LifeStraw Personal Water Filter Straw

No pumping, no moving parts, no waiting for gravity to work: just insert the end in a water source and suck. The updated LifeStraw has a higher flow rate than the previous version, and now has a threaded end that attaches to 28mm mouth bottles (like a soda bottle), allowing you to store dirty water for drinking later. It's small size is perfect for personal use or for your emergency kit. When you’re done drinking, simply blow residual water out and replace the end-caps.
