cela aurais value l'augmentation du filtre des 5€. Pour le moment je vais acheter un filtre donc la graduation mes inutile. Pour le moment j'utilise un élastique pour noter les quantités de remplissage de la gourde sans utiliser l'application.
Bien sur je compte faire un retour sur ma chaine youtube
