Membrane Solutions Gravity Water Filter Bag 1 Gal (OESF034_M) is a compact, gravity-fed filtration system designed for outdoor enthusiasts and emergency kits. It uses a water straw and a four-stage filter to deliver safer drinking water from uncertain sources.

• Capacity: 1 gallon (3.8 L) bag for easy, portable filtration at the campsite or on the go
• Filtration system: Integrated water straw with a four-stage filtration process to reduce particulates and improve taste
• Filtration life: Up to 5000 L of water between filter replacements

This system provides reliable access to clean water wherever you are—camping, hiking, road trips, or emergencies—without relying on powered equipment. The gravity design makes setup simple: fill the bag from a water source, hang or place it to let gravity do the work, and collect purified water as it streams through the four stages. The 5000 L total filtration capacity helps extend use over multiple outings, reducing the need for frequent filter changes. By filtering at the source, you can minimize plastic bottle waste while enjoying clearer, better-tasting water. For best results, use the straw to draw from a trusted source and store the bag sealed after use to maintain water quality.
