The LifeStraw Go Series Replacement Membrane Microfilter is engineered for Go Series water bottles purchased in 2023 or later, offering advanced, two-stage protection for everyday hydration, travel, outdoor adventures, and emergency preparedness. This filter removes bacteria (including E.coli and Salmonella), parasites (Giardia and Cryptosporidium), microplastics, chlorine, organic chemical matter, silt, sand, and cloudiness—while improving taste. The membrane microfilter lasts up to 1,000 gallons (4,000 L), and the activated carbon filter lasts up to 26 gallons (100 L) or about 60 days of regular use.
LifeStraw’s independent lab testing meets or exceeds protocols from the World Health Organization, US EPA, NSF International, and the Water Quality Association, ensuring every filter performs when it matters most. As a B Corp and Climate Neutral Certified brand, LifeStraw embeds measurable social impact into every purchase: for each product sold, a child in need receives a year of safe drinking water.
Customers praise the filter’s ease of use, water quality, and peace of mind—whether for daily use, travel, or emergencies. The filter is easy to install, and replacements are widely available. LifeStraw’s commitment to transparency, science-backed claims, and real-world readiness sets it apart in water filtration.
