Water Filtration Bottle, OKO

KO Filtration Water Bottles
650 ml bottle.  Produces up to 100 gallons of drinking water 99.99% free of waterborne contaminants.

OKO Level-2 filters have been lab tested using NSF/ANSI testing standards. The most recent lab testing reflects 99.997%  reduction in Cryptosporidium presence and 99.9999% in Giardia Lamblia – the two most common bacteria found in water sources. We encourage the use of common sense and prudence when using water bottles to filter water in questionable sources and   when in doubt to boil water and/or use treatment pills in conjunction with the OKO Level-2 filter.

KO Filters & How They Work

KO offers three bottle filtration levels. All three produce superiorly efficient filtration with a powerful flow. Our patent-pending Upstream Valve returns any backwashed fluid into the unfiltered water area for re-filtration and to ensure that every sip is pure, fresh & clean.

KO Level-2 filtration, originally developed through a NASA grant for space stations, is now available for consumer use. 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 1micron each to virtually close the pore to any intruding agents. Using built-in silver ions, the material then kills bacteria upon contact.
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.

KOs 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 that allows the user to see water filtration in action as you drink. The bottles body is made of an ultra-light polypropylene material used popularly in food storage containers worldwide. Our semi-soft nozzle and washer create functional accents and the contoured shape makes the bottle easy to grip. The -ring carabiner is used to carry or hook the bottle onto a bag. These features, combined with the versatility provided by your filtration make KO the best water bottle in its category. KO bottles are dishwasher safe and easy to clean.
