Bobble 550ml Drinking Water Bottle Filter Reusable Sport Outdoors Fitness Drinks 
Bobble is a stylish, reusable bottle that filters water as you drink, using an ingenious replaceable carbon filter. when water passes through the filter, the carbon removes chlorine and organic contaminants. bobble is intended for municipal tap water making water better, with every sip.  Bobble is a beautiful, sleek 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, you’ve removed thousands of bottles from the environment, simply by filtering the water from your tap. bobble is free of BPA, Phthalates and PVC. and it is guilt-free as well. enjoy!  Filter facts.   Bobble has an activated carbon filter which has a slight electro-positive charge, making it attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules. 
Carbon filters require very little maintenance, and are perhaps the most powerful chemical absorbents known to man. bobble's carbon-based filter removes organic contaminants from regular municipal tap water and meets or exceeds NSF International Standard 42 for chlorine, taste and odour reduction. 
For best results we recommend changing your filter after 2 months or 40 gallons/150 litres. Filter for use with bobble only.
