Why We Like It

LifeStraw Universal is the first bottle adapter kit with a 2-stage filter. Two different sized caps allow you to turn your favorite water bottle into a powerful water filter that removes 99.9999% of bacteria, 99.9% of protozoa and improves the taste of your water anywhere your adventures take you. With a lifespan of 1000 gallons, you can stay safely hydrated for years to come.


The Universal does not use chemicals and doesn’t require pumping or any energy input (like batteries). Pop it on the water bottle of your choice and you can safely drink from rivers, lakes, streams or other open, fresh water sources on your path.

And on top of all that, LifeStraw believes that doing good is good business. Through their Follow the Liters program, for every LifeStraw purchased, a school child around the world receives safe water for an entire school year. Cairn subscribers were a part of helping LifeStraw reach their goal of providing 1 million children with safe drinking water!
