OKO Filters for Water Bottle (Level 2)

OKO takes the concept of the eco-friendly water container one step further with NASA derived filtration technology, packaged in a smartly designed bottle with a super-light, high-tech blend of materials - ensuring that you're always drinking safe, pure, potable water in style. It's the ideal choice for everyday use, travelers, adventurers, hikers, yogis, runners, and anyone who needs convenient access to clean, clear, crisp water. And with 3 sizes, 6 designer colors, and 3 levels of filters, it's easy to have the ÖKO bottle that's right for you. OKO bottles are made from a customized, proprietary blend of food grade plastics that has passed stringent SGS testing for FDA food contact safety. The bottle cap is made of Tritan, a BPA-free clear hard plastic that allows you to see the water filter working as you drink. The bottle design makes it easy to carry, or use the O-ring carabiner to carry or hook the bottle onto a bag. And it's dishwasher safe and easy to clean! OKO's patent-pending filters use a positively charged electro-adsorption process to attract harmful agents and then kill bacteria on the filter surface using silver ions. The one-way Upstream Valve" allows for a steady, fast and efficient filtration with a powerful flow, filtering liquid every time it passes through the bottle's mouth and preventing the musty smell that most bottles acquire over time as liquid is inadvertently backwashed during the course of use. This combination ensures pure, fresh and clean-tasting water with every sip.
