Clean water is only a fingertip away with the OKO Filtration Water Bottle. Water is essential for every activity and to sustain life itself. OKO has created a relatively complex filter system in one simple easy-to-use well designed water bottle. This high-tech Nasa derived system is the perfect answer for those worldly travellers and urban dwellers sick of the taste of nasty chemicals in their drinking water. I’m not sure how many times I’ve traveled where the water quality was questionable, and you’d have to buy expensive pre-packaged water. OKO uses a variety of carbon based filters offering 3 different levels that are good for a variety of contaminated water sources. The bottles are manufactured using BPA free plastic, and have passed stringent SGS testing. Available in 3 sizes and 6 colors, all that is left for you to do is find the right one. Get em here.
