iStraw filters as you drink

If you’re one who is uncomfortable about the idea of drinking water straight from the tap, purchasing the iStraw with you certainly sounds like an excellent idea. After all, this lightweight polycarbonate straw comes with its own internal filtration system and uses micro-filtration, removing contaminants from a glass of water. An internal membrane filters water without following more expensive methods, although I must say you would look rather weird drinking through the straw everywhere you go. It filters up to 500 liters of water before you need to purchase a replacement. The iStraw retails for £19.99.
