>>2422748MSR are my preferred for lightweight, trail shot or gravity works. For volume and purification either the MSR Guardian or LifeSaver Jerrycan. Katadyn befree is good too. The three brands I mentioned above have actual research and development departments. Kartadyn has relatively old designs except for the Befree but that’s the Swiss for you. Everyone else buys off the shelf membranes and just hires industrial designers - this includes lifestraw, sawyer, and grayl.
>>2422750Sure water come out of it, but it’s sure as hell not clean water by litre 10,000.
>>2422753You won’t find it online, but it’s well know in the industry. I have proof but can’t post it. Call me a faggot, and don’t believe me if you want. Summary of the report I have says that the grope was let fecal bacteria and E-coli through even with a brand new filter, getting worse with every use.
>>2422807The be free is decent. Trail shot is good too. Or a platypus gravity they use MSR filters.
