British Army - Bolsa Filtro de Agua Británica Millbank usada

The British Millbank water filter bag is a reliable companion for emergency preparedness. Originating from British Army stocks, it is used but in good condition.
With its practical hanging loop, the filter bag can be stored in a space-saving manner and is always ready for use. Whether camping, hiking, or in an emergency situation, this filter bag cleans water of solids and makes it drinkable.
The application is simple: Fill the bag with water, place a container underneath, and wait 5 minutes. The Millbank filter bag pre-filters water, removing suspended solids but not microorganisms or chemical residues. To make the purified water safe to drink, it must be boiled or treated with water purification tablets after pre-filtration. Because the filter bag has already removed suspended solids, the water filter cartridge will last longer. After use, thoroughly clean the filter bag and allow it to dry.
