"You probably know all about the massive impact bottled water has on the environment and you want to do something about it. So do we. That’s why we’ve invented 321 Water.
This beautifully designed, re-usable water bottle has a unique plunger mechanism with a built-in filter, so you can fill it from any tap to produce fresh, filtered water.
It’s the most stylish way to stay healthy and hydrated whilst reducing the use of fossil fuels, carbon emissions and waste associated with drinking bottled water."
One more shot after the jump. More info on the 321 Water website.
