I travel a lot for work — about eight international trips a year, mostly to Europe and occasionally further afield. I also hike regularly at weekends, mostly in the Peak District and occasionally in the Alps when I can arrange it. Both activities have the same problem: staying hydrated without generating a trail of single-use plastic bottles.
I’d been buying bottled water on every trip for years. Not because I wanted to — I was aware of the environmental impact and felt guilty about it every time — but because I didn’t trust tap water in every country I visited, and I didn’t have a better solution. The LifeStraw Go Series Insulated Water Filter Bottle is the better solution. I’ve been using it for ten months and I haven’t bought a single-use plastic water bottle since.
The Single-Use Plastic Problem
The specific issue with international travel and hydration is that tap water safety varies significantly by country. In the UK, Germany, and the Netherlands, I drink tap water without hesitation. In some other countries I visit for work, I’d been less confident — not because the water was necessarily unsafe, but because I didn’t know enough about the local water quality to be certain. The default response to that uncertainty had been to buy bottled water, which is expensive, inconvenient, and generates plastic waste that I found increasingly difficult to justify.
I’d been aware of filter bottles as a category for a while but had assumed they were primarily for outdoor use — filtering stream water on hiking trips rather than tap water in cities. The LifeStraw Go is designed for both, which is the combination I needed.
Why the LifeStraw Go Specifically
LifeStraw is the brand that serious outdoor and travel communities trust for water filtration. Their filtration technology is used in humanitarian contexts — providing safe drinking water in areas without reliable water infrastructure — which is the most meaningful endorsement of filtration effectiveness I can think of.
The dual filtration system was the specification that made the LifeStraw Go Series Insulated Water Filter Bottle the right choice. The membrane microfilter removes 99.999999% of bacteria, 99.999% of parasites, and 99.999% of microplastics — the contaminants that make water unsafe to drink. The carbon filter removes chlorine, odours, and organic chemical matter — the things that make water taste unpleasant even when it’s technically safe. Both filters together mean the water is safe and tastes good, which is the combination that makes you actually drink enough.
The filter longevity was the practical specification I looked at carefully. The membrane lasts up to 4,000 litres — at my consumption rate of about 1.5 litres per day, that’s over seven years of daily use. The carbon filter lasts 100 litres, which at my usage is about two months. The replacement cost of the carbon filter is low, and the membrane essentially never needs replacing for a normal user. The economics of the LifeStraw Go versus buying bottled water are dramatically in favour of the filter bottle.
The insulated stainless steel construction was the quality specification that distinguished this from cheaper filter bottles. Stainless steel is durable, doesn’t retain flavours, and is BPA-free. The insulation keeps cold water cold for hours, which matters on a hot day hiking or in a warm city. The 24oz (710ml) capacity is the right size for a day’s hiking or a long travel day.
I found it in the Hydration Systems and Outdoor Recreation collections, and also in the broader Sporting Goods range. It arrived three days after ordering.
First Trip — Three Days in Lisbon
My first trip with the LifeStraw Go was a three-day work trip to Lisbon. Lisbon tap water is technically safe to drink but has a strong chlorine taste that makes it unpleasant. I filled the bottle from the hotel tap every morning and drank filtered water throughout the day. The chlorine taste was gone — the carbon filter removes it completely. The water tasted clean and neutral.
I didn’t buy a single plastic water bottle in three days. I refilled from taps in the conference venue, in restaurants, in the hotel. The bottle kept the water cold for several hours, which in Lisbon in September was genuinely useful.
I came home having saved about twelve plastic bottles and approximately £18 in bottled water costs. Over ten months of travel and hiking, those numbers have accumulated significantly.
Ten Months On — The Honest Verdict
Ten months of daily use across six countries and multiple hiking trips. Here’s the honest report:
- I haven’t bought a single-use plastic water bottle since I got it. Ten months, six countries, multiple hiking trips. Every drop of water I’ve drunk has come through the LifeStraw filter. That’s the primary goal and it’s been achieved completely.
- I’ve drunk from a mountain stream. On a hiking trip in the Alps, I filled the bottle from a stream and drank it without hesitation. The water tasted clean and I had no ill effects. That’s the filtration working as designed.
- I’ve drunk from an airport fountain. Heathrow Terminal 5, which has noticeably chlorinated water. Through the LifeStraw filter, it tasted fine. The carbon filter earns its place.
- The stainless steel construction has held up to ten months of travel. Packed in bags, dropped occasionally, used daily. No dents that affect function, no rust, no degradation of the seal. It’s a robust piece of kit.
- I’ve replaced the carbon filter once. At the 100-litre mark, as recommended. The replacement is straightforward and the new filter restored the taste improvement immediately.
- I haven’t been ill from water once. Six countries, a mountain stream, airport fountains. The filtration has worked correctly every time.
The Difference It’s Made
I travel without guilt about plastic now. That’s the honest summary. The low-level guilt of buying plastic water bottles on every trip — knowing the environmental impact, doing it anyway because I didn’t have a better option — is gone. The LifeStraw Go is the better option I’d been looking for. It’s also saved me a meaningful amount of money over ten months, which is a bonus I hadn’t fully anticipated.
If you travel regularly or hike and you’ve been buying single-use plastic water bottles because you don’t trust tap water everywhere, the LifeStraw Go Series Insulated Water Filter Bottle is the solution. Browse the full Hydration Systems and Outdoor Recreation collections for more options.
Fill it from the hotel tap. Drink it. Notice that it tastes fine.
Then stop buying plastic bottles.
