What Redditors Say
Best praise vs top criticism for Sawyer Squeeze
Best Praise
+114 pts“My Squeeze has been going great since 2018. I had a few moments of slow flow some years ago but I've resolved that... Anyway, how are you back flushing it? Are you prefiltering the water with something like a folded bandana? If you've had the same problem with multiple filters, it's not likely to be a defective product so you're asking the right question.”

ViewTop Criticism
+22 pts“Had this happen when with a filter I believed to be fully dried (air dried for 2 weeks) at the end of a summer season. Made me dubious it's even possible to for a squeeze to be fully dry inside after it's been used.”

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”
