ÖKO Fresh isothermal filter flask (filter included)

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 confidence.

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.

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
