If I wanted to drink tap-water, I’d just drink out of my dog’s bowl. That irony taste just isn’t for me. iStraw is a lightweight polycarbonate straw with its own internal filtration system. Using micro-filtration, the straw removes much of the contamination from a glass of water.
The iStraw’s special internal membrane allows for water to be filtered without the use of more expensive methods. It’s great for personal use and you’ll never know when you’ll be stuck somewhere that needs the aid of a protozoa slaughtering straw. — Andrew Dobrow
