a water filter helps you minimize the harmful environmental consequences of buying bottled water. Incredibly, if a mere ten percent of North America's bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:
133,000 trucks driving an average of 500 miles--saving nearly 12 million gallons of diesel fuel
Over 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually
213 million pounds of PET--equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%
multiply that by 10 to see what getting rid of bottled water would do. most bottled water is not as healthy as filtered tap water.
