“Believe it or not, few water bottles are actually recycled. As it turns out, only 38% of plastic water bottles are actually recycled, while the other 62% ends up in landfills across the U.S. And for every 1 liter of bottled water, 3 liters of water are used in the cleaning and manufacturing process. Lastly, the bottling process emits millions of tons of carbon dioxide into the air every year. When you use an at-home water filter, you help reduce the number of bottles that end up in landfills, as well as reduce the amount of water wasted during bottled water production.”
