MSR Guardian Water Purifier Replacement Filter Cartridge


Brand MSR

Over time the filters hollow fibers become blocked or partially blocked as they remove viruses, bacteria, protozoa, and particulates like dirt and sediment, reducing flow rate. A new filter cartridge will have your Guardian performing like new.

  • Kit Includes: Guardian Purifier Replacement Cartridge, Clean Side Cover, MSR Food-Grade Silicone Lubricant, and Instructions.
