America has the cleanest public water supply in the history of the world. And yet what do we fill our garbage dumps with? Tons of plastic water bottles. While recycling programs have reduced the excess, hundreds of thousands of tons of carbon dioxide are released into the atmosphere by the creation of new bottles.

Trying to reduce energy demand and plastic waste simultaneously, Back to the Tap has created a water bottle that filters water as you drink, elevating even the most questionable tap water to the level of Evian. While the filter needs to be replaced every three months, the recyclable bottle will last as long as you keep filling it, and since it’s made of super-safe LPDE plastic, it won’t leech phthalates like some other polymers have been known to do.

Not sure how they ran the math on this, but the makers estimate it will save some 1,000 water bottles per person per month, reducing plastic waste in our oceans and landfills, and decreasing carbon emissions. Plus, because plastic is an oil product, this bottle will help reduce the oil price as well as reliance on foreign oil sources.
