A Portable Water Purification System for People on the Move
Ideal for backpacking, travelling, hiking, fishing or any other outdoor activity where storage space is limited and lightweight is key, the original LifeSaver Bottle, invented by Michael Pritchard MBE was the world's first portable water purifier, and has been saving lives for over 15 years. Our water purifier bottle allows you transform the dirty water found in rivers, lakes, streams and ponds into safe drinking water - without the use of water purification tablets or power. Simply fill, pump, drink.
The Ultra Filtration water purification system safely removes 99.99% of viruses, bacteria, parasites and microplastics to leave you with clean, clear, SAFE drinking water. Our patented FailSafe Technology stops water from passing through a filter that needs replacing so you'll know exactly when you need change it over. Add an activated carbon filter and the taste will improve too!

The LifeSaver Bottle is an essential part of many military kits including the US army. Together with the LifeSaver Jerrycan, our products have helped keep soldiers safe when deployed overseas and living in challenging conditions.
