Quick answer
All three are good — for different scenarios. GoPure wins on value for daily use and the European Camino (€60, 800 ml, 1,500 L lifespan). LifeStraw Go 2.0 is the entry-level option from a known brand (€40, no activated carbon). Katadyn BeFreeis the ultralight for trail runners (60 g but it's a soft flask, not a bottle). Details below.
If you're comparing these 3 filter bottles, you've already done 90% of the work: you ruled out the cheap no-brand Amazon options (they break in 6 months) and the Grayl GeoPress (twice the price and overkill for Europe). Now you have to pick between the 3 real brands on the European market.
This is an honest comparison. We sell GoPure — we won't hide it. But we're also going to tell you when LifeStraw or Katadyn are a better choice for your specific case.

GoPure — the pick for European daily use
Designed in Galicia for the European market. Combines a 0.2 μm hollow-fibre membrane + activated carbon prefilter. The carbon is the key: it removes chlorine taste, iron and sediments the other two let through.
Strengths:
- 800 ml — the largest capacity of the three
- 1,500 L filter life (50% more than the competition)
- Removes chlorine — critical for tap water and albergues
- Paracord strap + non-slip silicone base
- Dual opening (fast sip or wide refill)
- ABS + PP, BPA-free
Weak spots:
- Most expensive of the three (€60)
- Weighs the same as LifeStraw (220 g) — not ultralight
- New brand vs established ones (fewer accumulated reviews)
When to pick it:daily use at home + European Camino + vanlife. Any scenario where you'll drink from taps (where chlorine bothers you) and rural untested fountains. The activated carbon makes it the only one with real, natural water taste.
LifeStraw Go 2.0 — the entry-level pick
LifeStraw is the most globally known brand. The Go 2.0 is their bottle model (on top of the iconic "straw" that lets you drink directly from the river). 0.2 μm hollow-fibre membrane, no activated carbon prefilter.
Strengths:
- Lower price (€40)
- Established brand — recognizable internationally
- Every purchase funds drinkable water in developing countries (real social mission)
- Consistent accumulated reviews
Weak spots:
- No activated carbon— water tastes exactly like at the fountain (good if it's good, bad if it has chlorine or iron)
- Only 650 ml capacity
- 1,000 L filter life (more filter changes over product life)
- Basic design — no premium extras
When to pick it:a first cheap filter to try, or if you're going to high-mountain sources or springs where taste is already good. Also if LifeStraw's social mission resonates with you.
Katadyn BeFree — the ultralight for trail
Katadyn is the Swiss brand for extreme outdoor filtration. The BeFree is their lightest model: a soft flask with a screw-in filter. Not a rigid bottle — you drink by squeezing it.
Strengths:
- 60 g total — lightest on the market
- 0.1 μm filter — finest of the three (catches more bacteria)
- Packs down to fist-size in your bag
- Swiss brand — top reliability
- Very popular among ultra-runners and trail users
Weak spots:
- It's a soft flask, not a bottle— no real drop resistance and doesn't serve as a permanent container
- 600 ml capacity, but hard to keep upright and full
- No activated carbon — same chlorine issue as LifeStraw
- The flask degrades in sun and use — 6-12 months
When to pick it:trail running, ultra-trail, expeditions where every gram counts. If your priority is extreme weight and you don't mind squeezing a flask.
Recommendation by profile
Camino pilgrim (Francés, Portugués, Norte)
GoPure.You'll drink from village fountains with variable chlorine, from taps in centuries-old albergues with sediment, and from mountain sources with particulates. Activated carbon makes the real difference. The €20 extra over LifeStraw pays back on day one of the Meseta.
Daily use at home + office
GoPure. This is where the activated carbon shows most — every European tap has chlorine. The bottle looks good on the desk and lasts years. LifeStraw without carbon leaves you drinking pool-tasting water.
Trail running / ultra-trail
Katadyn BeFree. The 60 g is unbeatable. The flask fits in a trail vest without taking volume. For 6-12 months of intensive use it performs perfectly.
First filter to try without spending much
LifeStraw Go 2.0.At €40 it's the entry gate. If you get hooked on the filter concept and use it a lot, in a year you upgrade to GoPure for the activated carbon.
Travel to India, Nepal, rural Africa
None of the three.You need an antivirus purifier like Grayl GeoPress (€120) or SteriPen UV. These 3 don't filter viruses, and in those areas viruses are a real risk.
The activated carbon detail (why it matters)
The main difference between GoPure and the other two is the activated carbon prefilter. This component:
- Absorbs chlorine and chloramines from municipal water — water tastes like water, not pool
- Removes volatile organic compounds — pesticides, industrial trace chemicals
- Neutralises iron and sulphur tastes — typical of well water and old pipes
- Radically improves taste— the difference between "filtered" and "good"
LifeStraw and Katadyn filter bacteria as well as GoPure, but they don't change taste. If water comes in with chlorine, it goes out with chlorine. That's the #1 reason people go back to bottled water after buying cheap filters: the taste doesn't improve.
Honest verdict
For 80% of European pilgrims and users, GoPure is the best decision. Because of improved taste, long lifespan, capacity, design. The €20 extra over LifeStraw pays back in daily quality of life.
LifeStraw stays a great option if budget is tight or if you're going to already-clean water (high mountain).
Katadyn BeFree is specifically for trail runners and extreme minimalists. If you're one, it's the only real pick.
There's no bad choice among the three. Only the right choice for your scenario.
