Bobble Water Bottles are perfect for those on the go – whether you are on the go by foot, car, train, plane or bicycle! As well as looking great they are incredibly clever and eco friendly because they filter water as you drink it. They have a removable carbon filter which has a slight electro positive charge. This charge attracts chemicals and impurities in the water as it passes through the filter, making it cleaner and tastier! Carbon filters require very little maintenance and are perhaps the most powerful chemical absorbant known to man. This Bobble Water Bottle features a soft touch integrated cap and an easy to carry handle. Bobble Water Bottles are an alternative to single-serve plastic water bottles, which harm the earth (and your wallet!). Every filter equates to 300 single-serve bottles. After a year, youve removed thousands of bottles from the environment, simply by filtering the water from your tap. Bobble is free of BPA, Phthalates and PVC.
