The '321 Water Bottle' by Gretha Oost, Paul Charlwood and Andrew Howley blends the portability of bottled water with the potability of a filtration system. The '321 Water Bottle' acts like a French press coffee maker--just add water, insert the filter and push it down. The BPA-free bottle is meant to make filtered water accessible anywhere.
While the '321 Water Bottle' is great for people on the go, for home use, boiling water is still my pick for places without potable water.
