I am constantly debating between plastic and glass water bottles. I really love the look of a glass water bottle, but the plastic is obviously more durable. Now the plastics come with a built-in filter, but I can filter my water before it goes into the glass. I've done my homework, but the debate still goes on, so you decide.
Bobble. It filters water as you drink in a myriad of colors.
Decor Craft Incorporated. Shaped like a traditional plastic bottle, this glass version has an air-tight lid and holds up to 20 ounces.
Nalgene. This commemorative bottle for The Surfrider Foundation and FilterforGood, doesn't include a filter, but is highly durable, doesn't retain odors and reminds us to reduce our personal waste.
Ikea. This sturdy glass bottle comes with an air-tight stopper.
