If you're looking for an eco-friendly water filtration system (that's cool looking to boot), take a look at the Charcoal Water Pitcher.
The clear water pitcher is filled with charcoal in the center, which is said to both filter the water and add nutrients. The design is pretty and modern and the charcoal doesn't have to be replaced for 6 months (which is good for forgetful folks like me).
Implications - Due to increased media coverage, consumers are very aware of the manufacturing practices that their products and foods undergo. For this reason, they demand eco-friendly products that will benefit the planet as well as their health. Companies that desire to cater to green and active demographics can keep this in mind when designing their products.
