FDA food contact safety. The bottle cap is made of Tritan, a BPA-free clear hard plastic renowned for its durability and

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 O-ring carabineer is used to carry or hook
the bottle onto a bag. These features, combined with the versatility provided by your filtration make OKO the best water
bottle in its category. OKO bottles are dishwasher safe and easy to clean.
OKO Level-2 Filter
------------------
OKO Level-2 filtration, originally developed through a NASA grant for space stations, is now available for consumer
use. 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. Using built-in silver ions, the
material then kills bacteria upon contact. OKO level-2 filter lab tests reflect removal of 99.94% of e-coli, 99.997% of
cryptosporidium and 99.9999% of giardia lamblia, the most commonly found bacteria in water sources.
Up to 100 Gallons of Refills
----------------------------
The lifespan of your filter greatly depends on the quality of the water you filter through it. The more contaminated
the water, the shorter the life of the filter. We suggest you change it every 50 gallons for best tasting water but it
should be fine for up to 100 gallons. 550ml bottle: Based on 100 gallons of mostly tap water, you will get 750 refills.
650ml bottle: Based on 100 gallons of mostly tap water, you will get 580 refills. 1000ml bottle: Based on 100 gallons of
mostly tap water, you will get 375 refills.
