LifeStraw Go Series 22 oz Water Filter Bottle: Science-Backed Protection, Real-World Impact
The LifeStraw Go Series 22 oz water filter bottle is engineered for people who demand safe, great-tasting water—on the trail, at school, while traveling, or at your desk. This dual-stage bottle uses a membrane microfilter to remove 99.999999% of bacteria (including E. coli and Salmonella), 99.999% of parasites (Giardia, Cryptosporidium), and 99.999% of microplastics, as well as sand and silt. The activated carbon filter further reduces chlorine, odors, and organic chemicals for improved taste.
Built for real-world use, the membrane microfilter lasts up to 1,000 gallons (4,000 L)—the equivalent of 8,000 single-use bottles. The Go Series bottle is BPA-free, dishwasher safe (filters removed), ergonomic, leakproof, and available in multiple colors. Every purchase delivers a year of safe water to a child in need through LifeStraw’s Give Back program. The bottle is independently lab-tested to WHO, US EPA, and NSF standards, and LifeStraw is certified by B Corp and Climate Neutral.
Customers consistently praise the Go Series for its filtration performance, peace of mind, and ease of use. Some mention minor design tweaks could improve ergonomics and lid functionality, but the overwhelming feedback is positive—reflected in a 4.6/5 rating from over 670 reviews.
LifeStraw stands apart through rigorous, transparent testing, field-ready durability, and a built-in social impact model. For every bottle purchased, a child in need receives a year of safe water.
