Introducing the stylish LifeSaver Liberty

A Flexible Travel Bottle Solution

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.

Range of Options & Accessories

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.
