Overview
Built to keep an existing Guardian gravity system working at full capacity, this replacement cartridge is a practical choice for hunters and backcountry travelers who need dependable water treatment in the field. It is also a sensible spare to carry when extended trips or remote camps leave little room for equipment failure. The cartridge is designed to deliver high volumes of purified water on demand and includes activated carbon to help reduce unpleasant tastes and odors. It is intended for use with the MSR Guardian Gravity Water Purifier sold separately, so it fits best as a maintenance or backup component rather than a standalone purifier.
