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.\n\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Membrane Solutions","offers":[{"title":"Default Title","offer_id":52095824855334,"sku":"MSLOESF034","price":29.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0859\/9211\/2422\/files\/MSLOESF034.jpg?v=1771702764"}],"url":"https:\/\/blackcountryoutdoor.com\/collections\/membrane-solutions.oembed","provider":"Black Country Outdoor","version":"1.0","type":"link"}
