Best praise vs top criticism for MSR Guardian Purifier
Top Criticism
+2 pts“Supposedly the guardian series was developed for a military contract but they sell a civilian version? Either way for the price it seems a regular filter and tablets should be pretty good value and compact. The guardian is like $400 :/ At the end of the day IDK any portable solution short of a zero water pitcher and full size cartridge you could use to get absolutely everything for a reasonable sum of money”
