Enjoy total flexibility with the LifeSaver Liberty™ - the world's first and only portable water purifier which is a bottle and an inline pump combined. Using the same advanced filtration technology as the original LifeSaver bottle, the LifeSaver Liberty™ water purifier bottle is a smaller, lighter more versatile version, whilst still robust and easy to use. Fill it up with water to drink on the go and fill your hiking buddies' bottles too. Simply fill, pump, drink.
The best water purifier bottle for outdoor enthusiasts, travellers, backpackers or anyone who needs a reliable source of drinking water. Stocked in a choice of colours, Liberty is supplied with a 5ft scavenger hose (so you don't get your feet wet), a replaceable filter cartridge and an activated carbon disc to improve the taste of the water and remove a few more potential nasties. You can also add a soft silicone sleeve to protect your LifeSaver Liberty from scratches and nicks and a hydration bladder connector.
Travelling with Liberty
On an extended backpacking adventure or gap year? Chances are, at some point you'll be staying in a dodgy hostel or setting up camp somewhere. And whether the water is coming from a river, standpipe or a shared kitchen, it's best not to take any risks.
Or maybe you are travelling in comfort but heading to a part of the world where the tap water is not as trustworthy as you're used to?
Either way, you don't want to be far from home without a replacement filter. We can send spares almost anywhere in the world but tracking you down could be a challenge! Choose a pack that has everything you could possibly need.

Everything you need to know about the LifeSaver Liberty water purification system
The LifeSaver Liberty uses advanced filtration technology to remove 99.99% of viruses, bacteria, cysts, parasites, and microplastics from contaminated water. Simply fill from any freshwater source, pump to activate the filtration system, and drink clean, safe water. No batteries or power required.
Each cartridge is capable of purifying up to 2,000 litres of contaminated water before needing replacement. The cartridge has an integrated failsafe mechanism that prevents water flow once it reaches capacity, ensuring you never drink unfiltered water.
The LifeSaver Liberty has a 400 ml capacity - about the same as a can of soda.
Rinse the Liberty with clean water periodically. Replace activated carbon filters as needed for fresh-tasting water. When the cartridge reaches 2,000L capacity, it will automatically stop flowing - simply replace with a genuine LifeSaver replacement cartridge. Store in a cool, dry place when not in use.
The LifeSaver Liberty is designed for use with freshwater sources such as rivers, lakes, and streams. It removes harmful contaminants including viruses, bacteria, cysts, parasites, and microplastics. Do not use with saltwater or chemically contaminated water.
Along with essential replacement parts - cartridges, spare activated carbon filters - we also offer a range of accessories to help you get more from your Liberty.
The LifeSaver Liberty is the ideal solution for backpackers heading for Asia, Africa or South America, offering a flexible water solution wherever your adventure takes you.
The LifeSaver Liberty is designed and manufactured in Great Britain with unrivalled quality and precision engineering. Each unit meets stringent quality standards and certifications.
