LifeStraw, the original ultralight backpacking and travel-friendly “straw” water filter, makes contaminated water safe to drink and helps to prevent most waterborne diseases by removing bacteria (like E.coli), parasites (like Giardia and Cryptosporidium) and microplastics. Drink directly from lakes, rivers and streams or fill a container to use your LifeStraw on the go. The LifeStraw can provide up to 5 years of safe drinking water with proper use and maintenance. The LifeStraw is rigorously tested to meet protocols established by the US Environmental Protection Agency (EPA) and NSF International/ANSI. Your purchase has impact. For every LifeStraw product purchased, a school child in need receives safe water for an entire school year.
