Advanced Filtration Bottles
When You’re Serious About Water Filtration
ÖKO combines water filtration technology originally designed for use in NASA ISS (International Space Station) with an elegant bottle design made of 100% FDA compliant materials. 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, the ÖKO level-2 filter (included with every bottle), has been lab tested to remove 99.9999% of giardia lamblia & 99.997% on 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).
For a listing of the appropriate filter please refer to the ÖKO ON THE GO Chart.
ÖKO’s patented water bottles are made from a customized blend of plastics that have passed stringent SGS testing for FDA food contact safety. 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.
Our 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.
ÖKO Filters & How They Work:
All Bottles come Equipped With our ÖKO Level-2 advanced Filter.
ÖKO Level-1 filter is carbon based and it is designed to effectively reduce present chlorine, taste and odor while providing crisp and clean tap water. This filter emits the fastest water flow with effective filtration. This filter is sold separately.
ÖKO Level-2 filtration, was originally developed for NASA and used in the ISS (International Space Station). We convert the material for consumer use in our bottles. Simply put, it is the state of-the-art in water filtration technology.
In addition to a 2 micron pore size, the material utilizes a positively charged electro-adsorption (attraction and retention) process to draw and trap harmful agents much smaller than its pore size. Charge fields, activated upon water contact extend 1 micron each to virtually close the pore to any intruding agents. ÖKO level-2 filter lab tests reflect removal of 99.994% of e-coli, 99.9999% of cryptosporidium and giardia lamblia, the most commonly found bacteria and microorganisms in lakes, streams and international water sources. A stack of over 400 such pores in the 0.8mm thickness of the filter create a “tortuous path” which a harmful agent would have to travel through in order to make it across the filter membrane.
