OKO 650ml Filter Bottle

ÖKO combines water filtration technology originally designed for use in NASA ISS (International Space Station) with an elegant bottle design.

The combination yields a unique filtration bottle which is lightweight, versatile and can deliver the highest quality water from innumerable water sources in over 140 countries.

With a filter capacity of 100 gallons (378 litres) , the ÖKO level-2 filter (included with every bottle), has been lab tested to remove 99.9999% of giardia lamblia & cryptosporidium, two of the most common contaminants found in open water sources worldwide.

ÖKO bottles may also be used with other filtration levels (sold separately).


  • The bottle cap is made of Tritan®, a BPA-free clear hard plastic renowned for its durability and clarity. It also allows the user to see water filtration in action
  • The bottle’s body is made of an ultra-light polypropylene material commonly used in food storage containers. Due to the material’s high temperature resistance, it does not leach chemicals or smell when exposed to warmer temperatures.
  • Semi-soft nozzle and washer create functional accents and the contoured shape makes the bottle easy to grip. The Ö-ring carabiner is used to carry or hook the bottle onto a bag.
