LifeStraw Personal Water Filter (4-Pack) (Blue) Personal Water Filter

The LifeStraw Personal Water Filter (4-Pack) in Blue is a practical and reliable hydration solution for outdoor adventures, emergency preparedness, and travel . This pack includes four of the iconic, ultralight personal water filter straws, each weighing less than 2 ounces (46 grams), making them easy to pack in any bag or pocket .

At the core of each filter is a 0.2-micron hollow fiber membrane that effectively removes 99.999999% of waterborne bacteria (including E. coli and Salmonella) and 99.999% of parasites (like Giardia and Cryptosporidium) . It also filters out microplastics, silt, sand, and cloudiness, improving water clarity . The BPA-free straw can be used to drink directly from lakes, rivers, and streams .

Each filter in the pack has a long lifespan, capable of filtering up to 1,000 gallons (4,000 liters) of water, which is enough to provide one person with drinking water for over five years . The filters have an unlimited shelf life when stored unused, making them an ideal, worry-free component for emergency kits . Furthermore, every purchase supports LifeStraw's Give Back program, providing a year of safe water to a child in need .
