What does ÖKO mean in concrete terms?

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 becomes ultra-safe again

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 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🔍

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.

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) - BPA-, phthalate- and harmless agent-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 (if muddy: rinse the outside of the filter with water).
Bottle capacity
Available in 650 mL and 1 L versions
Filter life
Up to 379 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
