The LifeStraw turns practically any water source into drinking water, so it’s no wonder it’s popular among hikers and outdoor enthusiasts. And now the LifeStraw Universal allows you to turn your favorite water bottle into a source of pure, filtered bottled water. So whether you’re drinking from a sketchy water fountain in a South Pacific airport or refilling your bottle from a waterfall during a day hike, you’ll be set.

LifeStraw’s two-stage filter removes at least 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan parasites. It was originally engineered to give those in developing countries access to safe drinking water. LifeStraws are also huge assets for those impacted by natural disasters, and they’re rapidly becoming part of essential relief packages worldwide. A few years after LifeStraw’s advent, people started realizing that LifeStraw technology can revolutionize everyday first-world experiences as well.

Every LifeStraw Universal you purchase supplies a child in a developing country with clean water for a full year, so it’s the kind of purchase you can feel great about. Plus, your LifeStraw Universal will come with two different lid options to fit a wide variety of water bottles, and it’s tough enough to withstand practically anything your adventures throw at it.
