The LifeSaver Liberty Water Filter Purification Bottle is a two-in-one piece of gear. This water-purifying bottle holds up to 400 milliliters of water for you to carry with you in the outdoors. Additionally, you can use this water bottle as a portable filtration system. With a two-part system including carbon and a hollow fiber membrane, this water-filtering bottle removes nearly 100% of toxins, bacteria, and pathogens from your water. That could be lifesaving when you’re out in the wilderness on a long backpacking trip. With a built-in inline pump, this water purification bottle pumps at a rate of 1.2 liters per minute. And it’s convenient to use because it has a five-foot scavenger hose. Filter up to 2,000 liters of water before you need to replace the carbon filter. Finally, you can easily attach this bottle to your carabiner and hit the trail.
