LifeStraw Replacement Membrane Microfilter for Go Series 2.0 Stainless Steel Bottles

The LifeStraw Replacement Membrane Microfilter keeps your Go Series Bottle functioning at its best, delivering clean, safe water wherever you go.

Designed for 2023 and later Go models (not compatible with earlier models that feature the flip-up mouthpiece and carabiner attachment), this powerful microfilter protects against bacteria (including E.coli, Salmonella), parasites (including Giardia and Cryptosporidium), microplastics, chlorine, organic chemical matter, silt, sand and cloudiness, removing contaminants that affect both safety and taste.

Each filter lasts up to 4,000 litres, and automatically stops flowing when it’s time to replace. It’s the core of LifeStraw’s trusted two-stage filtration system, keeping you hydrated and protected on trail runs, hikes, or international travels.

Your purchase of any LifeStraw product provides a year of safe water to a child in need.
