MSR Guardian Water Purifier Replacement Filter Cartridge


We accept Afterpay and Zip ($100min/$1000max)

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.
