Each Bottle is A Water Purifier.

321 — pronounced “three to one” — is a reusable water bottle, or more exactly a portable water purifier designed to provide clean water to travelers. The concept behind the simple name is quite impressive: three liters of water is required to manufacture merely one liter of bottled water, but you could save more water using the 321 Water. Besides, the product also helps to reduce the need of plastic bottles.
Designed by Gretha Oost, Paul Charlwood and Andrew Howley, the innovative water purification system is easy to use, all you have to do is to fill the bottle with tap water through a drip system and slot in the filter.
One filter can last 100 uses (about 50 liters) and it could be purchased separately.
Selling Price: $44.6 (Limited Edition Bottle, with one filter included)

I have to say that water bobbles cost A LOT less and do the same job. I definitely am getting a water bobble, which I think will reach more people, as it is more affordable at $10 a pop.
