We love our Klean Kanteen, but we have to admit, sometimes it gets a bit heavy to carry around on the subway or when we're running errands. This water bottle from The Water Geeks would let you carry around an empty bottle, and refill from anywhere (almost) without worrying about the water's purity.
All of the bottles at The Water Geeks.com are BPA free.
The filtered bottles remove chlorine, heavy metals, and other contaminates, and they mean that you don't need to buy water bottles when you're on the go and contribute to the 10 billion plastic bottles that are sold each year.
The Water Geeks website is a great resource for learning more about water purification, conservation, and recycling. Click here to watch one of their videos on water bottle recycling.
