The GB2 Millbank Bag is the perfect, personal-sized prefilter/clarifier for your kit. This smaller version is sized to easily fold up and stow in your pocket, water bottle carrier, haversack, or pack.
Designed with the camper, hiker, backpacker, and bushcrafter in mind, the GB2 Millbank Bag is the perfect companion for your Grayl GeoPress or other water filter or purifier. Prefiltering, or clarifying your water prior to putting it through your filter will drastically increase the life of your filter or filter cartridge.
The heavy duty canvas bag will remove most dirt, debris, particulates, and suspended organic material in the water that waterborne pathogens like to attach themselves to. This will improve taste and odor regardless of the method you choose to disinfect.
This Millbank Bag Water Prefilter bag, like all cloth or canvas bags, does not achieve the necessary micron-level for disinfection by mechanical filtration, so it is important to note that this is a prefilter that clarifies water to improve taste, odor, and overall palatability. It also increases the life of and effectiveness of your filter. It DOES NOT make water safe to drink. You must still disinfect it in some way using a filter, purifier, chemical, or thermal means.
