Gear Review: Water-to-Go Filter Bottles – A Hiking and Wild Camper's Essential
When you're out hiking remote trails or wild camping far from the nearest tap, clean water becomes a non-negotiable. That's where the Water-to-Go filter bottles step in – and after weeks of use across trails, streams, and one very questionable puddle, I can confidently say they've earned a place in my kit.

What Is Water-to-Go?
Water-to-Go bottles are reusable water bottles with built-in filtration technology that removes up to 99.9999% of contaminants, including bacteria, viruses, protozoa, chemicals, and even microplastics. Designed initially with NASA tech, the filters are effective against pretty much anything nature (or human pollution) can throw into a water source.
Why Water-to-Go Is More Than Just a Hiking Filter Water Bottle
The Water-to-Go bottle is designed for one purpose: to turn unsafe water into clean, drinkable water—instantly. Whether you're refilling from a stream in the Scottish Highlands or a river in the Alps, the built-in filter removes:
✅ Bacteria
✅ Viruses
✅ Protozoa
✅ Microplastics
✅ Heavy metals and chemicals
It's a lightweight, eco-friendly alternative to disposable bottles or bulky pump filters, and a serious upgrade from chlorine tablets. These bottles are also handy for foreign travel when you are unsure if the drinking water is safe (I even use these bottles in my work office!)

How It Works
The filter uses a combination of mechanical filtration, electrostatic charge, and carbon. It starts working as soon as you fill the bottle and take your first sip. No pumping, no tablets, no waiting – just fill and drink.
Which Bottle Is Right for You?
There are two main Water-to-Go bottles perfect for hiking and wild camping:
750ml Eco Active Bottle (£37.99):
Squeezable bottle for rapid water delivery
Each filter lasts for 200 Litres.
Includes a detachable clip for a carabiner
New single-handed action click lid
Lid covers entire drinking area for hygiene
Weighs just 138 grams
BPA Free
Filter 100% recyclable

500ml Classic bottle (£24.99):
Filter lasts for 200 Litres
Replaces 400 single-use plastic water bottles
Weighs just 98 grams
BPA Free
Filter 100% recyclable
Bottle NOT dishwasher safe
Field-Tested on the Trail
I tested the 750ml bottle during a multi-day solo hike through the Lake District and then again during a wild camp in the Yorkshire Dales (I also use it at work!). Highlights?
Ease of Use: Simple and intuitive. Fill from a stream, screw the lid on, drink.
No Aftertaste: Unlike chlorine tablets, there's no weird chemical flavour – just clean, neutral-tasting water.
Weight: At just 138g (for the 750ml model), it's ideal for lightweight hiking setups.
Eco-Friendly Bonus: No need for single-use plastic bottles. That's a win for you and the planet.
Replacement filters are £16.99 and need changing every month or 200 litres.
Downsides?
Not many, but worth noting:
The flow rate is a little slower than a regular bottle – you won't be guzzling water fast, but that's the trade-off for thorough filtration.
It's not designed to filter large quantities (like if you need to cook or refill a hydration bladder). However, you can squeeze the water into another container.
Why It's One of the Best Hiking Water Bottles for 2025
This bottle provides all the essentials for solo hikers, backpackers, and wild campers: clean water, minimal weight, and simplicity. It also massively reduces the need for plastic bottles—perfect for anyone hiking with a focus on sustainability.
Final Thoughts
Suppose you're hiking in the UK or abroad, especially in areas with uncertain water sources. In that case, a Water-to-Go bottle is a smart, reliable companion. It simplifies water safety without adding weight or faff to your pack. I've permanently clipped it to my rucksack, and I wouldn't camp without it.
