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 protecting against bacteria (like E.coli), parasites (like Giardia and Cryptosporidium), microplastics, and silt, sand, and cloudiness. 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, and is rigorously tested to meet drinking water 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.
