Platypus GravityWorks Water Filter System 4 liter

High-capacity, pump-free water filtration for groups and basecamps
Filtering up to 1.75 liters a minute without any pumping, the high-capacity GravityWorks Water Filter System filter is one of the easiest and fastest ways to get filtered water in the backcountry. With two different sizes-6.0L & 4.0L-the GravityWorks is ideal for bigger backpacking groups or basecamps. Offering an 8 or 12 liter total capacity, either model easily supplies filtered water for drinking, washing up, cooking, and cleaning. Simplify your water collection with the GravityWorks system and spend more time enjoying your group.
