Filtering Water Bottle Description

The ÖKO water bottle combines technology originally designed for use in NASA’s International Space Station, with an elegant bottle design made of 100% FDA compliant materials.

The combination of filter materials yields a unique filtration bottle which is lightweight and versatile.  It can deliver the great quality water from various 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 & cryptosporidium, two of the most common contaminants found in open water sources worldwide.

The OKO Water Bottle

ÖKO’s patented water bottles are made from a customized blend of plastics that have passed stringent SGS independent testing and verification 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 itself is made of an ultra-light polypropylene material commonly used in food storage containers. The material has a high temperature resistance. It does not leach chemicals or smell when exposed to warmer temperatures.

The semi-soft nozzle and washer are not only functional, they add an attractive design element.  The contoured shape makes the bottle easy to grip and comfortable to hold. The Ö-ring carabiner (now heavier duty) is used to carry the filtering water bottle, or hook it onto a bag or something else.

All Bottles come with an ÖKO Level-2 Advanced Filter.   Provides advanced filtration for day-to-day use, for travel or the outdoors.

ÖKO Level-2 filtration was originally developed for NASA and used in the International Space Station. This is state of-the-art water filtration technology in an affordable filtering water bottle.

In addition to a 2 micron pore size, the water filter material uses a positively-charged electro-adsorption (attraction and retention).  This important process draws and traps 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 0.8 mm thickness of the filter create a “tortuous path” which a harmful agent would have to travel within the filter.
