Easily purify and filter gallons of water at camp or on the go with the Trail Blazer Gravity Purifier. The ideal camping water treatment system, this gravity water purifier kit includes a 9 liter bag, hose, and 6.5" RapidPure filter cartridge. Unlike microfilters that rely on pore size to simply filter out bacteria and sediment, RapidPure water treatment actually purifies water using electroadsorption, removing bacteria, parasites, viruses, parasites, chemicals, heavy metals, pesticides, and microplastics, as well as filtering out sediment. Thanks to this technology, the Trail Blazer features the fastest flow rate of any gravity water filter on the market, purifying and filtering up to 5 liters of water per minute, all without any batteries, pumping, priming, or special maintenance. RapidPure continues to work even after it has been frozen, giving you peace of mind if the temperature suddenly drops. With RapidPure water purifiers, quenching your thirst is safer, faster, easier, and better tasting.
