The LifeStraw Go Series 22 oz is a BPA-free water filter bottle that lets you fill up from almost any fresh-water source — a tap in Mexico, a gas-station sink, or a backcountry stream — and drink safely through a two-stage filter built into the straw.
LifeStraw is a B Corp and Climate Neutral Certified brand, and the filter here is the same hollow-fiber membrane tech their original LifeStraw Personal Water Filter made famous, now packaged into an everyday bottle. For every purchase, the company funds a year of safe drinking water for a child in need.

What It Filters (and What It Doesn’t)
The membrane microfilter removes:
- Bacteria — 99.999999% (including E. coli and Salmonella)
- Parasites — 99.999% (Giardia and Cryptosporidium)
- Microplastics — 99.999%
- Sediment — sand, dirt, silt and cloudiness
The activated carbon filter is a second stage that removes chlorine, odors and organic chemical matter — the things that make water taste off even when it’s technically safe to drink.
One honest limitation: it does not remove viruses. For North America and most of Europe, backcountry water is a bacteria/parasite concern rather than a viral one, so this is rarely an issue. But if you’re travelling in regions where viruses are a risk, pair it with chemical treatment or UV purification.
What We Love vs. What Could Be Better
✅ What We Love
- Two-stage filtration improves both safety and taste
- Membrane lasts about 4,000 L (up to five years of daily use)
- Each purchase funds a year of clean water for a child
- B Corp and Climate Neutral Certified brand
- BPA-free and dishwasher-safe bottle (with filter removed)
❌ What Could Be Better
- Does not remove viruses
- Replacement carbon filter needed roughly every two months
- Sipping through the straw takes more effort than a plain bottle
- 22 oz capacity may feel small for all-day hikes
Color Options & Build
The bottle comes in a range of colors (Noir, Laguna, Icelandic, Kyoto, Cherry and more), with a translucent BPA-free body so you can see your water level at a glance.
Who Should Buy the LifeStraw Go
Great for: travelers who don’t trust the tap, hikers and campers who want a filter that’s always with them, and anyone who wants an everyday bottle that doubles as an emergency water filter.
Look elsewhere if: you need virus protection, you want a bigger or insulated bottle (LifeStraw sells stainless-steel versions for that), or you’d rather have a squeeze-style filter for group cooking.
Final Verdict
The LifeStraw Go Series 22 oz is one of the easiest ways to get proven, lab-tested water filtration into your daily carry. The two-stage filter genuinely improves both safety and taste, the membrane’s ~4,000 L lifespan keeps running costs low, and the give-back model is a nice bonus. The trade-offs — no virus removal and a recurring carbon-filter swap — are small for most users. If you want a dependable filter bottle for travel, hiking or emergency preparedness, it’s an easy recommendation.
