LifeStraw, a public health B Corp on a mission to provide equitable access to safe drinking water, announces the launch of its large capacity Peak Series 8L Gravity Water Filter Systems, designed for extended use in the outdoors and backcountry offering both high capacity, high flow rate filtration and leak-proof water storage in an ultra-durable dromedary style bag.

Designed for camping, RVing, overlanding and adventure travel, the Peak 8L Gravity Filter can be used independently, or together with the 8L Safe Water Storage bag doubling the capacity of the whole system to 16L. The 8L design can function as both a leak proof dromedary storage bag and a water filter system capable of filtering all 8 liters – removing bacteria, parasites and microplastics from water – in under 10 minutes. The system hangs from a tree or RV for quick hydration at basecamp and easy carrying options requires only one group member to carry water for the entire crew.  

“With over three years of development, this is the most versatile and robust outdoor system LifeStraw has ever made for reliable access to safe water in the backcountry.” said Alison Hill, CEO of LifeStraw. “It has also quickly become a staff favorite for those of us who go group camping with lots of kids and family in tow. Our van life friends have also been asking when they can get their hands on one.  It was a huge goal to take the complication out of having to store and carry water separate from filtration. This system allows for everything in one.”
