Filtration, Freshness and Pleasure

ÖKO Fresh isothermal filter flask

Imagine enjoying fresh, pure water after hours in the sun or after strenuous exercise. 


With the ÖKO Fresh insulated water bottle, this pleasure becomes a reality, whether you're in the office, at the gym, out in nature or just on the move. 


This water bottle maintains the temperature of your water for 5 to 7 hours, providing thirst-quenching, healthy hydration as each sip is purified. Its high-performance filter removes up to 99.99% of contaminants - bacteria, viruses, heavy metals, PFAS and even pesticide residues - guaranteeing ideal water wherever you go. 


Perfect for hot days and nature outings, this 600 ml water bottle slips easily into your bag, ready to turn every break into a pleasantly cool moment.

Revolutionary filtration technology

A direct legacy from NASA!

Thanks to an innovativeelectro-adsorption process, the ÖKO bottle transforms water from any source into pure drinking water. 


This filter, based on technologies developed by NASA, works like a contaminant magnet. It attracts and captures harmful elements in the water: viruses, bacteria, pesticides, heavy metals and even drug residues.


As the water passes through the filter, a field of positive charge surrounds each pore, attracting hazardous particles like a magnet. This advanced electro-adsorption filtration is preceded by 1.2-micron mechanical filtration and the use of activated carbon.


The result? Pure, safe, uncompromising water, wherever you are! Whether you're traveling, hiking or just going about your daily life, the ÖKO water bottle lets you hydrate with complete confidence.

The best flow rate on the market with the ÖKO water bottle

Isothermal filter flask

Unlike conventional filters, which use 0.1-micron pores and require suction, the ÖKO water bottle is distinguished by its 1.2-micron calibrated pores and patented electro-adsorption technology brought to us by NASA.


This unique technology delivers the best flow rate on the market (at equivalent filtration levels).

 

No need for forcing or vacuuming. Pressure filtration is intuitive, convenient and makes it easy to share filtered water, wherever you are.

Only one filter to change

With the ÖKO water bottle, you benefit from a single filter to be replaced every 400 liters. No expiration date. No forced replacement every few months.


Thanks to the ÖKO Counter mobile app, you can precisely monitor the amount of water filtered, so you know exactly when to replace the filter.


Independent tests carried out by manufacturer Ahlstrom and EUROFINS Euraceta show impressive results:

> 99.94% filtration of viruses, bacteria, cysts & parasites (e. coli and giardia lamblia)

95% filtration of lead, chlorine, PFAS, pesticides (chlorothalonil, etc.), herbicides and drug residues

NSF 401 for chemical compounds

Très belle invention

Top, la gourde tient bien 3h le chaud en ayant une eau en sortie bien chaude pour son lyophilisé ou infusion. Le revêtement intermédiaire avec les motifs paraît en papier, donc à voir comment ça tient dans le temps sur un plan esthétique.
