Go Series 650ml Water Filter Bottle

The LifeStraw Go Series is a 650ml dual-filter water bottle that handles two distinct jobs at once. The 0.2 micron membrane microfilter removes bacteria, parasites, and microplastics from untreated natural water sources — the same core protection as the LifeStraw Sip straw. The added activated carbon filter reduces chlorine, odours, and organic chemical matter from treated tap water, making the Go Series practical for both backcountry use and daily urban carry. One bottle, 4,000L of membrane life, five years of daily use from a single filter replacement. Dual filtration: membrane and activated carbon — the membrane microfilter (0.2 micron, 4,000L life) provides the core water safety protection. The activated carbon filter (100L life, approximately two months of daily use) sits in-line and reduces chlorine taste, organic chemical matter, and odours — bringing tap water to a cleaner, better-tasting standard and removing residual treatment chemicals from treated municipal supplies. Membrane microfilter — what it removes — 99.999999% (8-log) of bacteria including E. coli and Salmonella; 99.999% (5-log) of parasites including Giardia and Cryptosporidium; 99.999% of microplastics, silt, sand, and cloudiness. Meets US EPA and NSF P231 standards for bacteria and parasite removal. 4,000L membrane filter life — approximately five years of daily use from a single membrane filter and the equivalent of 8,000 single-use plastic water bottles replaced. Both the membrane and carbon filters are replaceable, so the bottle has an indefinite service life. 650ml capacity — a practical day-use volume for hiking, travel, commuting, and everyday carry. Fills from any tap, stream, lake, or questionable municipal source and filters as you drink. Replaceable filters and parts — both the membrane microfilter and the carbon filter are available as replacement parts. The bottle body, mouthpiece, and cap are also replaceable, making the Go Series a long-term investment rather than a consumable. BPA-free, dishwasher safe — all materials are BPA-free. The bottle is dishwasher safe once the filter is removed. B Corp and Climate Neutral Certified — independently verified social and environmental performance across LifeStraw's operations. Safe water giveback — one year of safe drinking water for a child in a low-access community per product purchased, independently verified. Important: The Go Series membrane filter does not remove viruses. For travel in regions where viral waterborne illness is a risk, additional treatment is required.
