The end result is a proven, high quality product. The "Brown" Millbank Bag is an excellent place to start when purifying water. It acts as a pre-filter to remove particulate matter from water. The more detritus water has in it the harder it is to purify so you can put the prescribed amount of puritabs into muddy, dirty water but it still won't make it safe.
This product would be ideal for outdoor enthusiasts, campers, or hunters who require a reliable, high-quality filtering solution.
