Produced by the renowned brand Membrane Solutions, this gravity emergency kit is perfect for camping, survival camps, and bushcraft expeditions. It also serves as an indispensable piece of gear for a Bug Out Bag (BOB) and as an excellent safeguard in the event of natural disasters or sudden municipal water supply failures.\u003c\/p\u003e\n\u003cp\u003eThe system's design is based on an innovative combination of two independent and replaceable filter elements. The first stage of protection is an advanced \u003cstrong\u003eHollow Fiber\u003c\/strong\u003e membrane with pores as small as 0.1 microns, which acts as a physical barrier against pathogens. It effectively removes up to 99.99999% of harmful bacteria, 99.99% of waterborne parasites (protozoa), and up to 99.999% of microplastics from the water, while also retaining solid contaminants such as silt, sand, and rust. The second stage is a \u003cstrong\u003ereplaceable carbon filter\u003c\/strong\u003e with a coconut fiber coating. The activated carbon effectively reduces heavy metals, chlorine, and organic chemical compounds, while significantly improving the taste, clarity, and odor of the filtered water.\u003c\/p\u003e\n\u003cp\u003eThe heart of the gravity kit is the personal \u003cstrong\u003eStraw I\u003c\/strong\u003e filter, which is connected to a flexible and durable, high-capacity \u003cstrong\u003e3-liter\u003c\/strong\u003e water bag. The system operates fully autonomously using the natural force of gravity—it requires no external power source, pumping, or harmful chemicals to function. Simply fill the bag with untreated water from a river, lake, or stream, hang it using the included strap, and connect it to the straw filter with the silicone tube. The device offers an optimal water flow rate of up to 450 ml per minute, allowing for efficient supply of drinking water for an entire camping group.\u003c\/p\u003e\n\u003cp\u003eThe filter housing is made of a lightweight, durable, and impact-resistant \u003cstrong\u003eBPA-free polymer\u003c\/strong\u003e, which guarantees full health safety and no leaching of toxins. The entire set is characterized by its compact dimensions and low weight (only 315 g), making it easy to fit into any hiking backpack. The included cord with a handy plastic clip allows for easy and stable hanging of the reservoir on a tree branch or tent structure. The system meets rigorous \u003cstrong\u003eSGS and US EPA\u003c\/strong\u003e safety standards, confirming its top quality and reliability in the most difficult crisis situations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Original product created by the renowned Membrane Solutions brand.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eModel and product code:\u003c\/strong\u003e Gravity water filtration system, manufacturer code OESF005.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eReservoir capacity:\u003c\/strong\u003e Durable and spacious water bag holding exactly 3 liters of liquid.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eProduct weight:\u003c\/strong\u003e The total weight of the complete kit is only 315 g.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFilter weight:\u003c\/strong\u003e The personal straw filter weighs just 57 g.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFilter dimensions:\u003c\/strong\u003e Compact straw housing with exact dimensions of 170 x 30 x 30 mm (17 x 3 x 3 cm).\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-quality medical-grade polymer completely free of harmful BPA.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFiltration technology:\u003c\/strong\u003e Four-stage system (screen, cotton fibers, coconut activated carbon, Hollow Fiber membrane).\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMembrane effectiveness:\u003c\/strong\u003e Removes up to 99.99999% of bacteria, 99.99% of parasites, and 99.999% of microplastics 0.1 μm and larger.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFiltration capacity:\u003c\/strong\u003e The integrated Hollow Fiber membrane has a lifespan of up to 5,000 liters of purified water.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eCarbon filter lifespan:\u003c\/strong\u003e The replaceable activated carbon cartridge is effective for up to 100 liters of water.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eWater flow:\u003c\/strong\u003e Maximum gravity filtration speed is up to 450 ml per minute (450 ml\/min).\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eQuality improvement function:\u003c\/strong\u003e Activated carbon reduces chemicals and effectively improves the taste and smell of water.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eSafety class and standards:\u003c\/strong\u003e Compliance with rigorous quality standards from SGS and the US EPA.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eOperating principle:\u003c\/strong\u003e Fully gravity-fed filtration without the use of chemicals, batteries, or the need for pumping.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eSet contents:\u003c\/strong\u003e Straw I filter, 3L bag, hanging strap, silicone tube, plastic clip, and carrying pouch.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eColor:\u003c\/strong\u003e The kit components feature a universal blue finish (Blue).\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Indispensable for survival, bushcraft, mountain hiking, camping, and as emergency gear.\u003c\/li\u003e\n\n\n\u003c\/ol\u003e","brand":"Membrane Solutions","offers":[{"title":"Default Title","offer_id":52546314535253,"sku":"6977645370048","price":43.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/6560\/1109\/files\/Membrane-Solutions-Filtr-grawitacyjny-3L-Niebieski-1.jpg?v=1770828485","url":"https:\/\/beonwin.com\/en-eu\/products\/membrane-solutions-filtr-grawitacyjny-3l-niebieski-czysta-woda-na-biwaku-i-w-sytuacji-awaryjnej","provider":"BeOnWin","version":"1.0","type":"link"}
